If there's one thing I've learned from YT maker videos it's that making your own stuff is educational and also a fantastic way of flushing a lot of time and money down the toilet.
@@InheritanceMachiningBeen watching since your first video dropped. Both are fine but your storytelling style is distinctive and I feel like fits in the theme of your channel. I did like this format as I don't think we've ever heard so much from your wife before.
@@jacobwebber9821 Absolutely! I was supposed to suggest that. A 3:1 ratio where 3 represents storytelling. I've been here from the beginning, and I must say that the storytelling was so "intimate"-just a man and his steel 🙂
Yeah the orbital sander on fire brick scene, with no respirator, had me sweating. This is my first video on this guy's channel, and I already love his work, but this was the most serious safety issue I've seen in a DIY/maker video in a long time...
@@watcheater9229 I'm not really sure how that's relevant. I'm not an engineer, and yet I always make a point to research anything I'm working with on a DIY project before hacking into it with power tools. And in fact, that's how I came to know that the primary ingredients in refractory bricks are alumina and silica, neither of which you want inside your lungs.
The amount of support your Ms. provides, even in setbacks, are astonishing. No matter how many tools you add, she's still the best resource you have in that shop.
Good build. At the risk of repeating other comments a couple of suggestions for when you build the bigger one (you know you will need one). Use powder air-set refractory mortar rather than premix to save money. First use, heat up slowly, step to 110C and hold for about 4 hours to eliminate moisture, then ramp at 50C per hour to about 800C. Bricks expand and could stress the metal case, wrap the IFB with a layer or two of ceramic fibre paper to form a compressible spacer, this will also increase insulation and reduce the case temperature. Tune the controller yourself manually, auto_tune rarely gives the best results, there are plenty of good tutorials online, a lot of cheap controllers have variations on gain scheduling which can help with quick heat ups..
Great advice, I indeed thought that moisture should ve evicted slowly. Maybe additionally measure the humidity in the shop, then you can better estimate the duration of the warmup cycle. Loved to see all the work that went into it, gorgeous (bit tight) door mechanism!
Great finished product! For everyone else, who might build one-- bring the temperature up slowly to 95⁰C and hold there to allow most of the moisture to evaporate, then move to 105⁰ for about an hour to finish drying the firebricks. This will greatly reduce the fine cracks that you found in your's after your first use. Remember, water expands almost 1000 times in volume in its change from liquid to steam, so a small amount of water turned into a whole lot of steam and it had to find a place to get out. Failing to find a way out, the steam just made one!
I was about to write the same thing! Maybe even better is to gradually rise until 800°C in like a day or so. There is a gradient of temperature in the bricks, so you might have dried the interior of the over but the core of the bricks is still moist if you only go to 105°C.
"Failing to find a way out, the steam just made one" Just like ice... Either it has enough space to expand, or it will make some. Regardless of how much you like that water bottle..... 😢
"Is this just a scope-creep or was the scope stupid from the beginning" is what I'm being asked by my manager whenever I'm presenting a new device I've designed at work. I'm going to make a banner out of it and hang it over my seat at work. Hats off for a complex project very well done and thanks for sharing!
I've been there, needed or wanted something, decided to build it. Days, weeks later I finished, was proud of what I made and how I made it, functioned exactly how I planned, but realized how much money I spent on it, hours put in, when I could have bought one for half the price. However years later it still functions same as it did on day one. Never know what you are buying, how long it'll last. Great work, looks great, works like you wanted, and you built it.
No other channel in this side of youtube is able to combine the quality of work, video production, charm and personality, and storytelling that you TWO manage with every single video. Brilliant stuff.
I have been tinning for 35 years. Long surface area's with small machines/equipment generally don't work out well, material thickness and malleability of the materials make a big difference as well. I was actually impressed that he was able to get it to turn out as well as he did, not meaning that to be negative.
Or he could return the machine and build his own, better roller >:D To achieve both high rigidity and ability to make small-ish corners you need to double the amount of rollers. A large diameter thick wall pipe pressing on a smaller cylinder that then acts on the sheet metal. This way the actual "tool edge" is supported along it's entire length and won't bow, allowing for more consistent bends.
I'm intrigued to know your process of developing a project like this. I normally do 10 designs in CAD before making 3 very fast and cheaply made prototypes before settling on my final quality design. You look like you just went for it and aimed for perfection from the start. Cheers J
Man, where's your PPE!? We're going to end up calling you Inheritance Silicosis after this... These bricks will shatter when thermally shocked hard like that, straight from cold and moist. Not a big deal if the frame holds it together. You might also want to run an auto-tune on the controller, to get it going up to temp faster and have it be more stable there. Run the autotune at approximately the median temperature you expect the oven to heat to most of the time.
Yeah, I am like that dust is never coming out of his lungs now. Hopefully he was not exposed to it for too long. If you are working with dust get a respirator on, hell a dust mask will be better than rawdogging that silica dust.
My inner QA/safety brain was screaming at the dust. I even use an N95 while doing simple wood routing, much less when I was repairing my chimney. The next big shop project should honestly be a vent system (smoking hot metal and micro particulate is its own serious issue) and easy reach PPE storage. I fully understand how annoying that is with a full beard (I've given up trying to shave myself clean given an five o'clock shadow about 7 hours too early), but organ damage in both short and long term is absolutely terrifying. I've read enough clinical horror stories on metal neurotoxicity to know not to screw with it.
The interview style format with your good lady along with the 'this is a bit out of my ballpark' but then achieving it is awesome dude. The comment on how your thing is mechanisms and then you speed montage through the mechanisms without narration bit was a nice touch! although you did miss the chance early on (7:55) to use the rotary to cut the radius in the bricks, and filling the rotary with silicone dust would have guaranteed the next project has at least 1 side project 'service the giver of pretty chamfers' lol. Look forward to seeing the oven in action!
Having spent a decade in heat treating and aerospace sheet-metal, I can write this say: outstanding job! Suggestions: 1) When you are bending, bend with the grain set diagonally or perpendicular to the direction of the bend. 2) some light sanding at the edges of your bend axis will reduce likelihood of cracks propagating from the edges. 3) I guess you bought 2024-T 42 sheet metal for the shell. I don’t remember guidelines on bend radius ratio. But I think it is radius must be at least 2x the thickness when bending in the T42 condition. It may be 3X though. 4) your shell might warp overtime and make door ceiling difficult. A very simple titanium mesh, or braided fiberglass rope will make an excellent door seal. 5) Oven controls: you should have completely separate pyrometers for the monitoring and controlling the set point. Especially if you use K type thermocouples. Probably will not be such a problem if you use N type thermocouples. 5) Warning on K type thermocouples: don’t use them! They have terrible drift above 500 degrees Fahrenheit due to the electro mechanical properties
@@Ammoniummetavanadatesomething being a standard doesn't say anything about how good a fit it is for a specific use case. Type K thermocouples have plenty of uses, but they are not a particularly great choice for this situation, as this oven will be operating at temperatures high enough to cause permanent drift, which leads to lower temperature readings over time. I'm sure that a type K would work just fine in this situation, because as a hobbyist the tolerances are large, and volumes are low. Typical lifetime drift for type K MIMS thermocouples is on the order of 20 degrees F. In an industrial setting, this does matter, but in a home hobbyist shop, it's much less of a concern. Still, it certainly wouldn't hurt to use the better option if it's available and not significantly more expensive.
@@Bobbias I use hundreds of type K thermocouples daily in industry. Also a lot of type B, J, and rtds for cryo. Tolerance of type K is at best 0.4% so at 800C or 3.2C and more realistically is 0.75% which is 6C. Type N TCs have roughly the same tolerance at 800C. Your type N will also need to be calibrated and cross checked. If he was operating in a reducing or vacuum environment sure the type N is a bit better but type K is totally fine for this oven. If you are seriously concerned about getting an accurate temperature you employ multimeter dissimilar measurement devices. I personally have a very very sensitive type R thermocouple that is heavily shielded and connected to an extremely precise amplifier that I cross check my other TCs with as well as a triple point calibration system I built for bench calibration. In short type K is fine, always cross-check your instruments.
@@Ammoniummetavanadate I assume you meant to say "multiple dissimilar measurement devices"? Good option if practical. Type R (costs a bit more) is more linear & stable -> more accurate, but technically is less sensitive in terms of uV/°C, not that it matters if you use a good indicator. @marshallwilliams4054 For amateur workshop fabrication use this probe will probably be fine, it doesn't need to meet some aero alloy HT spec, would have been nice to add an overtemp cutout though.
25:25 is the best compliment anonye who makes his own stuff can get loved the interview style, i think a good mix of interview style for story, and voiceover when talking about technical stuff would be just perfect!
My wife, watching in the background, echoed every 'OOOOOHH' with one of her own, and then cackled. 'She says the same thing to him, like I say to you when you make stuff!'
@@aaronbuildsa just a note, unfortunately youtube is stupid and you have to leave a space between your quotation mark and the underscore. like " _this_ ". i know, frustrating.
Once again, your timing was impeccable. To say this had been a crappy week at work would be to damn it with faint praise. And just when I needed to see a fun project done by fun people, you delivered. Thank you.
I ran into the same problem trying to bend some thin (3/16") 6061-T6. The solution is to anneal it; but how? Basically mark where you want your bend, and then paint a 1" wide stripe of brand name black Sharpie marker along that line. Hit the other side of the aluminum with a MAPP torch, playing the flame back and forth along the back side of the line. At some point, the band of Sharpie marker on the other side will begin to "evaporate" and turn from black to a translucent gray. This is the annealing point. Go much hotter and aluminum will begin to pucker or melt. Do this the same day as you plan to make your bend, as some alloys can "precipitation harden" over time and undo your annealing. It worked beautifully for me; no cracks, no splits, just nice smooth bends. Thanks for an amazing video. That was a beautiful build. Oh and making that coil with the drill and jig? Absolute nerdgasm over here.
Soot from an acetylene torch works as well. Just coat the area you want to anneal in soot and heat till the soot dissappears. It's slightly faster to apply then the sharpie method.
Read this two seconds after I posted. You are right on. I worked 46 years in a series of different positions. Every piece of metal takes a different procedure.
wow that's impressive! The bricks cracked because of moisture trapped inside them. That's why you have to ramp the temperature up slowly step by step to dry them. The kind of procedure we use on new pizza ovens. Biggest ones can take 2 days doing that
You dont realize how happy i was when i saw you finally uploaded again. I recently discovered your channel and watched all of your videos( yes. all). Thanks mate
"What if you need to heat treat something wider than that?" "You don't" 🤣 Seriously though that was an awesome build. Your videos are the ones I'm most excited to watch. I learn something that I might be able to use (various techniques you use) and get to see cool builds come together in the most satisfying way
Makes sense though. The larger you make the inside, the more energy it takes to heat up and maintain that heat. You build your heat treat ovens just big enough for the objects you plan on heat treating, no bigger.
The knowledge you got from making this oven is priceless. It's worth more than the money you need to just buy one. And in the comment section you learned the hazardous dust of the oven bricks and they break up due to the heat cycles.
I'm an engineer for a company who makes sheet metal enclosures. So, its funny to see what problems you run into, looks very good though! For next time: to bend the large radius this is best done on the (bend) press. Eighter make a series of small bends close together, like 10x9 degrees, or make a bend tool with the desired radius instead of the V shape.
really love that your wife is keeping you company all the way through, and enjoying it! as a fabricator, I'd go insane without a couple people in the shop to keep me company.
This video is like watching an interview of myself doing the same thing, but over 2 years! Between using my drill press as a brick router, 5 failed attempts at making proper coils, replacing crappy/rekt thermocouples, burning out a couple relays, etc. It was by far my most problematic build so far. doing the calculations for W/cm3 had me feeling like a scientist. Now my oven gets to 1100C in 15 min, and ive heat treated dozens of knives precisely. Watching this video was cathartic. knowing someone else has been through what I've been through. Well played, and enjoy!
Pro bending tip! The sharp tool did't help, but .. the bed radius was still too tight. The bend radius is determined by the width of the V not the sharpnedd of the tool. Most tooling is 05.~1mm nose radius but you can still get a large bend radius out of it. A good rule of thumb is choose a V width on the bottom tool 8 times the material thickness ...
All insulating fire bricks are aluminosilicate and so are hell on your lungs. Built a few kilns and furnaces over the years, and the msds documentation has never changed. Wear a respirator or wear the consequences
respectfully, he likely doesn't have the 5+ decades left to it would take for silicosis to do him in. also, this was a very small exposure. furthermore, if you start reading the fine print for yourself, you'll find that no respirators are actually rated for silica dust- ventilation is the only way.
@@travismiller5548 other people who are watching and could copy may have the time for silicosis. And if course there are filters that stop silica dust.
Unbelievable. You can make anything. I know you could have bought a heat treat oven but making it, taught you so much and we got a video out of it. Thank you so much and keep up the good work.
The "Sir!" was like one of the biggest compliments you can recieve, in a DIYing couple. I loved her muffled laughter at "I'm gonna a very safe thing here" right after introducing the limit switch.

@@projectbrewsky2048Hmmm. His wife is professional media person, and has edited every video on this channel. Its not like he calls wifey to come from kitchen to look what he has done in shop. They just dont use freehand camera. Its tool to make shots look intimate, like he is doing it alone. She might not be there planning every camera view, setting up cameras and doing videography. But for vast majority she is there in the shop doing all that. The fact that in most videos she dont talk means nothing. Taking nothing away from them, the duo produce entertaining content. Its showbizz and nothing wrong with that.
Just look at camera views, how well planned they are, how much they vary. One person making stuff at steady pace just cant wing such good quality camera work, its physically impossible. It takes more time to set up cameras to new shots in these videos than doing the actual work. Compare shots to for example Topper Machine. He is actually doing commercial work, and doing all alone his camera work plus editing.
@@kimj2570 Hey there! I don't disagree with most of what you said. His wife even said on a few videos that she's the one who edits his videos. She probably helps a lot with the camera work, lighting, etc. (although I doubt she's there every time he's in the shop making something. Clickspring can make stunning videos with impeccable camera work, and I believe he does it alone.) I'm just confused about the point you're making here, in your reply. All that commenter said was that it's awesome to have someone who truly supports you in the things you're passionate about, and I tend to agree, and whether she's always behind the camera or not, doesn't mean he's wrong. Are you suggesting the reactions and her compliments are somehow scripted, or exaggerated for a certain effect? I may have completely misunderstood your point, if that's the case, I sincerely apologize. Your comments aren't wrong, as far as I know. I just wonder what you're meaning to say here? Cheers!
As a hobby bladesmith I built an oven to do exotic alloys. 8000 watts and overbuilt. It has an industrial vibe to it but it definitely was cheaper than buying. I feel the tradeoff to building and buying is purely aesthetics. If I were to do it again and I had the budget to buy one I would build one a large touch screen controller like Evenheat or Paragon use from SDS industries. Quick note for anyone reading this, do not skimp on your SSR purchase. Cheap doesn't mean good and if you are pulling a lot of current they will burn up. Spend the extra cash and buy a quality relay.
I have built my share of kilns. The bricks have split as there probably was too much water in them. Normally you soak the bricks before using the mortar. The heat the oven below 100C for a few hours to get the moisture out. The split bricks won’t hurt the performance of the kiln. Sanding and cutting the fire bricks is super unhealthy without a mask. There is I believe, silica in it which never breaks down in your lungs. Stay safe, or I have to miss your great content.
You are the man, I am a retired Tool And Diemaker/Machinist/Gagemaker and I cannot even begin to have matched your all round skills, but as a Tool And Diemaker Apprentice, then Full on, I so appreciate do it old school sometimes, roughing out windows then filling to size with great large file!!!
A beautiful build overall but I’d have to say the door is my favorite component. Just add ceramic coffee cup holders on top and you’re ready for winter!
Gotta say that quite apart from enjoying the extreme craftsmanship shown in your videos, the recent ones featuring lovely interactions with your wife are very nice on a different level. My (ex) wife was never really supportive of my various interests, and felt quite strongly that a "mature" husband wouldn't *have* any interests other than supporting his family. Which always filled me with so much WTF? It's heartening to see an entirely different dynamic on your channel. Looking forward to more!
@@theKashConnoisseur Thanks. My current relationship is much healthier! She's very much in support of my current "little project", which is the restoration of a former-NATO satellite ground terminal for science education.
Sounds a lot like my (current) wife. At some point I just gave up even trying to share what I was working on, because you can only be disappointed so many times.
My GF literally just texted me: "Steel, steel!!!" She works in branding, self-admittedly she isn't techy. I am a photojournalist but I have found that a tinkerer lives inside me and he is prototyping a new product for freedivers. And these days, my split personality is deep into getting to know a little CNC router and just today I found out, I could cut tool steel on it, too. I was stoked, so I sent my GF a short video. And she was as happy as me:).
That is a beast of a heat treat oven, well made that man.. and yes the door mechanism is very impressive I must admit I would have sent the press break back by now.... I like that you are both interacting in your videos now....Thanks for sharing, its a good one
Dude! I love your channel! One of the many things I love about it is how awesome your wife is. It’s obvious that she knows when something is impressive because of her understanding of what you had to do to make/fix things. Anyway, love the channel, love the supportive wife, keep the videos coming!!!
I cannot stress enough how excited I get every time I open UA-cam and you have uploaded a new video. (Generally) very calming, and love seeing your processes
As always, you demonstrate human ingenuity and perseverance. From my memory, the cracking you observed in the refractory brick is a common occurrence and reflects the steam you observed leaving the kiln (from the bricks).
I love that this entire vid is just a side project to the lead screw. Keep 'em coming, you guys rock and we'll watch and thoroughly enjoy every step. Cheers.
Watching the wrapping of that wire with a power drill and 2x4 was so incredibly satisfying. I always learn something from watching your videos, but this time you've got the audience rapt.
I'm sorry but I think the best part about this video is just how excited she is for you. Like, I can hear just how happy she is and watch you light up as you hear that happiness.
Irony…a video about making an oven for heat treating metal to keep it from deforming/ cracking, proceeds to crack the aluminum for the oven while attempting to bend it because it wasn’t heat treated… Seriously, in case you’re unaware, if you anneal the aluminum along the bend line it will bend easily without cracking. I use the flame soot method. Hold a candle or any “dirty” flame under the aluminum and allow the soot to deposit along the bend line. Then use a torch (small propane is fine) and apply heat until the soot disappears. That will bring the aluminum to the annealed state. Bendy, no brakey👍🏻
If the rollers on the slip are thin wall tube you MIGHT be able to upgrade it with thicker wall tubes or solid bar to make the damn thing bend more consistently from edge to middle... The other way is to cut your shell in half lengthwise so that you are only bending half the length at a time.... I had to do this for the diamond plate I used for the custom service bed I made for my 1 ton pickup..... I made an 8' long bending break out of some really heavy scrap iron I had, but the reality is... I had to cut the diamond plate in half to reduce the force required to make the bends and then weld the two halves back together...
I think I like this kind of video style. It's far more casual, very few pre-written scripts, and the addition of your wife in the background is lovely. Love this vid.
I went searching to find the first BBW joke. Thought for a second I'd have to be the one to bring it up. Glad you were the one to make the awkward joke rather than me.
5:36 What a cool multimeter! In my teens, I traded entering Ham Radio antenna design programs into a TRS-80 for on of those meters at my local Radio Shack.
Very nice job, I have seen literally hundreds of different kilm builds, and I have built a few myself.. I say, the one you built is quite nice.. I by trade am a retired master carpenter, but got bored so I dabble with some knife making, some tools (screwdriver, chisel and such), pottery, other weird things, I make paracord stuff & I turned a deep freezer into a keezer (Kegerator) LOL.. I am very impressed with the many things my wife & I have watched you make and things you attempted.. Thank you for sharing and keep on creating..
This has to be my favorite project of yours thus far. I love seeing a complete doohicky being built out of bits and pieces, seeing things work out, seeing things not work out quite as much, figuring those things out so they DO work out, and ending up with a new piece of equipment that you can look at and take some serious pride in. It really all came together spectacularly, it was worth the longer than usual wait for the video upload.
I have that same combo Shear/Brake/Roll! It's been great for forming toolbox drawers and HVAC ductwork out of 28ga galvanized steel. I haven't tried it with thicker material but you're right - it's really rated for light duty stuff.
I swear like 3 or 4 videos ago your style was completely different. Either way your videos are always something fun to come back to. So just keep it up!
I love the design! I'm currently in the process of digging up information for my build, and so far, I've figured out that "gluing" bricks together can lead to cracking due to significant thermal expansion during heating and cooling cycles, just like you figured out. Most builders overcome this issue with layered construction: bricks on the inside (using mortar only when unavoidable), followed by kaowool to act as a buffer and provide tension to keep the bricks together, with a final outer layer made of calcium silicate boards. I did not figure out your wiring, so I may be mistaken, but it's preferable to have the end switch operating an individual relay/contactor that supplies the SSR. This is important because SSRs can fail open, potentially delivering mains voltage to the Kanthal coils. By the way, most PIDs can handle S-type thermocouples, which are more durable compared to K-type thermocouples. Regardless, it will definitely serve its purpose for decades-unless, of course, you burn out the coils. Great job! :)
You did a nice job, the challenges you overcome, tough when all you have is your own experience and UA-cam to guide you. The synergy of a few people can make a big difference. I do like your project and thanks for sharing. I will be purchasing my heat treat oven, but the lessons and education you bought is priceless. Cheers!
This is one of the coolest things I've ever seen. And the fact that you managed to do all this without having to weld is awesome to. I love your videos man.
You might consider adding the ability to flow nitrogen or argon into the furnace so that you can heat treat under a protective atmosphere and avoid decarburization.
@@jlsbeek that works too, but if you’re heat treating small parts out of non-air hardening steel it can be very difficult to get them out of the stainless foil and quench them before they cool too much. It can also insulate air hardening parts too much, depending on the alloy.
@@ryanvandyke2675put small parts in crucible with borax. Molten borax protects from decarburization. Then you just cast hot parts with borax into water. I saw it on Clickspring channel.
I don't trust in argon flow. I had previous experience with argon flow through tube in tube furnace and in spite of that my sensitive chemicals oxidized a bit. Diffusion is nasty for sensitive things. As a conclusion, if you really need totally inert atmosphere, your kiln must be completely sealed, possibly even vacuum is needed before letting argon in. All of that sounds like complicated specialized project, say for titanium alloys. Or commertial kiln inside glovebox with protective atmosphere.
@@ІгорАлієв atmospheric gasses can be difficult to deal with… I know folks who have entire careers around troubleshooting them in commercial settings. You’re right in that you’ll pretty much never get rid of oxygen in the furnace. At my work we have vacuum furnaces that pump down to less than 10^(-4) torr and maintain that partial pressure with argon… and parts made from Ti and some nickel alloys still have to have every surface 100% machined off to remove any material that might have interacted with oxygen while at heat. All that being said, if your goal is to simply heat alloy and tool steels up to their austenitizing temperature for a relatively short amount of time and avoid gross decarburization, then an argon inlet with a bit of positive pressure inside the furnace is completely adequate 😊
I like everything about your videos. Your attention to detail, the mistakes you make (because I can relate to the learning curve), and your presentation. Awesome work Bud!
I enjoy the interactions between you and your wife. You seem to have a fun and healthy relationship, which is a nice change from the toxic dumpster fires that modern media likes to highlight.
Very nice build. Those cracks that formed might be due to moisture. its important to slowly bake the bricks. If i replace the bricks in mine i run it at 50 celcius for about 5 hours with the door cracked open. After 5 hours i ramp it up to 150 celcius for another hour and then its ready to go full blast. I built my heat treating oven with the regular square design. Sent the cad drawings off for all the sheetmetal and had it laser cut and bend.😆 Still have nightmares about trying to bond all the bricks with mortar together outside of the shell in the end i just built the bricks up inside the shell. Had to replace the bricks a couple of times already so glad i went with an easy design. Using mine for heat treating knives so alot of different temperature cycles that do decrease the brick lifecycle.
Never think that if you bought it premade you will sail through with out a problem. The fact that you go through the process of making and building it from scrach is the most rewarding thing i have come to appreciate about the videos and projects you have done so far. I am invested in the way you do things and am looking forward to you competing the metal screw drive shaft.
Great video. A book I would recommend, "Heat Treatment, Selection, and Application of Tool Steels." By William Bryson. We use this to set up our Heat Treatment processes.
I have to say I did wonder where the next video was since it had taken so long but MAN was this good. I'd love to make projects of this scale one day and making my own oven like this would be so god damn fun
Im not a machinist, but I do enjoy your work. So much so that i have checked every friday for the last 4 weeks to see what you build next. For continent that engages the mind, youtube is the best, and your work and narration are great! Keep up the good work!
One of my favorite things about your videos is all the delightful interactions with your wife! Also, she's an awesome editor! I loved your solution to get the narration for this video by telling the story of the build to your wife, with us in the third chair. Keep up the great work you two!

Yeah the orbital sander on fire brick scene, with no respirator, had me sweating. This is my first video on this guy's channel, and I already love his work, but this was the most serious safety issue I've seen in a DIY/maker video in a long time...
YESS!!!! Safety when it comes to powder concentrations in the air is really important!
@@cmshap hes an engineer btw
@@watcheater9229 I'm not really sure how that's relevant. I'm not an engineer, and yet I always make a point to research anything I'm working with on a DIY project before hacking into it with power tools. And in fact, that's how I came to know that the primary ingredients in refractory bricks are alumina and silica, neither of which you want inside your lungs.
The amount of support your Ms. provides, even in setbacks, are astonishing. No matter how many tools you add, she's still the best resource you have in that shop.
Helps that she's also qualified, so it's not like he's trying to explain neurosurgery.
Good build. At the risk of repeating other comments a couple of suggestions for when you build the bigger one (you know you will need one). Use powder air-set refractory mortar rather than premix to save money. First use, heat up slowly, step to 110C and hold for about 4 hours to eliminate moisture, then ramp at 50C per hour to about 800C. Bricks expand and could stress the metal case, wrap the IFB with a layer or two of ceramic fibre paper to form a compressible spacer, this will also increase insulation and reduce the case temperature. Tune the controller yourself manually, auto_tune rarely gives the best results, there are plenty of good tutorials online, a lot of cheap controllers have variations on gain scheduling which can help with quick heat ups..
All this!
Excellent advice.
Great advice, I indeed thought that moisture should ve evicted slowly. Maybe additionally measure the humidity in the shop, then you can better estimate the duration of the warmup cycle. Loved to see all the work that went into it, gorgeous (bit tight) door mechanism!
That controller isnt the $30 Blamazon controller. The auto tune works brilliantly.
Novus is decent, but autotune never as good as a custom tune @chrisj4570g
Great finished product! For everyone else, who might build one-- bring the temperature up slowly to 95⁰C and hold there to allow most of the moisture to evaporate, then move to 105⁰ for about an hour to finish drying the firebricks. This will greatly reduce the fine cracks that you found in your's after your first use. Remember, water expands almost 1000 times in volume in its change from liquid to steam, so a small amount of water turned into a whole lot of steam and it had to find a place to get out. Failing to find a way out, the steam just made one!
Glad you wrote this. I was thinking the same thing.) 👍
I was about to write the same thing!
Maybe even better is to gradually rise until 800°C in like a day or so. There is a gradient of temperature in the bricks, so you might have dried the interior of the over but the core of the bricks is still moist if you only go to 105°C.
"Failing to find a way out, the steam just made one"
Just like ice... Either it has enough space to expand, or it will make some. Regardless of how much you like that water bottle..... 😢
she sounds like more fun all the time
Making the heating element was SO SATISFYING

The enthusiasm your wife shares for your projects is breathtakingly supportive.
Ya, the level of support is amazing. I bet it feels pretty good to have such a supportive wife
"Is this just a scope-creep or was the scope stupid from the beginning" is what I'm being asked by my manager whenever I'm presenting a new device I've designed at work. I'm going to make a banner out of it and hang it over my seat at work.
Hats off for a complex project very well done and thanks for sharing!
It might be categorized as Gold-Plated Scope Creep. Which means it won't rust, I presume.
I've been there, needed or wanted something, decided to build it. Days, weeks later I finished, was proud of what I made and how I made it, functioned exactly how I planned, but realized how much money I spent on it, hours put in, when I could have bought one for half the price. However years later it still functions same as it did on day one. Never know what you are buying, how long it'll last. Great work, looks great, works like you wanted, and you built it.
And if it does break, you know how to fix it, and the parts are off the shelf or equivalent.
HELL YEAH INHERITANCE UPLOAD
No other channel in this side of youtube is able to combine the quality of work, video production, charm and personality, and storytelling that you TWO manage with every single video. Brilliant stuff.
Former HVAC fabricator, for tight curves like you wanted we often used the press brake to make them. A series of small bends goes a long way
I have been tinning for 35 years. Long surface area's with small machines/equipment generally don't work out well, material thickness and malleability of the materials make a big difference as well. I was actually impressed that he was able to get it to turn out as well as he did, not meaning that to be negative.
I was waiting for an HVAC guy to try help with that sheetwork lol
And planish and burnish on a steel mandrel afterwards to smooth out the small ridges left by the brake (if you want to).
Or he could return the machine and build his own, better roller >:D
To achieve both high rigidity and ability to make small-ish corners you need to double the amount of rollers. A large diameter thick wall pipe pressing on a smaller cylinder that then acts on the sheet metal. This way the actual "tool edge" is supported along it's entire length and won't bow, allowing for more consistent bends.
I'm intrigued to know your process of developing a project like this. I normally do 10 designs in CAD before making 3 very fast and cheaply made prototypes before settling on my final quality design. You look like you just went for it and aimed for perfection from the start. Cheers J
Man, where's your PPE!? We're going to end up calling you Inheritance Silicosis after this...
These bricks will shatter when thermally shocked hard like that, straight from cold and moist. Not a big deal if the frame holds it together.
You might also want to run an auto-tune on the controller, to get it going up to temp faster and have it be more stable there. Run the autotune at approximately the median temperature you expect the oven to heat to most of the time.
That's exactly what I was thinking. A mask is a good idea any time you use a sander, but firebrick dust is a lot nastier than sawdust
maybe he didnt know! i def didnt so thank you for this comment
Yeah, I am like that dust is never coming out of his lungs now. Hopefully he was not exposed to it for too long. If you are working with dust get a respirator on, hell a dust mask will be better than rawdogging that silica dust.
fully agree, that stuff is nasty! get that proper ppe on there!
My inner QA/safety brain was screaming at the dust. I even use an N95 while doing simple wood routing, much less when I was repairing my chimney.
The next big shop project should honestly be a vent system (smoking hot metal and micro particulate is its own serious issue) and easy reach PPE storage.
I fully understand how annoying that is with a full beard (I've given up trying to shave myself clean given an five o'clock shadow about 7 hours too early), but organ damage in both short and long term is absolutely terrifying. I've read enough clinical horror stories on metal neurotoxicity to know not to screw with it.
The interview style format with your good lady along with the 'this is a bit out of my ballpark' but then achieving it is awesome dude. The comment on how your thing is mechanisms and then you speed montage through the mechanisms without narration bit was a nice touch! although you did miss the chance early on (7:55) to use the rotary to cut the radius in the bricks, and filling the rotary with silicone dust would have guaranteed the next project has at least 1 side project 'service the giver of pretty chamfers' lol. Look forward to seeing the oven in action!
Having spent a decade in heat treating and aerospace sheet-metal, I can write this say: outstanding job!
Suggestions:
1) When you are bending, bend with the grain set diagonally or perpendicular to the direction of the bend.
2) some light sanding at the edges of your bend axis will reduce likelihood of cracks propagating from the edges.
3) I guess you bought 2024-T 42 sheet metal for the shell. I don’t remember guidelines on bend radius ratio. But I think it is radius must be at least 2x the thickness when bending in the T42 condition. It may be 3X though.
4) your shell might warp overtime and make door ceiling difficult. A very simple titanium mesh, or braided fiberglass rope will make an excellent door seal.
5) Oven controls: you should have completely separate pyrometers for the monitoring and controlling the set point. Especially if you use K type thermocouples. Probably will not be such a problem if you use N type thermocouples. 5) Warning on K type thermocouples: don’t use them! They have terrible drift above 500 degrees Fahrenheit due to the electro mechanical properties
K type is fine, they are industry standard for a reason.
@@Ammoniummetavanadatesomething being a standard doesn't say anything about how good a fit it is for a specific use case. Type K thermocouples have plenty of uses, but they are not a particularly great choice for this situation, as this oven will be operating at temperatures high enough to cause permanent drift, which leads to lower temperature readings over time.
I'm sure that a type K would work just fine in this situation, because as a hobbyist the tolerances are large, and volumes are low. Typical lifetime drift for type K MIMS thermocouples is on the order of 20 degrees F. In an industrial setting, this does matter, but in a home hobbyist shop, it's much less of a concern.
Still, it certainly wouldn't hurt to use the better option if it's available and not significantly more expensive.
@@Bobbias I use hundreds of type K thermocouples daily in industry.
Also a lot of type B, J, and rtds for cryo.
Tolerance of type K is at best 0.4% so at 800C or 3.2C and more realistically is 0.75% which is 6C.
Type N TCs have roughly the same tolerance at 800C.
Your type N will also need to be calibrated and cross checked.
If he was operating in a reducing or vacuum environment sure the type N is a bit better but type K is totally fine for this oven.
If you are seriously concerned about getting an accurate temperature you employ multimeter dissimilar measurement devices.
I personally have a very very sensitive type R thermocouple that is heavily shielded and connected to an extremely precise amplifier that I cross check my other TCs with as well as a triple point calibration system I built for bench calibration.
In short type K is fine, always cross-check your instruments.
@@Ammoniummetavanadate I assume you meant to say "multiple dissimilar measurement devices"? Good option if practical.
Type R (costs a bit more) is more linear & stable -> more accurate, but technically is less sensitive in terms of uV/°C, not that it matters if you use a good indicator.
@marshallwilliams4054 For amateur workshop fabrication use this probe will probably be fine, it doesn't need to meet some aero alloy HT spec, would have been nice to add an overtemp cutout though.
@Ammoniummetavanadate type K is industry standard because it's cheap.

Once again, your timing was impeccable. To say this had been a crappy week at work would be to damn it with faint praise. And just when I needed to see a fun project done by fun people, you delivered. Thank you.
I ran into the same problem trying to bend some thin (3/16") 6061-T6. The solution is to anneal it; but how? Basically mark where you want your bend, and then paint a 1" wide stripe of brand name black Sharpie marker along that line. Hit the other side of the aluminum with a MAPP torch, playing the flame back and forth along the back side of the line. At some point, the band of Sharpie marker on the other side will begin to "evaporate" and turn from black to a translucent gray. This is the annealing point. Go much hotter and aluminum will begin to pucker or melt. Do this the same day as you plan to make your bend, as some alloys can "precipitation harden" over time and undo your annealing. It worked beautifully for me; no cracks, no splits, just nice smooth bends. Thanks for an amazing video. That was a beautiful build. Oh and making that coil with the drill and jig? Absolute nerdgasm over here.
Yeah, I was thinking the same thing. Didn't know about the sharpie trick though, thanks for that tip.
Soot from an acetylene torch works as well. Just coat the area you want to anneal in soot and heat till the soot dissappears. It's slightly faster to apply then the sharpie method.
Read this two seconds after I posted. You are right on. I worked 46 years in a series of different positions. Every piece of metal takes a different procedure.
wow that's impressive! The bricks cracked because of moisture trapped inside them. That's why you have to ramp the temperature up slowly step by step to dry them. The kind of procedure we use on new pizza ovens. Biggest ones can take 2 days doing that
damn... too late now!
I don't think I've ever seen a used oven that didn't have cracked bricks. Just seems to go with the territory.
@@TEDodd thing is that every time it's not used for a while it traps moisture again. Unavoidable in the end

Hello, my name is Inigo Montoya 14:34
I'm a retired electrician, just starting out in the machining hobby, so that electronics enclosure was ridiculously satisfying , well done.
You dont realize how happy i was when i saw you finally uploaded again. I recently discovered your channel and watched all of your videos( yes. all). Thanks mate
"What if you need to heat treat something wider than that?"
"You don't"
🤣
Seriously though that was an awesome build. Your videos are the ones I'm most excited to watch. I learn something that I might be able to use (various techniques you use) and get to see cool builds come together in the most satisfying way
Makes sense though. The larger you make the inside, the more energy it takes to heat up and maintain that heat. You build your heat treat ovens just big enough for the objects you plan on heat treating, no bigger.
You rotate it slightly and make some more brick dust?
The knowledge you got from making this oven is priceless. It's worth more than the money you need to just buy one. And in the comment section you learned the hazardous dust of the oven bricks and they break up due to the heat cycles.
I'm an engineer for a company who makes sheet metal enclosures. So, its funny to see what problems you run into, looks very good though! For next time: to bend the large radius this is best done on the (bend) press. Eighter make a series of small bends close together, like 10x9 degrees, or make a bend tool with the desired radius instead of the V shape.
I was thinking make a pipe w the radius bend and put that in the press
Also the cracking looks really familiar to using 6061 instead of 5052.
really love that your wife is keeping you company all the way through, and enjoying it! as a fabricator, I'd go insane without a couple people in the shop to keep me company.
This video is like watching an interview of myself doing the same thing, but over 2 years! Between using my drill press as a brick router, 5 failed attempts at making proper coils, replacing crappy/rekt thermocouples, burning out a couple relays, etc. It was by far my most problematic build so far. doing the calculations for W/cm3 had me feeling like a scientist. Now my oven gets to 1100C in 15 min, and ive heat treated dozens of knives precisely. Watching this video was cathartic. knowing someone else has been through what I've been through. Well played, and enjoy!
That oven looks CLEAN!!!!! Even when it was just the sanded bricks it looked nice. Great work!
25:56 is the most gorgeous bell tolling sound, it's like a heavenly being sent you a notification that your die was too sharp
Pro bending tip! The sharp tool did't help, but .. the bed radius was still too tight. The bend radius is determined by the width of the V not the sharpnedd of the tool. Most tooling is 05.~1mm nose radius but you can still get a large bend radius out of it. A good rule of thumb is choose a V width on the bottom tool 8 times the material thickness ...
He's back!
Please wear a respirator when working with fire bricks. You can get Silicosis from the dust.
I was watching thinking surely the dust from those can't be safe, but had no idea.
Hope he wore it for the bandsaw at least!
Depends on what the bricks are made off, but yes; better to be safe.
All insulating fire bricks are aluminosilicate and so are hell on your lungs. Built a few kilns and furnaces over the years, and the msds documentation has never changed. Wear a respirator or wear the consequences
respectfully, he likely doesn't have the 5+ decades left to it would take for silicosis to do him in. also, this was a very small exposure. furthermore, if you start reading the fine print for yourself, you'll find that no respirators are actually rated for silica dust- ventilation is the only way.
@@travismiller5548 other people who are watching and could copy may have the time for silicosis.

@@projectbrewsky2048Hmmm. His wife is professional media person, and has edited every video on this channel. Its not like he calls wifey to come from kitchen to look what he has done in shop. They just dont use freehand camera. Its tool to make shots look intimate, like he is doing it alone. She might not be there planning every camera view, setting up cameras and doing videography. But for vast majority she is there in the shop doing all that. The fact that in most videos she dont talk means nothing. Taking nothing away from them, the duo produce entertaining content. Its showbizz and nothing wrong with that.
Just look at camera views, how well planned they are, how much they vary. One person making stuff at steady pace just cant wing such good quality camera work, its physically impossible. It takes more time to set up cameras to new shots in these videos than doing the actual work. Compare shots to for example Topper Machine. He is actually doing commercial work, and doing all alone his camera work plus editing.
@@kimj2570 Hey there! I don't disagree with most of what you said. His wife even said on a few videos that she's the one who edits his videos. She probably helps a lot with the camera work, lighting, etc. (although I doubt she's there every time he's in the shop making something. Clickspring can make stunning videos with impeccable camera work, and I believe he does it alone.)
I'm just confused about the point you're making here, in your reply. All that commenter said was that it's awesome to have someone who truly supports you in the things you're passionate about, and I tend to agree, and whether she's always behind the camera or not, doesn't mean he's wrong.
Are you suggesting the reactions and her compliments are somehow scripted, or exaggerated for a certain effect?
I may have completely misunderstood your point, if that's the case, I sincerely apologize. Your comments aren't wrong, as far as I know. I just wonder what you're meaning to say here?

Thank you . I've been researching building a forge for a year now. This is the best video I've seen
❤❤❤❤❤❤
As a hobby bladesmith I built an oven to do exotic alloys. 8000 watts and overbuilt. It has an industrial vibe to it but it definitely was cheaper than buying. I feel the tradeoff to building and buying is purely aesthetics. If I were to do it again and I had the budget to buy one I would build one a large touch screen controller like Evenheat or Paragon use from SDS industries. Quick note for anyone reading this, do not skimp on your SSR purchase. Cheap doesn't mean good and if you are pulling a lot of current they will burn up. Spend the extra cash and buy a quality relay.
I LOVE the more informal interview style with your wife. Super happy that you've put more personality into your videos.
I have built my share of kilns.
The bricks have split as there probably was too much water in them. Normally you soak the bricks before using the mortar. The heat the oven below 100C for a few hours to get the moisture out.
The split bricks won’t hurt the performance of the kiln.
Sanding and cutting the fire bricks is super unhealthy without a mask. There is I believe, silica in it which never breaks down in your lungs. Stay safe, or I have to miss your great content.
Everytime I watch i know im gonna be entertained by a video that is not only informative but also well produced. Thatnks for another one

Gotta say that quite apart from enjoying the extreme craftsmanship shown in your videos, the recent ones featuring lovely interactions with your wife are very nice on a different level. My (ex) wife was never really supportive of my various interests, and felt quite strongly that a "mature" husband wouldn't *have* any interests other than supporting his family.

She works in branding, self-admittedly she isn't techy. I am a photojournalist but I have found that a tinkerer lives inside me and he is prototyping a new product for freedivers.

Irony…a video about making an oven for heat treating metal to keep it from deforming/ cracking, proceeds to crack the aluminum for the oven while attempting to bend it because it wasn’t heat treated…
Seriously, in case you’re unaware, if you anneal the aluminum along the bend line it will bend easily without cracking. I use the flame soot method. Hold a candle or any “dirty” flame under the aluminum and allow the soot to deposit along the bend line. Then use a torch (small propane is fine) and apply heat until the soot disappears. That will bring the aluminum to the annealed state. Bendy, no brakey👍🏻
Now this is some of the most serious dedication and skill utilization (not to mention the frustration) I've seen towards a project, great job.
The spiced in interview bits are really a good addition to the format. Great video as always.
Splendid! Thank you that was fun to watch and thank you to the misses also.
For a metal break, check out Colin Furze’s shop tour. In it he shows a simple and cheap home made break.
If the rollers on the slip are thin wall tube you MIGHT be able to upgrade it with thicker wall tubes or solid bar to make the damn thing bend more consistently from edge to middle...
The other way is to cut your shell in half lengthwise so that you are only bending half the length at a time.... I had to do this for the diamond plate I used for the custom service bed I made for my 1 ton pickup..... I made an 8' long bending break out of some really heavy scrap iron I had, but the reality is... I had to cut the diamond plate in half to reduce the force required to make the bends and then weld the two halves back together...
Dude this was insane. I watched Red Beard's video and thought THAT was a crazy build, you truly took his idea to the next level. I applaud you sir.
I think I like this kind of video style. It's far more casual, very few pre-written scripts, and the addition of your wife in the background is lovely. Love this vid.

This has to be my favorite project of yours thus far. I love seeing a complete doohicky being built out of bits and pieces, seeing things work out, seeing things not work out quite as much, figuring those things out so they DO work out, and ending up with a new piece of equipment that you can look at and take some serious pride in. It really all came together spectacularly, it was worth the longer than usual wait for the video upload.
As someone who spent 10 or more years in the Kiln/Oven manufacturing industry I have to say this is a very impressive build. Kudos.
14:14 you look like you would sell me some sort of elixir or tonic of questionable quality
Ha! For real!
I have that same combo Shear/Brake/Roll! It's been great for forming toolbox drawers and HVAC ductwork out of 28ga galvanized steel. I haven't tried it with thicker material but you're right - it's really rated for light duty stuff.
I literally said out loud "He's gonna have a better rivet gun by the end of this". Lo and behold 😂 Great vid as ever!
I swear like 3 or 4 videos ago your style was completely different. Either way your videos are always something fun to come back to. So just keep it up!
You Sir have once again out done yourself. Damn that oven is badass! Thanks for bringing us along.
I love the design! I'm currently in the process of digging up information for my build, and so far, I've figured out that "gluing" bricks together can lead to cracking due to significant thermal expansion during heating and cooling cycles, just like you figured out. Most builders overcome this issue with layered construction: bricks on the inside (using mortar only when unavoidable), followed by kaowool to act as a buffer and provide tension to keep the bricks together, with a final outer layer made of calcium silicate boards. I did not figure out your wiring, so I may be mistaken, but it's preferable to have the end switch operating an individual relay/contactor that supplies the SSR. This is important because SSRs can fail open, potentially delivering mains voltage to the Kanthal coils. By the way, most PIDs can handle S-type thermocouples, which are more durable compared to K-type thermocouples. Regardless, it will definitely serve its purpose for decades-unless, of course, you burn out the coils. Great job! :)
I dropped the other video I was watching when this popped up. Love your content.

This is one of the coolest things I've ever seen. And the fact that you managed to do all this without having to weld is awesome to. I love your videos man.
You might consider adding the ability to flow nitrogen or argon into the furnace so that you can heat treat under a protective atmosphere and avoid decarburization.
Wrap your part in a stainless steel foil with a piece of paper inside. The paper burns off oxygen.
@@jlsbeek that works too, but if you’re heat treating small parts out of non-air hardening steel it can be very difficult to get them out of the stainless foil and quench them before they cool too much. It can also insulate air hardening parts too much, depending on the alloy.
@@ryanvandyke2675put small parts in crucible with borax. Molten borax protects from decarburization. Then you just cast hot parts with borax into water. I saw it on Clickspring channel.
I don't trust in argon flow. I had previous experience with argon flow through tube in tube furnace and in spite of that my sensitive chemicals oxidized a bit. Diffusion is nasty for sensitive things.
As a conclusion, if you really need totally inert atmosphere, your kiln must be completely sealed, possibly even vacuum is needed before letting argon in.
All of that sounds like complicated specialized project, say for titanium alloys.
Or commertial kiln inside glovebox with protective atmosphere.
@@ІгорАлієв atmospheric gasses can be difficult to deal with… I know folks who have entire careers around troubleshooting them in commercial settings.
You’re right in that you’ll pretty much never get rid of oxygen in the furnace. At my work we have vacuum furnaces that pump down to less than 10^(-4) torr and maintain that partial pressure with argon… and parts made from Ti and some nickel alloys still have to have every surface 100% machined off to remove any material that might have interacted with oxygen while at heat.
All that being said, if your goal is to simply heat alloy and tool steels up to their austenitizing temperature for a relatively short amount of time and avoid gross decarburization, then an argon inlet with a bit of positive pressure inside the furnace is completely adequate 😊
I like everything about your videos. Your attention to detail, the mistakes you make (because I can relate to the learning curve), and your presentation. Awesome work Bud!
I enjoy the interactions between you and your wife. You seem to have a fun and healthy relationship, which is a nice change from the toxic dumpster fires that modern media likes to highlight.
it's rare to see such impressive craftsmanship on youtube... i really enjoyed to watch it and even learned some new tricks ... awesome!
Very nice build.
Those cracks that formed might be due to moisture.
its important to slowly bake the bricks.
If i replace the bricks in mine i run it at 50 celcius for about 5 hours with the door cracked open.
After 5 hours i ramp it up to 150 celcius for another hour and then its ready to go full blast.
I built my heat treating oven with the regular square design.
Sent the cad drawings off for all the sheetmetal and had it laser cut and bend.😆
Still have nightmares about trying to bond all the bricks with mortar together outside of the shell
in the end i just built the bricks up inside the shell.
Had to replace the bricks a couple of times already so glad i went with an easy design.
Using mine for heat treating knives so alot of different temperature cycles that do decrease the brick lifecycle.
I love the banter between you two.
Loved this style of video man, the back and forth was great!! And obviously, you did an amazing job on this project brother!!
Never think that if you bought it premade you will sail through with out a problem. The fact that you go through the process of making and building it from scrach is the most rewarding thing i have come to appreciate about the videos and projects you have done so far. I am invested in the way you do things and am looking forward to you competing the metal screw drive shaft.
I've been waiting for inheritance video for like a month ❤
Hi Brandon. Glad your back. The oven
Is really nice. Lots of work, but your skill showed again. Looking forward to more videos. Be Well. Cheers. David
Great video.
A book I would recommend,
"Heat Treatment, Selection, and Application of Tool Steels." By William Bryson.
We use this to set up our Heat Treatment processes.
I have to say I did wonder where the next video was since it had taken so long but MAN was this good. I'd love to make projects of this scale one day and making my own oven like this would be so god damn fun
OMG I have that Radio Shack multimeter, I was a Shack employee in the 80's & 90's
I miss radio shack
@@Onyex.- There’s still one In New Prague, MN if you’re ever in the area. It’s about an hour SW of the Mpls Airport.
Im not a machinist, but I do enjoy your work. So much so that i have checked every friday for the last 4 weeks to see what you build next. For continent that engages the mind, youtube is the best, and your work and narration are great! Keep up the good work!
One of my favorite things about your videos is all the delightful interactions with your wife! Also, she's an awesome editor! I loved your solution to get the narration for this video by telling the story of the build to your wife, with us in the third chair. Keep up the great work you two!
I am laughing out loud because I also have that same antique Micronta multimeter in my basement! I don’t use it often, but it still works after maybe 30 or 40 years!
