This was such an awesome gag to see. Reminds me of This Old Tony and Clickspring. One day i will start a channel in my own shop and hopefully get big enough to do a collaboration with IM.
The first time watching "not an engineer" made me subscribe to InheritanceMachining😂😂. Waiting for your video of this new element added to the box of shame.
I get it now. This channel is you building tools so you can build more tools. The tools aren't going to be doing anything more than upgrading themselves.
Not everyone who graduates with an engineering degree SHOULD be considered an engineer. You know more than most about machining, and machine design as well. Really enjoyed your video.
When I was watching the intro I was thinking "did I see Inheritance Machines box of shame or what the hell did I see?". Glad to be right. Lol'd when his cameo began.
Welp, now there are three cool channels that have made an appearance in this video, although I shouldn’t be surprised to see BPSspace watching this channel.
I think that's a modified earthworks M50, isn't it? I would think that's pretty clean, but agree that it might be a bit sterile-sounding. Maybe the mod will allow for some added low-end warmth.
I felt the first mention of "side project" as a foreshadowing. I'm glad I wasn't disappointed. I can't believe the box of shame has something with a complete lack of chamfers.
barefoot is a bit too much protection for my tastes, I like my wang out and about near the spindle, lead screws, and thread feed when machining, which of course disallows the use of pants.
Nude under a leather apron like "I did a thing" is the only way for an Aussie to do machining/fabrication imo (That one shot where he is dancing, barefoot and nude except for a leather apron, *on top of his lathe,* nearly gives me a heart attack)
According to some Bangladeshi casting and machining videos I’ve seen, Safety Sandals are absolutely the best way to go while working with hot and sharp pieces of metal.
Back when I decided to prove to myself that I still knew how to do CAD, I designed and 3d printed a cycloidal drive. I also designed and 3d printed a harmonic drive some months later. Good times.
To be fair no amount of patronage saves these places going out of business because of landlord greed. Meat markets and machine shops are insanely profitable, which is why landlords target them so hard. This creates a positive feedback loop with regard to average rent.
@@AndrossUT In this particular case, the owners passed away and the children inherited the property. With all the gentrification going on around here, they tripled the rent and instead of a machine shop we'll have a pet barn.
@@AndrossUT Landlords aren't charities, they also don't target anything. There is the value of the land and if the other guys are willing to pay more why should the landlord settle for less. I'd like to see you refuse a pay raise before you start asking others to do the same.
I love how, when you started this project you were like "I'm not confident this thing can cut a circle." and then at 18:24 you evolved to "f@&k it, if it can cut one circle, it can cut *TWO* circles"
For future iterations: such high precision circular patterns should be made by indexing the workpiece with dividing head while keeping mill XY locked. Mill will always have some backlash and XY mismatch as well as XY perpendicularity error. All of these together will create hot mess when absolute position and circularity are important.
I had the same thoughts - thats the real reason I mounted everything on the rotary table at the start. But then I thought - screw it, lets see how it goes.
@@NoEngineerHere also as you said in the video that coupler is flexing a lot and a stiff one I belive will drastically improve the flex. It is designed to flex to reduce stress from jerking movements but thats of course exactly what you dont need.
As an engineer, I absolutely loved your time-warp effect ❤❤ ...and also your creative use of translated lyrics subtitles between 18:00 and 20:00 was just genius! First casually building confidence, then sneaking in the message 😂😂 Thank you for an absolutely wonderful video!
To get you back you back for your boring bit crack. I watch a documentary last night on TV. It was about how the hulls of Super tankers are put together. It was riveting!
When I saw the bit about the box of shame, the parts being packed up and DHL I just about twigged before IM strolled into view. Definitely the right home for those parts. H'mm that gives me an idea ... I had parts jumping out the lathe spindle this weekend that I'm ashamed of ....
Cue the IM subsidiary "Recycled Shame". Motto "Ship your shame to the other side of the planet, where something good might come of it. When the bin's full."
The quality if your videos and everything you put out on your channel is legitimately insane. That doesn't even take into account the size and age of your channel, if you do take that into account, you're on a whole different level. Thank you for making awesome content, you rock!
Incredible machining, and incredible animations! This was really entertaining story telling, combined with some nicely timed humor. I can't wait for more!
As one who is a DE and uses CATIA, I think it's wonderful how you brought your ideas to life. You appear to be very resourceful and creative. The underscoring lesson here is to appreciate the importance of GD&T in your designs.
That was fun to watch. As a 1st yr elec apprentice with a supply authority we all spent 3 months in the engineering workshop, which I enjoyed, I loved to learn. In my 2nd,3rd & 4th years any behavior that was frowned upon meant more time in the workshop, So I spent a few stints there. I wasn't worried as loved, almost, every day there. Thanks for the vid.
FINALLY SOMEONE WHO SPEAKS IN HUNDREDTHS OF A MILLIMETER INSTEAD OF MILLIONTHS OF A FOOTBALL FIELD Also at 22:10 dude knew exactly what he was saying I don't believe in his innocence.
@yanikivanov Why? They are just as precise as each other. It makes sense he uses metric because he is Australian if he was American or Liberian or even British then why wouldn't you use the measurement system that makes the most sense to you?
I don't have the money nor the intelligence to do the things you do. I've turned wrenches on and off for 25 years. I enjoy discovering how things work even if I don't completely understand the details. I get literally giddy with excitement when you release a new video. Keep them coming! ❤
I used to service hoists with a cycloidal drive and it was a raging pain in the ass, it had something like 70 pins that needed to be removed, gauged, greased, replaced and reassembled but since the top plate was bolted to the top cover you had to lower it down without touching any of the pins (or you would knock them over) and I wore the edges off all the classic swear words and totally broke a few I invented just for that particular job. Cool project, thanks for reminding me of that particular slice of hell.
There is another type of cycloidal reduction box you can make that is easier to get backlash-free & easier to fabricate because all the critical machining is groove into planer disk surface. The engagement is axial, not radial. The "rollers" are ball bearings acting between 2 grooved disks. Because of the axial arrangement, backlash can be taken up to compensate for wear or fabrication. 2 facing disks have cycloidal track machined into them: one hypocycloidal, the other epicycloidal. Ball bearings roll between them, held under axial compression. 2 stacked assemblies are used to remove the orbital motion & the difference between the 2 ratios permits large ratios with low lobe counts. A central crank forces orbital motion (same as for drive you have).
@@Nedw Web search gets nothing (I tried "AXIAL cycloidal gearbox). The search latches on "cycloidal" & ignores "axial". I found about this in old optical catalog (for fine motion of optics without backlash). The benefit of this scheme is the ease of making if you have manual lathe & CNC milling machine. All of the "non-circular" elements are machined on a plane surface (simple cycloidal groove that ball bearings roll in). Calculating the CNC files is simple. It is the superposition of 2 circular motions: one is once around, & the other is multiple times around. One plate has path where the 2 rotations are the same direction (makes cycloid) & the other opposite rotations (makes hypocycloid). The (larger) radius of the once-around rotation & the (smaller) radius of the multiple-times around rotations are the same on the 2 mating surfaces. You need 3 plates (2 surfece-sets) total. The center plate is forced to orbit by eccentric. The ratio between plate 1 & plate 2 is different than that between 2 & 3 & in the opposite direction. For example, if ratio 1 is 15:1 & ratio 2 is 16:1 (reversed), the total ratio of 240:1. I do have CAD files of one I made experimentally. If you have place where I can send them, I offer them for you to look at.
I found a patent for an "axial cycloid reducer", then hit a dead end. I also came across magnetic cycloidal reducers, which are neat but have radial "engagement" not axial.
24:10 That is called an internal nut. Also, in some instances, it is called a 'gland' or 'gland nut' [mainly in hydraulic applications and maritime drive shaft applications, where some form of [usually lubricated] fluid seal and sliding, or rotating shaft is being held by the assembly.
A not-engineer sends the culmination of countless hours of work to an engineer. Engineer promptly stuffs said project into a box of shame. Despite the forewarning of the lathe crash, I still got a jolt of adrenaline when it hit. Love your work 👍
Mate the standard of your work for someone claiming to not be an engineer is nuts. You create some of the most precise things I've seen on UA-cam from any channel that's not a company or Clickspring, another Aussie, (is it something you drink?) but the 2 of you work at virtually opposite sides of the scale. The Inheritance Machining gag was top notch another thing your channel brings to the machinist space, a bit of fun not taking something, you obviously do very seriously, to seriously something until now I had to rely on This old Tony for. Thank you
@Turnipstalk so you don't watch inheritance Machining then? The bloke who runs that is exactly that an engineer who does top notch machinists work on his channel. Which a part of why the joke in this video. Oh and not sure why you felt the need to tell me this when my "for someone who claims to not be a engineer" is just a saying nothing more. I don't expect him to be both nor does it matter to the quality of his work.
@Turnipstalk sorry bro having a bad day at the time and reacted without really taking in your comment. Get so used to getting attacked on UA-cam by people being, well people who can say what they want without consequences that it was basically automatic.
Love the example of the lathe spinning out and stopping from your tool. First time seeing someone else show that so people understand the difficulty of using these haha
It is really, really hard to stop myself watching this video. I needed a break at 10:00 and struggled to avert the gaze until 24:00. I have finally done it and can make a cup of tea. What a content.
Man you really outdid yourself on this one! The cameo, your wife/girlfriend/whatever shouting wtf, the project, loved it! Became a patreon after having laughed for a few video's, worth it. :)
@@NoEngineerHereI am a Machinist, and I accidentally selected a feed lever the wrong way once it was .6mm/rev where I wanted .3mm/rev it was going at 400rpm and the 50kg chunk of metal was on a bit of a angle and stalled the lathe instantly I thinking just how bad might of been if it was not a small part in a small lathe
Around 1991 I was a young Elecromechanical Apprentis. I had been an Auto mechanic prior to working in the motor shop. I had a few worm gears, and several motors under my belt. My boss began freaking out, when he came in and saw 2 Cyclogears, completely dissassembled on my bench. Closest he ever came to screaming,, he yelled,, "We DON'T WORK ON CYCLOGEARS!! We Never have!" Not knowing,, I asked Why? Because you can't get them back together! Too complicated! He shouted! These were something in the 180 to 1. Ratio, multi stack. But low powered,, like 1.5hp used to extend/retract Gym Bleachers. He paced back and forth as I changed the bad bearings, and put them both back together. He calmed down, as we successfully test ran the first one. When he came back and saw the second one running fine, he said,, "Well I guess We work on Cyclogears."😊 dude you're good 👍! Cheers!
Between the ridiculous [not] engineering that went into this, the soldering iron mic, and the fact that you sent your first attempt all the way to IM for the box of shame...I'm subbing. First rate all the way. Well done, man.
So, I'm watching this man make a very complicated gearbox to remove backlash. But so far he hasn't mentioned why he NEEDS no backlash whatsoever. What application needs this design?
I can't think of one offhand for something at home, but I've run into them at work for speed compensation gearboxes in printing where any backlash results in huge changes in print or cut quality
As somebody who's also not an engineer (at least, not of the realm where ctrl + z doesn't work), there was a lot of this I didn't understand, but still found entertaining. Great stuff!
Man, I love your dry humor. Most will not get it unless they have ran into similar issues with projects. My muse is more along the lines of experimental electronic component builds(for example working on an experimental TEG that is entirely printable, it's very touchy. Junction points as small as 1 mil (mil as the measurement mil and not millimeters. Average human hair is 1 mil.) and up to 5 mil. Graphite, graphene, and conductive inks ranging from nickel to gold. Sensitive enough to use sun light to generate. I currently have to draw them out by hand for test models until I get the measurements within a working tolerance. Tedious does not even begin to describe it.), so even though I do not know many of the ins and outs of machining I certainly feel your pain. Keep it up, you are making great progress! Looking forward to further videos like this. You earned a subscriber.
I know jack about machining but this guy turned a topic I'm not partial to learn about, and managed to make it entertaining enough that I, a young, distractible adult with ADD, watched all 30min without looking away😅
Arrived here from IM and have just hoovered up every minute of content you've so far put out. I've not done that amount of back-to-back UA-cam onsessive watching within the same day since I discovered Bobby Fingers. You're killing it - and making me realise that I need to embrace the Dunning-Kruger effect a little more in my own workshop. Nice one. Charlotte
My favorite aspect of the video is how threatening you manage to look holding casually waving that soldering iron back and forth from a seated position; big Wilford Brimley energy
A little something I learned 50+ years ago in school, but have never used. If reamed holes are slightly to small, offset reamer axis slightly, and, no, I don't remember how slightly, to make the reamed hole a bit larger. I hope this actually works, as I have not personally used this technique in my over 50 years of machining. CNC has changed what can be easily machined so much. I have a really long story about helping with the set-up for one of these gearboxes, back in the old days, but it will have to keep til I cross seeing the Southern Cross off my bucket list and perhaps visit with you.
That was really really interesting. It makes sense of the various references I've heard to genetics in the past several years. Thank you for the explanation. Also I don't think it's boring at all. The fact that the works is more nuanced and subtle than before just gives us more to discover and use imho
Coolant is your friend, you can use a spray bottle. Or brush with oil. A few things, this type of drive system is going to be loud compared to constantly meshed spiral cut gears. Also the lash in the gears is there for a reason, as the parts are in use they heat up and expand. Having them too tight will make it very tight and create wear. Also the gap keeps oil flinging in between the teeth. The teeth are also hardened so i have not finished your video yet but i dont see any plans for heat treatment.
Another thing, you have no vent, this will create pressure as it warms up and cools, you need a vent in and gearcase or transmission or the seals will blow out.
Honestly for a hobbiest the finish and tolerancing on that machining is pretty darn impresive! I've only really seen better in a professional setting at work where we make aerospace parts. And even the guys on the shop floor don't get it right all the time either and we have to scrap more than you'd probably think.
17:44 Pro tip for unboxing large heavy things- 1. Flip box over so bottom is facing up. 2. Cut tape, and open up box. 3. Carefully roll opened box over so the bottom is facing down again. 4. Lift box off large heavy thing.

Though in Sydney "internal nut" is a sort of sexual misadventure that'll land you in St Vincent's for the weekend.
i knew ive seen that wooden box before.... nice cameo. now we need some woodworker to make him a new (and definitely bigger) box of shame,
I never understand why I am attracted to engineering problems that I will never have.
A not-engineer sends the culmination of countless hours of work to an engineer. Engineer promptly stuffs said project into a box of shame.
Despite the forewarning of the lathe crash, I still got a jolt of adrenaline when it hit.
Love your work 👍
Mate the standard of your work for someone claiming to not be an engineer is nuts. You create some of the most precise things I've seen on UA-cam from any channel that's not a company or Clickspring, another Aussie, (is it something you drink?) but the 2 of you work at virtually opposite sides of the scale. The Inheritance Machining gag was top notch another thing your channel brings to the machinist space, a bit of fun not taking something, you obviously do very seriously, to seriously something until now I had to rely on This old Tony for. Thank you
It’s gotta be the Vegemite…
@Turnipstalk so you don't watch inheritance Machining then? The bloke who runs that is exactly that an engineer who does top notch machinists work on his channel. Which a part of why the joke in this video. Oh and not sure why you felt the need to tell me this when my "for someone who claims to not be a engineer" is just a saying nothing more. I don't expect him to be both nor does it matter to the quality of his work.
@Turnipstalk sorry bro having a bad day at the time and reacted without really taking in your comment. Get so used to getting attacked on UA-cam by people being, well people who can say what they want without consequences that it was basically automatic.
ahh yess the casual cameo of one of my favorite machinists is top tier, also that lathe crash made my soul jump
Love the example of the lathe spinning out and stopping from your tool. First time seeing someone else show that so people understand the difficulty of using these haha
Dude you're getting into the realms of farmcraft101, TOT, old AvE and so on in my book. I get excited like a kid when you upload. Good jerb
If your audio was bad, I wouldn't be watching. You've learned the important lesson of having good audio. Bravo.
That handheld microphone paying for itself.
I hope the trend of makers sending Inheritance their scrapped parts catches on
I just watched inheritance machine and then came to him. The two are perfect for each other. I’ll now watch both.
It is really, really hard to stop myself watching this video. I needed a break at 10:00 and struggled to avert the gaze until 24:00. I have finally done it and can make a cup of tea. What a content.
It's even funnier when you realise he is holding a soldering iron which actually has no mic attached 😂. Love your content!
Man you really outdid yourself on this one! The cameo, your wife/girlfriend/whatever shouting wtf, the project, loved it! Became a patreon after having laughed for a few video's, worth it. :)
The soldering iron "mic" is a nice touch.
I was subconsciously waiting for him to suck on it like a hookah
OK, so this has been recommended for a few days. Damn, UA-cam does know me better than my mum. This is as good as it gets. You got a new subscriber.
okay, now THAT'S a solid sponsorship segment... literally went half of it without realizing I was still watching a sponsorship segment.
I really enjoy your sense of humor and talent.
That lathe clip in the intro
It lives rent free in my head
@@NoEngineerHereI am a Machinist, and I accidentally selected a feed lever the wrong way once it was .6mm/rev where I wanted .3mm/rev it was going at 400rpm and the 50kg chunk of metal was on a bit of a angle and stalled the lathe instantly I thinking just how bad might of been if it was not a small part in a small lathe
Around 1991 I was a young Elecromechanical Apprentis. I had been an Auto mechanic prior to working in the motor shop. I had a few worm gears, and several motors under my belt. My boss began freaking out, when he came in and saw 2 Cyclogears, completely dissassembled on my bench. Closest he ever came to screaming,, he yelled,, "We DON'T WORK ON CYCLOGEARS!! We Never have!" Not knowing,, I asked Why? Because you can't get them back together! Too complicated! He shouted!
These were something in the 180 to 1. Ratio, multi stack. But low powered,, like 1.5hp used to extend/retract Gym Bleachers. He paced back and forth as I changed the bad bearings, and put them both back together. He calmed down, as we successfully test ran the first one. When he came back and saw the second one running fine, he said,, "Well I guess We work on Cyclogears."😊 dude you're good 👍! Cheers!
Very cool :)
If this is a commercial, it is the best and perfect i ever saw. Ranked #2 after "Die Mutter aller Imagefilme" (the mother of all imageclips).
I've rebuilt a few of those cyclo drives at an old electric motor shop I worked at years ago. Love the video. a laugh around every cut scene.
Dude! You're married to Leeloo from Fifth Element!? Sweet! (also, cool project. loved the IM gag)
This is a final test, a true engineer would never ever think of doing a cycloidal reduction himself. Never, no chance.
What I need from a gearbox is some more alcohol. Love your vids 😊
Between the ridiculous [not] engineering that went into this, the soldering iron mic, and the fact that you sent your first attempt all the way to IM for the box of shame...I'm subbing. First rate all the way. Well done, man.
mixing in the rhythmic noise with the perfectly fitting soundtrack is genius.
29:53 wait... you don't weigh in your offcuts and chips for scrap value?
So, I'm watching this man make a very complicated gearbox to remove backlash. But so far he hasn't mentioned why he NEEDS no backlash whatsoever. What application needs this design?
I can't think of one offhand for something at home, but I've run into them at work for speed compensation gearboxes in printing where any backlash results in huge changes in print or cut quality
For some axis movement on his CNC machine. Any backlash will take your milling tool out of center
He should send the finished product to Elon Musk to fit into his rocket engines to reduce vibration.
I beleive it is in fact a "but"
Impressed by the sound quality of that soldering iron.
I love the cinematography. It feels like a noir movie mixed with one moment in Ferris Bullers Day Off when he breaks the 4th wall.
My goodness, that is a monumental project, for someone whose not an engineer.
You got balls
We need more over confident nerds like these making billion dollar companies look like amateurs, keep it up we the community got ur back
I have no idea what you are talking about with this entire video, but it has been satisfying watching you do it. GG
Not only am I impressed with your project, I'm super impressed by your video edits, story telling and sound design! Great video!
As somebody who's also not an engineer (at least, not of the realm where ctrl + z doesn't work), there was a lot of this I didn't understand, but still found entertaining. Great stuff!
Chevron gears can also be used to reduce backlash. Thanks for the video, very cool.
you don't gotta lie to kick it
@@skepticaldopefeind Excuse me?
Man, I love your dry humor. Most will not get it unless they have ran into similar issues with projects. My muse is more along the lines of experimental electronic component builds(for example working on an experimental TEG that is entirely printable, it's very touchy. Junction points as small as 1 mil (mil as the measurement mil and not millimeters. Average human hair is 1 mil.) and up to 5 mil. Graphite, graphene, and conductive inks ranging from nickel to gold. Sensitive enough to use sun light to generate. I currently have to draw them out by hand for test models until I get the measurements within a working tolerance. Tedious does not even begin to describe it.), so even though I do not know many of the ins and outs of machining I certainly feel your pain. Keep it up, you are making great progress! Looking forward to further videos like this. You earned a subscriber.
I know jack about machining but this guy turned a topic I'm not partial to learn about, and managed to make it entertaining enough that I, a young, distractible adult with ADD, watched all 30min without looking away😅
Arrived here from IM and have just hoovered up every minute of content you've so far put out. I've not done that amount of back-to-back UA-cam onsessive watching within the same day since I discovered Bobby Fingers. You're killing it - and making me realise that I need to embrace the Dunning-Kruger effect a little more in my own workshop. Nice one.

My favorite aspect of the video is how threatening you manage to look holding casually waving that soldering iron back and forth from a seated position; big Wilford Brimley energy
You got Leeloo The Fith Element to help unbox your bandsaw. Respect.
Came here to say this!
Milla Jovovich played the part of Leeloo
@@frankwolstencroft8731 blasphemy Milla Jovovich is played by Leeloo!
@@StephenTack Milla was born in Lviv, as was one of my daughters in law
A little something I learned 50+ years ago in school, but have never used. If reamed holes are slightly to small, offset reamer axis slightly, and, no, I don't remember how slightly, to make the reamed hole a bit larger.
I hope this actually works, as I have not personally used this technique in my over 50 years of machining.
CNC has changed what can be easily machined so much. I have a really long story about helping with the set-up for one of these gearboxes, back in the old days, but it will have to keep til I cross seeing the Southern Cross off my bucket list and perhaps visit with you.
its nice to see someone tap holes with a hand tap and not just sticking it in an electric drill.
That was really really interesting. It makes sense of the various references I've heard to genetics in the past several years. Thank you for the explanation.
Also I don't think it's boring at all. The fact that the works is more nuanced and subtle than before just gives us more to discover and use imho
Coolant is your friend, you can use a spray bottle. Or brush with oil. A few things, this type of drive system is going to be loud compared to constantly meshed spiral cut gears. Also the lash in the gears is there for a reason, as the parts are in use they heat up and expand. Having them too tight will make it very tight and create wear. Also the gap keeps oil flinging in between the teeth. The teeth are also hardened so i have not finished your video yet but i dont see any plans for heat treatment.
Another thing, you have no vent, this will create pressure as it warms up and cools, you need a vent in and gearcase or transmission or the seals will blow out.
That backlash is nothing to worry about. Get it hot and then retest it bet its tight.
the chips on the feet followed by the part being too long had me laughing so hard. So good.
Honestly for a hobbiest the finish and tolerancing on that machining is pretty darn impresive! I've only really seen better in a professional setting at work where we make aerospace parts. And even the guys on the shop floor don't get it right all the time either and we have to scrap more than you'd probably think.
I was going to build a turbo encabulator but this cycloidal drive peaked my interest.
17:44 Pro tip for unboxing large heavy things- 1. Flip box over so bottom is facing up. 2. Cut tape, and open up box. 3. Carefully roll opened box over so the bottom is facing down again. 4. Lift box off large heavy thing.
Or, have a friend who says "WTF have you bought _now_??" and helps you anyway.
i liked you as soon as you started talking. I like the way you do things, YOU FIND YOUR OWN WAYS. very aware of what may come if you were to go a certain route "foresee"
My new favorite channel of things I'll never do because I have no talent, I could watch this guy drill all day.
