UA-cam has demonetized my latest video because I use the words “ball” and “shoot”. I’m pissed off about it and am trying to contact an actual person to fix before I publish.
Ben's wife: "Honey why is the sauce pan leaking?"
There is now a tiny hole in every conductive thing in Ben's home.
Why is the dog leaking ?
Yeah every time I see his desk full of samples I imagine he goes around town covering all the street signs with electroluminescent paint, screen printing graffiti onto sidewalks, bending everyone's garden fences using ammonia.

Not only is this impressive machining, he provides an articulate and thorough explanation of how it's accomplished. Accolades!
Drilling through a lathe cutter is impressive. I've never thought about EDM for drilling. This is genius.
Hey Dustin!
EDM is used to drill the cooling channels in turbine blades and vanes used in jet engines.
Been doing this since 1981, not exactly a new technology. However, having it affordable for a home DIY'er or hobbyist IS exciting. I do mainly wire EDM.
Jordan Lapointe *Destin
SmarterEveryDay Dustin I found a video a little while ago that introduced me to EDM drilling. Try searching on UA-cam for “Drilling through pencil lead”. That’s where I became fascinated :).
>It'll be too conductive
>water your plants with it
It's got what plants crave. (Electrolytes)
oh god i love that reference
Plants love heavy metal
Mostly iron copper and zinc the nano particulates are what make the water more conductive not salts.
@@Barskor1 salts can definetly make water conductive, just adding a bit of tabel salt to water does make it conduct electricity quite well.
@@turk639 Yes but that is not what is happening here he used distilled water that over time gained higher conductivity by drilling.
A lot of years ago, I used one of these machines to remove broken drills, taps and hardened steel pegs from materials. It was extremely good at doing this and due to costing, worked out cheaper than re-machining the whole part again - mainly because I worked cheap.
For fun, I used to make strings of ball bearings, similar to pearls, from worn out bearings.
lol I read the last line wrong and was like... a ball-bearing thong doesn't sound comfortable XD
@@g60force Hmm, never thought about that but am thinking that a few odd nuts might make for interesting thing, for the very brave....

Go For It!!! Whatever Drills your hole!!! Right?
when I was younger my kid used to tell me stories of homemade EDM machines that I always dismissed as urban legend.
I've seen that baxedm stuff around, great to see it implemented. Looking forward to seeing your wire feeder / tensioner. I talk alot when I'm excited; moral of the story: Amazing work!!

@@channel11121 /r/whoosh
i'm pretty sure you're ordering parts right now Tony. Can't wait to see your version :-)
Dude, your vids rock, and this vid is freakin' sweet too!
Here's an example of how a DIY wire feeder and tensioner for Wire-EDM could look like: ua-cam.com/video/us3KhT7r01g/v-deo.html
I once had a conversation with an engineer - he talked about a project he was working on. It was about EDM machining; they used a wire about the thickness of a human hair. It was so precise that when you put two freshly separated pieces of metal back together and left them for a while, they'd fuse back into one piece. Since EDM is pretty slow, they'd devised a system which was able to re-inject a new piece of wire using a jet of water should the old one have broken when running unsupervised during the night or over a weekend. Fascinating stuff!
Did he mention the type of metal he was using?
I had need for such a machine several times in my shop life and only guessed that such a machine existed. Not till now has the concept been shown as being practical and affordable. Thank you.
Opens lots of new doors.
When I was in Grade 8, a buddy and I built an EDM drill starting from an article that had been in Popular Mechanics. I got a section of a many-splined transmission shaft to use as a "tool" from a shop that fixed Kenworth oilfield trucks. That was pretty hard, high-grade steel, and it was able to drill a close-fitting hole through a piece of 1-1/2" mild steel or aluminum plate. The plate being drilled was submerged in Kerosene in a clear Pyrex dish, so that the arc discharge was actually covered by the liquid. Raising/lowering the head for the cutting tool was a vertical slide made of maple, both the track and the movable head that ran in it. The maple slider holding the "tool" was raised and lowered by fly line running through a multi-line block & tackle made with Meccano pulleys. We got a very slow-turning gear motor out of a junked Timex watch display, which very slowly un-reeled the line, lowering the cutting tool. The speed for lowering the cutting head was one of the hardest things to get right. The winding motor wasn't variable speed or reversible - a hand crank raised the cutting head.
We cobbled up a circulating pump using an automotive-type mechanical fuel pump with the actuating lever arm moved by a maple cam on a bolt chucked in a 1/4" electric drill. We put a diode in one leg of the power wires to slow the drill down. We made a tapered glass tubing nozzle for the hose where it "squirted" at the workpiece. That flushed the cuttings away from the tool pretty well, although not as nicely as if we'd had a tool head with a hollow center to pump the Kerosene through. The cuttings built up quite quickly, and we discovered that things didn't work so well if the liquid was full of metal cuttings. The solution for that problem was to drain the kerosene full of cuttings into a reservoir. Some settled out, and the pump output ran through a Diesel engine fuel filter. Our high voltage supply was 120 VAC going through a voltage doubler or tripler power supply, using some big capacitors, some big incandescent light bulbs for current limiting, and some high-rating diodes we obtained by writing to a solid-state component manufacturer. They sent us a box with 2 or 3 sets as well as some heat sink material free of charge, which was good of them.
All this back in 1969 - 50 years ago - hard to believe. Later I became an electrical engineer, and belatedly learned just how dangerous this setup had been. But, ignorance is bliss, and we never had any shocks, big arcs, fires or major problems or failures, and it actually did cut really complex shaped holes through thick steel and aluminum. A buddy and I built this contraption and won 2nd prize at a regional science fair. We attended a really small school, with teachers who really didn't understand (fortunately) what we were doing very well. We figured we'd done OK, since about 80% of the parts were junk/scrap, begged, or donated, and the only "guidebook" we had was a Popular Mechanics article.
We bought the big capacitors from a motor & genset rewinding shop that worked on oilfield equipment. They got interested in what we were doing, and donated the mechanical fuel pump, a bunch of hoses, and a diesel engine filter housing and filters along with the fittings to connect it all up. They thought using an electric drill to drive the pump showed "ingenuity." We were pretty lucky to have people help us out with things like that, and the high voltage diodes.
It's sure a long, long way from where EDM technology is today. I went to an industrial trade show once, where some EDM equipment was being demo'd, and told one of the sales reps about the Grade 8 science fair project. He had a good laugh, and told me we'd been complete idiots. Which wasn't really fair - we built it with almost no adult help, solved all the problems, and made a working machine that actually drilled a 1"-1-1/4" splined hole through thick steel plate. We nicknamed the beast the "Spitzensparken" for obvious reasons. My friend's dad was a ham radio operator, so he knew something about high voltage wiring and insulation. We were pretty lucky in some respects. How many school science teachers today would let a couple of 13 year-olds build a project like this in the school lab?. We had parents who kept an eye on things but trusted us enough to be careful when fooling around with what was a pretty crude rig.
Agreed, thumbs up for volume.
Man that’s totally awesome!
I love that you got your inspiration from “Popular Mechanics”..... The internet’s of yesteryear!!!🤓😂😂😂
EDM would possibly be a cool way to fix a probe too a meteor. Drill and then weld. I’m wondering if you could torque steer the drill filament....🤓🤜🏼🤛🏼🤓🇦🇺
@Jim Baritone, what a story of genius at such a young age! You knew your calling. Typical of people who become engineers. I assume you are now retired and like me keep up with the journals and science news. Life is good! I knew my calling early in life (7th grade) and took a basic electronics course. I had no father to encourage me and help me make my dreams come true. The Armed Forces Schools gave me more training and I was able to secure employment at the White Sands Missile Range as an ET and later on an Engineer Assistant. I took college courses as necessary after returning from Vietnam to stay proficient and competitive. You did well Jim as a young dreamer and became one of the most coveted of career professionals in the world. Best of wishes!
Very cool and you sound about my age. Did similar crazy stuff from those mags all in the "lab" in my parents garage, they we always afraid I'd set fire to the garage and subsequently burn the house down LOL. I ended up going the scientist route but the thing I liked about what you said was about your science teachers. We had cool science teachers that were always "blowing thing up" and doing crazy experiments, I'd be a liar if I denied that they didn't have an influence on my later formal education.
Thanks for the essay.
I bet he's the kind of guy that never loses a chuck key.
If that's a requirement... I'm out.

who uses Chuck keys? i just use a vice grip.
@@Unmannedair haha, good I'm not the only one.
ha! I wired one key to my dp and have another on a 6" piece of 1/2 inch galvanized pipe as an extension. Works great for getting the chuck real tight.
@@johnpossum556 good idea, but I probably still lose it. Haha.
Not to mention he very clearly walks us through every step, so that novice to expert is in full understanding of form and function, as well as what and where to go-to for parts and programs for running it. Impressive. He clearly watched ALOT of Mr. Wizard as a youth. Thank you Obi One....
Running an EDM drilling machine in my CNC-EDM Wirecut shop too makes me be even more impressed about you having build yourself such a machine DIY!
It takes some really deep knowledge about electronics, the EDM process and also some decent building skills to get that done and finally to work!
BIG RESPECT! WELL DONE!
Me: "Huh I wonder how (any advanced topic here) works?"
Applied Science: "Here I've made this cutting edge technology in my garage, and made an great video about it."
Cutting edge. Ha... Ha... Ha...
Honestly, I'd love to get to know this guy, buy him a few drinks, hang out with him. If nothing else, I'm sure some of his smarts would transfer by osmosis to me!
@@Ariccio123 I second that
"Cutting edge" being 250 years old....ok.
@@vidznstuff1 Arc gouging technically may qualify as EDM, but I dare you to try making a 0.6mm hole with your welder.
I think hobbyist level EDM is going to make a large impact in the small/precision capabilities of the home shop
If you add in linear and oscillatory/elliptic processes you can end up manufacturing a LOT of nearly impossible to find parts.
still a long way to go to get precision out of it
It's more likely going to make lots of tiny little impacts of minimal force in the small/precision capabilities of the home shop
Seth Baker have you seen how much Bens setup costs? The baxedm psu is 2700 Eur alone! I dread to think what the total cost is - well out of reach of the average home shop
@@fourtwo7612 However it need not cost this much it is the current market that allows that pricing.
My brain just melted. What a great introduction to EDM, was very informational, thank you!
I've been a EDM programmer/operator for 25 years... When I started my apprenticeship.. EDM was in its infancy. I run Wire, sinker and Hole popping machines. Even after 25 years.. I'm still learning new and interesting aspects of the technology almost every day. Wire EDM is the most accurate form of machining available today. We regularly achieve tolerances of .00005. Currently my company has 8 Fanuc Wire machines along with several sinkers and hole poppers.
.00005 what? attometers?
@@yosyp5905 fifty millionths or half a ten thousandths of an inch

We are living in amazing times, but still can't wait for the fusion reactor for hobbyist so I could run all those amazing machines cheaper :D
I EDMed a 1/2" wrench once while replacing batteries in a room sized UPS. A few hundred amps is all you need.
I know someone who welded a wrench using the same technique.
Thinking about it, you could make a pretty easy high current welder/arc furnace using a few truck batteries.
My co-worker EDM-d about an inch off the end of her torque wrench, when tightening the bolts on bus-bars for a submarine battery. I believe it's ok to say this, because I found the specs on the internet: I'm talking about a 260 volt battery with a capacity of more than 10,000 amp-hours for each 2 volt cell. Each cell weighs 2,100 pounds. The total of 128 cells has stored energy of 2,600 kWh, and weighs more than 130 tons.
Everyone off the buss! It's pretty amazing what you can weld or vaporize with battery stacks. Used to be -48V for phone plants was The King here, but a lot of datacenter UPS battery plants can do it now.
i EDMed a new profile on my calipers with a 28v aircraft battery, you won't believe how efficient and fast that technique is
Out in the field, some people stick weld with 2 car batteries and jumper cables
Thanks to your video, today i have successfully removed a broken screw tap from an aluminium heatsink. It was metric 3 and 6 mm long . I have done with a constant current lab supply with 10 amps and 24V. Rotation with a hand drilling machine. Thank you! Without you i don't think i could done it.
18:20 this is some weird sounding EDM, i guess you can call anything music nowadays

@@iangraham5320 i think you had those to start with.
The world deserves a collab between Applied Science and This Old Tony.
Completely agree! :-)
Now he can drill trough his drill.
"In fact I have been able to drill through / ruin, every single conductive thing in the shop" lol ....
forgot to check if his camera
This has some useful automotive applications that I can see, namely adding safety wire to parts that didn't come with it. Very cool, thank you for showing this demonstration of your open source hardware table you built and the length of explanation of how and where you acquired the bits necessary to replicate.
This is amazing, I pick up my jaw after seeing the tungsten bit with some small niddle through it!.
I choose to believe that it’s Electronic Dance Music machining.
... straight into the brain.
When it comes to electronica, EDM machining is far inferior to IDM machining or EBM machining.
You could modulate the power supply to create music... So while stupid and unnecessary EDM machining should be possible
Choose to believe it's edm
Choose life...
@webnothing Careful, don't anger the pixies.
You sir, are brilliant. I don't usually leave comments, and this has nothing to do with anything I would ever be involved in, but I found this very fascinating and articulate.
I love the level of detail that you include on the engineering of each specific component and process for those of us that love the minutiae.
I run Makino sinker EDMs and the capabilities of the machine is nuts! Super precise and some materials we also use for machining is Graphite/Carbon. There is different types of PoCo as well.
The complexity and variety of projects that Ben works on is amazing.
Always so thoroughly explained, too.
Every video is a must-watch for me. Keep up the good work. ;)
That is the reason why you and others should continue to educate yourselves,
learn proper English, be articulate and accurate in one's descriptions.
That is only achieved when one has an extensive vocabulary.
Learn from the example in the video and always strive for excellence.
Perfection is NOT achievable ... Excellence is!
I had no idea this process was accessible. Thanks for the share.
I never saw drilling like this. Is incredible. Beautiful technology.
I have done it on some aerospace projects at the machine shop I worked at in Highschool. Were were not told exactly what we made as it was for the airforce. Was really cool to drill such timy holes through titanium
I haven't seen EDM in decades. Guess I really haven't found a need for it lately. We used carbon electrodes for drilling holes but we also had electrodes in special shapes which were used to essentially cut precision curved slots in hard to machine aerospace materials.
Our coolant setup was very different from the one described. Coolant was similar to ordinary low pressure, high flow spot cooling for other machine types but the conductive coolant was different.
Who would've ever thought that drilling a freaking hole can get so cool
Even the tiniest things in life have the biggest amount of engineering behind them, it's really interesting to investigate the engineering and science behind some basic things we take for granted. I'd definitely watch Technology Connections' videos on these kind of things as they are seriously awesome.
Dudes building megaliths.
Of course ben makes his own EDM machine! I expect a fully functional fusion reactor by the end of the week.
Edit: just wanted to plug this excellent Japanese tv show called supreme skills which is sort of a game show for Japanese scientists and manufacturing specialists. Heres an episode where they use a manual lathe and EDM drilling to drill through a pencil lead: ua-cam.com/video/pCtWPbTDbuY/v-deo.html

Looking forward to seeing how the wire EDM works in the X Y axis. Thanks for the great video as always!
The craziest part about wire EDM is that the top and bottom guides can move independently which means you can cut some crazy shapes with odd tapers. Even a shape with a square on one end and a circle on the other, with one singular cut
Amazing work and amazing narration of the project. I want one! Thank you so much!
Now this is the kind of EDM I can get into.
I won't pretend for 1 second to have understood everything that was going on.. But, it certainly is mesmerizing.. Thanks..

I’ve seen this before and forgot how interesting it was, thanks again. great video.
*Applied Science* I collect Niobium and Ferro-Niobium, would love to see you drill through the crystalline as well as solid bar forms using the EDM method. You are also the one guy who may be able to melt it in the home shop. Usually an electron beam welder type device is used to melt it, I had always wondered if a carbon arc mini foundry would be capable.
The local engineering shop that I frequented during my formative years on the farm had one of these units, and you could 'eat' out a broken off bolt/stud/whatever - it used what looked like a 1/2 horse electric motor, that had been reconfigured to be an electromagnet; the circuit ran through the armature and back through the work piece.
When you applied the lever and brought the tungsten electrode into contact with the work piece, it energised the armature and the the electrode was pulled away from the work piece and created your arc, thus eroding the part a little.
Repeated application of the electrode kept eating away at the part until it was (most;y) removed, allowing the broken part to be extracted.
Magic!
Don Pollard no. magic is not real.
electricity is real.
makes me think of lift-start TIG welding.
Working on an old steam engine--might have an application.
Could be a game changer for making solder paste stencils!!! This project is on my "To Do" list for sure, good stuff.
Thank you 20 years of wondering just how EDM works answered in 30 minutes and Im an engineer!
Don't even know what I'd use it for but I want to build one.
Ev3rMOr3 - more impressive is EDM wire cutting. You can do amazing things with it, cut some very complex shapes. I'd love to have one but I can't imagine this thing being cheap, even if I built it myself
@@richmac918 yeah I watched the guy with the edm machine that acts like a bandsaw. Cut was near perfect precision.
How about drilling .3mm holes through an aluminum front panel in any symbol configuration, so that you hardly see the holes until you shine an LED through them? Bonus points for voronoi stippling patterns, or a nice phylotaxis spiral for some subtle speaker holes. You can make them practically invisible to the naked eye with an ion beam but I'm guessing that's a little more involved.
Same here!
the way is the destination :D

And this ladies and gentleman is why i love this channel, I seen a EDM machine in a clients machine shop, and I didn't understand the science behind it, And now I do ! Amazing technology. i wouldn't be surprised if this technology dates back to the 60's, now with opening up of patents we can now start benefiting in a small shop environment much like 3d printers.

"half a thou of an inch"
me: *screaming in metric*
"Half a thou of an inch" is quite understandable by anyone in mechanical engineering or anyone with a machining background. It is simply 1/2 of 1/1000 of an inch >>> or 0.0005". Then .0005 inch x (25.4 mm/inch) = 0.0127 mm. ...... Ed
Also common for engineering and machining is "mils" where "1/1000th of an inch" is also called "1 mil". So "1/2 mil" also is equal to .0005".

@@allesklarklaus147 He promised it to Patreons like 4 years ago or something, still nothing afaik.
@@JustinAlexanderBell oof
Fantastic narration, explanation, work, and all the stuff.
I am going to have to get one of these going asap. I have had so much trouble drilling offset holes in uneven surfaces. This is like the holy grail of holes. The Holey Grail.
I've been subscribed to you for years and years, and you still manage to astonish me with your incredible science experiments. Thank you for all you do!
Commonly used to remove broken taps a demo would be nice, the EDM machine I witnessed removing a tap was 30 years ago.
Yeah it's been around a long time. My friend used to EDM Alum extrusion dies in the 80s.
That makes sense! Thanks for that thought.
tfp777 we had a machine like this back in 1964 at the Naval ordnance plant.
Yes I had one 40 years ago it was called a taps disintegratior it was made in Australia:-)
@@hillorystanton6209 thank you for the info by the way last same last names
From decades of working with analog power supplies filter and shielding and low noise ultra fast soft recovery diodes help a great deal . Wire management also reduce antenna effects of un-shielded wire . Faraday cage does work also . Enjoyed the video keep up the fine work.
I'm a reverse code engineer by trade but holy geeze... There is some unidentified logic in my brain that is inherently inquisitive about the ability to drill a teeny tiny hole through almost any conductive material you can imagine... These materials were specifically produced in order to resist the most abrasive materials and processes that man works with yet its almost as if you've managed to just push a small pin through them as if they were butter... So freaking cool! What I really want to know though is how the heck they create such a teensy tiny hole in those conductive rods that are already ridiculously tiny.
Would you consider doing a video about graphene chemical vapor deposition?
Esra Erimez graph vapor d is easy get roll of copper put it in a methane atmosphere and cook it at high temps. u need to put seed xystal on the copper. I would like to see some en.wikipedia.org/wiki/Electron-beam_lithography he already has a scope he could mod.
@@Amipotsophspond It would be a short video for sure. The process is actually very simple - it's the science behind it that's complex. Kind of like nuclear, it's actually very simple in concept, but the finer details are what gets ya.
Perhaps titianium nitride or gold vapor deposition?
@@actiglow I imagine depositing gold could be done with something akin to a plasma welder. I.e. HF arc between gold electrodes and blowing it with a suitable gas (likely argon or hydrogen, for not being in the way when the layer builds) onto the target. Maybe use magnets to focus the arc for better sputtering of gold when hit by plasma (higher current density==higher temperature to get a mix or sputtering and PVD).
This could allow high-res additive manufacturing, by way of depositing a conductive film, printing/exposing a mask, followed by stripping the mask and briefly wet-etching the thin film.
The aspect ratio is limited by the mask's aspect ratio, not by the ~0.5 you get from pure substracive wet etch (aka traditional PCB process).
You could fill the voids from mask stripping with something and repeat. Note that buried vias are trivial in this technology, as well as buried semiconductor dies which are prepared for flip-chip mounting (though they might be preferred without balls).
We use a wire EDM at my workplace to cut certain metals and I'm learning how to operate the machine, but this video was great for explaining how the process works. I'll be looking forward to what you have to show with regards to wire EDM processes, but this drilling process was quite fascinating.
I'm glad I watched this when I randomly woke up at 2 am this is really cool
I needed that drill set up yesterday.
Seriously.
Very cool
I am very pleased with OpenBuilds components.
You do an excellent job of explaining all of this.
Thank you!
This vid is a year old now but I think you could put together kits or whole assemblies and do quite well. This is an awesome tool and video. Thank you.
Can we see inside the arc generator please!
I second this!
Please!!!
Check out my channel, I have a video (ZwFVmkptS00 from 14:50 onward) of the BaxEDM generator with a peek inside :)
Watch it (in great detail) on Mike Bax's UA-cam channel! (BAXEDM) in Mike's own words ;) ua-cam.com/channels/y4kgsAYxcraee8w5SfqXPA.html
