As a watchmaker I love this video, many folks don't understand how difficult drilling sub 0.5mm holes can be, I routinely machining holes this small and its very challenging, especially when you are using a drill that's only 0.1mm in diameter, I drill pivots often and when drilling these holes it takes up too 1 hour to complete the hole at just 2mm deep, love the content Adam!!!
Oh yeah, the drill bit is so small, that it can (and probably will) flex when drilling, so you have to go extremely slowly. I'd even had this happen with 1/4" drill bits in a drill press. If the surface you are drilling is not 100% perpendicular, you get lateral forces on the bit, and the bit will flex off axis. Which not only means your hole is not where you wanted, it's an easy way to break a bit.
What kind of lubrication do you prefer for micro drilling? I use the same blend of silicone and paraffin wax that i make for the piercing saw. It adheres to the blade or bit then melts when heated by friction. Some people refer natural beeswax and swear it lasts longer than commercial brands. It appears that Adam was raw-dogging those holes.
@@DonariaRegia Was that brush for debris or lube? Otherwise I'm baffled Adam seemed to be using no lubricant whatsoever, and hardly anyone commenting on the matter. So, I was _expecting_ breakage, expecting it more often, actually.
I have literally zero need to ever drill holes even close to this small or this precise, but now I want one of these! The craftsmanship it takes to make a machine capable of this is absolutely impressive.
I find it oddly soothing when Adam is working on something and everything he needs is right within reach, just lean a little this way or that and it's right under his hand, ready to go. It's goals for me.
Adam you are a hero to me. You showed me that working with my hands and doing stuff myself is fun and rewarding. When I was a kid it was mythbusters. Now we are both older and I think the love for making and designing stuff has grown even more. Thank you for all you do

My dad told me a story about a German that made a very small precision drill bit, and sent it to a Swiss machinist, for bragging, and the Swiss machinist _bored a hole down the center of the bit_ and sent it back.

there is a story about a local factory that made gauges being bought by a swiss company in the 60's. Keen to show off their prowess they drilled a ridiculously small hole in a coupon and sent it off to the new head office in Swizerland. A few weeks later it was returned with the instruction to look at the hole more closely... so they did... head office had put a thread in it 🙂

@@jackseney571 No, I mean 1:148 😂 It's N Gauge/ N scale as known in the US. There are scales smaller than that, but even at 26, I think this is fiddly enough
@@g60force US and European N scale is 1:160. Japanese N Scale is 1:150 and UK is 1:148. Not sure why they decided to make them all just slightly different
Great vid Adam. Though the reason that they didn’t put levers in the handles, is you loose a lot of tactile feedback with one, and can over apply force and more easily snap bits, versus the direct feedback through your fingertips in the control handle. Yes, the company thought about putting in a lever. Also try to not apply enough pressure to get that motor to lag down. That, with those (just like a normal drill press) is an indication that you are applying too much pressure to your drill bit. The key, especially with those, is being gentle. Look into Los Alamos Labs for some of the uses of those.
Good advice - plus always add more cooling and/or lubrication that you thought you needed with any tool under a milimeter. A larger tool can shunt friction heat without warping significantly, but such tiny pieces of metal lack the mass to do that. That's another reason Adam broke bits so quickly.
I am thoroughly flabbergasted by this press. The threaded holes in the table to the finger nuts and brass clamps that you made. I haven't wanted a tool this badly since I got my first Dremel at 12, in 1989
Useless trivia most wont care about but a team of scientists from Cardiff University have entered the Guinness Book of Records for creating the world's smallest hole. The four professors from the university's manufacturing engineering center have created the smallest-ever drilled hole, which is less than half the width of a human hair at 22 microns using EDM electro discharge machining
And what exactly is it? Width of human hair can range from 40 to 120 micrometers. With drills that is 0,1 mm (100 μm) easily available, 50 μm doesn't look like much of an achievement. Now if it was less than 20 μm, that's already something.
@@d4slaimless 22 MICRONS a human hair varies from 50 to 80 microns and was drilled using EDM , electro discharge machining . I never gave numbers because like i said i figured no one would care , so thanks for that . Have a good night
@@waynesbutler7834 According to National Institutes of Health The adult human hair is around 20-180 µm in width. According to wiki it is 40 to 120. So I had to ask. Thanks for info.
A very special Dumore precision drill press with a round table, covered with tapped holes, attached to a screw-feed driven compound slide assembly that allowed longitudinal and traverse movements. Each axis was fitted with a dial indicator and the table's elevation, by rack and pinion gearing, incorporated a micrometer depth stop with an especially large dial. For accurate spotting a microscope was also fitted. The unit, which might have been made by the English concern Kelston Engineering in Fishponds, Bristol (who built Dumore machines under licence) was supplied to the Ferranti - once an important company prominent in power grid systems and defence electronics
I love that Adam seems to think the same way I do. The more you think about a problem the deeper and more exciting the rabbit hole goes. I could nerd out for hours on some of the most mundane things.
Oh my goodness, there is so much ADHD energy in this video, and I am here for it. That precision drill is absolutely fascinating, and I will never stop being amazed at the creativity and knowledge necessary to conceive of how to make such a tool.
@@audio323 bruh adhd is, in my own opinion, simulant addiction so yes . At least that's how it feels to me sometimes. ADHD is like your brain constantly searching for stuff that's interesting to focus on. and if what the person is doing isn't interesting, boom look a squirrel.
I'm a novice maker in the field of 3D printing and these videos scratch an itch I didn't know I had (I kinda knew I did). Everything in it's place, and a place for everything. Adam Savage you are the man. God bless you and the Myth Busters.
Adam I found your drill in an old Dumore Catalog, it's a Dumore series 27 precision micro drill. It's listed in the 1957 catalog and is for sale on eBay now.
I am so envious that Adam gets to spend his time on stuff like this. My life feels like endless toil for just enough to scrape by. I hope that some day I am able to enjoy the things I wish to enjoy without constantly worrying about if I can buy groceries next week or make my next mortgage payment.
As an architect, I really love the verbalisation, the visualisation, the body language/gestures, and narrative that are part of the creative process. Adam does this in spades
Everytime i watch Adam doing stuff like this I get the feeling his life will be too short. For many, like myself, when it ends it will be OK. But for Adam, even though he lives to be 150 years old, it will never be enough. The ideas, the enthusiasm.. You can´t fake that. Really enjoying the content man!
Forty years ago I had one of those Dumore drill presses in my lab that I used quite a bit. I drilled a lot of holes with it, mostly prototyping circuit boards. Good little machines. I wouldn't mind having one now that I'm retired.
I have that same drill chuck. But it’s on a spring loaded arbor and has a wheel mounted in a bearing. This allows you to chuck it up into a normal collet and then hold the wheel with your fingers and feed the drill by pulling it down with your fingers. It’s very handy
That was really cool learning about backlash and the solutions. My RC hobby uses some of these solutions for the gears etc. Cool to learn why grub screws are used in different ways.
It looks like maybe someone pulled the table from an old series 27 from the 50s. They also made a magnetic chuck variant for the series 27 that looks pretty nifty!
It is a series 27 minus some parts. Looks like Dunmore used the same drill head as the Series 16 has. Dumore Micro-Drill Series 27 Model 8248 manual out at Vintage Machinery site.
Wow Adam takes me back to watch repairing and drilling with drill bits you can barely see and drilling out broken screws and Chasing the threads before making a new screw Sadly poor health doesnt allow me to do that anymore hands are no longer steady enough.
Adam, your enthusiasm is so addictive, I love your videos! Thirty-some years ago, I heard something that may be a rumor: A US manufacturing and machining plant made the smallest known drill bit for fine machining. It sent a prototype to a Japanese machining company with hopes of selling it abroad. A few weeks later, it received the bit back with no comments in the package. Upon microscopic inspection of the bit, they discovered a tiny hole was drilled through it! Take that Yankees!
This is the best, no …… THEE bestest Action, Romance, Adventure, Documentary movie I have seen in 20 years!!!! I be searching for that doppelgänger drill press to add to me shop now. It will complement my Sherline sensitive setup. Many thanx Adam for putting this one on….
So, before the actual building of the base commenced, my brain came up with the following: Have you considered the old-school sewing machine cover design? A cover (with handle) that latches to the base, with compartments that fit around the machine when the cover is installed seems like an elegant solution.
About drill bits. Minnesota twist said they made the smallest drill bit and sent it to China and China sent it back with a hole drilled thru it. Amazing tech !!
to china you say? they just bought a pack of dried noodles and sent the drill bit to that guy? or they just wrote CHINA on the envelope and put their faith in China Post?
And the true story, I've seen it with my own eyes. The country was West Berlin, and it was more friendly competition back then, there was the war time recovery and active trade between west and east; heck the soviets did not even mind the US flying bombers overhead (they bombed.. with candy bars. It was kinda cute, but also air-dropped supply's) The western company (dont recall the name, but I belive it was absorbed into Bell and know it eventually made its way to Boing whom now loans the artifact out) Anywsy they drilled a hair and sent over the drill bit in the hair thinking of it as a trade offering but whoever they sent for sales must have been too combative in thier sales pitch because instead of getting an trade order or a request to trade intellectual prorperty a few months had passed and the soviets had used thier electro-machining technology to drill a hole inside the drill bit that was left as a sample. And we traded for the soviet intellectual property, and that is how we got E.D.M. technology in the west. The R&D for EDM would have bankrupted our system unless there was a govermental purpose behind it, and same applies for the Soviets... But all industry in the Soviet Union was govermental in nature. Also what they sent was tempermental in nature, because of the nature of a state ran economy they did not have the means nor pressure to supply the same level of voltage regulation as in the west, and for a EDM that means the machines where more art then science to operate. (Like literally did not have pressure to regulate volts better thier computer and automation tech was based on wholy diffrent principles to the point that they used trinary because it saved electricity and allowed logic gates to be multi-functional despite taking much more labor to learn how to use)
As someone with ADHD also, me watching you not only manage your cerebral proclivities and talk through what’s happening in your head but also harnessing your spiciness to just be an awesome maker, has been such a pleasure to watch over the past 20 years. So thank you for keeping your process raw; I think it helps with exposure to people who don’t understand how it can be disabling, how it can be harnesses, and how you can live with it ❤ I’ve taken what I’ve learned just simply watching you to help with skills at work and in life.
After rewatching, yes, I watched it twice, I was wondering, what kind of lube are you using on the bits? I used to work in the aerospace industry and had a contract with Boeing for certain aluminum parts, on certain specific planes and they supplied us with BoeLube. It worked fantastic to keep the bits cool and prevented unwanted binding and breaks.
From what I understand, it’s only a felony if you are trying to pass it off as a denomination other than what it is. Like if you tried to make it look like a nickel, or somthing like that. You can destroy your own money, no problem. As far as I know anyway
@@helloimzane Any mutilation or defacing is considered a federal offence. For example, trying to pass off a damaged coin as one with a mint error in order to sell it for more money.

@@tested Our shops are both our livelihood and refuge, hobby and profession. Any improvement in the shop is as much if not more of a joy than a major project for outside of it. Tools, toys, organization, it all feels like a part of ourselves, and we can upgrade it!
Adding a lever like that is probably not good for something that small. You're easily putting too much pressure on the drill bit without feeling it. Hence the snapping of the bits.
I was thinking the same thing - the lever is /pretty/ no doubt, but definitely not practical in this scale. His feed rate/force was obviously too high so the drill broke.
Yeah, ideally there'd be some sort of reduction gearing mechanism - between his extension lever & the existing adjustment knob - that takes out the huge amount of extra torque.
The lever allows you to use a single finger to operate it instead of your whole wrist, which is way more ergonomic and easy to be precise with your application of force
Adam, I am falling down laughing.🤣 I was watching UA-cam videos, and the clip for this video came up, and played its short intro. And you said “Series sixteen”, . . . And my iPad promptly responded that it had set an alarm for 1600. Well done!👍
The unit, which might have been made by the English concern Kelston Engineering in Fishponds, Bristol (who built Dumore machines under licence) was supplied to the Ferranti - once an important company prominent in power grid systems and defence electronics - and, in 1951, the maker of an early computer, the Ferranti Mark 1
They're still around, going by the name "Kelston Actuation Ltd", and still making all sorts of custom screw jacks & precision lifting systems, also still based in Bristol.
Old hand plane users, such as myself are quite familiar with backlash. We have that problem with our plane adjustment knob. Stanley has always been notorious for that, because as you mentioned, tolerances were a lot different ages ago. Because of that, we find ourselves often turning the knob almost a complete revolution before the adjuster engages. Just wanted to share that.
Hey Adam! It was super interesting hearing about the x-y stage on your new drill. I work in a laser lab, and all of the x-y stages I use are spring loaded to prevent backlash. Even still, we are coached to approach a mark from the downhill side of the screw (twisting uphill to make sure it’s under tension the whole time, minimizing backlash). I was wondering if that’s something you do during your precision machining. Long time viewer, Bay Area native, love everything you do.
Ther is NO law against destroying currency. Defacing to misrepresent is the felony. Once it’s your money, you can do whatever you want to it except try to make it a different denomination. I actually went through all the comments to find this because I knew someone was gonna say it.
Now that you can make precise micro holes, now it’s time to make a micro vise to hold the micro parts in the micro milling machine you now have. You will need to make a micro box to hold and organize the micro holding tools… maybe it’s time to make a scale model of your shop to put the tool in… I can see how this can get out of controll.
The mechanical engineer in me enjoys hearing about the precision of the drill press, but the obvious shakiness and movement of your work table has me rolling my eyes?!
It’s not only the table. The floor in the shop is made of plywood. Not exactly the most rigid floor material. The wobbly phone stand doesn’t help either 😂
Converting an imperial measurement of 5/1000ths to a FRACTIONAL metric measurement of 1/8mm kinda misses the point of metric and I’m not sure he was being ironic. 😔
@Albuerum, in my experience as an Electronics Engineer, I found that my Mechanical counterparts and our machinists use fractions of millimeters all the time. It takes time to get used to. And yep, it is still annoying to me 😅 Them: "One tenth".. Me: "...of a meter? A millimeter, a micrometer?" Them: "One tenth of a millimeter, of course!" Me: "Well obviously. So, you mean 100 micrometers, right?". Them: "Sure". I don't see the benefit of not using an absolute number instead of a fractional and implicit expression.
@@mstjerning8919 My 4 year old understands math is a fundamental law of engineering. I'm not hiring a engineer that can't adopt or evolve or even comprehend the difference between the metric and imperial system of measurement, and worst of all steadfastly refuses to learn anything or adapt.
I worked as a land surveyor for 16 years. I'm good at knowing distance. You are working at a distance I've never dealt with. I wish I would have gotten a chance to work with you Adam.🤠
We had a production lines that had to drill small holes: smallest being 0.0065 inch: six and half thou: those drill break if you sneeze at them. But we didn't have anything like that x-y table. Nice machine. I'd have thought a wooden box to house the press would be nice and it could fold open revealing small compartments holding all the fine tooling you need for a such a thing. Because for me, the issue would be that all of that is very delicate and you'd want to be able to put it away where it's protected from harm and tool loss.

Though the reason that they didn’t put levers in the handles, is you loose a lot of tactile feedback with one, and can over apply force and more easily snap bits, versus the direct feedback through your fingertips in the control handle. Yes, the company thought about putting in a lever.
Also try to not apply enough pressure to get that motor to lag down. That, with those (just like a normal drill press) is an indication that you are applying too much pressure to your drill bit. The key, especially with those, is being gentle.
Look into Los Alamos Labs for some of the uses of those.
Good advice - plus always add more cooling and/or lubrication that you thought you needed with any tool under a milimeter. A larger tool can shunt friction heat without warping significantly, but such tiny pieces of metal lack the mass to do that. That's another reason Adam broke bits so quickly.
I am thoroughly flabbergasted by this press. The threaded holes in the table to the finger nuts and brass clamps that you made. I haven't wanted a tool this badly since I got my first Dremel at 12, in 1989
Useless trivia most wont care about but a team of scientists from Cardiff University have entered the Guinness Book of Records for creating the world's smallest hole. The four professors from the university's manufacturing engineering center have created the smallest-ever drilled hole, which is less than half the width of a human hair at 22 microns using EDM electro discharge machining
And what exactly is it? Width of human hair can range from 40 to 120 micrometers. With drills that is 0,1 mm (100 μm) easily available, 50 μm doesn't look like much of an achievement. Now if it was less than 20 μm, that's already something.
@@d4slaimless 22 MICRONS a human hair varies from 50 to 80 microns and was drilled using EDM , electro discharge machining . I never gave numbers because like i said i figured no one would care , so thanks for that . Have a good night
@@waynesbutler7834 According to National Institutes of Health The adult human hair is around 20-180 µm in width. According to wiki it is 40 to 120. So I had to ask. Thanks for info.
How did they make it with EDM? Don’t you need a hole in the part to put the wire through to then allow for EDM?
@@dabearsfan9 You’re thinking of wire EDM, but there are other forms of EDM like sinker EDM and hole drill EDM
*I need a whole ASMR video with Adam saying Oak box* in that special way among other good words.
My life need this. Okay. Its important
A very special Dumore precision drill press with a round table, covered with tapped holes, attached to a screw-feed driven compound slide assembly that allowed longitudinal and traverse movements. Each axis was fitted with a dial indicator and the table's elevation, by rack and pinion gearing, incorporated a micrometer depth stop with an especially large dial. For accurate spotting a microscope was also fitted. The unit, which might have been made by the English concern Kelston Engineering in Fishponds, Bristol (who built Dumore machines under licence) was supplied to the Ferranti - once an important company prominent in power grid systems and defence electronics
Yeah... I don't want "a" Dunmore drill, I want this one....
Ferranti, who have an AC voltage "effect" named after them.
I love that Adam seems to think the same way I do. The more you think about a problem the deeper and more exciting the rabbit hole goes. I could nerd out for hours on some of the most mundane things.
Oh my goodness, there is so much ADHD energy in this video, and I am here for it. That precision drill is absolutely fascinating, and I will never stop being amazed at the creativity and knowledge necessary to conceive of how to make such a tool.
I admit that weird energy makes me feel very uneasy. Like I want to, somehow, send him meds.
As soon as he said Oak Box I realised what I’d been noticing and came to the comments. What I had noticed was myself. Heh.
All the stims and fidgetting and nerdery without ever explaining it fully makes me giggle from how much i relate to it, this man is my adhd icon
Makes me think low dose shrooms lol. Or some other stimulant
@@audio323 bruh adhd is, in my own opinion, simulant addiction so yes . At least that's how it feels to me sometimes.
ADHD is like your brain constantly searching for stuff that's interesting to focus on. and if what the person is doing isn't interesting, boom look a squirrel.
I'm a novice maker in the field of 3D printing and these videos scratch an itch I didn't know I had (I kinda knew I did). Everything in it's place, and a place for everything. Adam Savage you are the man. God bless you and the Myth Busters.
Wow, Adam Savage moved to tears (almost) by this find and acquisition. I can totally relate! What a great, unique and prescious tool!
Adam I found your drill in an old Dumore Catalog, it's a Dumore series 27 precision micro drill. It's listed in the 1957 catalog and is for sale on eBay now.
wonder if they saw this
20:27 perfectly describes why LLM AI answers from the Internet will never be as useful as a competent search engine.
Mr, Savage:
your infectious joy at finding excellence in machine design is a delight.
I am so envious that Adam gets to spend his time on stuff like this. My life feels like endless toil for just enough to scrape by.
I hope that some day I am able to enjoy the things I wish to enjoy without constantly worrying about if I can buy groceries next week or make my next mortgage payment.
Im so happy Adam has youtube so we can watch his chaotic energy as a living journal for such a creative fun mind 😊
As an architect, I really love the verbalisation, the visualisation, the body language/gestures, and narrative that are part of the creative process. Adam does this in spades
Love to watch this guy! :D For me its just so relaxing to just watch and listen what Adam says and shows us. Thanks for another great video!
Everytime i watch Adam doing stuff like this I get the feeling his life will be too short. For many, like myself, when it ends it will be OK. But for Adam, even though he lives to be 150 years old, it will never be enough. The ideas, the enthusiasm.. You can´t fake that. Really enjoying the content man!
Adam is the point where creativity and practicallity overlap in a very efficient and soothing way
I think that Adam Savage may be the first person in the world to call anything an 1/8th of a millimeter
Its a perfectly normal statement on my channel. :0
Forty years ago I had one of those Dumore drill presses in my lab that I used quite a bit. I drilled a lot of holes with it, mostly prototyping circuit boards. Good little machines. I wouldn't mind having one now that I'm retired.
Those “Clamps” are R2-D2 foot parts! You can’t fool us!!!
lol.
Love this video. Thank you!
I have that same drill chuck. But it’s on a spring loaded arbor and has a wheel mounted in a bearing. This allows you to chuck it up into a normal collet and then hold the wheel with your fingers and feed the drill by pulling it down with your fingers. It’s very handy
I am delighted that you have found that Dumore! Worked with machinists most of my professional life.
Please put that quarter into circulation, it would be interesting to see if someone ends up with it that watched this video
That was really cool learning about backlash and the solutions. My RC hobby uses some of these solutions for the gears etc. Cool to learn why grub screws are used in different ways.
Does the press have a force meter to tell you how much force you're putting on the bit? That seems like it would be necessary for something so tiny!
No it does not
Because a skilled artisan who actually uses these machines needs to *feel* resistances. That's the difference.
its amazing to hear the motor labor with a .010 bit. so much torque going through such a small rod....
10:18 At this point I get the distinct impression that zero drawings were made for this build 😂
Holes that small placed with such precision are amazingly satisfying!
surprising that the bit did not break sooner, considering that the surface being drilled is not flat, but contoured.
Plus he was not using any cutting oil.
I have never been more excited about a drill press it’s perfect for the things I build
It looks like maybe someone pulled the table from an old series 27 from the 50s. They also made a magnetic chuck variant for the series 27 that looks pretty nifty!
After 30 minutes of research, this is what I finally realized, also lol.
It is a series 27 minus some parts. Looks like Dunmore used the same drill head as the Series 16 has. Dumore Micro-Drill Series 27 Model 8248 manual out at Vintage Machinery site.
18:00
You, Sir, are a national treasure. 🤣 That pun just made my day.
I had a sack of .030 drill bits for unclogging MIG welding tips.
Wow Adam takes me back to watch repairing and drilling with drill bits you can barely see and drilling out broken screws and Chasing the threads before making a new screw Sadly poor health doesnt allow me to do that anymore hands are no longer steady enough.
Adam, your enthusiasm is so addictive, I love your videos!
Thirty-some years ago, I heard something that may be a rumor: A US manufacturing and machining plant made the smallest known drill bit for fine machining. It sent a prototype to a Japanese machining company with hopes of selling it abroad. A few weeks later, it received the bit back with no comments in the package. Upon microscopic inspection of the bit, they discovered a tiny hole was drilled through it! Take that Yankees!
at some point one has to wonder if its actually drilled at that point and not cut through with electricity
I hope that's true, but either way it's a great story!
This is the best, no …… THEE bestest Action, Romance, Adventure, Documentary movie I have seen in 20 years!!!! I be searching for that doppelgänger drill press to add to me shop now. It will complement my Sherline sensitive setup. Many thanx Adam for putting this one on….
So, before the actual building of the base commenced, my brain came up with the following: Have you considered the old-school sewing machine cover design? A cover (with handle) that latches to the base, with compartments that fit around the machine when the cover is installed seems like an elegant solution.
Love this idea ❤👍🏻
You geek out over your tools more than I do, and my friends think I'm weird. Thank of for setting the bar so high.
About drill bits. Minnesota twist said they made the smallest drill bit and sent it to China and China sent it back with a hole drilled thru it. Amazing tech !!
Apocryphal: I heard a similar story told in 1980 from a someone from Lebanon Pa but the country was Japan.
@@danpommerening3490 Likewise I heard it for glass tubes
to china you say? they just bought a pack of dried noodles and sent the drill bit to that guy? or they just wrote CHINA on the envelope and put their faith in China Post?
And the true story, I've seen it with my own eyes.
The country was West Berlin, and it was more friendly competition back then, there was the war time recovery and active trade between west and east; heck the soviets did not even mind the US flying bombers overhead (they bombed.. with candy bars. It was kinda cute, but also air-dropped supply's)
The western company (dont recall the name, but I belive it was absorbed into Bell and know it eventually made its way to Boing whom now loans the artifact out)
Anywsy they drilled a hair and sent over the drill bit in the hair thinking of it as a trade offering but whoever they sent for sales must have been too combative in thier sales pitch because instead of getting an trade order or a request to trade intellectual prorperty a few months had passed and the soviets had used thier electro-machining technology to drill a hole inside the drill bit that was left as a sample.
And we traded for the soviet intellectual property, and that is how we got E.D.M. technology in the west. The R&D for EDM would have bankrupted our system unless there was a govermental purpose behind it, and same applies for the Soviets... But all industry in the Soviet Union was govermental in nature.
Also what they sent was tempermental in nature, because of the nature of a state ran economy they did not have the means nor pressure to supply the same level of voltage regulation as in the west, and for a EDM that means the machines where more art then science to operate.
(Like literally did not have pressure to regulate volts better thier computer and automation tech was based on wholy diffrent principles to the point that they used trinary because it saved electricity and allowed logic gates to be multi-functional despite taking much more labor to learn how to use)
As someone with ADHD also, me watching you not only manage your cerebral proclivities and talk through what’s happening in your head but also harnessing your spiciness to just be an awesome maker, has been such a pleasure to watch over the past 20 years. So thank you for keeping your process raw; I think it helps with exposure to people who don’t understand how it can be disabling, how it can be harnesses, and how you can live with it ❤
I’ve taken what I’ve learned just simply watching you to help with skills at work and in life.
Drake took this as a challenge 😂
Underrated comment
After rewatching, yes, I watched it twice, I was wondering, what kind of lube are you using on the bits? I used to work in the aerospace industry and had a contract with Boeing for certain aluminum parts, on certain specific planes and they supplied us with BoeLube. It worked fantastic to keep the bits cool and prevented unwanted binding and breaks.
I use to drill a lot of holes back in the day. Then I got old.
Giggity
Now you are just poking 😂
😂😂👍
They got blue pills to fix that
Me too
It's somehow just so relaxing watching Adam Savage just Svagaeing around in his "little" shop :P
How many of those holes can you make till its a felony
From what I understand, it’s only a felony if you are trying to pass it off as a denomination other than what it is. Like if you tried to make it look like a nickel, or somthing like that. You can destroy your own money, no problem. As far as I know anyway
@@helloimzaneYou are correct.
@@helloimzane Any mutilation or defacing is considered a federal offence. For example, trying to pass off a damaged coin as one with a mint error in order to sell it for more money.
@@grntitan1 He is not. Look for my comment regarding 18 U.S.C. 331.
@@treasurerFinleyASC “However, remember that fraudulent intent is critical to violating 18 U.S.C. 331.” As long as you aren’t trying to reenter them into circulation, it’s not fraud. I doubt Adam is planning on putting that quarter back into circulation, meaning it’s his to destroy if he wants
Don’t apologize Adam, your videos are super interesting!
I love how we as makers spend as much time working on the tools for our shops as we do on actual projects 😂
RIGHT???!!!
@@tested Our shops are both our livelihood and refuge, hobby and profession. Any improvement in the shop is as much if not more of a joy than a major project for outside of it. Tools, toys, organization, it all feels like a part of ourselves, and we can upgrade it!
I don't get envious that often but that is a nice machine.
Adding a lever like that is probably not good for something that small. You're easily putting too much pressure on the drill bit without feeling it. Hence the snapping of the bits.
I was thinking the same thing - the lever is /pretty/ no doubt, but definitely not practical in this scale. His feed rate/force was obviously too high so the drill broke.
Yeah, ideally there'd be some sort of reduction gearing mechanism - between his extension lever & the existing adjustment knob - that takes out the huge amount of extra torque.
No usually there is a 10,000 hr hand operating it. Not hamfisting it.
@@jasonpowley4913for real. That little rinkydink lever ain't doing shit to mess anything up
The lever allows you to use a single finger to operate it instead of your whole wrist, which is way more ergonomic and easy to be precise with your application of force
Adam, I am falling down laughing.🤣 I was watching UA-cam videos, and the clip for this video came up, and played its short intro. And you said “Series sixteen”, . . . And my iPad promptly responded that it had set an alarm for 1600. Well done!👍
The unit, which might have been made by the English concern Kelston Engineering in Fishponds, Bristol (who built Dumore machines under licence) was supplied to the Ferranti - once an important company prominent in power grid systems and defence electronics - and, in 1951, the maker of an early computer, the Ferranti Mark 1
Made high power radio tubes for radar systemes, UHF comm ones as well.
They're still around, going by the name "Kelston Actuation Ltd", and still making all sorts of custom screw jacks & precision lifting systems, also still based in Bristol.
Old hand plane users, such as myself are quite familiar with backlash. We have that problem with our plane adjustment knob. Stanley has always been notorious for that, because as you mentioned, tolerances were a lot different ages ago. Because of that, we find ourselves often turning the knob almost a complete revolution before the adjuster engages. Just wanted to share that.
Phrasing
_"Seriously... Are we not doing 'phrasing' anymore?!?"_
*Such* a great show! 🤣
Hey Adam! It was super interesting hearing about the x-y stage on your new drill. I work in a laser lab, and all of the x-y stages I use are spring loaded to prevent backlash. Even still, we are coached to approach a mark from the downhill side of the screw (twisting uphill to make sure it’s under tension the whole time, minimizing backlash). I was wondering if that’s something you do during your precision machining. Long time viewer, Bay Area native, love everything you do.
I think you just performed a federal offense to that coin.
It's a stunt coin, it's fine 😂
That’s not true.
@@grntitan1It is a federal offence to deface your currency (18 U.S.C. 331)
Correct, but unlikely to be prosecuted as it was not carried out for fraudulent intent.
Ther is NO law against destroying currency. Defacing to misrepresent is the felony. Once it’s your money, you can do whatever you want to it except try to make it a different denomination. I actually went through all the comments to find this because I knew someone was gonna say it.
I absolutely love all of your precision/machining videos.
Now that you can make precise micro holes, now it’s time to make a micro vise to hold the micro parts in the micro milling machine you now have. You will need to make a micro box to hold and organize the micro holding tools… maybe it’s time to make a scale model of your shop to put the tool in… I can see how this can get out of controll.
I love that you're moving more and more towards the metric system. I don't have any of it, but it feels so right.
The mechanical engineer in me enjoys hearing about the precision of the drill press, but the obvious shakiness and movement of your work table has me rolling my eyes?!
It’s not only the table. The floor in the shop is made of plywood. Not exactly the most rigid floor material. The wobbly phone stand doesn’t help either 😂
3:14 ... We have no idea what your talking about but *HOLY CRAP!!!*
9:36 ... nice.
Converting an imperial measurement of 5/1000ths to a FRACTIONAL metric measurement of 1/8mm kinda misses the point of metric and I’m not sure he was being ironic. 😔
My father had a DuMore that he used in his gunsmithing. My go-to device for this kind of work is a Unimat SL1000.
To much leverage on the handle for me lol now it needs a work light
You continue to amaze me with your skills. Really miss your show. You have some nice toys.
Adam: "One eighth of a millimeter..." Me: "@&$#%!"
I bought a used Dumore drill from eBay after watching your videos. I also have a 100W Raycus fiber laser that drills way smaller holes in metal.
"That's one-eighth of a millimeter for those Metric inclined ..." That's adorable! As if Metric uses weird fractions of millimeters 😀
The ratio of knowledge vs accuracy in his explanations is outstanding in its variety.
I've never heard anyone speak so confidently while being completely wrong ever.
@Albuerum, in my experience as an Electronics Engineer, I found that my Mechanical counterparts and our machinists use fractions of millimeters all the time. It takes time to get used to. And yep, it is still annoying to me 😅
Them: "One tenth"..
Me: "...of a meter? A millimeter, a micrometer?"
Them: "One tenth of a millimeter, of course!"
Me: "Well obviously. So, you mean 100 micrometers, right?".
Them: "Sure".
I don't see the benefit of not using an absolute number instead of a fractional and implicit expression.
@@mstjerning8919 My 4 year old understands math is a fundamental law of engineering. I'm not hiring a engineer that can't adopt or evolve or even comprehend the difference between the metric and imperial system of measurement, and worst of all steadfastly refuses to learn anything or adapt.
@@jasonpowley4913 good for you. That was not my point at all. I can do fractions just fine. My point was about communicating clearly.

I worked as a land surveyor for 16 years. I'm good at knowing distance. You are working at a distance I've never dealt with. I wish I would have gotten a chance to work with you Adam.🤠
Love the care for the video production among everything else. The step beats to music at 10:50 is just charming haha
Kudos to the team!
Holy crow man am I the only one has binge watched every episode and now regularly watch Adam here on UA-cam
That drill press is simply beautiful
Beautiful, thank you all
We had a production lines that had to drill small holes: smallest being 0.0065 inch: six and half thou: those drill break if you sneeze at them. But we didn't have anything like that x-y table. Nice machine. I'd have thought a wooden box to house the press would be nice and it could fold open revealing small compartments holding all the fine tooling you need for a such a thing. Because for me, the issue would be that all of that is very delicate and you'd want to be able to put it away where it's protected from harm and tool loss.
