- Adam tests the precision of his mini Dumore drill with a set of the tiniest drill bits he's ever used. After machining an acrylic base and a brass clamping system to use with the drill press's X-Y table, he tries his hand at drilling a grid of tiny holes evenly across the face of a quarter!

Looks like Dumore's "Precision Micro Drill Series 27"
I've found several pictures and catalog pictures of that drill press (actually a model 27-021) with that X Y table with the hole grid and the Starrett gauges.
but TH-cam isn't letting me post any links. If I stick a link in the comment and post it, YT deletes the comment.

If you are searching on the Internet and can't find what you are looking for try startpage, it's way better than Google. There is no artificial ranking
@@TheRealUncleFrank That happened to me with Adam's last post related to this tool. I own one that is more complete than his, including the manual. The ways of YT are mysterious...
Pls build a self charging while moving e-bike. I know if its possible there is one person can do it on this planet.
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 think he used WD40.
you can easily edm drill 0.004" or 0.10mm. at 2mm deep your looking at < 3min, but the machines aren't cheap.
To commemorate the Dumore setup you should consider embedding the drilled quarter as a medallion in the base… reminders and memories!
Like the mast stepping ceremony on a boat or ship... or the time capsule in the corner stone of a new building.
A million times this
Love that
I had that exact same thought.
cut the pocket to hold the quarter a little big and epoxy it in
“The internet is not a compendium of human knowledge, but the index” is such a great quote.
Can't wait for the followup to this video titled "The biggest hole Adam Savage has ever machined!"... wait, that would be Jamie's. lmao
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.
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.
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
For real dude. I got my grandpas model trains when I was 12, and I learned so much from watching Adam. From calculating scale, to weathering.
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.
This is a myth but it has been passed around for decades. Once it's a Swiss watch maker and on and on. It's fake.
My dad tells the same story, but an American sent the bit to a Japanese shop lol
Yea and my dad said your dad..🤣🤣🤣
There are few things on yt that brings me as much joy as Adam Savage exalted over a piece of beautiful mechanical wonder.
I'm turning 30 years old this year,and I've been working at a hardware store for over 8 years......reason why I could cover three departments today is,I think,because I watch nerdy stuff like this. I really do love "knowing things" and I'll never stop learning....I learned that brass doesn't mess with (like the clamps you used here) other metals that you're working with,so.....just,thank you for posting the nerdy stuff,Mr.Savage. Thank you so much....makers who are in a rut like myself watch you to remember why we keep doing this stuff,and just thank you for posting videos. You are Golden for being a Teacher,and sharing your Process in your personal time after Mythbusters,because it just really means a hells of a lot for all of the makers out there. You are a Gods-sent Maker.
Thank you so much.
You know Adam, I watched you on Mythbusters as a kid and was in awe of all the big weird experiments, explosions, and general shenanigans. Now I watch your youtube channel as a 35 year old man and a 10-years-deep professional CNC Machinist and hobbyist maker. I'm so fortunate that as I have grown and matured, your content has scaled back from flashy high-production chaos to modest and intimate machining projects and tool nerdery. It perfectly morphed to keep my attention and engagement. You do beautiful work, and I appreciate you very much. Keep being you
That drill press is a thing of beauty! As for the drill bits, I can't even think of bits that small without breaking one. Bravo!
I know it's a courtesy that probably couldn't be helped (and that's a good thing), but you really don't have to apologize for occasionally forgetting to capture a build given the wealth of demonstrations and knowledge you continue to share. I can't speak for everyone, but I am more than appreciative.
it is wild how people feel entitled to content
Agreed but it's perhaps because it's a channel that's very much a commercial product than one from a random guy passing on info altruisticly? @@lil-j-waters
I tend to think we just need our fix. Let's face it, we are probably guilty of binge watching "How it's Made" and become drooling idiots watching stuff getting built.
@@tombryant5029 yeah, but there’s so much content out there that no one creator is letting anyone down if they slow down or stop
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 🙂
Now THAT is a flex.
Reminds me of a friend’s dad who worked at a factory making medical equipment, they had a company try to flex on them by sending them a really small surgical needle that they claimed was the smallest in the world. They then sent the needle back to them with their own needle inside it 😂
I remember an old story about the Swiss and the Germans. The Germans made a piece of wire that they claimed was the thinest wire in the world. The Swiss asked to see it so the Germans sent it to them. They drilled 3 holes in it and sent it back.
A variant of the "drilled wire" myth. See Snopes.
@@keithnewton5508Drilled the long axis. That's the way my Dad told it.
Alec Steele has an excellent video repairing a Bridgeport that really delves into backlash and the split nut arrangement on the lead screw that Adam mentioned.
That explains why I knew what he was talking about. Haha.
Ditto This Old Tony - including how the recirculating ball bearings work on these nuts holding the screws.
That kid is super smart
The amount of things i have learned from adam over the decade or more is pretty astonishing... way more than i ever learned at school.... thanks adam 👍
Mr, Savage:
your infectious joy at finding excellence in machine design is a delight.
fixing mechanical thingies is so satisfying! i recently started the hobby of fixing old cameras, and it is so incredibly satisfying to take them apart, clean and lubricate the mechanisms, adjust snd out together everything! As a bonus, you can take incredible photos with a camera that would maybe never have taken a picture again otherwise =)
*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
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.
Adam is the point where creativity and practicallity overlap in a very efficient and soothing way
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
Yet another incredible entry in Adam’s Masterclass on Shop Management. I would spend all day in that shop without food or drink and be in complete heaven 🤤
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.
Im so happy Adam has youtube so we can watch his chaotic energy as a living journal for such a creative fun mind 😊
10:18 At this point I get the distinct impression that zero drawings were made for this build 😂
I have never been more excited about a drill press it’s perfect for the things I build
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
Love watching him drill a tight little hole
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!
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.
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'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.
I've been looking for one of these drill presses for ages. So pretty and would be perfect for the Model Railways/locomotives I build in UK 1:148 scale; I'll have to try and track one down. I already have the drill bits Adam uses, but even my steady hand with a vice drill or dremel has broken 6x 0.2mm bits so far 😂
I REALLY hope you mean 1:48 scale!?
@@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
@@sachacase but ehmmm... why does my Fleischmann N-scale tells me 1:160??
@@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
Have you tried the drill stand attachment for Dremel?
The Dumore drill press has been a long time favorite of mine. Perfect for jewelry. Love seeing you work with it Adam!
Those “Clamps” are R2-D2 foot parts! You can’t fool us!!!
lol.
Love this video. Thank you!
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
Please put that quarter into circulation, it would be interesting to see if someone ends up with it that watched this video
I love those moments of incorporating a new piece of equipment in my shop. Ideas, making, proving concept, improving, all so relaxing and enjoyable.
Wow, Adam Savage moved to tears (almost) by this find and acquisition. I can totally relate! What a great, unique and prescious tool!
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.
Drake took this as a challenge 😂
Underrated comment
I absolutely love all of your precision/machining videos.
I use to drill a lot of holes back in the day. Then I got old.
Giggity
Now you are just poking 😂
I'm only 43yrs but yeah had my fair share, only recently drilled the wrong hole...
thank goodness it didn't break but I'm not allowed anymore!
😂😂👍
They got blue pills to fix that
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.
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
It's somehow just so relaxing watching Adam Savage just Svagaeing around in his "little" shop :P
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.
Holy crow man am I the only one has binge watched every episode and now regularly watch Adam here on TH-cam
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.
I am delighted that you have found that Dumore! Worked with machinists most of my professional life.
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!
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!
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 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.🤠
Dude is so giddy and nerding out about the tools and I'm all in for it.
The followup to this video should be titled "The biggest hole Adam Savage has ever machined!"... wait, that would be Jamie's. lmao
Adam, I am falling down laughing.🤣 I was watching TH-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!👍
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!
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.
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 ❤👍🏻
its amazing to hear the motor labor with a .010 bit. so much torque going through such a small rod....
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.
There was a old Modern machinist book where two competitors who make drill bits got into a competition with each other. company A made a .003 drill and sent it to company B to show it off. Company B drilled a .0015 hole in the shank of the drill bit and sent it back to company A.
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)
Holes that small placed with such precision are amazingly satisfying!
I had a sack of .030 drill bits for unclogging MIG welding tips.
I don't get envious that often but that is a nice machine.
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
The beautiful thing is that it's TAX DEDUCTIBLE!!!
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.
20:27 perfectly describes why LLM AI answers from the Internet will never be as useful as a competent search engine.
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
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.
"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.
You continue to amaze me with your skills. Really miss your show. You have some nice toys.
Phrasing
_"Seriously... Are we not doing 'phrasing' anymore?!?"_
*Such* a great show! 🤣
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 😂
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.
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’ve broken so many 0.1mm bits hand drilling into [very small] models for fiber optics. Getting a drill press helped a lot, but even then I’ve gone through a bunch. Pretty amazing to get through a quarter with one about the same size.
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.
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.
To much leverage on the handle for me lol now it needs a work light
My favorite part of every "One day build" video.
Adam hits a problem,
Scratches his head and then runs off and is seen searching through the whole workshop and comes back with some random device pulled from nowhere that was specifically made for said problem
Classic 👍🏾👍🏾👍🏾👍🏾.
Adam: "One eighth of a millimeter..." Me: "@&$#%!"
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….
Don’t apologize Adam, your videos are super interesting!
Man I love the tools you find. As a machinist I'm always looking to learn new things.
Two 18 wheelers vaporizing a car. You cant keep up with your mind as its' racing. Thanx for being. Totally enjoying your vids.
he is so excited he cant express it in words
As a man with 35 years' experience building VERY tight tolerance plastic injection tooling, I track with you 100%. That Dumore drill press is a rare jewel indeed! I used to have to run .010 inch and .020 inch drills 3-6 inches deep into graphite for the "flushing" on sinker EDM machines. There is SO MUCH feel involved that it is a skill that while in CAN be taught, it can NOT be mastered unless you genuinely understand what is going on. I miss having a job as rewarding (and challenging) as working in tool and die. Using dial indicators graduated in .0001 inch increments with gauge blocks stacked on a granite surface plate to make sure you aren't screwing up. Good old days! Take the "leverage multiplier" off when using smaller drills like the .010 inch, you will be able to "feel" what is happening before you break more bits. 😉Is it legal to do that to a quarter??? 😂 🤔 I am the guy you needed to "find ON the internet" for these kinds of things! It is fun to watch you geek out on this stuff like I used to back in the 90's when I was getting my career started.
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.
Beautiful, thank you all
When he said "Oak Box" I then mindlessly repeated his tambour, AND THEN HE REPEATED HIS TAMBOUR!!!
He's so manic sometimes. I love it.
Adam, today I bought the identical drill press! Mine has other features or attachments that yours seems to be missing. I also found Dumore literature that proves that our drill presses were indeed made by Dumore!
Very nice, Adam. A good sensitive drill press is one of my dream tools. On a side note, if the drill bits you are using are carbide, using diamond hones to create flats and reliefs, the remaining conical stub can be made into a very nice micro graver for hand turning tiny things, and will turn un-annealed music wire.
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.
Great video! I had the opportunity to try and drill some very tiny diameter holes in aluminum. The hole depth was .010”-.015”. The drill was a high speed steel bit. The flute length was .020”= and the shank was 1mm diameter. The cutting diameter of the drill was .005”. The drills were Swiss made. I tried carbide drills similar to the style you used in this video, but mine were only .050” flute length. Never made a hole as the carbide as the drill would snap off only .008” deep into the part. I was using a super precision sensitive drill chuck mounted into my milling machine, maxed out at 4,200 rpm. The .005” hole broke into a 1/8” hole from the other end. Luckily the engineer only needed one sample part for testing. After testing he found out we actually could use a .020” diameter drill to obtain the proper flow of air. It doesn’t take long to learn not to use air to blow chips from the drill………….
Hey Adam, I have a bit of experience with little drills and I'd like to share a little with you.
I/we use them all the time at my workplace. We machine implants, bone screws, stuff like that.
We specifically use little drills and endmills on bone screws to machine the drive feature. It's all CNC, specifically Star Screw Machines, which uses an oil based coolant. Usually we machine a big variation of different size Torx drives on the screws, and you'd be surprised how many different types of screws exist for the medical field! The smallest drill and endmill combo I've used is .016 inch.
We run them in specialty high speed holders, (NSK High Speed Holders).
The .020 Endmill usually runs 20,000 RPM and the .020 drill 10,000 RPM. They're moving!
The story though, and a bit of a caution sign per say, is this.
Sometimes the machines will alarm out at a weird spots in the programs, even though we have safety locks on all the doors, that won't let you open them until everything in the machine stops moving, those little NSK Holders will still be booking it. It happened to me one day.
I opened the door, started checking the tools for wear and any chips, and I felt a little tugging on my forearm. I looked down and the little drill was drilling away, in my arm! You don't feel it, I didn't feel it go in, the motors are so quiet, you can't hear them, I only felt the tugging from my arm moving and the drill kinda keeping that section of flesh stationary, (if it had been the Endmill, that would have been a different story). Luckily though it was the drill, and much like your drills in the video, the flutes were around 3/8 of an inch long.
I simply pulled my arm away, and never felt much of anything, not even a pen prick worth of blood. I cleaned it with alcohol and changed the tool. All was well. Lol.
Just be careful with these little things, I think you kinda wanted to get the chip off of the first drill with your fingers before it flew off on its own. I would advise against that in the future! Haha.
