Adam Savage's One Day Builds: Giant Nut and Bolt!

[@tested]

Psssst, we have 98 One Day Builds in our playlist now. Just sayin'. See for yourself: kzbin.info/aero/PLJtitKU0CAej22ZWBqrimPkn0Bbo6ci-r

[@VikasPatel-nl8tb]

Just wondering Adam, is cooling fluid not needed on brass?

[@gaivoron]

Adam, could you consider doing something like a giveaway or a raffle for your fans? I would love to get that bolt and nut for my personal collection. I've been a big fan of mythbusters since the very first episode; therefore, I would have lots of sentimental value for anything that involves you and the crew. Thank you.

Anything special planned for the 100th?

[@ifihaf2]

[@deletedhobo7405]

Okay, but how many actually took a day to do?

[@thethoughtemporium]

Can I just say I'm loving this new format? Like obviously this was a great channel before, but it felt very... produced? I dunno if that makes sense. It felt like something you'd see on discovery. Now it really does feel like a youtube maker channel. Both are great, this just feels more personal. I look forward to more of the old style, but this new style is very fun as well. It's also humbling to see you struggle. After years of watching your stuff it always seemed like you are an expert in everything you do, but seeing you struggle to learn a new skill was great. I'm a little surprised that you're just learning this particular one though. Cutting threads was one of the first things I learned on a lathe, but then again everyone's machining journey is different based on what they want to make. You make so many things effortlessly that I'd find super difficult to machine. All in all, great job!

Adam explaining the portfolio and interview thing and why a project like this is important I feel like was a piece of absolutely priceless advice.

[@honkendahlgren]

I certainly agree it’s good advice. However, what he is creating is pretty far from what he set out to make, as he says himself about 22 min in. But I guess this was also meant to show that “practice makes perfect” and it’s ok to make mistakes and learn from them.

[@bmbunch8825]

Adam, traditionally when machining threads you reduce the depth of cut as you get deeper in the thread. I'm currently turning a 1-1/2 npt on SS and I start with an .0112 pass, and it takes 12 passes with the last pass only being a .0032" pass. This keeps the chip load equal since you're using more of the cutting edge.

[@deckum23]

Also if you set the compound at ~59.5° and feeding in with that cuts on one side of the thread instead of both sides at the same time.

[@kylegoerlitz7392]

@@deckum23 29.5 degrees. adam is not doing that here.

[@jasonjanes9756]

makes sense.

[@ThatBeTheQuestion]

Shouldn't you also start threads by first adding a chamfer to the face you start cutting into rather than cutting into a face perpendicular to the axis? That way you have a gradual introduction to the thread cut and makes it easier to thread the nut on later. It's kind of like how you always chamfer a hole before you tap it or a shaft before you cut it with a die.

My father taught me that when undertaking a car repair (read: undertaking *any* mechanical project.), you MUST observe the proper rituals: 1. Lose or break the proper tools. (Throwing them at the ground is also acceptable here). 2. Recite the proper cuss words in appropriate order, voice and volume. 3. Offer up some of your own blood to the project. (The mechanical deities seem to have a preference for offerings issued forth from the knuckles.). ONLY THEN will you have breathed life into your project. ONLY THEN will it become a functioning mechanism as intended. Good job in this! Loved watching!

[@fristlsat4663]

I enjoyed the portfolio talk where he talked about demonstrating how to make something to external specifications, and then proceeded to do the opposite. That nut and bolt are nothing like the original spec. So in that regard this was a complete failure. As a skill stretcher, and as a nifty piece of desk art this was a great success.

[@nolansprojects2840]

Pierre right, what I have learned is that the best thing you can do on your resume is use technical terms to show you know the subject, and more importantly use numbers and evidence to show things you have done. For example let’s say you’ve made a software the reduced the time it took for employees to document their work. (Can you tell I’m not in IT? 😂) You then could say “created software to decrease employee documentation time by 40% per use” and that gives the new company evidence on what you have/can do. And just make a bunch of points like this. My advice is to document these achievements as you do them, that way you don’t forget such details (something I learned a little too late.)

Right?? There’s an old saying that more or less “the most brilliantly made/engineered items are the ones you never think about based on its simplicity and efficiency”. This nut and bolt are fine examples. They appear to be so straightforward and the method in which you use them is also as such, so you never give it a second though as to how they are so precision crafted and work flawlessly. So you don’t realize how much more impressive and substantial they are than they appear to be at first.

It took me a lot of energy to watch this one day build, because by coincidence I worked as a toolmaker for 20 years of my life. I already saw what mistakes he was about to make, and I wanted to shout "stop!" I was so sorry for him, I wanted to help him all the time. In this way, however, he was able to learn a lot the hard way, just as I had to learn other things, and hopefully will do in the future. Above all, however, you have to learn to deal with failure without giving up. And I admire Adam‘s honest handling of this process. In this video you don't really learn how to cut threads, but how to motivate yourself again and learn to live with compromises. And in the end he was satisfied with his achievements. Thanks for this video!

[@nickhadfield3192]

Right so this will probably be buried, but here's my two cents on why it was grabbing so badly, given on what little I can see of how you're doing it (and it may help other people just learning, and that's what I love about the internet) When you turn a thread, by plunging the tool straight in perpendicularly to the work, the threading tool has to cut on both sides, which will chatter and grab due to cutting forces colliding. Setting the compound slide to 30 degrees from the ways and feeding on that instead of the cross slide means the tool follows one side of the v groove and only cuts on the other edge. If that's what you were doing, I apologise, and hope that this gets to someone who is just starting out. Gorgeous bolt, by the way!

[@Impuritan1]

His main problem with it popping out of the chuck after he decided to use the tail stock is he didn’t drill a deep enough hole, actually it didn’t look like he had drilled one at all, for the live center to do its job.

[@noridawheeler]

Precisely. Also, his order of operations could use a lot of improvement.

[@Ohio_etsu-masu]

This should be up there ☝

[@denny9931]

16:46 and 16:36 super scary. My armchair level advice would be to clamp the piece against a sufficiently tall chuck spider, so the tailstock can provide a lot more pressure against said spider and stabilize the part better. Center height of the tool might also be an issue after reversing it in the holder.

[@photomattmills]

I think the reason Adam had problems work holding when cutting the thread in the bolt was the compound was on the wrong angle. This Old Tony's thread explainer video has a pretty good detailed explanation, but basically if you're cutting threads and have it at the wrong angle (29.5º for standard threads), instead of single point cutting, you end up form cutting, which increases the forces involved by quite a lot. It also looked like swinging the compound correctly would have fixed the tool clearance issue, and given a stiffer setup overall.

[@c4fishfood]

Ya, the setup was not conventional. He started with a triangular insert on the OD threads, rather than a threading tool, which made him use a tool holder with too much stick out and put the post at that funky angle. He didn’t use a center at first, and then after he did it looks like the center wasn’t center driller deep enough to provide significant support... But he got it done!

I guess that's the key insight here: you don't want to be your thread cutting process to turn into a form cutting operation. I think Joe P. once made a nice sketch on his whiteboard on how you "build" your thread in steps so you can keep the cross section that is removed the same in each pass...

You mentioned seeing one's limitations when polishing the brass, I feel your pain. I just hand polished brass through the sequence of 320, 800, 1000, 1500, 2000, and 3000 grit sandpapers against an engineering reference stone to get a flat surface. It was very instructive on how clean one has to keep everything, and how even one's hand pressure needs to be... You may not have enjoyed when things went wrong on this build, but the fact that you did not hide your frustration is both humbling (to me) and a useful reminder that things go wrong no matter who you are. I just had a bad day where things went very wrong, and a person I was dealing with got very insulting. Watching this video helped brighten my day, so thank you.

@@carbon1255 Perhaps I don't know about the traditional brass polishing approaches... Also, I like the effect, it produces a very flat surface if one keeps their hand pressure even (as flat as the surface one polishes against, in my case 0.0005" over an 18" surface), and if one goes a bit further the lines become so fine that they can only be seen under a microscope.

When cutting threads, I was taught to set the compound just under 30° and feed with the compound instead of the cross so you're cutting with just one edge of the tool. This reduces cutting pressure and gives the chip somewhere to go.

Well done! having only achieved hand knurling hammer and bar handles myself, it is a skill. I have known many mechanical geniuses. My wife's father invited the Diamond Knife while working for DuPont in Delaware. In my past as a machine tech I was in their many machine shops. The ones in Wilmington had 6X6 oak beams on end for the floor. Lathes, milling machines bolted down. He was a refugee from Hungary, after the Diamond Knife he worked on other projects. As a moon light job he repaired old electric organs. The kinds that used strings, gongs etc operated by an motors. The greatest machine work I saw finished was a scale model of a WWII P47. It was the fighter flown by a Dupont. He had a real on in hanger in Toughkennon PA. The scale model had fully operating landing gear. I believe it was the first generation that the gear folded up into the wings. He quickly repaired my several MGB's. One afternoon he was winding up a new gas engine for his RC plane flown in the flats of Delaware. My wife's younger sister there with her husband a true idiot. The engine was buzzing to a whine as Steve tweaked it. The guy asked and poked his finger at the invisible whirling propeller. It small version of the scene from Indiana Jones. We all watched as his finger grew shorter. The next summer at a BBQ he got impatient with the slow start to the charcoal. He grabbed the can from his lawn tractor and pored it on the grill. Lucky or not the whole thing went whoosh, his other arm lost hair and the can shot up 50 ft. Everyone ran while he stood stupified as the can came down.

Adam, had this ODB went exactly to plan, with no mistakes had, I honestly believe you wouldn’t have been as happy. The reason I speculate this is like most analytical people, you truly do enjoy learning from your mistakes. For the simple fact that you LEARN from them. Case in point, had you not screwed up (pardon the pun lol) the threads on this project, you might have done it on a mission critical piece that you might have been working on for days. So to see your reactions as you progressed through this build, even though you said you were a lil upset, I could tell by your emotions that you were truly having the time of your life. And to see the end product come out as good as it did, was truly a joy for me to watch! Keep on keeping on good sir and enjoy the process!!!

[@milivojdelic2566]

As someone who actually went to school for machinists (CNC though), and since it was a long time ago i won't be so technical, but you should really not take your workpiece out of the jaws that often. you're gonna mess the center of the piece and your nut is gonna be crooked. Interesting build, nevertheless. Love from Croatia

[@theseewolf8800]

Can confirm.

[@LeoBego]

I would say that it's a matter of keeping your center holes as reference during the lathe work. If you have a center-holes in each face of the cylinder, you can always center the part you are machining by using the tailstock and a dial indicator.

[@cyberslick18]

@@LeoBego Or just don't take the part out constantly lol

[@DJFlorilu]

​@@LeoBego You'll still have some differences though, with hard jaws it can be like 1-2/10 of a millimeter. With soft jaws, which are turned to the diameter of the workpiece, you can get it to 1-3/100 of a millimeter. If you really want to keep tolerances tight, then you should never take out the workpiece at all. If you are just doing lathe work for fun, the center holes will do it. If you are in the engineering industry, like I am, you have to really think about how often you want to take out the workpiece. The more often you take it out and put it back in, the more chances you have to mess it up.

[@bryanshortall787]

A good point. He should also have a dial indicator so he can properly center the workpiece in the chuck each time. Watching several other machining videos, it's normal for it to take quite a long time to tighten the jaws, check the runout, modify the jaws, check runout again, modify, check, etc... until the level of runout is acceptable for the work they're doing. Eyeballing the center once and running with it seems like bad practice once a true center on the workpiece has already been established. Good enough for an artistic bolt, but probably not quite good enough for a machining course. Still a cool project! Always great to see videos that show you the screw-ups as much as the successes. Helps everybody learn!

I am glad that the errors that you found did not injure you or your lathe. I am also glad that you were able to take a step back and breathe and learn from said mistakes. I am always very interested to watch somebody try and learn new things when it comes to machining because I get to look back and remember the mistakes that I made when I was learning and I think that makes me better because I can watch the mistakes over again and remember my own and it kind of just keeps me in check. So thank you for going through this trial and bettering yourself because at the end of the day it better to me as well and I want to thank you for that.

Load program that an engineer wrote.. Load Part. Push button. Get result. That just doesn't have the same impact as manual machining, which is truly an art form.

[@HelloNotMe9999]

Suggestion for a better order of operations to make this way easier: 1. Face both ends (ignoring large hole). 2. Turn to critical dimension for threads, including relief at root of shaft. 3. Cut flats in dividing head. 4. Return to lathe. Cut threads and chamfer end of bolt for easy staring in nut. 5. Turn “junk” nut to protect threads for next step. 6. Reverse part in lathe. Push bottom of bolt head tight against chuck jaws. Part off nut. 7. Chamfer edges of bolt head. Facing cut to clean top. Bolt is now complete. 8. Grip nut in lathe. Facing cut on rough side. Cut internal threads. Slight countersink of hole (for easier starts on bolt). Chamfer edge. 9. Flip nut. Facing cut, countersink, chamfer edge. Nut complete. Similar to what you did, but gives you a lot more material to grip in the chuck jaws while forming the threads. Also means that if mistakes are made, you still end up with matching sizes on the nut and bolt after cleanup of damaged faces.

[@Cinnabuns2009]

Also, for the nut, don't measure the minor diameter of the thread and make your hole that size. Size up 10-20 thousandths at least (depending on diameter). 100% thread sure can be done but no one does it and it just makes your life harder. 75%-80% thread is a good place to shoot for and about what a proper tapped hole is sized for.
