SNS 210: Acme Nut Threading

[@arkansas1336]

To anyone reading this, Adam is one of the best machinists in the nation, follow along and enjoy his content, fascinating work. This is a great SNS. It's very enjoyable watching you work! ....13

[@zumbazumba1]

Any CNC machine is better than him.

[@georgeswindolljr.4618]

That's debateable, but for you to say that must mean you are jealous of his skills and accomplishments!!

[@zumbazumba1]

looks like you people never machined anything in life.Cnc machines(real ones not chinese mini craps) are amazing and can produce consistant tolerances(due to stepper motors ,no backlash and consistant adjustment of position via digital readout),and they are faster than humans ever will be.Complex shapes are no problem for cnc machine,you need hour of setup to cut a helix spiral on a manual milling machine-on cnc machine you enter program and it cuts it super fast. Adam is talented machinist but its a old dying technology.Industrial production killed blacksmiths,CNC machines ,3D printers and robots will be the end of manual machining.

[@Lokisword]

Love it.. The start of SNS is like a machinist anonymous meeting, Hi I'm Adam. I'm a machinist. Its been 2 days since I used a lathe..... Awesome work as usual Adam.

[@dalejones4186]

Always amazed at how fast you can set a 4 jaw chuck. Shows your experience. Great video.

[@SteveEsp3]

Thumbs up brother, I'm not a machinist, never even seen an industrial machine in person but I can not get enough of this channel.

[@rakaiser7331]

I am a retired Machine Repairman. I was around machinist for over forty years. I have never seen someone zero in a part in the four jaw as fast as you can. Wasn't there a competition in one of your videos where you won. I really like your videos, they bring back great memories. I love your attention to detail, in everything you do.

[@ronaldpittman1307]

WELL THE ONLY WAY TO DO SOMETHING IS DO IT THE RIGHT WAY AND WE HAVE A MAN THAT IS VERY GOOD AT WHAT HE DOES GOOD JOB

[@jefftaylor7511]

If either you or Keith Fenner had been my HS shop teacher I would have spent my life as a machinist. Great teachers - both of you.

[@magnusnielsen2648]

Adam Booth, the most reliable guy ever :) i can count on him having a video ready for me every saturday!Thank you man!

[@blue-runner]

one of the first machine tools I learned to use, along with planner way back when.. Been a machinist 40+ years. Love your videos.

[@WeaselJuice]

Incredible tolerances! Really enjoyed this repair series and I learned a lot! This is truly a master machinist at work.

[@tommytulpe3926]

Hi Adam, it's nice to see the joy in your face. Looks like a boy with a new toy. Greetings from Germany.

[@FreezinFury]

When i was 19 some 28 years ago my first real job in a workshop in the UK was to watch and learn under this guy was a time served turner. They wanted me to learn the proper way so my task was to strip a old Dean smith and grace Lathe and make replacement bushes for all the feed/screwing slides out of phosphor bronze .It was reall enjoyable time i learnt press fits and how to feel if the fit was right for the bush . I love watching vids like this and thinking back to that time.. Not many skilled turners left now . Eventually i graduated on the CNC .

[@365hillclimb]

I'm really glad I'm not the only one who feels that satisfied when a job turns out well.

[@ringo_98]

Hey Adam, great work! Thank you for your inspiring content, you got a very young austrian fan right here !

[@jeffryblackmon4846]

I AM enjoying your Acme threading videos. I have learned a lot. Your comments at every stage were very helpful to understanding what's going on. This is an excellent presentation.

[@JohnCasale]

Love sns!! Just picked up my first mill today after being inspired by your videos. Can't wait to re-watch and learn more!

[@kjamison5951]

You say "It works!" and then you smile as if you weren't expecting it to work. I do that too. Your confidence is in the skill you possess, but you still get a little thrill each time! Kudos!

[@phlodel]

People that really know what they're doing aren't afraid to make mistakes and are willing to admit it. That's how you learn to really know what you're doing.

[@georgeswindolljr.4618]

Experience is the best teacher, AND THERE IS NO SUBSTITUTE!!!!

[@jlucasound]

You did it! Nothing more satisfying than rebuilding your own machine tools. Excellent job Adam!

[@DonnyDarko13]

Yes, but eben you didn't enjoy that free moving in your Workshop you cant do this😭.

[@roderickwhitehead]

Great stuff as usual, Adam! Love that "$4000 smile" right at the end. I was doing the exact same thing.

[@MikeLike8]

I learned the importance of Acme threads literally 30 years ago as an industrial mechanical draftsman by detailing specifications on a the column ends of a 34” diameter shaft for a 4 column 20 ton hydraulic press that was massive. The loads could not be taken by smaller tooth profiles. The teeth n the thread form were giant. Thanks for the great videos as it is helping me with my bench lathe work practices.

[@ypop417]

The Loony Toons Gang Is happy to see Acme Threading LOL

[@rayfalcoa1955]

I see where you have done this many times......very nice video, it was a pleasure to watch....thank you.

[@greggoff4990]

Thank you for an hour+ of guaranteed entertainment every week

[@AaronBelknap]

I think threading is an art you have mastered, thank you for the whole tamale in showing us how you arrived to tool height, depth of cut, pitch, angle etc. Very cool process and I think I'm understanding how you do it with the wheel when you start the cut. Thanks again for your video's and explaining the process!

[@CAOFPSA]

With the uneven wear on the length of the shaft and areas where it's bent or 'twisted', and even demonstrated that the nut binds trying to thread through the length, I still can't help but feel a new shaft would be the best way to go. All of the work taking the slide apart, making a new nut, making thrust washers...and using the old messed up shaft?

[@MrJimmyPayne]

Been watching your channel for about a year now. Already have 2 trades boilermaker and welder. You have inspired me to take machining as a third trade. Thanks Uncle Abom!!

[@HammerPowered]

I've really enjoyed watching the G&E videos, man. Watching the machine get cleaned up and ready to go back into useful service has been a neat transition. Looks like many more good years will come from it as a result.

[@rafaelreina6364]

To see the Monarch back... that is a real gift!!!

[@Mitchiedean]

Haha that intro. I felt like I was at an AA meeting. Lol. "Hello, My name is Adam, and I'm a machine-aholic"

[@GuyonaMoose]

I haven’t touched a lathe in three years, And let me tell you how much miss throwing chips. Your videos are great and a wealth of knowledge. Keep it up.

[@johnferguson7235]

All I can say is that you've gone nuts Abom, ACME NUTS. GIVE THE GUY A THUMBS UP ... cuz, man he earned it.

[@rizwanyoutube4542]

I am a lease machine prater watching your video helped me to fix a small error

[@nickhorton5839]

Adam, Love your show brother. Thank you for keeping me in the shop, keep up the 2018 personal goals! I can see the effort.

[@sgermain06]

This is awesome! I really like how much more confident you are now that you were when you started, where you barely looked at the camera. You seem so much more comfortable! Keep up the good work and love watching your videos!

[@RyanWeishalla]

Great to watch video. The Monarch looks like it was a very thought out machine with a lot of different capabilities added to it.

[@ThomasEJensen_TEJ]

Hi Adam. I feel that you earned the right to add Filmmaker to your title. And as usual thanks for some good content. I always enjoy watching you beat that metal into submission. Keep it up buddy, and thanks. :-)

[@ccamen]

And a Grill Master and lover of women and wine :)

[@JRD77VET]

Nice work and thanks for the unique info on the Monarch "lock". I've had my Monarch CK for about 6 years now and never knew that. Just proof that a machinist can always learn something new. Thanks, Jeff Also, take notice on how he held the emery under power. FINGERTIPS ONLY. That way if it grabs, it just comes out of his grasp without injury.

[@JRD77VET]

Just checked out my Monarch CK 12 and I get about 2-1/2 turns of the cross slide between locks. Is that right?

[@TheMetalButcher]

Sounds correct.

[@Abom79]

Yes that’s right

[@stevencoldiron3335]

WHAM!!!!! Home Run... I was on the edge of my seat with this one. Is this cool or what, Great job Adam

[@dragman377]

Made a screw and nut for a civil war re-production cannon a while back out of brass. Had to make the nut again. The first one was way to loose. Good job Abom. Thanks again for the video.

[@briscoedarling3237]

From where I sit you are much more than a machinist sir. I would describe you as a Master Craftsman. Thanks for showing us armchair admirers your skills.

[@jimmilne19]

Very instructive being able to see you (your hands) operating the lathe. Your explanation was also very useful, too. Thanks for sharing.

[@customknife1]

Adam: Watched a lot of your videos. Grew up in Detroit where machine shops everywhere but they remained a mystery. While I may not understand all of your demonstrations, I enjoy them non the less. You have a nice video touch. Well done.

[@gordonagent7037]

Hey Adam another great job. I love the sound of that old Monarch lathe of yours, she's a real classy lady

[@ls2005019227]

I am thoroughly LOVING your G&E improvement series! It may be that I understand & appreciate the satisfaction from using a machine that you've invested time to bring back to life. The nut you made was a big improvement, although I know you were shooting for zero backlash. I'm interested in how you'll improve on that, without making a new leadscrew or straightening/chasing your existing one. Thanks again, looking forward to more!

[@jlucasound]

That mini surface plate is priceless. Tom Lipton, Jim Stamper, Awesome men. You too, Adam!! :-)

[@BasementShopGuy]

Hey Adam - I liked this one. And knowing what I know about restorations and machine rebuilds, that difference of backlash along the length is all from wear in the screw. The nut is perfect - great job.

[@CllAslnr]

I enjoy watching and watching your work. thank you so much.

[@gjkozy]

I enjoy your videos and have been impressed with your skill and the machines you operate with old timer deftness.

[@smartypants5036]

Nice machining. The Monarch is a lovely machine. Good operator to boot.

[@januarioqueiroz3122]

You are a great professional and a humble person. God bless you!

[@mrblack61]

This comes at just the right time for me. Ive screws and nuts to make or a lathe im working on so nice to see the work and important points involved. Cheers Adam

[@normanmoore]

Hi Adam just to let you know I am fascinated by your KZbin videos as a retired motor engineer from the UK I really enjoy your channel keep it up cheers.

[@mikemckelvey4738]

Adam, prior to the start of this SNS, a regular commercial appeared. You’ve made the Big Time! Very happy for your success and I love watching your videos.

[@RollingEasy]

Beautiful.... I did exactly the same just a couple of days ago with an 8TPI on .800/.675 and know the feeling you have when it hand screws like thick honey without a hint of grab or backlash. I really like your style and how you do things and the set up of your shop. A true craftsman. Thanks for all your videos and I'm guessing your building project is all up and running by now.

[@stxrynn]

That Monarch is a well thought out machine. My old LeBlond could do with a positive stop for threading. I've seen something that fits on the dovetail, I guess I need to build that now!! Thanks for keeping us updated on the project. Good stuff.

[@MikeBramm]

Nice work, especially for not having cut an acme thread in a while. You make it look so easy.

[@IBWatchinUrVids]

Mr. Bom - (Can I call you that?) I bought a 3d printer years ago, and it has become part of my regular tool set. It took me a while to find uses for it, but, pretty much anywhere you look in my shop, there's something printed. Caps, plugs, adapters, shims, hooks, etc. It's not metal, but you can definitely make useful items, and the best part is, once you're fluent in it, you can design a model, press go, and walk away. Next thing you know, there's your complete part. Very worth the time and money, in my opinion.

[@mikenixon9164]

I thought for sure you would make a new screw too match. Nice video Adam.

[@RobertKohut]

Nice!! Absolutely top notch content, videography, commentary and photography. You absolutely nail it!!

[@gordonsmith8400]

Nice job Adam really like the shop job projects.

[@3dwildcat822]

That's great that you what to get into 3D printing! That's the majority of what I watch on KZbin, I even have a 3D printer myself. But I recommend looking through the suggestions of people on KZbin for the best machine for you. There are a lot of printers that you could choose from, there are a lot of cheep ones, but you said you want good one, and there is a number of pretty good ones that aren't super expensive. I know that a lot of people with your skills and knowledge tend to get into 3D printing with a LulzBot 3D printer.

[@stevenkimball5592]

Big man you better keep them videos coming bro. I sit in my RV watchin the fabulous work you do wishing I could be there helping out, but oh well!

[@ChrisBrown-dy8ts]

When the screw goes in but it’s tight, leave screw in the nut then remove from chuck and using a “soft “ hammer , hit all way round the outside of nut , it will free it off perfectly. I make acme a lot and sometimes 2start acme.

[@leslieedwards2558]

once again Adam you have excelled yourself that was a fantastic video you have a very clever brain and hands looking forward to the re-building of the Shaper

[@danielbuck]

Fantastic! Inspirational and educational. Thanks again :-D And I think it's awesom that Tom sent you a plate :-D

[@ShaneBurrell1]

Great video!! Thanks for showing the SPI gage. I hadn't seen one but its something I've needed so I ordered one.

[@danielwerger5641]

Adam, keep the shaper stuff coming.... Love every second of it....! Cheers from Vancouver, Canada... ;-)

[@stevegardner9258]

I've been hanging around KZbin today waiting for this one.

[@kentuckytrapper780]

I love that monarch lathe, I've got one but mine don't have all the extras I have a model A late 1800s lol,great video, keep'um coming

[@fritzdoerring9058]

As a teen ager, I was employed to operate a lathe setup as a screw machine cutting square threads on a screw as reduction gearing on a hoist of haevy material. I loved that job; seeing a hunk if steel transformed into a useful instrument.

[@JRock17991]

Perfect Timing! Thanks for sharing this. I'm super green to machining, and building a Milling attachment for my lathe. My intention is the leadscrew will be Acme thread. This really helps me get a handle on how to go about that.

[@ChrisB257]

That ductile iron makes super nice chips. I've had that effect where last thread has a bit of tightness. Other thing of course is the wear difference over the length of the leadscrew. Nice work as usual.

[@michaeljohnson8342]

Hey thank you for the videos. While I am not a machinist, I do work on airplanes and love the close tolerances you provide! Mike

[@AceNos71]

Another great episode of SNS, thank´s Adam!

[@juhanir8698]

👍 A realy nice video and great success for you with the threading of the acme! As always all your sns parts are that interresting to follow and very entertaining and learning. Your shaper will be that accurate and precise tool for your shop after this real thorough overhaul. Kepp up with the always great skill and spirit! Thanks for sharing👍

[@aaronholmes8568]

YAY!!! SATURDAY NIGHT SPECIAL TIME! Hi from Ireland!

[@KingofStone3]

I didn't think I would view the whole video, but you made interesting. Great job and keep them coming.

[@SmartShocks]

Thanks Adam. I have wanted to understand the specifics of ACME threading so that I can build my own CNC plasma table for a reasonable price for a long time. Thanks for teachings.

[@tattoos1988]

I’m here from Keith Rucker glad I subscribed great videos ABOM looking forward to watching your other videos thanks

[@SuperKingslaw]

Nice work Adam!

[@szabib2144]

The knowledge that goes into using a cnc lathe is amazing, wish I would of been better at math. Great video

[@picklerix6162]

Acme threads are usually some of the easiest threads to make on a lathe. The oil field API tapered threads are more challenging. I was lucky to work with some great machinists who showed me how to set up the taper attachment correctly.

[@darkdelta]

Another great video, thanks for letting us look over your shoulder. Great camera work!

[@Wobblybob2004]

Next project, a stand for that surface plate! :-)

[@aussiebloke609]

When you started with "My name's Adam, and I'm a machinist"...I was waiting for a group of people to chorus in unison "Hello, Adam"...kinda like you'd expect at an AA meeting. LOL

[@ZEROSTATIC72]

My thoughts too, :)

[@KohalaIronWorksCase]

Paying close attention to your threading videos & ohers. My South Bend Heavy 10 is almost up & running. Threading is what I wanted to get into....among other things. Making my own tools is something else I want to do with my retirement years up ahead of me. Make stuff I couldn't afford to buy. Mahalo nunui for sharing your knowledge. Aloha, Chief #988

[@Imwright720]

I don’t know why but there’s something about a spinning piece of metal getting cut by another piece of metal that’s relaxing. Especially when you get those little metal ribbons. I don’t like ductile iron, no little metal ribbons. Ok, I saw a couple small ribbons.

[@TheQuantumFire]

Hey Adam, have you thought about re making the acme screw as well? You said it was worn more in the middle than the ends, so why not remake one and that way you cant match the nut to it?

[@donzmilky5961]

Quantum Fire its a really long part, kind of hard to hold tolerance and properly support it would be my guess. Even with one of those triple roller bearing supports.

[@noelhenderson700]

You would use a follow rest with two supports for that job. It is mounted on the carriage and supports the work on the opposite side of the tool. It would be relatively simple to hold tolerances with a follow rest.

[@ricklane9135]

Great work as usual....

[@ericreynolds74]

What would be cool, when shooting the shot of cutting the internal threads, is a picture in picture...or even multiple screens, the main view being the chuck rotating, but then on the mini screens within the pic looking down at the dials so we can see .020 then .040 etc, maybe one of the thread cutting gauge . I'll take a t shirt lol

[@spagamoto]

Did I hear 3d printer? If you haven't already, consider a Prusa i3 Mk3! Used the Mk2 for a while and loved it so much I got a brand new Mk3. The little upgrades and that awesome spring steel print surface are great.

[@hilltopmachineworks2131]

I reached out to Tom and ordered one of those little granite surface plates.

[@Wulferious]

Superb video, as usual. Just as an idea: You could ask to send that shaft over to Keith Fenner to get that warble taken out! Nice little hand-shake between your two channels again. I've seen the magic he can do to propeller shafts, he should be able to make that screw as straight as an arrow. Cheers!

[@THUNDER-on2xo]

I Know you won't but don't forget to notch for the holding Pin. Awesome Job Adam !! You Rock Brother!!

[@BerndFelsche]

It will be interesting to see what this does for the judder at the start of the cuts on the G&E

[@mikewhite255]

Put some lapping compound on the tight spots and work the nut back and forth over it it will just eek out the tightness and leave a very close tolerance. I like 500 grit. Not a machinist but ive battled plenty a bad thread and this works excellent.

[@peterfitzpatrick7032]

Mike... the biggest problem with that is making 100% sure you get all the compound cleaned outta there, easier said than done, if it beds into the durabar you're f#$%ed... it'll wear in short order...☹️

[@EquitySolutionRayRaz]

I love the beginning of this video , “ my name is Adam and I am a machinist “ hahah is almost an AA meeting speech at first , like obviously there is an addiction here to machining hehehe , I am going to hopefully pick up a decent Logan lath with tooling for 625 , I been looking into them and seems like the right fit for my basement , especially for my budget

[@billmilton1287]

I enjoy watching you that I'm really impressed how you do things ll

[@gohuskies583]

Nice work Adam. I was sharing your joy of success when it turned out well! Thanks for the video.

[@jeffpierce8115]

A 3d printer can be an asset for certain uses and using the correct type of filament. I have a craftsman 101, Atlas 618, lathe my dad bought used in the mid 60's. The cross feed backlash was around .019". I have never got around making a new nut. It is 1/4" 10tpi stubby acme LH. I got a cheap Chinese 3d printer for other reasons. I said Hmmm, broke out FreeCad and designed and cross feed nut. It took a couple of tries using abs to get a good fit do to printer tolerances. they were to tight, so I just slit them length wise and saw where it was binding. The acme thread is not cut with any tool, used as printed. The only tool cutting was to tap the 10-24 thread for the saddle attachment screw. Third try was perfect, slightly tight, but still turned easily. I then got some NylonX, carbon fiber impregnated nylon, for anther project and printed one using it. Worked great. Backlash is now .004", and most of that is in the shaft back and forth play. Need to shim that out I guess. I have been it using now for almost a year with no noticeable change do to wear. If it does start wearing to badly, just print another one. If anyone is interested, I posted the stl and Freecad drawing files to thingiverse.
