Making a New Lathe Chuck Backplate (from scratch!) for an Atlas Lathe 😁

Sup folks!
Had a few mishaps in my shop and needed a new 4-jaw chuck. Now we're gonna make a new backplate for it! 😃
A big thanks to Harold over ‪@AmateurRedneckWorkshop‬ as well as @Kimberzelik Zelik for the heaping pile-o-stickers 😁. And an extra big thanks to all you awesome subscribers! You make it all worthwhile!
Cheers!

Absolutely brilliant work, and grace under pressure with that center punch save! Smart boy... I'll have to remember that trick. And I got a kick out of every shock take at the stickers... even at the last one, it was still funny. 😂

[@Just1GuyMetalworks]

Thanks man 😊. Glad my efforts at some dry humor weren't wasted 😁. Cheers!

Atlas Lathes - damned by Professionals, but loved by their owners ! My brother and I have made gun parts, car parts, fixed all sorts of around-the-house items that needed a lathe - We jointly have a 6" and a 10" Timken bearing lathes, and they are fantastic !

[@Just1GuyMetalworks]

Hands down the handiest tool I've ever purchased 😁. Cheers!

[@kimber1958]

I got a Big Boy lathe a few months back . Now watch me take it apart and put it back together . I now go by the multi thread starts Czar

[@Just1GuyMetalworks]

I have been dropping in from time to time. You put out a shit ton of videos so I haven't watched them all 🤣. Sure beats the mini lathe I bet! 😁

Hello Chris, A big CONGRATULATIONS on passing the 1,500 milestone... nice work on the backplate and super funny when you opened the machinery handbook and Harold's sticker was there. Take care and don't melt. Cheers Paul,,

[@Just1GuyMetalworks]

Thanks, Paul! 😊 I actually did that a whole bunch of times but unfortunately the clips got lost in editing lol. That's what I get for trying to cram too much into one video 😏. That book has been coming in pretty handy lately 😁. Cheers!

[@bhein67]

Well done! I applaud your problem solving!

[@Just1GuyMetalworks]

Thanks... again 🤣. Cheers!

Gday, great to see your back, that’s a beautiful looking chuck, the back plate turned out spot on, don’t get much better than that, you won’t know ya self now, top job mate, cheers

[@Just1GuyMetalworks]

Thanks, Matty! 😊 It's certainly a step up or two from what I'm used to lol. Cheers!

[@RustyInventions-wz6ir]

Nice job making the spindle thread . The backing plate came out well , good save ! Cheers .

[@Just1GuyMetalworks]

Thanks, Max! 😁 That center punch finally came in handy lol. Cheers!

[@craigtate5930]

Good save on the register with the punch marks, darn clever idea

[@Just1GuyMetalworks]

Thanks, Craig! Really did dodge a bullet on that one lol. Cheers! 😁

[@yvesdesrosiers2396]

Nice to see you back. Cast is self lubricating that is why most don't use lubrication. But there is nothing wrong in using cutting oil it just makes a paste. Hope your truck is working fine now. Cheers and stay safe.

[@Just1GuyMetalworks]

Thanks, Yves 😊. Yes, it apparently has a lot of graphite but I've also read somewhere that lard could be used for things like tapping and such. Oh well, it worked out ok 😏. The truck is running great so far, despite the jb weld on the distributor lol. Cheers! 😁

[@danmooney6881]

I had to make the same backing plate for my atlas lathe. I'm not comfortable doing single point threading, I found a 1 1/2 -8 tap on ebay with shipping for right at $20. I'm hanging on to that! Good video! Dan From Oregon

[@Just1GuyMetalworks]

Nice! That would take one serious tap wrench! 🤣 Thanks, Dan! Cheers! 😁

Four tent's out... To me that's perfect. Nice job and a very well made video.

Thanks, Rusty 😊. It will serve me well. Cheers!

Thanks, Aaron 😊. It would seem I'm missing a few Aussie stickers though 😉. Cheers!

[@Preso58]

I'm so glad you pensioned off that manky old 4 jaw. The new one is so much shinier, and more importantly, not from China! So, it'll probably last more than 5 minutes. God job on the internal thread. Just by coincidence, I did one yesterday using Joe's reverse from a hard stop method.

[@Just1GuyMetalworks]

Yeah, the ol' girl served me well but still may be of some use. I'm thinking weld positioner maybe 😊. Using a new one is taking some getting used to lol. I really like that method of threading although I think my execution of it could use some fine tuning 🤣. Thanks, Preso! Take care, Cheers! 😁

[@theeddies]

Nice job man. Not sure I should be above ARW but I will take it, lol. Congrats on 1500. It's amazes me that something so simple is actually a pretty complex and precision project. I ran into the same kind of time consuming stuff when making my 4 jaw backplate and I did not even have to do the big threads. The displacement idea was certainly a project saver and a good idea. All the best! Eddie

[@Just1GuyMetalworks]

Thanks, man. Yeah I'm glad it worked out too, really didn't wanna do that thread again lol. Cheers! 😊

[@joeybobbie1]

Hey, you got it mounted 👍 great Video.

[@Just1GuyMetalworks]

Thanks, Joey! Cheers! 😁

[@m.m.7511]

Carbide is better for CNC... cause of the rpm speeds... but can be used in any shop setting really. I have thought about going to pre-ground HSS.

[@Just1GuyMetalworks]

Agreed 😊. HSS is just a lot more affordable for the home gamer. Cheers! 😁

[@kentuckytrapper780]

Everybody's been wondering where you were, I told them you were in jail for stealing a lathe chuck! And I be damn you put it in your video. LoL Great job man, keep'um coming

Well, if I knew I would go to jail I would have nabbed a mill too 😁.

[@stewartfrye]

good job, Check your spindle bearings, adjust, maybe replace?

[@Just1GuyMetalworks]

They're babbit bearings however, I have reshimmed them since then and it's doing much better 😊.

[@davesalzer3220]

You’re exactly right on why that machine doesn’t like carbide. Try some positive geometry inserts. Tp worked good on my little lathe

[@Just1GuyMetalworks]

Thanks, Dave I will. Any recommendations? 🙂

[@danharold3087]

Good Video! Next time you have to deal with mill scale soak it in white vinegar for a day, Walmart has 5%. The mill scale is converted to something that you can more or less wash off. For flat surfaces I rinse then it give it a light pass with a palm sander. Looks like cold rolled. I suppose if your going to machine the surface there is no point in doing more then rinsing it. I have an atlas 10" with babbitt bearings. I bought a six jaw. It holds the works much better but the extra stick out from the front bearing reduces rigidity. Have you notice similar?

[@Just1GuyMetalworks]

Yeah that does work good. That ductile iron has some pretty thick scale, worth a try though 😊. Thanks, Dan! Cheers!

[@bhein67]

Well done! I applaud your problem solving, I would have said many bad words and started over.

[@Just1GuyMetalworks]

Lol, well it really wasn't out by much. Beats trying to cram a .001" shim in there lol. Thanks bhein67! Cheers! 😁

[@pgs8597]

G’day. It’s hard sometimes to get that perfect fit, good recovery though. Cheers Peter

[@Just1GuyMetalworks]

I'd like to blame it on bed wear, but giving my apparent inability to read a micrometer... 🤣 Really loving the new chuck. Thanks, Peter! Cheers! 😁

[@mr.picklesworth]

I'm looking to get a set of number and letter drills where didnyou get yours from and are you happy with them?

[@Just1GuyMetalworks]

I get all my cutting tools (endmills, drills, taps, blanks, etc) from KBC tools. I picked up the Cle-Line drills, reasonable price and decent quality 😊. #notsponsored

[@mr.picklesworth]

Did you get the chuck there also?

[@Just1GuyMetalworks]

@@mr.picklesworth Yup

[@paulerenberger1286]

Can you do a video of your lathe and what you have and what all you’ve done to it?

[@Just1GuyMetalworks]

I was actually planning on doing another repair video soon. I actually have a playlist with all of my mods and/or fixes so far, if you don't mind taking the long road 😊. Cheers!

[@noiwonttellyoumyname.4385]

I'm not sure you can run a babbitt head fast enough to really make use of carbide. They need a lot more surface speed than you expect, and a more aggressive cut. I have to run mine at absolute max speed to get good results, and with a cut aggressive enough to be right on the ragged edge of stalling at any time. Also- there really is a big difference between Chinesium carbide and American / European / Israeli stuff. If I just need a cut, I'll use a $6 Chinesium insert. If I need a *pretty* cut, I'll pull out a $65 Seco or ISCAR insert, and it looks like a damn mirror.

[@noiwonttellyoumyname.4385]

Also- is that your countershaft making the rattling noise?

[@Just1GuyMetalworks]

Well, the ol' girl was capable of doing 2200rpm in her prime lol. Watching the video myself made me wonder if increasing the feed rate might have helped. Gotta swap change gears every time so I just keep it at .0033" per rev. I don't really use inserts much but I'll have to set aside a day to do some experimentation 😊. Don't think I'll be dropping $65 on an insert any time soon though 😉.

[@Just1GuyMetalworks]

Most likely the back gears slapping around lol. Although that counter shaft is in the process of being replaced. Also gotta make up a spacer for the spindle assembly. So that sound could be the dogs on the small back gear and pulley. Either way, drives me nuts too, just trying to find the time to fix it 😏. Cheers!

[@noiwonttellyoumyname.4385]

@@Just1GuyMetalworks Y'oughta do an electric lead screw, then you can vary the feed rate however you want. On the fly, even. Re: countershaft- I gotta get around to replacing mine at some point, too. Just got too many projects going all at the same time right now. Been looking at just picking up 18" of precision-ground shaft and getting some needle-roller bearings, thrust washers, and a couple of shaft collars to stuff in some new housings. Seems like that should solve the problem for me well enough, and also keep from slinging oil all over my wall when I run the lathe. The back gear thing, though... that's another thing I gotta deal with. Mine doesn't like to stay engaged. Gotta figure out why, and tighten it up.
