Nice work. I'm considering the same thing for (all) my Atlas equipment. They are really starting to show it's age and it's time to get it done. Thanks for sharing.
It was a pretty good project, and not to hard for even my beginner skills. Best wishes!
I will never understand how you just seem to know how to restore this machine and its parts! Impressive. I liked your cool effect at the 1:30 mark to explain some previous work. I got tricked at one point because there was a lot of machine noise in the background at the maker space and I thought something in my house was buzzing- kept pausing to check! 😝 I hope you’re enjoying seeing your restoration through. =)
Thanks! I do a lot of research and watching other's videos. That's how I figure this stuff out. Thanks for watching. :-)
Cartoon Kevin was my fave part. Thanks for skipping through the "boring maths" lol
There is a youtube video that I downloaded that has about 30 of those SpongeBob segments. I just scroll through to find what I need. No one ever misses that boring old math! Thanks for the comment! P.S. I just went back and looked at the video. That tiedye shirt is loud!
I have never worked on a lathe that didn't have some backlash. Keep up the good work. I'm enjoying your progress and I don't have to get grease on my hands. lol
But, but, but ... I want it to be perfect! LOL! Thanks for the encouragement.
Hello great video ,I had the same problem on my southbend 13 lathe with the slop (backlash) on my lead screw . I could either make a thicker brass washer that goes in-between the two metal washer and take up the slop there,but instead i redrilled another hole on a different spot on the coller that had slot machined into it if that makes sense.
It's been a bit since I dealt with all that. It seems that I ended up taking out backlash with the nut on the handle?? But your solution sounds good too. Thanks for watching!
I am going to do the same thing on my 9" model A, looking forward to your nut video. Thanks!
I have the footage, I just need to get it all organized. Hopefully it will be out in the next week or so!
I always find it easier to drill, bore or ream a hole first and then fit the shaft to the hole. It's easier to file or grind an OD. As an FYI. I have a 1939 SB 13" x 60" that I've had since the mid 1970's.
Wow! That's awesome about your lathe. Any suggestions about fixing that slop coming from the handle end of the screw? And that is a good pointer about starting with the hole, and then matching OD. I'll do that next time.
I wanted to do this to mine, but at the time, didn't have the guts to do it, or a second lathe. Now that the maker space is back open, this might be something I will want to tackle again in the future.
It ended up being a bit easier than I had anticipated. But still there was lots of opportunity for disaster! FYI, I bought my replacement screws at www.roton.com (no affiliation). Their prices were good and prompt shipping.
Usually the graduated sleeve would be on in front of the handwheel and meant take up that slop. I noticed there wasnt one in between when you were testing. ??
I don't know. I think I put it back together the way I got it. I'll have to look at that next time I am in the shop. Thanks!
OMG your crushing the thrust bearing. how can you do so much metal work. and not know what a thrust bearing is?
Well dang it, I hadn't considered that. This is a hobby, and I am learning as I go. I have tried to find drawings of this part, esp with any clues of how to take it apart. I haven't been able to find any, but if I had they might have shown me the internals. It does seem to still turn OK, so perhaps I didn't really cause permanent damage. Thanks for the pointer!
@@KevinToppenberg I have a Southbend 9 model b which I'm not using. so after watching your video, I grabbed the compound slide from that machine; and it's nothing at all like the one you have. Although it was even harder to take apart. I gave up, so not to damage it. Good luck with your restoration. I will be following it with interest.
