Noobie With A Very Old Sb Lathe

[RobertHaas]

I have to study so that I can rise up to the level of knowing nothing at all. Truly out of my element here but I am an old man with a bunch of tools so I sure hope I can figure this thing out.

This is a very old unit with a 6' bed. the serial number is 8342

The head stock and tail stock are solid, however the cross slide has quite a bit of play in the threads.

I tore it down and cleaned it up, the Gibs adjusted well and maintain a nice smooth run full throw.

Not sure how to get the play out of it. over a hundred thou.

I honestly will try to learn by searching and not just show up and start asking dumb questions. (actually most of my questions are pretty dumb)

I had similar problems with my Logan. I was able to get a replacement cross slide nut from a guy on ebay -- derewa2. It reduced the slop from about 120 thou to 20 thou.

regards,
Leon

Sometimes the lead screw nut is loose where it attaches to the cross slide. Also, sometimes the feed knob arrangement is put together wrong or is missing a thrust washer, spacer or something similar. .100" backlash does not likely come from a worn lead screw...

Dose it have a taper attachement ? , what SB is it ?. You can probably get new repop nuts and screws for X slide /compound.

No dumb questions. Your will get a lot of good advice here, and once you get into it the issue will make itself known. Sounds like you have some skills and it will probably be a fairly simple fix. Welcome to the forum. Mike

Robert, You are doing great. Just jump right in here. As already said above you need to look at the lead-screw and nut. Welcome to the site!

I ordered the nut last night, Thanks for the link.

The screw will probably be a more difficult part to replace, it has an integrated gear on it.

Anyway to identify what lathe this is?

I will post up a couple pictures today and see if I should continue down this path of restoration.

I had an old oil can that has been in my shop for thirty years or so, I cleaned it up and will keep it near the lathe to keep the ol girl slippery. 30 weight OK to use?
