since I got the minilathe I have always wished for a bigger and especially more rigid lathe. That I found a couple months ago, and I bought a very old lathe for near nothing.
I have it now torn down, painted and am about to build it back together.
However I have a small problem with the spindle assembly: it was turning smootly before teardown but now I just put everything in place it's binding when I screw everything together.
It is an old type assembly: bronze bearings, just one thrust ball bearing in the back.
Is there a special procedure and things I have to check out to get such old bronze bearings back adjusted finely?
What are the locking rings for, they seem to have no effect. Any help will be greatly appreciated.
Plan is to try to retrofit it to CNC later on, but I would really like to have it running as is first
Here are some pictures of the work in progress.
