I bought a lathe, the first I will have run since college, that needs some TLC before it's usable. I'm in the process of refurbishing it, but while parts soaking in the stripping tank or paint is drying, I've turned my attention to the pile of instruments I got as well. I'm much more comfortable taking apart the lathe than I am these instruments, so I'm hoping you guys can point me in the right direction. I think there are some really good pieces here, if I could get them in tip-top shape again, is possible.
Forgive me if some of these questions seem stupid, but I just really don't want to accidentally break any of these sensitive little guys. Bear with me!
I suppose I'll go through the known problems first. I think you can click on the images for larger versions.
First off, this smaller mitituyo caliper:
It feels a little crunchy, but more importantly, the face of the dial doesn't move with the knurled ring around the dial. Are fake mitituyos a thing? The dial face locking screw barely holds the face, and the slide locking screw is very tight. Otherwise, the thing looks great. What's the best way to approach disassmebling the dial?
Next is this depth mic:
This needs some cleanup as well, but what I'm really worried about is a small amount of axial play. Are these things adjustable for backlash?
Here is a Blake co-ax indicator:
Seems like a neat little tool, but it's frozen solid. is there oil or solvent I could soak these in to free them up and clean them without harming the internals? After doing a bit of research, I'm worried the brass bushings may need some honing.
And I think I reached the attachment limit. Stay tuned for part 2...
