I don’t own any micrometers... until now

A chap locally was clearing his old measuring equipment and they caught my eye. Managed to snag a 1” and 2” and now I’m doing what I always do... pulling them totally apart.



The 1” has an analogue digital readout (metric) and imperial shaft. I have it completely apart and have a few questions.

1. What’s a good oil to use now I’m putting it back together again? 3-1?
2. My 2” has a really nice ratchet feature and I can’t work out if the 1” is supposed to have something similar. The end barrel has a locking mechanism for 1 way but spins freely the other way. Is that how it’s supposed to work?
