I found what I thought was a great deal on a little used Starrett T230RL 1" micrometer. It had some old gunk on it, so I thought that was why the spindle was sticky when turned. I took the spindle out, cleaned and degreased everything, and it is still so tight I can't use the ratchet.
Upon looking at it, it appears the spindle lock mechanism isn't retracting enough and is dragging on the spindle. It will turn to a stop and lock the spindle, but it will spin all the way around the other way and release a bit, but not enough for the mic to spin freely. I found a bit of info on line, and several mentioned that, when the thing is apart, DON'T turn the spindle lock. I'm sure I did when cleaning it. Nothing I can find mentioned how to fix this issue.
It may be related, but it's off zero by about .0005, and I tried to rotate the barrel with the spanner, and it won't budge. Thanks for any advice!
