You could wrap it in aluminum foil and heat it in the oven.
What was the cost?I had the same problem with mine. I sent it to Precision Instrument Correction.

They fixed it and calibrated it.
IIRC, it was about $95What was the cost?
have a 224 n which does not ratchet, rendering it useless, spindle is free, any ideas pleaseI 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!

https://www.starrett.com/spare-part...=list-condensed&itemsPerPage=24&sortBy=wp/asc for Starrett USA for parts or Amazon.com Starrett can get the part number for your micrometer 242. phone (978) 249-3551 https://www.starrett.com/about/contact-us
Go on a free site or ebay to get part number of the ratchet and then look for other micrometer models that uses the same ratchet. I suspect that Starrett uses are only a few different ratchets (most use the same one $12).
Find a bent caliper from a garage sale for near free to ebay for a few dollars. My free micrometer was perfect except the spindle didn't rotate at all. I cut out a spring from a broken self grounding electrical outlet, then bent it to fit. You might get the spring and ratchet for near free.
