Brown and Sharpe Micrometer Information

Post by croach1776 » Mon Jan 13, 2020 1:50 pm

I have recently purchased a few B&S 0 = 1" micrometers and have done some preliminary research on use and care and repair. So any information would be helpful. I think that the type I have dont have the hole for the spanner on the sleeve and that the only way I have found to adjust them is to
remove the thimble enough to expose the collet collar or adjusting nut threaded onto the barrel. So my question is; Are there micrometers that use this method of adjustment as the only way to achieve zero. Thanks

Or this, if it's being difficult:

What models of B & S micrometers do you have? Many times, adjustment instructions can be found in the older catalogs. Pictures of what you have would be helpful, too.

The "adjusting nut threaded onto the barrel" you refer to is the nut used to adjust the threads to take out the play in them. It doesn't affect the calibration of the micrometer.
