Hello all,
I need to remove the thimble off a high precision Mitutoyo micrometer head. Its part of the stage controls of a Scanning Electron Microscope, and we need to replace vacuum seals for it.
However, since we managed to lose the manual on how to dissemble the micrometer, i thought id give this forum a try and see if anyone knows how to safely remove the thimble from the head.
Unlike a normal measurement micrometer there is no ratchet on the end of the thimble, instead its just a thumbscrew.
The reason im looking into the removal of the thimble is due to the micrometer head blocking access to the fasteners holding the o-ring against the shaft of the micrometer head.
Here are pictures of the micrometer heads in question:
don't be fooled by the reflection from the door of the microscope.
edit: i should probably add that i had removed one of the thumbscrews before i took the pictures, i do infarct have it.
