Recently disassembled, cleaned the movement in the ultrasonic bath, oiled and reassembled a 1/10ths indicator. Rather like doing brain surgery on a cat. The scary part was it worked when I was done.
Was dialling in a 1 inch hardened and ground shaft to make a test rod for the lathe. Used the 1/2 thou test indicator, then thought I'd dig out the never used 1/10ths one I had. Got no movement when I rotated the shaft, hum, the indicator seamed sluggish so I thought it needed cleaning. Hence the maintenance, after cleaning it was more responsive. Put it on the shaft, still not a wiggle. Guess the ground shaft was truly round and smooth and I hit it dead on with the 1/2 thou one.
Even a blind squirrel gets an acorn once in a while.

Free advice is worth exactly what you payed for it.
