Question

what is applied to protect tha slip gauge from rust?

Answer 1

Answer:

Keep steel blocks coated with a rust preventative oil such as Starrett M-1 when not in use. It is recommended that if the gages are going to be stored overnight or be taken out of use, that they be wiped all over with a chamois dampened with a rust preventative oil such as Starrett M-1. Use the handling procedure as above, and do not touch the blocks during handling or placing them in their case.
