Went to a local flea market, A guy had a booth of scrap. Had a set of indicators which were a dollar per, decided to take a chance for a buck. Pretty sure the guy had no idea what they were, both work!! cleaned them up and am very pleased with my find. I would enjoy to hear what others have found at swap meets and such.
its for alot of things, it can be used as a travel indicator for moving in precise measurements if you machine does not have a DRO. it can be used to check flatness of a mill or lathe, another use is to mount it to a surface plate and measure the depth of holes. there are alot more uses but these are to name a few. Thanks for asking!
Ok so for 2 bucks that’s a steal ! :D
