My 32 year old Starrett edge finder has always worked perfect but to day it is giving me all kinds of goofy readings. I cranked the mill table over to find zero then set the dial setting to zero, the table locks are snug. Then I cranked back then forward to check zero again and the edge finder gives me a reading of minus +.003" on the dial. I reset the dial tried again this time I get a reading of +.005". Whats up with this? Try again I get -.002". Try again I get -.005". Try again I get +.001". Try again I get -.002".
Removed the edge finder from the mill and inspected it. It looks fine but trying to slide the tip with my finger it does not slide easy.
I put oil in it that did not work. I tried different types of lube none of them keep it from sticking. I tested it in the mill and I still get all sorts of goofy reading from +.003" to -.005" either side of zero.
I never had this problem before whats up with this???
