I've got a B-rated set of gage blocks I bought from Shars a while back. Not great, but good enough for most of what I need them for. Sadlysomewhere along the way my .050 went missing. Its kind of important for a whole range of measurements, but its gone. I'm sure its in my shop somewhere... unless it got swept up and thrown away ... I don't want to have to buy a-whole-nuther set for one lousy gage block. Does anybody sell one off pick and choose fill in parts?
