I bought a populated machinist's rollaway once. It has one drawer in which
live a set of round "space blocks" which can be called gage blocks too. These
are all the same diameter and have a central threaded hole. In that same
drawer are two identical tools. These were commercially made and they were
die-cast from pot metal and not finish machined at all. They are labeled'
"Tommy Gage" and at one end they say "GO" and at the other they say "NO GO".
I'm a reasonably savvy guy but in the 5 or so years I've owned these I still
haven't figured out how to use these. They are formed in 2 halves which are
threaded together with a knurled finger bolt. It seems you could somehow
clamp them together with a space block to get a go/no go gage, but I can't
figure out how.
Anyone know about these? I can post a picture if needed.
And yes, I've googled.
