What do you call this 'whattayacallit'?

Am I going senile or have I overdosed on Metamucil? I could have sworn that, years ago at least, one could buy little steel tubes with a specific OD and an ID to accept popular size drills.

Crowned pulleys

I've read the postings here about crowned, flat-belt pulleys, and get the impression that, while not rocket science, crowning with a fixed radius is not the easiest thing for a home machinist to do. Well, I am not even a home machinist, but have a need to get an existing pulley crowned. The guy who ...
