I'm pretty sure I have one of those around here somewhere. I never knew what it was, either!

Interesting: the valve lapping tools I've seen are designed for use back and forth - like a Boy/Girl/Cub Scout trying to start a fire with a dry stick.  I wonder if this was designed to use with a T-handle?

In one of my boxes, I've got a brace (tapered square shank) bit with a valve lapping end on it; but I don't have time to dig it out right now.  I don't have, and don't expect to have, any motors with valves with the little holes in the valve face required for that type of tool, so it's more a curiosity than a useful tool.

A tool like that is useful to old engine collectors like myself. I have 81 small engines at this moment with dates ranging from 1929 to about 1982. Most are old cast iron engines like Briggs & Stratton, Maytag, Clinton, Johnson Iron Horse, Reo, Continental, Fairbanks Morse and Tecumseh. I have been putting together a pretty good collection of tools for working on my old engines.

These sockets are made for braces.  In the 20's, many were welded/press-fit/notched on and couldn't be removed.  It was simply a valve lapper tool, not a brace.
