We've got a killer good swap meet here.

If you don't find one, let me know.

I've been putting together a junkyard tool box.
Tools are a touch mismatched, but all American made.
Some found at garage sales, but most from the swap meet.

Along those same lines, what do you think about doing a European style speed wrench?

A "T" wrench that's nothing more than the slider bar and a 10" extension.
Craftsman based and the slider was brazed on center many years ago.
Better imo because it's not dedicated to a particular socket size.

Mine is 3/8" and I use it probably more than I do the speed handle.

Got the idea from the opening scenes of Cinerama's Grand Prix starring James Garner.

Far as I know gennie European speed wrenches or whatever they call them are a dedicated size.

If I were to make another one I'd use JB Weld to hold the slider on center.
