Thanks for posting detailed pictures of that ratchet.  I really like it.  I must wonder what the story is with having a detachable handle.  Compact storage?  Interchangeable tooling?

Handles bend when a piece of "pipe" is slid onto it for more torque.
I'm too old now to even think of breaking loose headbolts requiring that much effort.
Instead, I could fire up the compressor, set to a high air flow, and then use my USA made 3/4" drive air ratchet!

A few other things from the garage

That is a key cutter grinder!   Kind of a big layout, usually the motor unit is rather compact.  Like the idea of a shield over the wire brush.   Looks like a brand new oiler or water separator, for inline air too.   Have you hit bottom yet?  Was there more than just the buckets?

No, I haven't hit bottom yet, just barely scratching the surface.

Cool findings so far

Keep us posted please
