I have rediscovered in a box what I assume was a car boot purchase some years back. I've found one image online of the same – a grinding and polishing head by J. F. Turner. Spindle is 1/2", 6" from base.

I've given it an initial clean up, removed rust from the pigtail and filed its threads smooth again.
I have a few old single phase motors available – a 1/2 and a couple at 3/4 HP, though yet to find any of the pulley wheels that came off them. I'm considering 6" or 4.5" wheels.
I wonder if anyone reading this has mounted similar or knows where I might find any examples or plans. Appreciate a simple motor mount is not particularly difficult to construct, but nice to see others. Any suggestions re: motor, wheel diameter and spindle speed would also be appreciated.
Edit: rather than necessarily being bench-mounted, I'm also considering a wall-mounted unit to keep the floor clear.
