I am not sure if this unit needs or is meant to have an arbor shaft or not. I have not dealt with enough slant laps to make that determination. It is one of those older models made out steel and built like a 55 Chevy, with a good motor with excellent bearings as far as I can tell. It has its own water supply that looks almost like a lawn mower gas tank in miniature. I believe it is an old Lortone or Highland Park. No label on it. Blue powder painted.
Excuse my naivety, but the unit never appeared to have an arbor, although there is a 5/8" hole in the center that appears to be how the lap is attached to the unit. Do you use a glued discs, something magnetic, or make an arbor? The outer( rubber?) ring seems to be something used to retain a grinding disc on the lap plate? Not sure as it does not exactly fit the lap plate.
I bought it as a challenge, as it was not expensive relative to new ones, and if I can get it running, I could do some things I have not done before. Another reason my dad did lapidary on a horizontal flat lap back in the early seventies. Got me started in this, of and on over the years, especially the last seven years. Any help would be gratefully appreciated.

A picture would be helpful.
