It is a cheapy Chinese mini DP, $40 at the Homier traveling tool show. Something like
4 1/2" center-to-column and with a 4 speed set of pulleys on top. Very standard and low- end, can't lock the quill in place. The motor is 1700 rpm (not 1725). Works well but the lowest speed has this tacky chafing sound first time I ran it, so, must be some runout.
I imagine one could place a larger single gulley wheel on the front spindle, or something like that...? I know a variable speed DC motor and control board would be really expensive, after all the searching I've done. Doing a jack shaft is too much for me.
Slow for a spinning wheel strop with leather on top of the disc. Used for honing wood- working chisels and handplane blades. Don't want the steel to turn blue because it's too fast.
I have had the arbor made with threading, and the wooden discs are glued up but it's not finished quite yet. All that should make more sense.
