I picked up a 1060's Craftsman 12" lathe at a garage sale, 54" wide, a set of little used gouges (?), a 1725 RPM 1/2 HP motor, a wide tool rest, and some miscellany. In that last category are two drive centers (one a spike, one a cup), two different sized mounting plates (?), one new buffing pad, a plate for sanding, and a package of sandpaper for it. The lathe is not mounted on a board. The motor is not mounted and makes some minor noise after 60 seconds - possibly I need to heed the plaque that says "Oil Every 10 Years." Or it needs brushes, or it's bad, or whatever. Everything, with the possible exception of the motor, seems to be unused or in good condition. Plus the manual, printed in 1964. $40. Looks like:
288355
So I figured out what pulley grooves (4 on both the motor and the lathe) will produce what speed - 825 - 4100 RPM using a 1725 RPM motor. I worked out a design that will allow me to adjust belt tension by adjusting the motor mount (pivot or sliding, yet to be determined), which I plan to do below the lathe pulleys. Workshop space is limited and this seems like it will take less space. I doubt I will use it much, so I imagine 1/2 HP is adequate.
I think I grasp tapping out the drive centers through the access hole in the housing (I haven't done it yet). But I don't understand how the mounting plates (is that the correct term?) attach on the headstock spindle (is that the correct term?)? They look like:
288356
The inside of the boss is smooth, although I think I remember a set screw.
Are there any exceptionally useful links?
How do the mounting plates mount on the headstock spindle?
Is it practical to use for buffing? And if so, what about mounting a shaft to the tailstock and have several buffing wheels mounted?
The more I learn, the less I know.
