Disc sander

Some have asked what disc sander I use. It is a big 50cm (20") disc mounted on my lathe. It's easy to mount and also easy to disasemble with two bolts. The speed regulation is done by a inverter. This inverter is 230V. The input is single phase but the output is 3 phase. The motor on the lathe is a 1.5 KW , 750 Upm. There is also a triple V belt transmission. The sanding disc can only be mounted when transmission is at it lowest. This means that the revolution of the disc is half the motor revolution.

When I have to sand very small pieces the speed is set to very low (1 revolution per second) to prevent injuries. There is also the benefit ot the speed different between the inner and the outer side of the big disc.

Below some pictures:

That is really neat. Like your large disc, must start looking for one as it would be better than one made out of wood. Funny how I made a disc sanding attachment for my lathe with a two way vise for micro adjustment, but only used it for wheels… never considered this type of sanding as my dedicated disc sander was already set up for instant use. Will need to re-think my methodology.

Thanks for sharing.

PS.
... (1 revolution per second) to prevent injuries.

Wouldn't 60 RPM be safer??? But then on hindsight, 1 is (s)lower than 60…

Man those slow speeds sound really great, just right for the small stuff.
