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:
