Home Made angle plate for disk sander

[Tooler2]

You cannot appreciate a disc until you have worked with a big heavy machine, the disc alone is about 100 lbs each side. You can push much harder on a disk because a belt would stall due to the drive. Belts certainly have the advantage of changing grits in a few seconds, that is why I have multiple disc sanders. Most shops only change the bigger discs once or twice a year, they last many hours with skilled use.
