I was looking into getting a horizontal disk grinder but since I wouldn't use it that much I didn't want to buy a complete outfit. Then I was thinking whether I could attach a 9" disk to the end of a buffer arm. I have a 3/4 hp (1800 rpm) baldor. I would need some kind of adapter to convert the threaded end of the buffer arm to a standard driveshaft in order to attach the disk. Is this possible? or would it not run true? or is this just an absurd idea altogether.
