What are the opinions of using a Foley Belsaw model 1055 as a light to mid-duty grinder? I believe it has a 4" wheel and a larger 8" wheel coupled to a 1/2 hp 6.2 amp motor? I don't know the arbor size, or if I can mount wheels of other sizes. There seems to be one available for $100. Or should I hold out for a real grinder? Thanks
