GreyShadow I used a Delta 1x42 with 8" disc up until this year when a Dayton 2x48 went on sale for $228 shipping included! They have it back up to $358 now. It needs to be modified some, but nothing very hard and at 3/4 HP TEFC motor and over 4000 sfpm it hogs the metal off. Great buy on my part, it weighs 67 lbs so with the shipping included was a steal. Zoro company sells it. It is better in some ways than a 2x48 Kalamazoo. My last job had the 2x48 Kalamazoos and they are very good.
I use the ceramic belts for both grinders, Tru-Grit has an economy ceramic that hold up pretty well, but it isn't lubed like the better belts are so you need to lube them with a good belt lube. Belt lube I use is called Formax and it runs cooler and makes the belt cut extra long enough for the extra expense. Also do you have a belt cleaner? The rubberized stuff?
