1x30 2 wheel grinders?
I found myself in an in between place for polishing up stone. I have diamond wheels but not in the higher grades and the SC belts I use go up to 600 grit. Talking with some stone hounds the 9 micron diamond belts would work quite well. (Would also like 25 and 15 micron sizxes.) So I hit up Tru Grit and found out that a 2x72" is in the $100 range and I have a minimum order of 2. Scott suggested a 1x30" belt.
Looking at 1x30" sanders they tend to be 3 wheel types. I would like to be able to grind on a contact wheel. The other issue is that they run at high SFPM rates so grinding stone wet needs to be done at low speeds.
To build up a variable 1x30 rig I may as well just pop for the 2x72" to use on the big Burr King.
Thoughts? Sources for 2x72" diamond belts?
