Hey James and Cyndi,
Very nice machine!
The one I have is a covington 6inch combo unit. The grit sizes I went with was 80g diamond wheel, 220g diamond wheel, 400g expandable drum, & felt pads on the end that I switch out using diamond pastes of 14,000g, 50,000g, & 100,000g.

for face polishing large agates we use a 10" covington vibrolap.
