Cab machines are very nice but over rated.A poly arbor with a expando on one side and the other for switching out wheels worked for me for over 30 years of full time cutting. While flat laps are limited I love them for touching up problem spots and since I am careful while cutting I tend to use them dry or almost dry for that purpose.I use 80 hard then 220 hard then 220 soft nova. For hard stones I sometimes use a Eastwind 60 grit soft wheel after the 80 hard and then go straight nto220 nova. If I can walk ok on a given day that would be my choice for my pendants but the machine with the 60 grit soft is a hundred feet away and can't be moved closer and at times that is too far for me to walk.600 grit next then 1200, 3000, 8000,14,000 nova.I used to do all my coarse sanding on sic then follow with 100 grit nova then 220 nova but bad legs makes that difficult for me now due to the configuration of my shop.
