On day two of owning my Cab King, I picked this up to work on. Don't ask me why I always challenge myself to tough jobs.
Anyway, the rock is getting shiny and feels totally smooth, yet I have these tiny scratches in the clear part of the rock. Should I stay on the right side of the Cab King? What is the lowest wheel I should drop down to at this point?
The only real scratches I see are from the 80 grit, so go to the next wheel otherwise you are wasting your time.
You are GREATLY appreciated. Thank you for your time and effort.
A lesson most of us learn the hard way. The toughest thing for me is seeing the scratches. Drying and inspecting, rubbing a pencil. Sometimes I need to get to the polish to see them. It is frustrating. When working with softer jaspers they are more forgiving. 80 grit scratches unless really deep can be fixed with the 280 or 600 soft. Porcelain jaspers and agates can't.
You might get yourself a lighted magnifier to keep next to your cab unit. It helps, that after you dry off the rock, look at it under magnification, you'll be surprised how many scratches there are.

You're getting a lot of great tips. That is a tough little piece to work with. It has the softer dark sections that undercut, meaning it will grind easier than the agate and wear away faster and the small particles of that matrix, the soft darker host rock, can contaminate the agate causing scratches. You could try grinding on the 220 wheel but stay in one direction on the stone either lengthwise or widthwise, and then move to the next wheel, 280 and grind in the opposite direction. That way you will see which scratches get removed. I hope that makes sense.
