Well, after finding out that sanding with diamond is pretty easy and cost effective, I'm willing to look at additional sanding steps.
The reason this is coming to mind again is because of all the ridges in my last batch of stones. Yes, if I had worked smaller batches I'd have been able to get rid of the worst of the ridges, but not all.
Looking though Riggle's diamond abrasives book again I noticed that he suggests sanding with near the same grit size as the fine grind (280). He states "The cutting action, however, is not the same because the smoothing wheel or disk has the cushioned surface, which has a gentler effect. With this grit, the scratches, plus any bumps or tiny flat spots that may have been left by the grinding wheel are smoothed away". That right there describes my complaint.
So not only have I ordered 220 grit diamond paste (closest to 280) but I'm going to try out a dura-tex pad. I can't tell from the descriptions if it is more laplike (stiff and flat) or more like a pad. However, it appears to hold the diamond grit better which might translate to more aggressive sanding.
If that works out, I'll replace the other sanding disks with dura-tex pads as they wear out.
I'm curious about polishing with diamond, but I don't see the point in the additional cost before I'm able to sell my end product.
