Clean it up with emery cloth if you can without removing to much material.
Maybe even put it in a dril and pinch a Scotch Brite around it and spin it for about 10 seconds.
You won't see any difference going to CPI In Frames. In fact, maybe even less RPM. If you wanna try and get some more RPM, the shearers are the way to go. But they will not get a big fella like you moving out of the hole like the CPI's.
Nah, any one that has dealt with him said it'll take a bit, but it'll get here.
I was just curious about RRL's as I was looking at a used one a while back and was gonna swoop it up but was to slow.
