I have a sanding job that requires sanding inside many small pockets - a few thousand. I tested the speed I could get doing it by hand, and it might be as much of a week of non-stop work. It's time for power tools.
What tools are there for sanding inside small pockets, quickly? The pockets are slightly larger than 1" x 1", and 1" deep, plus a 45º slope extending out one side, for the smallest pockets. There are larger pockets in the job, also. Heck, what tools are there overall, for sanding inside pockets?
I know some people use emery boards, others use sanding sticks, some use abrasive nylon rotary tool wheels. What all options are out there?
