I've been using repinique patterns on my tom. For sambas, I flip my tom over and use the thin reso head, then during the repinique section, I hust leave my left stick on the snare. I've been tossing around the idea of modding the rim to make it easier to use the hand. Then I realized my angle grinder that I use for granite came with a steel cutting wheel. The question I have, is how would I go about finishing or polishing the rim after it has been cut. Would I need to paint it to keep from oxidizing?
