As others mentioned you need to start with a block and paper. Use some dowels and other shaped wood to get into radiuses. I would start with 600 and work your way to crocus cloth or 1200 before you start with a polishing wheel. Then work your way through the 3 rouges. Final polish with a cheese cloth and something like simichrome or flitz. You will need to disassemble everything and make sure all the excess rouge is removed with something like mineral spirits. Personally I wouldnt do it.
