Engine turning brushes from Brownells and fine valve grinding paste used, = about $20.
Instructions I found said to bring brush down for 15sec in each place, and maybe I was applying too much pressure with the drill press but I found it was WAY too much at 15sec - shallow divots and minor burn marks (purpling). So I only did about 7-8sec at the end, (as a result the best jewelling is on the underside where it will never be seen hahaha)
But on the whole, happy
