After the turning the Purpleheart was dead brown, placed it in the sun for appox 4 hours and it turned the color you see. As for the finish, I'm still playing around but so far I sand thru 1200 grit, put on a coat of shellac to fill the pores and then use Shelawax and then last a coat of Carbunba Wax,all applyed while still on lathe.
