SU float bowl Polished

Those look amazing. How do I do that myself?

Use a sanding disc to remove the casting lines that run vertical on the bowl. Then wet-sand everything with 400 then 600 grit sandpaper. Then I used black rouge? compound on a 4" buffing wheel (spiral sewn for strength) The smaller the wheel, the easier to get into the small areas. It takes a while but well worth it, as you can see. Use a soft cotton cloth to polish off the dust and residue. This was all done on a 1/2hp bench grinder
