escapee - I started grinning again when I went to the pump.

Polishing stainless - I knocked all the high spots off with a file. Then I started with emry cloth - 240, then went to silicone carbide wet/dry 320, 400, 600, 1500(not necessary). I used lots of WD-40 - keeps the paper sharp longer. Every time I changed grit I cleaned the impeller with simple green and hot water. For the real pitted area I used a dremel with some rubber abrassive wheels. They are actually called MX wheels and I order them from a company out of California called Artco.

Did your buddy machine the leading edge?
