Cleaning And Polishing
 Up
Up
  This is my cleaning/polishing setup. I clean off light rust and
  grime using a 8 inch wire wheel, mounted on a 1 HP, 3450 RPM motor.
  The speed helps prolong the life of the brush, as the wire in the
  brush does not bend as much at high speed. The horsepower allows me
  to push into the brush and clean quickly.
  
  I polish stuff on a 3/4 HP Baldor grinder, where I have a 8 inch
  Norton Bear-Tex
  fine polishing wheel mounted. With a little experience, I can do a simple cleaning
  and polishing job in one minute.
