For Lynn Hanover,
In a recent post your suggested method for freshening the side housing finish
was to use an orbital sander with 400 grit carbide on a "DA" pad keeping the iron
wet with kerosene or diesel fuel........Pardon my ignorance but just exactly what is
a "DA" pad.........Thanks

Any brand of air powered random orbital sander using a number of round disc diameters. The standard equipment in any body shop. The DA on every box they come in is for "Dual Action"
so, like every tissue being called a Kleenex, every round pad orbital is a DA.
The dual action is a lock on the little counterweight that if unused gives you orbital action and if locked gives you a straight grinder.
The replacement pads have a short 1/4 X 28 thread for mounting. The pad faces are slick for self stick paper or textured for glue on paper or have the hook half of the hook and loop (Velcro) system. Keep one pad just for wet work, and never get it near a car finish.
Air powered is a bit safer when working in the cleaning tank with a stream of kerosene running onto the work. But you could use an electric outside if required.
Use the glue on pad. Foam backing with a smooth cloth surface.
Don't forget the pad glue. Use it like contact cement. To change pads, heat the paper face with a torch just for a second. Peel off the old paper and stick on the new paper before the pad cools. You can go through several paper discs before you need more glue.
Yes, I did work in a body shop.
