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
