When you need to sand those small parts or the flat ones that are
really tough to hang on to, or they get too hot to hold while you are
sanding them. Take a regular gum rubber eraser. Place the eraser on
top of the piece to be sanded and the sand paper beneath it and hold
on to the eraser. The piece will embed into the erase just enough to
be able to move it back and forth on the sandpaper. No heat and you
don’t sand your fingers or finger nails away. Frank Goss
