Someone was asking recently about how to polish hard-to-reach places;
well, I just saw this bench trick in JCK Magazine that looked useful
and thought I would pass it on. (I haven’t tried it yet.) The
technique was contributed by Jeffrey Mathews, CMBJ, of Jeffrey Mathews
Take an Adalox paper-backed aluminum oxide sanding disc. Put the
disc on its mandrel backwards. Then, while it’s spinning in your flex
shaft machine, rough up the paper backing by holding the disc against
the front side of a second, coarse-surfaced disc.
Apply polishing compound to the rough, paper backside of the first
sanding disc and use it in those hard-to-reach places. The roughed-up
paper surface should hold the charge of polishing compound easily.
Sounds like a great tip!
