You only hit them once! Trust me, the learning curve is a quick one. I
usually sand these with the lathe off.

Barry, as Darrell said you only do it once and then learn to keep your
hands well clear of the edges. Darrell, I use a power sander to sand
the bowls but do it very carefully. After a couple of bowls one learns
to hold the sander very lightly against the bowl. I only lost a couple
corners of a couple bowls but I sure developed good reflexes.
