fine grit hammer filing; Dremel tool

[Joe And Penny Goss]

Hi David,
That is exactly the same experience that I had. Tried all of the motorized
ways after first finding that the paddle made my elbows flare up. My system
is really just a non-motorized version of Carl Meyer's electric knife.
Becuase I can control the speed of the removal of felt I remain in control
of the results. Not so withthe Dremel, McCall, and meyer system. That is not
to say that there are not those who are quite skillful with those methods,
but I am diffinately not <G>
