and the hand-grip
profiles using the
two patterns provided
in the kit. cut the
profile for the top
first as shown and
then lay the bow on
its side to further cut
the hand-grip
area.
I fiuse a combi-
I \-fnation of
rasps and small
drum sanders to
custom-fit the bow
to your hand. Once
you get it right, start
sanding the wood
areas with 80-grit
sandpaper. Don't
sand the fiberglass
surfaces with anything
less than 120grit
sandpaper or
you'll leave deep
scratches that are
hard to remove.
