Nice idea on the concave.
I also never thought about using heat
I still havent tried doing rails yet, but I think that one is next
the real problem is you lose so much integrity
especially with molded boards on the skin
and glass boards with the wrap
Tips are simple and very effective
I have been called Dr. Frankenboard by my bros
for chopping old boards down
to remove rocker mostly, and shorten them up
Nothing like taking a jigsaw to your board is there?!
I agonized over the first one
what if !!????
Once you get past the idea of it
you realize its really no big deal
it wasnt what you wanted anymore, and
its more fun to experiment than let it gather dust anyway
