Hmmm---I'd be very interested in this! For one thing, I quite enjoy making things. Heck, I even made a DIY 'jawjacker' that I can't be bothered using! Second--I was searching on the net and it seems most everybody is sold out of Clam plates.
I did drill a couple of holes about years ago but the potential for a serious wrist injury scared me off. I just had the little adapter from CTC.
