Yeah, I know you wanted to carve them yourself, but... I've been both directions down that road.
Bought a Virginia Dragoon 44 mag back in 1980, before the internet and being able to find anything and everything you could possibly imagine. Gun was notorious for rolling up in my hand when shot; carved a set of grips for it out of a piece Red Oak firewood. Was a terrific improvement.
Opposite respect, put a set of Pachmayr half rubber grips on my 1911; I can't imagine a more perfect grip on that one fit, finish, and function on those are simply too sweet.
