If you're using pegs to save weight...why run them? Those would snap and wear away so flipping quick. Why not try what a few have tried before? Find a way to make a peg that rolls. Just make it a sleeve that goes over a peg and rolls.
because that is the most retarded idea since your conception.
I know they would suck, but if he's going to waste his effort, he might as well try and make something people haven't made millions of times but with a slightly different thickness. And my conception wasn't planned, I was an accident; as I'm guessing you were.
