We, my friends and I, tried splitting blanks from a block of clear wood with a froe. And making our own pegs from this stock with a shaving horse.
It was fun, but the block we chose didn't have the straightest grain wood in it and the pegs weren't the best.
We then took regular oak boards and cut them on a table saw into squares just a slight bit larger then the peg diameter and then shaved these into pegs.
We carefully inspected the peg stock for cross grain lines and usually the draw knife would catch on these lines and break the peg while we were trying to shape them.
We found this method to be fairly easy.
When we bought pegs we'd sometimes shape them on the shaving horse increasing or creating some taper for the draw boring of our frames.
