That is the exact same way I attach crotches when hand splitting. A SS works just the same as hand splitting, it is just that the operator does not get tired as quickly, and the wood piles up faster.Try this on a crotch piece. When you have a Y split the lead on each side in half(the edges of the Y). The turn the piece you have left around. Set the piece on it's side.(split side on the beam) and split it. After it is split you know have 2 y's. Split both y's right in the middle of the crotch. It works like a charm.
