Chainsaw is used to cut the end of the tenon only, for the most part, no score line just pencil and half the line. I score the diagonal seat cut on large rafters and cut with a chainsaw sometimes, than pare to the line, spruce is the worst. I am working toward a skillsaw for those cuts. Most of my cuts are made via Docking Saw and taking half the line, no score. The axe goes to the line and rarely beyond, than finished with the slick, half the line. Tim
