Thanks for the help from all of you.

I have stair gauges, and I can do the layout (I think). I'm a Licensed General Building Contractor, so rafter layout is familiar to me. I assume I would use basically standard layout techniques.

I'm intending to move into more traditional building styles, and am planning on starting maybe with a Jack Sobon style shed. I'm not a master with a chisel, however.

What I'm a little unsure about is how to cut the inside "notch" portion, and maintain the proper angle. I practiced on a scrap piece of timber I had, and my angle was a bit....uh....off.
