Randman, Not sure about the wood. I am very bad at discerning species based on appearance of wood. However, it does have more of a pinkish tint than even some of my other red oak boards. I intend to ad some more bells and whistles to the tillering stick once I get a bow or two under my belt. My thought process was that I didn't want to spend a ton of time making an overly elaborate tree only to find out that I didn't like bow making.
That said, I don't think I've enjoyed working on a project this much in quite a while. If making a bow is this satisfying, how much more so will it be to hold the finished project in my hand and shoot it. I think when I head to my parents house this weekend I'm going to check out their home improvement stores and see if I can find some things to improve my tillering tree and perhaps if they have any good boards.
Back to the project: I've finished roughing the sides of the limbs. Next I'm going to go knock out the handle area. In preparation for removing wood from the belly to get the bow to thickness I wanted to ask a question. From what I've read a pyramid bow has a fairly uniform thickness down the limbs. For a 70" ntn bow (2" wide at the fades to 1/2" at the tips, with 9" rigid handle) how thick should I be shooting for? I'm trying for about 45# at 28".
