Thanks guys for your input!
Sorry, I meant the knot is on the belly not the back. I was getting impatient waiting for a good piece and had to cut the board a little short because of a big knot. I went for the Flat bow design at Archery library, which lay it out narrower then I have but it says nothing about draw weight and figured the first one is a learning experiment. My draw length is 27.5 and might never get there with this one but that is fine, I can give it away.
So if I have it bend through the handle could I get to maybe 27? I'd be fine with that. And if the knots are on the belly and left side with some linen backing this could maybe make a bow?
