Ok, so I've settled on crafting a sinew backed yew flatbow/paddlebow. The stave is 56 inches long, so 55 inches nock to nock. Really want to hit 27 inch draw.
I've kind of had to freestyle the dimensions here.
1 inch up, 2 1/2 down for the handle. 25mm across.
Fades last 1 inch and go from handle to 35mm width, and then taper down to around 20mm at the tips.
Add a few layers of sinew and eyeball the depth and alter during tiller.
How does this sound?
