That's a sweet lil' bow! I'm not really into short bows myself, but this one is well executed. How long is it?
It appears to be all heartwood, right? Is that for a particular reason? I'm wondering how sapwood would perform under sinew. I can imagine the heartwood is better in compression, but then again, the sapwood might be a good core wood choice as 'lamination'. Did you flip the tips with dry heat or steam?
That's a great bow you got there. Sweet tiller.
