It was similar idea but incorporated into a 5 piece bamboo asiatic style bow. I’ll try a post a pic or two here if I can find it. Better yet here’s the link from my post on pa

Thats very interesting! Any reason you didn't choose to make it a BITH bow?

I was a little surprised that it worked out so well. I think this design would allow some pretty extreme stuff. I have a bow drawn out in the VirtualBow program that is an extreme r/d bend in the handle bow:
It has very low stress (90 MPa) at 40 lbs of draw weight and VirtualBow predicts a speed of ~200 fps with 10gpp. Friction will probably eat some of that, but still - there's probably room to stress it a little more.

That bow looks like a lots of fun Nic! And great execution! My hat's off (-S

I'm glad to see that you decided to post it here. I was the one that sent you the link. I have been doing this for quite a few years and really enjoy seeing 'different' ideas, like yours. You did a great job on it. :OK

Really cool. I love how narrow you were able to keep the limbs. The performance sounds pretty darn good! Do the limbs mostly contact near the tips of the smaller belly limbs?

Very interesting for sure. Looks like it worked out really well. Thanks for posting.
