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.

I like the stress curve and am watching with interest to see how you work out the design with the leafspring idea.

I'll be sure to post it here if I get to make it. But I probably have to wait for a piece of wood that is clean and straight enough - otherwise it will be a nightmare to balance and align, I think.

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?

I think that is one of the main benefits of this design: It is wide and narrow at the same time!

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

Thank you for the kind words simk!

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.   

Thank you bob, I really like r/Bowyer for the great community, but there's just an amount of cumulative experience here that is unmatched anywhere else.

Congratulations Arvin. Hopefully we’ll get to see that full draw picture when you take it to the flight shoot.

This has gdda be the first time in history a bow won without a full draw picture.

Congratulations Arvin. Beautiful bow. Remember to get a full draw when you take it to the flight shoot. Would love to see the photo.

Well, its a tie right now among everyone who hasnt submitted a bow. So.... its neck and neck,, and anyone's game!

   I'm still finishing my latest frankenbow, so it might be a February entry.  Or March, at the speed I get these things done.

CONGRATULATIONS Arvin on winning December bow of the month!
