An experimental leaf-spring lever bow

This sure is something different!
Really like it!

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.
