All Together

I'm very happy with how it all turned out but need to hurry things along in order to catch up where I am with it today.  In addition to being able to sweep the limb angle through a very wide range, I can move the limbs in and out and adjust up and down to fine tune tiller and string tracking issues.  The possibilities are endless.  I imagine I could find myself endlessly tinkering with these adjustments too so I don't know for sure if it is a good thing yet.  Hahaha!

Foot Bow Limb Riser Assembly

The adjustable limb angle allows me to easily and gently string even a very high draw weight set of limbs with little more than a ratchet and socket.  I love it!  No bow presses necessary.

Frame

I have very limited machining tools, so the design of the frame for the bow had to be simple enough to be made with little more than a drill press and band saw. The top and bottom plates are 1/4" thick aluminum plate.  I simply drew up the outline and hole locations, printed it out, and pasted it to the plate.  After a little careful drilling and some tap-and-die operations, it was pretty much complete.

Top and bottom plates

The limb pivots are made from thick wall steel tube that is drilled and tapped for a 5/16" cap screw.  This allows the limbs to pivot and provides a very large range of limb angles.  It will probably make more sense when I show how it all goes together next.
