Hi Al,

Thanks so much for the thoughtful response. As a newbie mentor, your help is greatly appreciated.

The only parts that I made, that touch the composite bow limbs, are the "limb pockets" parts:
  1. Delrin guide/spacer for adjustible tension
  2. Ball socket (1/2 sphere washer) for bolt pivot point

If the shooter works well I may order OEM parts to eliminate doubt about the limb restraints.

I have been scrambling to get developed enough to test accuracy. If the performance pans out, I intend to make shop drawings and write up my analysis for review. Sorry I don't have this ready now...
