This is a design for a 2 axis compound bow balancer. It is intended to completely balance the bow at the grip point. The base can be attached to a work bench with either a C-clamp or with No. 6 pan head wood screws. Both axis can be locked in order to balance in one direction at a time. Once the clamp is secured around the bow, the clamp is snapped into the yoke and secured by tightening the two machine screws that run through the nylon rollers. This design has been prototyped but has yet to be tested. The modeling was done in FreeCAD and the source files are provided.
