I would be in to help with this too. As a matter of fact, Just to keep my cad "chops" if you will, I started to draw up a scaled down mach1 for .40 for .46 size engines. Drawing hasn't stalled out on them just appears to be some unique challenges in the design i'm working out. But yeah I would love to be a part of this effort. Tipo .46 plans are done and will be starting construction in the fall. Phil
