FYI, I stumbled across this thread in a search and decided to work from the information presented. I recreated the dwg shown above by pasting the graphic into AutoCAD and then tracing over it (more or less...the numbers don't match the actual line dwg). Then I exported it to a .dwx file and sent it to Send Cut Send for a quote. They'll make 4 of these out of 1/2" mild steel for under $40 (including tax and shipping), which is HALF what the Ebay sellers are asking for these nowadays. I did have to move the 1/2" dia hole a bit inboard on both axis, to accommodate SCS's waterjet limitations, but I think that's probably a better design anyway. I also changed the tips to 3/8" dia round curves, to match the factory indents on my Matthews Phase 4 limbs.
