On a different note….. Shredd… I have a shooting machine design that you may be interested in for your testing venture.
I worked out the design with an engineer taking a hooter shooter and incorporating a tension meter , an integrated measuring device for exact draw length, and an interface software with excell to automatically upload the full DFC chart as the bow is being drawn, then uploads the speed from the chrono and inserts the bottom line.
It’s a pretty cool design…. Runs about 2K to build. Kirk
