I got my plans in 2009, the lines were nice. The "blue prints" seem to be general guide lines not really perfect or exact. I made a tracing off of the print..then made a wood template, using the template I cut out form with my band saw, then trued it up with the template and a 2" long pattern bit on router table. I kinda changed the design a little. I tightend up the hook a little..and narrowed the limb tips more than the print
