Balsa straight razor chopping block, perfect cuts

thingiverse

In building stick and tissue airplanes, I found I sucked at making good square cuts. This whole concept is adapter from an illustration on page 15 of "Rubber Powered Model Airplanes" by Don Ross (ISBN 978-0-938716-19-8). Full credit goes to him for the design concept. I added two 45 degree channels in the design as well. Capable of cutting up to 1/8" x 1/8" at 45 degrees and 3/8" x 1/8" at 90 degrees. Needed to complete: One straight razor, one medium rubber band.
