I’ve been thinking of proof-of-concept materials for a frame I’m designing. I don’t want to commit to using steel tubing at this point, and the frame I’m designing has flex built into the overall design. So, I’m thinking of using bamboo or graphite fishing rods, cut to size. My design compensates for twisting and warping of these lighter weight materials. For a concise overview of fishing rod creation, click here. While cost and time are factors to consider, getting my ideas into concrete form takes precedence. For the drawings, I’m using PowerShape-e, Delcam’s free 3D autocad software. It’s got a great user interface with intuitive controls.
