More clip wing project photo's from Steve Robinson as seen on the Facebook Monocoupe Aircraft Group:
More Clipwing photos. The control stick fulcrum was badly damaged at some point. It was twisted and poorly repaired. I decided to cast a new fulcrum. I drew up a new drawing in CAD using the original print for reference and dimensions. Once in CAD, I enlarged all the dimensions by 6 percent to account for shrinkage in the foundry process. With the new dimensions I fabricated a master of the fulcrum in a proto-typing tooling material called Ren Board. Then off to the local High School that has an aluminum foundry in their metal shop. After a couple of tries, I had a good part that was then drilled for bronze bushings and finished on the outside to proper dimensions. Then bead blasted to a smooth finish.
