Gathered the parts for the canopy system. Measured, drilled and assembled the framework to hold the bubble. Installed the hinges to the frame with much trouble. When they were welded to the fuselage they warped and made it very difficult to operate. This item took a lot more time than I expected, as there is a lot of fabrication here. I'm doing the emergency canopy deployment system. (not that I intend to jump out of a perfectly good airplane).
