Completed the canopy frame riveting. Most of the rails can be squeesed vs bucked which speeds things up a lot. You keep measuring for twist which is tough as the frame is not too sturdy even when assembled. The canopy plastic gives the final rigidity to the structure, but I am happy as it holds within 1/10 of a degree with no manual twisting of the frame. The frame is sitting on the fuselage and will get attached to the mounting brackets in the net session for checking of the mechanism.
