I took the canopy frame off and laid duct tape on the side bows of the frame. I positioned the frame on the bench and placed 2x4 blocks on the outboard side of the bows. I applied a clamp to the blocks and attempted to increase the arc of the aft corner. I didn't apply enough pressure, apparently, because I was not able to bend the bow.
