Not much progress today...just remembered to rivet the brackets which attach the support brace to the aft half of the canopy frame. If I didn't get these done before riveting the forward and aft halves of the frame together, I would have to use pop rivets to attach the brackets.

Here's the bucking bar my brother made for me.

See how it'll fit through the gap on the outside of the frame to allow me to drive solid rivets along the insides of both the forward and aft halves of the canopy frame? Now I just need to find a riveting partner to help me out with these 36 rivets.
