Continued to work on some more unfinished items. Completed riveting of the top longerons. Also installed spring on canopy latch system. Drilled out the side frame handles for the canopy. Marked the hole placement for the side frames. Prepared front top skin for drilling to final A4 size holes. Painted the rear tube mounting brackets. Hopefully wieather will cooperate and I will be able to paint some more parts tomorrow. Still waiting for warmer weather so I can safely work on canopy bubble. Temperatures still in the 60's.
