Brief Description: Heat Box Pilot Hole/Aft Top Skin Trimming
I located the position for the heat box and drilled a pilot hole in the firewall for it. I clecoed the forward skin in place, as well as the aft top skin. I drew a line on the aft top skin to outline where the canopy frame was. This will be a starting point for cutting out the top skin. I used a file to expand the cutout in the rudder pedal bracket for the firewall recess.
