Sanded yesterdays cowling work. Trimmed flanges. Added one bid over oil filler hole on plenum to try to mark where oil fill tube was so that I could later close the gap between filler and plenum. Painted inside of lower cowl with epoxy to seal against oil,fuel,etc intrusion.
The heater control bellcrank is to be mounted on the rudder bellcrank cover. I decided this needed reinforcement. I add a layer of triax to the top and CP side if the cover.
