Fitted in aft bagage compartment bulkhead at an angle for more fuel capacity. Used a piece of cardboard to fashion a template for the longtidudinal slanted bulkhead. Had to allow this bulkhead to seperate from the forward part of the fuselage due to geometry and surface complexity. It is ok because it will simply add a little more baggage capacity at expense of fuel.
Fashioned forward bulkhead by door beam from scored 1/4 inch divincel. Used tongue depressers and hot glue to hold curved shape in place till glass is applied.
Overall, after sitting in the airplane, I am very pleased with this arrrangement. Still hoping for 40 gal/side
