The canopy turned out to be significantly easier than I had anticipated.And although I make every attempt to not use CA adhesive, it made this assembly neat and strong.
Two templates for the canopy can be taken from the plans.The first is a profile former, which will form a “spine” on the center of the fuselage, and, the second template is the top of the canopy.After the former is traced from the plans, two adjustments are needed.The top of the former needs to have ¼” removed from the top, and 1/16” from the front.
The top is made from ¼” stock cut to shape, and its’ sides sanded to an angle such that when the canopy sides are installed, they will have some area that is flush to be glued.The profile former and the top are glued in place.
The canopy front and sides are made from four pieces of 1/16” balsa.The templates for the front section were made by taping paper to the former and top, slowly creasing the paper with a fingernail, and cutting away what doesn’t belong.Note the grain direction of the front pieces on the photos.The two front pieces were joined and the bottom edges feathered prior to gluing in place on the plane.A bit of water was used to encourage bending.
The two sides pieces were cut from templates.If I had do make these pieces again, I would run the grain vertically, rather than horizontally as shown in the photo.There is a slight concavity to the sides, and although it looks cool, it wasn’t what I intended, and will be difficult to finish both sides of the canopy evenly.
A piece of tape marks the line where the sides need to be cut, and the bottom edges of the sides are also feathered.
A judicious amount of filler, and done.
