Fitting the slider canopy to the frame. At the rear center line the
plexiglass appears to flare upward for a distance of approximately 2 inches from the
inside ( toward the front ) of the rear mold line which is 3/4 inches wide. It
would seem that if the canopy were cut anywhere in this upward sloping area it
would cause the aft skirts to angle upward and away from the aft top fuselage
skin rather than rather than conform to the taper of the aft fuselage.
Any advice on how far forward of this rear mold line to cut will be greatly
appreciated.

Dale,
I clamped some scrap aluminum angle (about 5" or 6" long) on the top of the
unwanted curved area with an equal length wood block on the bottom. I used
short enough pieces to keep the slight curve you want to remain in the
side-to-side direction.

I then heated the angle and plexiglass with my heat gun (must be hotter than
a hair dryer) and was able to bend the unwanted curve down to make a good
transition for the skirt. After removing the angle and wood, I sanded the
area to take out some small irregularities that the edges of the angle made.
I was surprised how much heat I had to put on the angle and plexiglass to
make the plexiglass soft enough to bend.

It worked great.

God luck,
Jon Byrum
