DG-505 cracked canopy repair

[haven]

Any suggestions for the repair of a 10-inch crack emanating from the
aft frame member top-center along with a 4-inch crack 3 inches below
and 3 1-inch cracks spaced 1 inch apart further down?
Does anyone have a repair manual with instructions?

thanks, Haven

Just search this group for "canopy repair". Lots of threads and
suggestions.

I never had much luck repairing cracks, but you can stop the
progression with a red-hot piece of wire shoved in just ahead of where
the crack stops. I have used a straightened out paper clip held with
vice-grips and heated to red-hot with a cigarette lighter, then shove
it right through the plexiglass about 2mm ahead of where the crack
stops. This method sears over (melts) the plastic and does a good job
of preventing crack creep. Canopy repairs are legal as long as the
crack isn't in the pilots view when landing.

I read a great article in an EAA magazine on how a guy fixed a B-17
top gunners turret bubble canopy that was extensively cracked and had
missing pieces using
a product called Plastifix.

This stuff looks like just what you need as fixing a crack should be a
breeze and produce excelent results, plus it is not expensive as a
bonus.
