glider canopy

Depends on how much material needs to be removed? If 1/4� or less needs to be removed, I use a 6� rotary hand sander with 60 grit disc.. If more material needs to be removed, I use a 3� carbide disk and then trim to final fit with disc sander. I sand the inside of the canopy that will be glued down, with 40 grit sandpaper to give the bond tooth! I use epoxy with chopped cotton to thicken the mix. I mask off both sides of the canopy and hold it in place with 3 or 4 bungee cords + small wooden blocks at areas that don’t want to lay down flat. Mask off the fuselage side, also..........a few minutes spent in preparation will save hours of re-do! Fill and sand until you get desired fit, then re-mask the canopy out about 1/8� for final painting. Recommend canopy be glued on with shop temperature about 65 degrees Fahrenheit, so that canopy will close on the ramp when it’s 100 + degrees and still won’t leak too much when the temperature drops below zero degrees, in that wave you stumbled upon!
Hope this helps,

Oops, forgot somethings........ slip 1/16� shims between canopy rail and fuselage, front and rear, then close and lock frame to fuselage! This gives the needed thermal range 0 to 100+F. I like to use a small guide post at the rear, so that I don't end up moving the gooped-up canopy. I paint on resin to the inside of the canopy and trawl- on cotton flox’ed goo on the frame. Schleicher uses a thin strip of foam tape to keep the goo from oozing out onto the inside of the canopy! This is definitely a TWO MAN JOB!
