I have a glider, a canopy frame, and a new plastic canopy, and now my problem is making them all come together into a functioning unit. I've searched this site, and found a bit of info, but still really need some detailed instruction on fastening the plastic to the frame. I know the frame has to be fitted to the glider first, and the plastic cut, fitted, and glued to the frame, while in place on the glider. I understand that screws aren't necessary, and may in fact cause trouble. I think I need a fine tooth circular saw, and grinder, some way of clamping, a specific adhesive and info on how to use it. I can't do any of this, but will be working with an experienced aircraft engineer, who is willing to give it a try. Any help from this community would be appreciated. Or pointers to some place or person who can assist. Thanks, Guy Kestrel 19 CF-FGR

If you can get the direct assistance of someone that has done this properly before, you would be well advised to do so.
I trim canopies with a disc sander and would NEVER use a saw due to the liklihood of starting cracks.
I use screws with large washers on the perimeter to hold the canopy flush when gluing. No holes are drilled in the plastic.
Most all canopies on glass ships are bonded with epoxy like that used for repairs.
Good Luck
