Hi, I am in the middle of replacing my canopy. I have searched the archive, and find no info on how to bond a bubble to the frame.
I have inherited what I think is an original kr2 canopy, and a GRP frame. the GRP frame has a flange that will sit inside the bubble, ie the screen will be bonded on the outside of the frame. The flange is approx 1/2 inch wide, and isn't a brilliant fit with the shape of the canopy, it looks like I will have variance is the gap between the flange and the plexiglass - of perhaps up to 1/4 inch in places. Without too much difficulty I have made the frame fit, and I have cut the canopy to shape. Having spoken to a professional plastic sign maker, and then googling, and some experimenting I found that I could cut the plexiglas with an electric jigsaw using a vey fine blade and water spray to keep the blade cool. I am told that you have to do it in conditions of > 20 degrees, and you must make sure the plastic is well supported. What I am unsure of is how to bond the plexiglas to the frame. I have been looking at using the sort of mastic that is used for auto screens, but no idea what it is called or where I can buy it. Also is it considered necessary to use screws to further secure the screen in position. The final conundrum is how to hold frame to bubble whilst the adhesive cures, I had thought about drilling small holes every 2 inches and using fishing line threaded thru the holes to kinda stitch it in place, but I suspect lots of you guys must have solved these problems, so your ideas and help will be most greatfully received.
