 |

Listers,
I've been working on my canopy and it's driving me nuts. I got the tube frames to fit the curvature of the bubble and I've been trying to line everything up perfectly before drilling any holes. I must have spent over an hour trying to get the edges on both sides of the bubble to line up with the same spots on both sides of the frame. I finally realized that the canopy bubble is not symmetrical. The length of the bottom edge on the right side is 1015 mm and the left side is 990 mm. Has anyone else encountered this problem?
Obviously there is no way to line this up evenly on both sides so now I'm wondering if I should trim off the lower half inch on the short (left) side. Since the front and back of the bubble angle outward, trimming it in this way will increase the lower left edge length to equal the 1015 on the right side but I'm afraid that I may screw up the symmetry of the bubble curvature and create some other problem. I hate to waste an entire weekend of building time waiting until Monday so I can call Zenith. Opinions?

I had to do some trimming on mine to get it to fit. I think I trimmed
a bit off the bottom of one side but I also did some trimming front
and rear to fine tune the shape to match the fuselage and to get just
enough gap to get the rubber molding to fit. I used a pencil grinder
and ground it down a little at a time.

I'm not there yet but I did run across this idea and thought it had lots of merit.
