RV-7 N890GF

This weekend I spent time preparing to bond the canopy to the frame. I needed to finish the canopy latch mechanism installation. I decided to modify the design slightly based on some builders logs I’ve read.

The latch is installed with a spring and washer that prevents it from being rotated and locked unless the handled is pulled down. This should prevent any accidental locking of the latch when no one is inside.

Here it is in the locked position. I’ve also added some UHMW plastic on the underside of the roll bar to protect the metal.

Once I finished the install I got to prepping the roll bar and frame for the Sikaflex glue that will be used for bonding.

I masked the whole roll bar to prevent glue from accidentally sticking to it. I’ve added some 1/8” spacers to the top of the bar in order to ensure the proper gap between the canopy frame and the canopy. These will hold the canopy up the required spacing above the frame. The frame and the roll bar are perfectly level with each other, so this will ensure an even gap and the appropriate amount of glue.

I then clamped the frame to the roll bar with the proper spacing blocks between the two. I also added side rail clamps that will hold the canopy in place when the glue cures. Now that all the preparations are in place I can get the canopy ready to bond.

I also ordered some foam and leather from Classic Aero Designs, the company that made the rest of my interior, in order to make an armrest.

It’s the first time I’ve worked with leather and foam like this, so I may attempt to redo it, but its much nicer than resting my arm on solid metal. I have enough material to make two more if I find the desire to remake it.
