The first two pictures show the installation and completion with the patch in place on the airplane. The third picture shows the patch after the canopy has been removed. I have decided that although this worked well, I will attempt to redo this patch. I put the patch on the outside and the backs of the aluminum rivets are in oversized holes up against the plexi. I will move the patch to the inside with the heads on the outside with 1/2” aluminum washers between the heads and the plexi.
The last picture shows what I found in the other drilled holes after I removed the canopy. It turns out that there were two other holes that had cracks developing in them as well - one of which is shown. That meant I really had three cracks in the canopy.
