After a many-month wait, and some false starts, I finally received my canopy! It was made by the same company that manufactures the canopies for Van's Aircraft, but it has a few differences. It's made of a slightly-tinted, UV-blocking type of Plexiglas. I also had them make a custom front windshield that has more slope than the a stock one, and is also thicker. The first canopy they made had a small defect in it. They asked if I could live with it, and after looking at it, I decided that I simply couldn't. Hence the delay. Now I've got the canopy I wanted. Unfortunately, it's now the dead of winter -- not the best time to be cutting a canopy -- but I'll see if my new hangar heater can get the shop up to 75 degrees. If not, I'll just wait a couple of months before working on the canopy project.
