1. I took a look at the canopy and how it rested on the frame. There didn't really seem to be any way it would lay down over the rear part of the canopy rail, regardless of how many clamps I used. So I unclamped everything and slid the canopy forward about 1/2". Bingo. The canopy could now be clamped along its entire length with just a reasonable squeeze. I decided to re-notch the bottom edges of the canopy to clear the vertical tubes, then see how it fit. 2. With the help of my friend Jim, we removed the canopy, re-notched it, and re-clamped it three or four times. The canopy seemed to be happy in its new location, so I marked it from the inside for trimming. 3. Since the canopy was moved forward 1/2", the forward edge now extended too far forward on the forward rail of the frame. So I marked it for trimming, too. 4. We unclamped and removed the canopy from the frame again, and placed it upside down on the padded work stands. I taped a dowel rod across the wide end to keep the canopy stable, and taped it to the stands. Then I trimmed off the bottom and front edges of the canopy. Because of the body and hand positions required for this operation, and the approximately 16 feet of cutting that had to be done, it was one of the most back-breaking tasks I've done on the airplane yet. 5. Used a sanding block and a mini polishing wheel to start smoothing all the edges. There is some more to do, but for now the canopy safe to move.
