Trimmed the bottom edges of the front bubble and dressed them up with 120 grit sandpaper. Riveted the bubble to the canopy rails and added the front and rear hoop gussets. I had to hop in side the the plane to rivet the brackets on. Thats my excuse and I'm sticking to it.
I'll add a soft rubber seal to the rear bubble for the joint flashing to compress to give a good seal
