I pretty much had all the aft canopy holes marked yesterday. I wasn't happy with how I had laid out the aft portion so I remarked everythign using 2.5 inch spacing. It was easy enough because I had it mostly laid out anyway. Hadn't planned on drilling tonight but there was nothing left to do. I put a couple pieces of duct tape on each side at the rear to pull it foward to the forward canopy. The thickness of the tape caused a gap but I don't think it will be a problem because theres a lot of flex in that portion of the skin. The plexi bit did a fantastic job. I went slow and let the bit do the work. No cracks anywhere.
