I did a little re-taping as the interior painters tape is not as sticky as the exterior tape, so I used that in addition. I also cut the cardboard insert to get ready for the big cut. In order for the canopy frame to seat well against the cardboard and the windscreen support, I took off the spacers that were in the way. EAA meeting tomorrow night so Wednesday night I plan to cut the sides and maybe then I will be ready to make the separation (big) cut.
The idea is to use the cardboard as a line to make the big cut. Getting closer.
