Working on the rear turtledeck now. The former at the rear of the canopy is sloped, so I had to use some maths to get the right shape for the former's curve. On the right is a circular arc, and on the left is what shape the former needs to be to so that the turtledeck's curve remains circular with the sloped former.
I'm using the water soaking trick that a few of the guys have kindly mentioned on this thread. I soaked the balsa in warm water for 10mins. Now it's rubber banded in place while it dries out to hopefully get it to hold it's shape for when I glue it later.
