I cut 12 more sheets today two copies each of R1-R6, which start the taper down behind the high point of the roof. The hinge for the hatch door is about a foot back from this point. I'll glue more tomorrow if it doesn't rain; because I have to do it outside, or I will have to very soon.
I now know what a dull bit does in XPS foam -- it melts it and flings it off in all directions! I had to pick the bigger bits out, and I think the piece it happened to be cutting will still be usable.
