EDIT- this thread started as a 'How I made ten inch diameter, ogive shaped nosecone, out of.....posterboard, a PBNC....' but I may as well show you what it's for! I'll pick up the edit in the next post.
PBNC as in... Poster board nose cone
I've previously made a 5.25", 2:1 ogive

This is intended to be a 10"x26". Iirc that makes it a 2.6:1 ogive?
I had a thread on the 'tool' that I eventually made to cut out the transitions, that worked out quite well.

There were supposed to be 11 transitions, but the largest had a 17+foot radius that would have been...difficult..to cut.
The two largest are 3" tall, all the others are 2". They will overlap each other by about 1/4" or less. The ends were left long, and I will trim as I go.
I've started at the top, and am working my way down. I'll glue up each transition after double checking it with the next one.
So far, no glue, it's at 81 grams
