I realize you're after a bulkhead, not a spinner. <<
I've made several fiberglass spinners and even a front bulkhead or two,
but I've always had an aluminum "main spinner bulkhead" (the aft one)
between prop hub and spinner, and I agree with Joe, an aluminum bulkhead
makes you sleep a lot better at night. That aluminum bulkhead is the
perfect starting point, and the one I've been using included with a
Cessna 150 spinner made by Aero-Fabricators in Lyons, Wisconsin, part
number 1-340-100, sold by Aircraft Spruce, I believe. Use the bulkhead,
use the spinner for a mold for a glass one, and it worked great for me.
Making new fiberglass spinners is not unusual when you "fly" like I do.
I've never lost one in flight....it always seems to be asphalt or sod
that does them in.....somehow. I've used the original spinner as the
mold several times, because the aluminum spinner itself was a tad out of
balance, or at least my implementation of it was. Fiberglass and carbon
fiber are so light that any imbalance due to material overlap isn't even
noticeable. The bulkhead has survived all the calamities , at least up
until now.
