anyone have any experience with fabbing a large spinner; say 16" od and 18 "
long?

I made one for a Soob in a Glastar, using 5052H32 and cutting two
circle segments that I rolled and riveted together. Could have done it
with one piece but a single rivet line would have imbalanced it. The
aft bulkhead was formed from the same stuff over a plywood template,
with notches to allow the compounding (see a 172's spinner backplate)
and the front mounts were welded steel brackets that bolted to the
blade bolts of the Warp Drive prop. It ran fine, still does.
