Such skins aren't necessarily stretch-formed. They
can also be done using English wheel and hammering
or bumping. Dick Schreder used relatively low-tech
hydroforming to make the compound-curved forward fuselage
skins of the HP homebuilt gliders.

Thanks, and best regards to all

Here is an article that Bob wrote several years ago describing Dick
Schreder's system.
