I have access to the CNC equipment to create male (or female) dies for nosebowls for a couple of pre-war Aeronca projects I own. In addition, I have acces to a large hydroform press. What I don't have is any practical knowlege of the hydroforming process, particularly for large complex shapes which require shrinking for the major "bowl" shape of the nosebowl AND stretching for the air inlets.
Questions which come to mind are:
How do you deal with springback?
At what point do you need multiple dies?
Does anyone know of useful how-to resources for this kind of thing? BTW, I saw EAA's video on hydroforming small parts, but I assume the degree of difficulty for something like a nosebowl is much higher.
Thanks for the help.
