6061 Aluminum Sheet Spinning
I have been talking with metal spinning companies and understand that it is best to use hot rolled steel for machining the mandrels for spinning multiple 6061 aluminum sheet blanks. I have the profile template cut for the machinist to lathe the mandrels and hope to have them perfected by next February.
I need 12-47" length x 10-1/4" beam (at the widest section) radio control submarine hulls.
I am understanding that the hull should be made from 4 metal spun sections and then butt-welded together to achieve the full length.
The finished minimum wall thickness needs to be no thinner than 3/32".
I plan on hard-anodising the hull in black.
I welcome all and any constructive advice on this subject.
Regards,
John
