Make the chassis from aluminium , but they also had a very basic form of bonded structure at riveted metal joints . A thin linen (i think it was linen) was bonded to the mating surface with the help of an autoclav . Now , how to do that in your garage is beyond me !!??
What the aluminiun spec is , im not sure but maybe 7075 as it is rigid but can be brittle as well , 2024 sounds like a better aluminiun to me , but im almost certainly wrong !!
Anyone know ?
