I put this on the Kalakala thread but I think it's better here as well.

Before starting the ally needs to be annealed, smear with edge of a bar of soap and heat until soap turns dark brown then quickly quench in cold water. This should be done whether it's a simple 90deg bend or working curves.

When working aluminium sheet to a curve a Soft Dolly "metal workers forming bag" usually made of leather is needed,  but modellers can get away with a cloth backed vinyl bag filled with sand a google search for metal forming bag came up with this Link.

A ball ended wooden mallet of about 2" is used to beat the metal to shape "I see in the link he uses metal hammers for a creditable job, although much harder to work with.

Annealing needs to be done frequently as the pounding hardens the aluminium.
