Where did you get the extrusion for the duke frame spars? What grade ally is it? Did you just make a form and bend the spars in a press?
Making my first swinger at the moment. One day i hope to build my own frame. I'm using 6082 as i cant afford the min quantities of 7020 you have to buy. That stuff is hard to get hold of! I've found the 6082 bends ok if you warm it first. Unfortunatly doesn't have the self hardening properties of the 7020 so i might end up building an oven to bake it in.
yes i make all my frames out of 7020 ,the extrusion is the same material as spondon made the norton frames for spray and nation out of ,ihave some left ,6082 isnt very good because after welding its like chewing gum , there is another alloy that is like 7020 that is available ,i make my plenums etc out of it and all my other parts that i weld,that regains 90% of its strengh and you can buy in sheet and plate, if you heat treat after welding unless you have left all bores and brackets etc undersize and then machine after nothing will fit and frame wont be straight ,because of the movement with the heat
