No I have not tried annealing, allthough I know of the method, and it has been disscused in the forum I belive.
I have today bent my U/C, I used a couple of bits of angled Ali in the jaws of a work mate, then with a block of wood, put some weight behind it. Tried it on some scrap first and all seemed OK. There is some stress marking to the Ali but as the angles are not that tight I think all will be OK. We shall see. I still have enough Ali to make 2 more!
I have tried to include 2 photos of the operation, please excuse if things do not go right as this is the first time I have tried including photos.
