Five black spring washers, plus four large steel nails, two folds thus far (another four folds to go), shape, heat treat and dump in acid on friday.
I have another 2 x 2 wired and ready to weld, I think I'll just twist this one, and do no folding.
The fun is that the alloys weld first time, very easily (compared to some of the alloys I've played with of late).
