    o.k., looking at the plan on page 1 and having build myu own jig i would suggest adding 3 cross support throughout the length of the jig along the bottom.

    you could use 1/4" x 1" flat stock which is cheap and 6 bolts. all in all, it would add another $5 to the cost of the jig. it would also guarentee that when you come down with 12 tons of pressure the jig won't bow out.

    my $0.02

    I think you will be better off using a small stock.

    correct me if i'm wrong, but isn't the rear of the receiver supposed to be slightly wider than the front? also why not use some pipe as spacers between the two pieces of angle iron instead of nuts?

    Width is constant.

    My first attempt at bending a flat showed evidence of the jig bowing in the middle causing the middle of the receiver to be slightly wider than the front and back closest to the bolts.
    Someone correct me if I'm wrong, but isn't it standard procedure to compress the sides of the bending fixture in a vise after the flat is pressed into it? Since the outside "shoe" of the jig is going to bow in the middle, the vise should squish it back to where it's supposed to be, tight up against the inner jig. This solves the bowing problem in the middle.

    Is this correct?

    That is correct, at least for the jig you have bought.
    What I have found is that by placing it in the vice and wrenching
    it down good and tight it makes the corners nice and square.

    You can still get a good bend without doing that, but
    it's better if you can tighten it down to ensure they are good
    to go.
