    Never tried it and never will but it's good to see how it's done.

    The first thing Newbies need to learn is that you can make any shape in metal by using five processes,
    Shrinking and

    The hard bit is working out how, when and where to use each of thes methods.
    Even with professional lessons it takes many years to become a master, so be patient, methodical and start small,
    Make an ashtray first, then try your hand a one off Boat tailed Duesenburg replica
    What I mean is learn the skills on manageable small jobs and then move up to bigger parts,
    and keep in mind that most large panels need to be hand formed in many small pieces that are then welded together,
    So many Newbies try to make an entire wing in one piece, and just end up quitting where a Pro would do it in five or six parts.

    this is so helpful, especially the bending metal with edges or flanges. if only id have known this 2 1/2 years ago, mind you the work i did then wasnt on my car, so im not too bothered

    a very useful thread

    Thank you Nobody
    I have seen your work and you make it look easy , I have used both way's to do tubs.

    I was not aware until I viewed Robs photo's he was building a rectangular tube chassis.
    I was picturing a stock inner panel that was being closed off. as would be a inner and outer wheel housing.
    Your way of doing the inner panel would be much more obtainable for Ron's application.
    With that said Let me show a very small piece I made , I have maybe 20 minutes in it so it's not perfect ..... :0

    Now see how the shape was obtained by stretching one flange and and shrinking on the other. I have done this on full size panels and it works well.
    Now Ron's application would not need both flanges but I just wanted to demonstrate the flange could actually be on both sides and still form a radii.
    Again with a rectangular chassis and a flat radius sheet, cut , and an edge tipped over in a buck would be far less work than stretching an edge to follow a radii....

    hi rob
    do the curve on the upright panel and not the tub.
    its so much easier.
    mark out youre half circle to size and then put the curve in.
    you can either hammer over a wood template with the curve routed in or use a hammer and a peice of bent tube held in a vice as a dolly.
    then fix this to youre rail and lay the rolled tub over the it slightly oversize for trimming and mark from below and cut.easy weld then grind of.

    if you put the curve into the tub it will become really stiff and youre have no play to open it out if need be to match the curve of the upright.

    nice tech btw mr prometalshop
