metal working ?

I know this isnt a hot rod but i figure theres plenty of people who know how to work metal on here.
Im building a body for a oval track stock car and the companies that build them fold over the edge and make it flat for the wheel openings for the fenders and quarter panel about 1/4 inch i was wondering how you can do this on a curve like a wheel opening i will be working with .040 aluminum.
Thanks for any help you can give.....Joe

metal working

For folding over curved edges you need a easy edger and like similar tools under other names

Hi Joe,

You can tip a curved edge using a crescent wrench, or a pair of pliers. You should clean up the edges of tool so it does not mark the metal too much. Gradually tip the edge. Do not try to get the full bend in one pass. Once you get to about 45 degrees use a hammer and dolly.

Kent White has an excellent video called Edge Those Panels:

www.tinmantech.com

If you are forming a flange on anything but a straight line, you need to be aware that it can change the form of the part. A short flange like 1/4" will deform the part less than a larger flange. You may need to stretch or shrink the flange depending on what kinf of curve you are working.

Hammerform

One thing I just thought of is that a fellow can make a hammerform..say for example a fellow needs a "U" shaped opening fro over an axle he can cut a couple of pieces of MDF board to the u shape an clamp them on both sides of his sheet..then using the slapper tip the flange on to his panel..might work in this instance..

Not sure if this guy is doing a wire edge or just needs a flange..usually..least in my case only make those flanges just wide enough to catch another panel not more than about 3/8 or an in..

Once the panel is tipped and the strech is started then it can be carried over to make a wire edge..
