replacement panel shaping help needed

I didn't take auto-body in school......help a moron out would yas?

ANYWHOS.....how in the world do you get the 90* bend made on sheetmetal?!

IE: on the bottom of the tub, the metal has a 90* lip

for the life of me i can't figure this out......tried just lightly banging the edge of the sheet over a 2x4 block of wood......didn't work

Tried using pliers all the way down the length of the sheet......didn't work

What am i doing wrong here?! Is there a tool i can get to do this???

 

Sheet metal brake?

Probably need one a little bigger than this though:

that may very well be what i need......was scouring through ebay and they have 1 of these on there.

THANX!

 

I jsut clamped mine on the edge of the angle iron side of my trailer and gradually bent it with a hammer. A little hammer and dolly work to smooth it out and it looks just like the factory.

 

If you are looking for a brake, I would look around for a while for a used one. Watch for heating and cooling businesses that are going out of business and having an auction. In bigger cities you can check for second hand industrial tool suppliers etc. It seems that the prices of good used quality sheet metal equipment has gone up in the last few years. The demand probably being driven by all the "monster Garage" type programs on TV lately. Some of the cheaper brakes out there will only bend 20 gauge or lighter sheet. While you can sometimes fudge and bend heavier stuff, your bend won't have a constant radius along it's whole length. The brake simply flexes in the center and doesn't make as sharp of bend in the center then it does on the ends of the sheet. I guess it all depends on what you plan to use it for, but it is, as always good to get the best one you can as there will always be bigger jobs in the future.
