Cutting Sheet Metal

[89Suburban]

How do you cut a long piece of sheet metal in a very straight line? Can it be scored and snapped somehow? Or put in a home made jig?

I have regular cutting shears, just wondering if there was another way, or home brewed trick.

I need to cut those wheel arch panels. They are about 3 feet long, and I want to remove about 4 or 5 inches of the top of them. And I hate having a ****** looking edge.

I clamp a piece of 3/4" thick sheeting board to the metal and use it as a straight edge for my 4" angle grinder with a metal cutting wheel. Works better than a jigsaw or sawzall. When I was doing aluminum fascia for houses we would use a 10 or 12' metal brake, clamp it down on your marks and score it with a razor knife several times, then work the brake lever, bend the metal back and forth several times till it breaks. That was with aluminum though, not sure how well that would work with steel. If you had access to a metal shear would be the best way but it just all depends on how long of a cut you need to make. If you're cutting on your new body panels and they're kind of long, clamping the board on and using the angle grinder might be the best/simplest/fastest way.

So make a guide basically to clamp onto the metal, I got ya. I'll have to pick some cut off wheels up for the grinder.

Can ya borrow a cutting torch for the straight cuts and plasma cutter for the curved cuts? Saw saw might work too.

Read it. He can use grinding stone on drill to clean up those edges.

lmao or he could do what was already mentioned and have a nice and CLEAN cut that doesnt require you to remove ADDITIONAL metal to clean it up.
