So I do not have a plasma cutter, and I am not spending the cash to get one. I do have a Sawzall, an angle grinder, a die grinder, a chop saw and Rage cold saw (both of which really would not work well to cut chassis plates) and a hacksaw.
What are the most wise group's recommendations for cutting plate steel (3mm and 6mm)?
Thanks in advance!
Cutting steel in a straight line is not difficult. I have cut up to 1/2" over 8 or 10 " long with my 7" angle grinder. Make first a shallow cut over the whole length using if you need it a metal fence ( I don't) and go over your cut several times until the disc cuts through. Actually I prefer the angle grinder over the plasma cutter which I have. When it comes to curves, this is another story. Sawzalls, jig saws don't like turns. There I try to use hole cutters under the miller . If you don't have one, the drill press would do. You can cut up to 6" circles in 3 or 6 mm (or a lot more) and use these curves to form the parts for your car. And if all this does not work, yes you need a friend with a plasma cutter or someone with an acetylene torch.
Good luck
PS. Mgkluft below is right: try to use your band saw. I use mine up to 6-7 " lengths (it take longer, than with the angle grinder though)
