cutting stainless steel

I plan on covering the firewall on my 32 Ford with mirrored stainless. I have to cut it to fit and want a smooth edge when finished. The edge of the stainless will be exposed after I attach it to the firewall. What is the best way to make a good clean cut that looks good?

bct,
How thick is this stuff oing to be? Do you know the gauge size?

On thick stuff you could use a saber-saw with a metal cutting blade. But the edges will need to be filed.
On think or thin you could use a plasma torch(aka "the wonder torch") again the edges will need to be filed or ground with a sanding wheel.
On thin stuff you could buy an air powered hand shears. They work like a pair of scissors but the air makes it easy on the hands. This will not do very tight turns so you will want to drill holes where you need to turn. You may need to smooth the edges with the power sander also.
Stainless can be a pain so go slow.
Have Fun

A cutoff wheel in a die grinder will give you an edge that will be stress free from cutting with shears and is much less likely to scratch the surface like a saber saw. The edges will need to be dressed and polished but this can be done with a block and fine grit wet/dry paper and WD-40 as a lube. Start with 280 grit and work up to 12 or 1500. It won't take much to put the final polish on it...

The Scotch-Brite™ SST Deburring Wheels are what I use at work, they are basically an abrasive impregnated fiber wheel that is sturdier than the layered Scothcbrite types so you could do edge blending without cutting the wheel into pieces. If you use the medium or fine grit you can go straight to a polish finish with just a buff and some compound. The wheel is strong enough that you can remove material with it.

Just my opinion but iI think shears would be your best bet. Next would be a sabre saw with a fine blade. After that I would use a plasma cutter and a cutoff wheel as a final option. Mainly because a plasma will leave a little slag and a cutoff wheel takes a little more hand control than a sabre saw. But no matter which way you go, cover it with masking tape to protect from scratching.

I'd use a bandsaw. It will cut without distorting or coloring the metal. I use a bi-metal blade and run the saw very slow it works great. If you are around Santa Rosa, Ca. bring it by and I'll cut it for you.
