I have a project (tornado shelter) where I will be cutting down ten 4'x8' sheets of 14 gauge sheet metal to various sizes.

I have considered:

• electric shears
• wood framing circular saw (just buying a metal cutting blade)
• metal cutting circular saw.
• paying a sheet metal shop hundreds of dollars to shear them.

Regarding the option of circular saw with a metal cutting blade, or a metal cutting circular saw, does anyone have experience with this? how many blades would I go through while ripping my ten sheets?

Thanks in advance.

By the time you buy items 1-3 and associated blades and spend all that time doing it, a sheet metal shop can do it in a couple hours and everything will be cut nice and square with a shear. Cutting it with a saw will also leave a lot of ragged edges that will take more time to smooth.

My experience: we have a sheet metal shop and 14 gauge is not as easy to work with as you might think.
