Cutting .063 4130?

[Mike Switzer]

I prefer a plazma cutter for everything but the simplest of cuts.

I agree, but they are pricy if you won't be using it a lot. I paid over $1200 for mine back in 1999, but I use it quite a bit for auto body work. It also came in real handy for trimming the ends off all the steel studs for my apartment/office/shop that were a bit long.
