Not true. A CO2 laser is indeed not too difficult to scratch build but
metal cutting requires considerably more power than any homebuilt I
have seen. The 400W ferranti laser I had a look at was the nearest
thing to a homebrewable metal cutting laser I have seen and it was
huge and the power supply was even huger.

Forget it for metals.
