Alternatively, you could put a ferrous metal cutting blade in
your worm drive circular saw. Note that non-worm saws don't
have the mustard for this kind of duty.

NON-optional safety gear

* Use hearing and eyeball protection! This is not a
quiet operation but it is a little cleaner than a
chop saw.
* Use gloves!
* Use long sleeves and protect yourself from high -
velocity steel swarf.
* Lubricate cut with wax

It works surprisingly fast and leaves a straight non - HAZ cut.
