CNC Plasma Cutting Chassis

[GilaMonsterAlex]

Set up is everything. It's not just about drawing a hole and some lines that will make it work. You need your plasma cutting machine to be setup correctly for your material of choice. If you learn that, your cut and part quality will make it worth the effort.

I would not plasma cut small holes. You could "mark" by blasting the center, this doesn't always work!

Plasma cutting aluminum is very doable. It does create lots of "slag" that sticks to the aluminum, more than steel slag does. On sheets you won't notice it, but in tube or u-channel it will stick to the walls. I find that a twist lock scrotch pad will take that stuff off real easy. Otherwise it's a pain.
