Looking at that pix, I see the same flexure as you in that lightweight gantry riser. That is not even remotely close to being stiff enough to carve steel. Even alu would need light cuts, and a fractional pause in the corners for that to catch up IF the tool is sharp. But in alu, the tool is not going to stay sharp long enough to matter if not doing it submerged in an oxygen displacing bath (water based is out), or drowning in a directed mist of oil such as safflower cooking oil (for its higher flashpoint). Either one presents itself as a messy affair. BTDT, several times. Nice job when done but the cleanup? At the end of the job, that 2 oz of safflower oil was a fog in the shop with about a 20 foot estimated visibility range and all over my glasses not to mention the air I was breathing. :( > I find it hard to understand how you weld up your own frame and get it > flat and square, unless you have the right tools to do so. > > I cut a lot of 12"x12" material into little pieces, so flatness and > rigidity is quite important to me.
