I'd say anyone who's even vaguely familiar with what it takes to operate a fabrication BUSINESS would instantly recognize the fact that this guy has essentially none of the equipment that's necessary for doing such work on a competitive basis.
I've been in the metal mangling business in one form or another for 45 years. My primary business is cnc and manual machining, but I also do some one off fabrication projects from time to time. For fab work I have a shear, box brake, leaf brake, press brake, mig, tig, and stick welders, powered and manual rolls, large and small bead rollers, drill press, beverly shear, hydraulic angle shear/notcher, horizontal band saw, vertical band saw, 15 ton turret punch, and an assortment of small metalworking tools, both manual and powered.
A couple things in the above list are handy, but you could get by without them in a fab shop. The rest are what I'd consider the bare essentials for doing the work at a price the customer is willing to pay.
Per this guy's website and videos, he's got a band saw, a jig saw, and a couple welding machines. Yet, he's soliciting work at $145/hr, which is roughly twice the current going rate. No wonder he's got time to spend endless hours making carts and over-complicated welding tables and keeping everything looking as if its new and unused.
And, FWIW, people in business don't use Rong Fu mills and such because they don't have the time to waste nibbling on stock at a snail's pace. Stuff like that is fine for home shops where time is immaterial, but you'd starve to death trying to make a living with it. Using equipment in a business that's not up to the task is no badge of honor or statement of skills. More like ignorance of what's required to do the job. The cost of that Rong Fu plus the $2500 wasted on a piece of stainless plate for a welding table top would've paid for a decent used Bridgeport that'll cut more metal in an hour than the Rong Fu will cut in half a day.
