That guy's videos are pretty cool. Watched his full cnc machine build yesterday. A lot of things came up that I hadn't really considered, and the accuracy of his build seemed pretty spectacular.
I'm a bit worried that I'm totally mental, but I'm wanting to build something moderately massive and cut full sheets of ply, and as such the accuracy doesn't need to be as good, but it seems like the hardest part of my build is going to be building a flat enough stiff enough table for the full sheet.
