I saw that when I was researching to build my mill. I though it was cool before I knew what I know now. Lol It works for him since he is only milling small furniture stuff once in a while. looks like a waste of a golf cart. All he did was ghetto rig the drivetrain.(motor trans axle) onto a carriage. He bought and used a bunch of steel anyway. Other issues are fps or blade speed, tire size vs. Band durability, limited depth of cut etcetera etc.
Lol lots of good in theory ideas, produce crappy results. Obama care for example. Lol. Waiting on Jesus
