Do yourself a favor and play devil's advocate with your next Google search, there are many, many reasons not to do this. Before modern tire tech (pre 1970's) this was common and needed. Now it's only done for race cars, for traction, not balance. Wheels are often not centered on the hub when mounted, so the only way to 'true' them is on the vehicle (as in your Ford video) but the moment you loosen the lugs you throw it off true again, only with less tread now. And of course with any homemade device, you're more likely to screw the camber up than get it right.
