I guess I'll throw out my improvised method for dealing with the yoke nut.
The boot method should work great, but I can't use it since I don't have a lick of carpet in my house. Instead I use a very large (24" maybe?) adjustable wrench with about 4 layers of old T-shirt for padding. Wrap the reg body in the cloth and then put it in the wrench jaws. Sitting down with the wrench flat in your lap the jaws should be clamping the body from the bottom end with the turret facing away from the jaws and yoke facing up. Squeeze the jaws together from the outside while tightening the adjuster. This should hold the reg body good and tight without being tight enough to damage the finish. If you are trying to break the nut loose place the adjustable wrench handle on your left side, and pull the breaker bar/ratchet handle toward you which should also be pointing to the left. To tighten the yoke nut the procedure is the same except everything is on your right. It helps if you hold the jaws and reg in your free hand to help steady the pivot point.
I've used this on MK5's and 10's.
Seriously, if you aren't using a vise or box you should use a strap wrench. There would never be any concern about damaging the finish and they are dirt cheap.
