OK, installing the beadlocks.
First he sucked the tire flat with his HVAC vacuum pump to break the bead. Then he had to find a way to secure it. Fortunatly we have stud holes in the garage floor to secure the bender in place.
The rest was cake! (6+ hours worth of cake!) I'll let him explain the process, here are the pics      

After he did the first one, he sucked the tire down again with the vacuum pump so it would be lighter to put it back on the Mammoth.
