I second the turntable suggestion. Triple black pin two beams to the molded-in
mounting lugs and you can make a perfect space to worm-gear the outer ring. As
an added bonus you get tons of mounting surface to put the rest of your big-
rig construction. You can even use a pair of turntables to make a joint that
can handle real stump-pulling torque. These are some of my favorite parts, and
almost a must for large projects. You can buy them at Pitsco, but they are not
cheap ($10 I think). Buy a few extra parts when you order, because it is easy
to start snapping things when you go big with strong cross-pin construction.
