Thanks for the kind words guys,

erebus, I will get you some better pictures of the clamps and how they are put together. There fairly simple 3" or 4" channel will work. They need pads on the back of the channel to keep them from wanting to roll to the side and they also help spread the load over a larger area. The T handles are 1" threaded rod with rod couplers welded to the channel. 1/2" threaded rod would be fine also. They work unbelievably well.
