game said:There must be something wrong with wood?
There are only two things that have gone wrong with my Zone VI tripod in over 20 years of hard use.
It came with black plastic knobs for tightening the legs that I replaced with metal wing nuts. The legs would swell so much in the rain that I couldn't loosen them by hand, and they broke when I resorted to bashing them with rocks. I've since refinished the wooden legs as well so they don't absorb so much rain anymore.
The thick plywood support for the head of the tripod on top of the legs also got replaced. All those years of rain forest use, then six months tied to the deck of a sea kayak caused it to delaminate. I replaced it with a sturdy piece of sheet aluminum.
Those are the only things that have ever gone wrong with mine.

P.S. Make that three. The small screws that hold the spiked feet fell out, so I put in bigger ones...the wood in the spikes was starting to rot.
