I scored a similar type stand for $50 online....The shipping must have been that much, considering that the stand probably weighs 50-6- lbs.
Anyway, what I did was take the ends down to my local muffler shop, and asked them to put 2 bends, each 10 degrees, in the pieces, with about a foot between the bends. ~ He guy didn't want to take any money for doing it, but I gave him a generous tip.
It worked perfectly! The stand is high enough off the ground, and still has enough space for the hammock to hang between the ends.
