We used iron inside PVC, I believe. Works pretty well, but if it gets hit with a ball the whole thing makes a pretty sweet approximation of a sine wave...

Re: Building Practice Field

We recycled a bunch of steel pipe and Kee Klamp fittings from old practice fields to build our Overpass. FIRST used to love the stuff for field structures, so we've got several years' worth of it lying around in our building.

Re: Building Practice Field

a little update on PVC...
we used 1" PVC, and it isn't very strong...
it can barley keep up its own weight, the iron inside sounds good, but we don't have the money. Instead we're going to try putting some sort of rope/cord through the PVC to make it stronger, making it have a high tension to strengthen the PVC
