We have some that were made from PVC (the thick stuff, I think it's 3" diameter). One of the DH's made wood bases for them, but I've also seen one guild use plastic buckets, insert a PVC pole, fill the bucket with ziplock bags that were filled with rocks or gravel to give it weight and stability. Attached is a picture of theirs. For ours, we use a 1x1 at the top (eye hooks on each end of the 1x1, bolt at the top of the pole) so we can chain them together, giving more stability. We have agreed with another local guild that we will share racks in the future, so that means neither guild will have to have so many. The big problem is storing them from year to year. The bigger guilds rent theirs.
