We are just looking for 3 vortex rings, we have a bridge with rails, a motor, and someone that can build the rack for the rings. So we are looking for a set of 3 metal rings, does anyone know of anyone or any company that sells just the rings??

I have seen them made out of wood. Check out this link.

Find a local metal fab shop or industrial mechanical (heating/cooling/plumbing) contractor. Have them roll some tube for you. They can do it at just about any radius you want. It should not cost much.

Check ebay for a greenhouse tubing bender. These bend galvanized fence posts into 10-foot diameters. They bend electrical conduit or thinner metals with no effort at all. I got mine for less than $75 shipped. It worked great.

we went to a utility company and pickup some old cable spools and cut out the center of them. email me at firstname.lastname@example.org with questions
