I built 2 but have not used them yet. I got a large compression fitting(2"), cut it in 2 and epoxied it to a piece of plexi. The fittings were from the plumbing section of home depot, easy to find right next to the tubing. I did have to spin the nut part on the lathe to make a groove for the 2" coupler mounted on top to keep the diameter the same throughout and then epoxied to the nut also. I wanted to try end make it easy to change membrane materials if needed and eliminate leaks.
