I have a plastic waterer in my coop. I purchased a galvanized double wall fountain (that's what they are called) waterer for the run. I really like to clear up floor space, so I wanted to hang it by a chain and not set it up on cement blocks. I realized it did not have a narrow spot in the handle to keep it centered on a chain link (unlike the plastic waterer). Without that "spot", it would shift to one side or the other and spill. I took a chain link, (the kind that screws open and closed in this case) and got some JB Weld from the workbench. JB Weld is basically a 2 part epoxy with metal. I "welded" the link in place (perfect center of the handle). Now the fountain can be hung, and the attached chain stays centered. note: to keep the link in place while the epoxy is setting up, simply hang the fountain on the chain in the correct position. Of course if you have a "real" welder, you can always spot weld a link in the center. I can't understand why the handle on the fountain is made that way. The galvanized feeder (same brand) has an indentation in the handle to keep it centered.
