I had searched this site for ideas about mounting a model 00899 rain gauge but was unable to find anything. The manual is not particularly help, either. I ended up asking a friend to see if he could come up with something and I wanted to share the outstanding result. He used galvanized pipe, threaded at the top, and fabricated a base roughly the same size as the base of the rain gauge. The base screws on to the pipe (for removal during cold weather) and the base of the rain gauge is attached to the metal base with two screws, for removal for battery replacement. The pipe was roughly 6' long, so we were able to drive it about 2' into the ground, making it very stable.
