I read with considerable interest the article "Change River Levels with a Dam Site" in the December 2006 Model Railroader magazine (pp. 58-61). The article describes modeling a dam with Tainter gates on the spillway.
But unless I'm looking at Bob Boelter's model photos incorrectly, he has the curved face of the Tainter gates facing the wrong way. The trunnion bearings of the gate are on the low water side of the dam (which is correct), but face of the gate should be circular with the center located where the trunnions are. Bob's model is such that the face curves the opposite way.
