Hi all, this is my first post and I hope that it is appreciated here. I have attached a zip file containing drawings of the elbow engine described in an article in the July 1965 issue of Popular Mechanics (http://www.john-tom.com/MyPlans/Steam Engines/ElbowEngine.pdf). I made these drawings from a solid model for a class on GD&T, and made some modifications to the dimensions to simplify them from the original fractional dimensions.
