As I mentioned in the building forum ( http://www.mylargescale.com/Community/Forums/tabid/56/forumid/7/postid/63236/view/topic/Default.aspx ) I planned on building a gas well to put along the back edge (about 3" wide ledge) so that it would block the fact that the world simply, well, ends. Then I thought a bit more, and decided to make a small oil well instead. I originally envisioned something along the lines of a 4HP Myrick Eclipse with attached pumpjack, but I didn't have the proper sized dowel for the cylinder....Soooo, then I made do with what size I had (3/4") , and found a couple spare cast iron toy wheels and ended up with something about the size of a 10HP. Rather large for this type of installation, but Star made vertical engines this size for in well drillers, so it will do. I'm still trying to decide whether to make a shanty for over it. If I had to do over I'd make the engine a little shorter. The beam is kind of cozy with the top of the hot tube on the engine. The valves are just brads... I was too lazy to model the springs. And the cooling barrel should be higher for a thermosiphon, or it should have a small centrifugal pump on the bottom pipe..... But that is getting kind of picky for a background item.
How it looked about 3 hours ago. One nice thing about being indoors is you can use basswood without worrying about it warping.
You're probably aware of this, but at an engine show (I used to show those) I saw a coolant tank that had a brass mesh top. It was shaped like an inverted funnel. The water came out of the engine thru a pipe and tended to run down the mesh screen, gaining air-cooling, then was caught at a rim at the foot of the funnel and sent into the tank, below. I never did get around to building one for myself.
