E. P. Lain is the engineer operating my engine on the Baker Fan. This is at the Stephenson County Antique Engine Club, Inc. at Freeport, Illinois in 1972.

I am sending you some snapshots and a few lines about a one-half scale model Case 65 that I built. This engine is popular with model builders. Each time I see one in the Iron-Men Album I marvel at the finished product, for I know how much time and effort each person put into it. This goes for whatever make the builder uses for his model.
If one wants something bad enough and long enough he makes a way to get it. I always wanted a steam engine. It occurred to me if I built one myself it would not cost very much. The Case 65 is a well proportioned engine. It looked like it would be easy to build. It would be a one-half scale model.
The patterns were made from blueprints. To get the right contours and shapes to the castings, snapshots were taken at close range of everything on a full size Case 65. All parts were photographed several times from every angle possible. By using the dimensions from the blueprints and the pictures it was possible to form the patterns.
Making patterns and core boxes was new to me. If one part could not be made there would be no use going on. The cylinder with its parts would be the most difficult, as the steam ports had to be cored accurately. The cylinder block came from the foundry perfect for machining. The pattern for the engine frame was a bit of a problem, but, it too came from the foundry perfect. From then on the remaining patterns were fairly simple, although it did take a long time to make the pattern for the flywheel. The cannon bearings, the wheel hubs, both front and rear, were cast from patterns. Every casting on the engine is an exact duplicate of the full size engine.
Now about the boiler - I learned that a boiler has to be made by a licensed boiler maker in order to be state approved. About this time Iron-Men Album came out with a cover picture of Mr. A. C. Otto of Sandwich, Illinois and his one-half scale model Case 65. This was in 1955.
I went to see Mr. Otto but did not get the boiler at this time because I became involved with another project. Not until 1967 did I get Mr. Otto's boiler. It is a welded boiler built to exact scale and licensed for 150 pounds steam pressure.
Mr. Otto has available all the castings for anyone who wants to make this engine. I did not know this before I started. I had made and machined the parts of the engine proper, but did not have the gears and clutch assembly, etc. Mr. Otto had these blank castings so I got them. These are the only parts for which I did not make patterns. The gears are designed to allow the engine to move at about five miles per hour.
The castings too big for my lathe were done at the Bauder Machine Shop, Sterling, Illinois. Clair Bauder, the owner, made available to me any machine I needed so long as it was idle. The men in the shop bent over backwards to help me. To Mr. Bauder and all the men I am grateful. In this way all parts were machined that could not be done with my equipment. Incidentally, the cutting of the gear teeth was quite a project. In cutting the last groove it was a worry whether that last tooth would be too thick or too thin.
All brackets necessary to fasten the various parts to the boiler were welded to the boiler by Mr. Otto, such as the engine frame bracket and the wing sheet brackets. By this time all parts were ready for assembly. The engine frame was the first part to be fastened to the engine frame bracket in front and the wing sheet in the rear. The right bearing assembly was fastened to the opposite wing sheet. Both were braced to the boiler the same as the big engine. The quandrant shelf was fastened to the boiler and wing sheets. From here on all parts were mounted in relation to the engine frame, and the use of the blueprints. To pour the babbitt for the crankshaft, two plates were fastened to the outside of each bearing. By doing this the crankshaft was held in the correct position. By tilting the boiler from one side then to the other it was easy to pour the babbitt. All the parts of the engine were assembled. It was far enough along to run. Air was used to try it. It ran good in either direction. The 'D' value and all parts relating to its setting were done the same as the full size engine.
The governor is a 1' Judson such as used on some Case engines.
Both cannon bearings were fastened in place on the rear of the boiler suspended on springs, the same as the full size engine. The rear wheels were made and the gears attached. Bronze bushings were used for bearings in the front wheels. Oilite bushings were used in the differential. The free side of the differential gear is bolted to the pinion gear over a bronze bushing. Every part has a zerk fitting for greasing.
A good part of the work was done at Mr. S. W. Naylor's building in Sterling, Illinois. Mr. Naylor manufactures Swenco corn dryers. My lathe, drill press, etc., were in his building. Thanks to Mr. Naylor, this is where I assembled the entire engine.
All pipe fittings are high-pressure. Two Penberthy injectors were used. The whistle is homemade. It is a chime whistle.
It was a big project. It turned out just like the full size Case 65. The power it develops is amazing. A steam engine is the only inaminate object when fired up just sits there hissing and throbbing to get going. Steam has a fascination all its own.
It was not to cost much. This was wrong. By the time I was finished it had cost quite a few dollars. Anyway it was fun.
I don't know how long you have been publishing the Iron-Men Album. I have all the issues from the Nov.-Dec. 1954 issue to the present. It gives pleasure, no end, to read and reread them.
Thank you for a fine magazine.
