Here are some pictures of a couple of scratch model engines that I built.

I've completed the 7 HP Waterloo Boy featured on the cover of the March, 1992 GEM. I got interested in building a Waterloo Boy model. This model is approximately scale, 12-14 HP, 1912-1916 complete with seat, battery box, horse pole, neck spoke, and double tree. The battery box is out of proportion but it holds the battery and coil.

It has a two inch bore and three inch stroke. The flywheels are ten inches in diameter. It weighs over 60 pounds, and it runs nicely below 400 RPM.

The Tom Thumb is approximately scale with 1 x 1 inch bore and stroke. It has 7 inch flywheels and runs at 600 RPM. It weighs about 30 pounds.
