After studying about designs of old engines I began to wonder, did the old ones really run? I decided the best way to find out was to build one. My first one, the Bischopp, turned out to be a real challenge.

Next I thought I would try something even older. I chose the James Robson Cogwheel engine built in North Shields, England in 1857, which was 14 years older than the Bischopp.

When he was 19 years old, Robson was experimenting with gas to heat an incubator. This experiment resulted in an explosion which almost killed him. He decided to try to harness that power. The result was the cogwheel engine.

James Robson was not an engineer and had even less engine technology available to him than Bischopp had. Robson's engine had all the components to utilize the fuel of the day to develop some form of continuous power.

My biggest problem was how it ran, not how to build it.
