more engines at www.indianarog.com Here is a pair of Jensen 51 replicas built by me...the one on the left about 3+ years ago, the one on the right was just completed April 2009. I'm 99.99% sure there is not another video out there of TWO such engines running side by side. Only 27 original Jensen 51's were built by Jensen using their Jensen 50 as the core...I built two more reasonable facsimilies with added functionality. Originals had one lamp and one motor...these two have five lamps and one motor. They were fun to build, but these two will be it, NO interest on my part to build another.

  • Well done Rodger, both are beautiful models. i noticed the big goveners on the 51's, are they just for show or do they work?

  • Yes, the governors DO work. As the engine speed increases it causes the governor to speed up as well since it is tethered by a spring belt...the governor's spring loaded arms/balls rise giving some resistance, As the governor arms rise they lift a lever riding in a groove and subsequently that lever gradually closes off a steam valve within the steam chest. By this method it self controls top speed to avoid exceeding designed in rpms...it works very well and is totally adjustable.

  • Heh heh, yours is bigger. Well the water tower is.

  • Yes Ranger, mine is bigger :)

    BUT, Mike's is more correct measurement wise
