Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

Here is the 3rd video of the Jensen 20-S.

I changed the generator for one of my prototype #15 ball bearing generators.

The original #15BL generators were designed and tested by our own SteamerJ.
There were several prototypes built by John before he produced the 15BL for Jensen with the extended shaft and extra stepped pulley.
I have several of these prototypes that John was kind enough to let into the Office of Steam a number of years back.

Enjoy,

Gil
