Bruce, I saw this baby first hand and your firebox construction is a thing of beauty.  Sure wish Jensen themselves could commercialize this engine, it would be perfect for many steam afficionados!

Wow Bruce, that is really something!

A hundred years from now some Jensen aficionado is going to be scratching his head for certain and for sure!!!
You could very well be right Daniel,  or maybe...just maybe someone might remember that a little one man shop in St.Paul In. Had a propensity to do one off conversions of the weird and strange. 😄

Not weird and strange at all Bruce, but a classically designed (in the German overtype style), highly functional and might I even say, actually elegant representation of a very desirable all-in-one steam plant.
Thank you Daniel 😊
I did study dozens of overtype steam engines on YouTube and came up with what you see above, I wanted very much to have the flywheel forward of the piston assembly but I really wasn't willing to do that much drilling & filling on such a pristine unit. The Jensen #35 seems to be one of my favored units to modify...generally inexpensive, powerful  & highly adaptable to what I'm trying to accomplish.I have build photos if anyone's interested in the process.

good idea and a very nice steam engine -
maybe Jensen will copy it...
Compliment, Arnold :D
I don't see that happening Arnold,  they haven't produced this model for over 50 yrs. Jensen mfg. Is basically a one man shop now with Andy's son helping out every now and then.

This is my lates project of converting a Jensen #35 into a German overtype style steam engine. this started life as a very little used in the box Jensen #35 now with a custom firebox (double walled internally, a custom cast iron yoke supporting the front of the boiler via (2) fillister 6/32nd nickel screws into two brass enclosed pockets soldered into the boiler. it now sports a 600+ Watt immersion style heater in the boiler & this all sits on a 1" thick x 5 1/4" x 9" oak plinth. has a custom ID badge. the safety valve is custom made to fit inside the chimney & is 7/8" tall with a 0 ring groove cut in near the top to create a leak proof chimney.
