Jensen #35 1/2, overtype, locomobile steam engine conversion
« on: October 10, 2022, 09:04:57 pm »
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.

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!!!

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.

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.

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!
