S.P.S. Jensen #85
« on: September 27, 2019, 07:06:16 pm »
Took this one off the shelf to play with tonight and realized that I've never posted any pictures of it on the forum. Had it for awhile now, but Thank You again Bruce!!  ;D ;D

From Bruce's video to explain what he has done to it: Did some mods on this Jensen #85, they include a custom throttle valve, custom made pressure gauge mount, roller ball bearings on both axle towers with brass lugs soldered in to hold the bearings, I  made brass washers to ride against the bearing races as to have "0" lateral flywheel wobble, the engine is not broke in yet but will run on just over 2 PSI. firebox has been redone with VHT copper paint

A lot of stuff packed into a small engine,  I never made notes when a made that throttle valve & may not be able to duplicate again. Good to see the mini "Ram" again,  btw this is the engine  that powered 4 Jensen #15 generators. I'm glad you have it Nick 😉

Very fun watching the only throttled #85 in existence going through her paces, very slow tick over for an oscillator, it powers the Empire Swings nicely & with good control. thanks for posting Nick, you made my morning .

That is a very cool modification that Bruce has done incorporating the throttle valve into the block.
I think that is the slowest running Jensen #85 i have ever seen!  :o
