Well done Bruce!

I have one of these that I got from Brent a couple years ago.

It is one of my favorites. And yours is nicer than mine. :)

You did a first class job on this restoration.

Beautiful job and quite the runner!

If you boiled-down the essence of all the great engines in Jensen's 80+ year history and combined them, this is what you would get.  It has everything!  A riveted boiler with a tube sight glass in a plain, black firebox.  Dark blue painted cast iron bases for both engine and generator. A very well running #20 that effortlessly powers the generator with a spare pulley to power more.  Everything sitting on a rustic-looking board with brass tag.

The improvements are subtle and tasteful: a brass plug that actually holds the chimney and a nice upgrade from the Hayco strain relief.

Super job!
Thank you krypto31337
You have very eloquently put into words all my thoughts about this plant.  Reading what you wrote was music to my ears , exactly what I was striving to achieve.  Thank you 😊👍

Thanks Nick , the ol' 85 brings back fond memories , I doubt I could replicate that throttle valve again , I had a tremendous amount of time in that little guy , I'm glad you have it 😊
I will video the #20g on steam by Thursday.

I timed it & it runs approx 29 RPM's in the clockwise rotation & 33 RPM's in the counter clock wise rotation which tells me it runs better counter clockwise (slightly) using the exact same air pressure.

This is my foray back into Jensen's after working on many Wilesco's over this past year...feels good to be back.

What a Beauty!! 😍 😍

Wanna sell it before the weekend’s over? 😂
Nah... I'm really enjoying this one. I just put over 14 hrs in the restoration and Its puttering away next to my chair at this very moment.

Haha  :D  I don’t blame you there, just had to tease you about it… and to be honest, I wouldn’t want to see the price tag that this one deserves  ;)

Very nice work, both when it comes to restoration as well as modifications.

Great job (as always) Bruce! :)
Thanks again for your help Jan , the chimney was surprisingly easy to make  & I was pleased with the smokestack support as well , I wanted to make another one after learning how to knock this one out 😊

Turned out really nice Bruce - almost would hate to get fingerprints on that beautiful boiler!
Lol...you don't know how many times I rubbed down that shiny boiler every time I went to film it Larry , Tis a fingerprint magnet 😄

Hello fellow steamers
I picked this up 2 days ago in need of much work , I did a full "nuclear" restoration on her. it was missing the smokestack support, chimney, heater, pwr cord, rev spring, both springs in the SV & whistle were broken as well. I totally stripped all the hardware of the cast iron bases & bead blasted them & reshot them with the period correct Jensen dark blue I added two functioning oil cups on the engine & generator (which is now also a transmission) I fabricated a new smoke stack support (thanks Jan & Howard for your help) also a  smokestack of the correct size & configuration. it got a new heater & 3/16 AWG grounded cord. the 3" Riveted boiler is a Jed P vintage heavy duty unit. it runs very well at just over 1psi in either direction.

as picked up Friday evening

I worked all weekend on it , the restoration.
