Amazing Restoration 8)
-
As all can imagine, I have followed the restoration of my old childhood Jensen Model 45 upright with intense interest, and I remain amazed at the capabilities of those active in the hobby, and the things that can be done with the proper tools, skills, know how and experience. The old 45, will soon be done to return to its spot on display in the cherry dining room lighted display case. It will not run every day, but it will run on special occasions as a testament to the skills of St Paul Steam, and all those who assisted including Jensen Manufacturing, and other participants who helped with encouragement, physical assistance, builders plate restoration, and the joy of watching the old "girl" come to life after a slumber of 60 years. My thanks to all. I understand that only some nickel plating remains, and then some finish photos. All around thanks to everyone. Fellow hobbyists with tools and experience are a tremendous source of help to we amateurs. The next generation of engines would make a great gift to some young steam enthusiast that would carry it all on. Thanks again to all! Bart1353
Your much to kind , it IS finished & the final video is above this post 😊👍

Good points all. Also your cylinder volume is greater than stock.

Yessir..... 600 w is serious overkill.
Not as bad as you might think for a 3" x 4" volume of water , 300 watts is a bit anemic , 600watts is more than adequate for this set-up (& I think it could handle it) but would probably crisp The paint in short order , Jensen boilers of this volume can handle this kind a wattage with no problem , but they are nickel plated (not painted) and the heat isn't supplied directly To the firebox as in this special application.

You've done a great job with this restoration. Very well done, Bruce...!!!
600 watt heater ought to make that thing sing.

Thanks Gil
The beast needs tamed with a voltage reducer , restraint is required 😉👍

The nickel plater finished the sight glass lugs, screws & protector plate Friday so I was able to finish off the Jensen #45 candlestick engine project.
here is the finished engine. I will be boxing it up & sending it back to the original owner since 1958 , to Iowa on Monday morning.
I mistakenly stated that it has a 300W heater, it has a 600W heater now.
Please.forgive the slight "un"trueness of the flywheel , despite carefully rotating it around the axle for the least wobble , this how it came from Jensen Mfg. In 1958.

Your very kind Bart1353 & your comments are heartwarming & much appreciated.
after running this for a few hours breaking it all back in to one harmonious unit I couldn't help but get more annoyed at the 'rattle fit" that is the factory fit of the axle in the center tube of the boiler , while I wouldn't call it a snug fit the 16k slop bothered me & I decided to make very thin brass shims to try & solve the problem , they did & here there are.

the shim with the thicker lip is on the flywheel side , the engine side had to be kept trim in order for the cylinder assembly to stay seated properly. they were both compressed in place for a nice tight fit.

Ok folks , I have had another weekend in the shop finishing this up , here are some more photo's
I had an old (age appropriate) cylinder assembly from a Jensen #35 that I used for this #45, it is a 1/2" bore vrs the original 7/16" bore & required much modification, I put in a longer connecting rod shaft (Andy @ Jensen helped me with that) I had to nip the piston down a bit & I made a custom crank head & pin for it.

I am still waiting for the Nickel platers to get done with the sight blocks & protector plate , but I have "borrowed" a sight glass set up from another engine temporarily & have put at least 2 hrs run time on this engine now , the paint is turning a little off color right at the heat line (like they all do) but otherwise is running very well & I am happy with it so far.
Again I have followed the amazing creative restoration work on the circa "Christmas 1958" Jensen Model 45. You should note that its return to steam represents a return to life after being cold for over 60 years. That in itself is a great accomplishment. When all the work is finished, this engine will reside in a place of prominence in my family and will be one small remnant of my generation. My thanks to Bruce for his great commitment and his great skills, and to the folks at Jensen for their technical assistance, and to all Forum members for offering their help and encouragement too. Looking forward to a future unveiling upon its eventual return and a grateful thanks, and some measure to cover what expenses can be squared. Bart1353

And of course, after you did all the hard work a 45 comes up for sale in Ohio...

It doesn't matter if another came up for sale , the History of this particular engine was the important thing , & that's why I restored it for him. 😊
I was meaning more for the cylinder assembly, but I think the FB guy is seeing $$$ and won’t give a price
Sorry Nick , realized that was what you were getting at , the one you listed is actually in much better original condition & would have saved me many hrs. Labor , but the provenance was important to keep as much of this intact as possible , plus I would have had a better example of a #45 with no cylinder assembly... Lol
I am kind of interested in what he's asking though ?

Just wondered if it had managed to fly under my radar on Ebay, all is good now that i know that wasn´t the case 8)
-
Is that one found on Ebay Nick?
Spotted it on one of the 8,397 facebook groups :D
I asked for a price, but he only gave me pictures. Said he’s never ran it, but may try to.

Fantastic work Bruce, looks brand spanking new mate!

Good to see that a #35 cylinder assembly (with a lot of modification) can be used if needed. That tag turned out great too. 👍
Thanks for your help with the tag Nick , couldn't have done it without you 😊👍

Absolute Magic! Bart1353

So much improvement, doesn't look like the same engine. Well done!
-
Jeez Bruce, you don’t mess around :o Fast work!
Do you have a cylinder assembly on the way?
possibly , I have located an original but it has cracks in the cylinder (as many of them do) but might possibly have something better in the works.
-
VERY nice job there Bruce, well done!!!

Freshly downloaded video of the progress...I need to find some mica for the heat shield between the ceramic heater & metal base under the boiler. I also need the cylinder assembly.

You’ve got some great skills Bruce, thanks for documenting this one. This would have probably been a parts/scrap engine to most, but being it has history and childhood memories it’s a good one to save.
Thanks Nick
That is the only reason I decided to look at it...and ultimately take on its restoration, its apparently more than just a beat up old Jensen #45 needing a lot of attention , its a cherished childhood memory that the owner intends to pass down to the next...and next generation , hopefully when I'm done , it Will perform as designed for those generations & look good doing it 😊👍
