Thanks everyone glad y'all like it. If you got a Jensen model 10 or Deluxe power plant you want to let go of, let me know. Complete or parts.

Wow, that’s quite the stash of Jensens. Would love to flip on my shop lights every day and see those looking back at me.

Talked him out of restoring it. Just doing a good cleaning, fixing and replacing missing parts. Trying to preserve what is there. It can only be original once. No matter how much you try you can't ever put it back.

This is so true! I don't see rust, so no reason for paint.

If you look at a fire truck pump that Nick posted about: a "tatty" original paint one sold for $1000, while a resto sold for $300.

Jack picked up his D valve engine so thought it would be neat to set them all together. Jack done a video and put on you tube. He mest up in a few of his description of the engines but in all done a very nice job on it.

I counted near abouts 14 #10's before my neck muscles gave out...lol, plus all the beauty's you have tucked elswhere's , quite a fantastic display Randy, I cant imagine Tom Sr. getting more than 3 completed a day, so you have a weeks worth of Jensen production there !


You have a point Bruce.... However that week is spread out over 50 years!

Well had alot going on lately but finally got to make missing parts. Now time to send new parts to get nickel plated.

Post by: txlabman on September 06, 2019, 10:15:21 am
I know about these holes in the firebox. The very first Jensens were built with open flame heating requiring the vent holes. At the first major toy show that Tom Sr. showed them, he received his first order for 50 engines contingent on them all being heated electrically. Rather than make new fireboxes, (remember, Tom Jensen Sr. wasted nothing), He simply added electric heating.

This engine appears in Jensen's earliest known advertising and the cut was used throughout the 1930's and into the 1940's even though all the engines sold were electrically heated.

Hope this helps,

Thanks for posting the adverts Gil.

I hope you enjoy the Dublin Show. Looking forward to seeing the video!
Gil

Here are two of the early ads and both have that ultra rare Big Power Plant
with the vented firebox and slide valve engine.
Notice even the artists cuts in the ads ads have the electric cord.

The cord is twisted cloth covered wire. By the way it is attached to heater I would say it's original. It is wrapped with cloth tape at connection very neatly done. Still very tight and heater works, so I'm not taking it off. Someone had added a more modern cord to this cord to make it longer. I took that cord off and put a new old style end on it.

Thanks for the reply Randy. And good news. Amazing that the heater still works.

Interesting to see Jensen used D slide valves on their early engines, first time i've seen one of these examples.

Yes it is Jack's engine. (Trying to talk he out of it). Don't think it ever had the asbestos lining in it. Talked him out of restoring it. Just doing a good cleaning, fixing and replacing missing parts. Trying to preserve what is there. It can only be original once. No matter how much you try you can't ever put it back.

I totally agree with you Randy.  It is only original once!  Please don't let him restore/ruin it.

When I visited Gil in January, I got to run a similar engine that Gil helped bring back to running condition:  You can see me running it at the 3 minute mark of the below video.  Running it was amazing.  What an engine!

Yes the rivets in bottom are peened over. When I had the heater out to repaire whistle bung you could see inside boiler good and tell they where peened down tight and then soldered.

Post by: St Paul Steam on September 03, 2019, 06:29:45 am
Love this piece, thank you for sharing it with us! That boiler sure is neat, and the seam is riveted quite crudely compared to the endcap rivets (understandable since Tom Sr. had a tool for those)

Neat that Gil's ad also shows the slanted gauge and drain cock, many times toy steam ads aren't an exact match, but these look more like actual pictures.

Wise choice to not over-restore this one...
" ad also shows the slanted gauge and drain cock" good eye Nick, it also looks as if the rivets on the bottom are actually peened over & not merely soldered in place.

The new end on cord. Don't know what it would have had originally,  but this is what was used in that time period.

Is this Jack Boyle’s engine or another one with the Chromalox heater?  Seeing 2 in less than 10 days would be less likely than winning the lottery. 🤠

I am curious about the cord. It doesn’t look like the cloth cords from my early Jensen Riveted Boiler engines. Do you think it is original.

Has the asbestos lining been disposed of?

I breath a sigh of relief knowing this rare beast is in the hands of a skilled restorer!  🙏🙏🙏

Title: Re: D Valve Jensen
Post by: Randy Tucker on September 02, 2019, 07:31:37 pm
Can't really answer why vent holes.  Only thing I can figure is maybe he was thinking of making it fire heated and changed to electric? It has the Chromalox heater in it. I know that's what he used in his very early stuff. It's been suggested that it may have been to vent heat out from under boiler away from board. There is no insulation in firebox so this maybe why.

Randy, that sure is a rare beast...I personally have never seen one before...good it landed in your hands to bring it back to life.

Why do you suppose the fire box has vent holes if the boiler is electrically fired?

Very interesting engine to be sure!!!

Have had the honor of having this in my shop. Only doing a good cleaning and making missing parts for it. Still got a few parts to make but it's getting closer to being done.  This is a very different engine from normal. The boiler was rolled from flat sheet brass and riveted, has D slide valve made like full size steam engines, has drain valve in boiler, throttle valve is in steam line block at steam chest, vent holes in firebox and firebox was made from galvanized sheet metal. Very neat engine. Hope to have it done soon. Still got the make lamp post and relief valve for it.
