The dynamo and engine were from castings.

Thanks guys!

Thanks Doug.

Great display, Doug...!!!

You did a great job and your #25 boiler powered PM Research steam plant is just superb.

A great build for sure.

Congratulations.

How long did the build take?

Did you start from castings or machined kits?

That's a perfect matchup for a hybrid. Not too big and not too small, just right.

And now the final display item on the table.  It's not quite done yet, but it's close enough...

[attachimg=1]

Finished building a PM Research number 3 steam engine awhile back and while it runs great on air, what fun is that?  Steam engines should eventually run on steam.

[attachimg=2]

This is my PM Research/Jensen hybrid, or the PM 3G.  It's using a Jensen 2.5" electric fired boiler which powers a PM Research Number 3 engine.  A PM Research dynamo provides a load.  All the plumbing is PM Research, with the pipe and fittings (except for the valve) machined and threaded in my shop.  The engine and dynamo were also my work from the casting kits.

[attachimg=3]

The boiler came from my very first Jensen, a used 25 I bought years ago.  Since I have two other 25's, this one wasn't seeing much use anymore so I pinched the boiler for this project.  The PM dynamo was built awhile ago and being used as a standalone accesory and that also was grabbed.  I probably will build another dynamo later.  The light post was bought as a Jensen spare part.

When I mentioned doing this project last year, I was told the boiler would provide plenty of steam for this engine and they were 100% correct, when not running the dynamo you need to turn down the heat with a triac or variac or the safety valve will blow quickly.  The PM dynamo is a pretty good load for this size of engine, but it seems to be working well and actually better than I thought as a Jensen 25 has it's hands full with the same load.

Thanks guys!

I cheat a bit with the Wilesco drill press as awhile ago I noticed that not crossing the drive belts helps a good deal when running that hog.  Downside is that the drill is now running backwards.  ::)

Tomorrow I'll take the sheet off the final display on the table.

Hi Doug , those Terot  sterling's are an absolute "best bay" and have an amazing amount of power usually unseen in Evan a much larger engine , its doing yomans work running that workshop...I know that Wilesco  pillar drill press takes an inordinate amount of power.
Now for the Jensen #25g real nice work there as well , the bearing installation in the #15 genny is such an improvement on that steam accessory , well done Sir.

The Tarot is making that workshop work with ease.

Nice work on that Jensen .... it certainly looks like the pressure gauge needle isn't even budging while you have it running flat out .... can't ask for better than that!

The next item on the table is a late model Jensen 25G.  It's by far the newest Jensen in my collection.  I got it on a trade, but wasn't that thrilled with it at first as it leaked a lot of steam and had trouble keeping the generator bulb lit brightly without running down.

So I punched some new Teflon gaskets and worked on the throttle a bit to stop the leaks, but why stop there?  At the engine, I installed ball bearings at the crankshaft and real balls for the faux governor.  The generator got the same ball bearing treatment and two triple pulleys.  Somehow I managed to restrain myself and not paint the firebox (for now).

It runs much better now and it's one of my favorites.

In the video we start running slow but soon go balls out and get the genny lighting the bulb nicely.  Now the 25 has no problem holding speed.

I love the Tarot Engine.

I just posted a video to my table of it running some of my favorite Steam Toys. 🤠

Great minds think alike.

First off in the display is the new darling of the Chinese Sterling engines, the Tarot purchased from Banggood. 

Here it's pretty much straight from the box with just a bit of work done on the alcohol burner to get the cap off easily and the addition of a brass pulley.  The pulley is being used to drive my Wilesco 100 workshop and the engine is running all those pieces quite merrily.
