I have already bought some old, and beyond repair machines on ebay and replaced the defective parts of some machines. In the long run, however, this is too expensive. Would be just nice to always have suitable plates in stock, which would then be cut to size and bent immediately are available for installation.

Hello,
very good that Jensen sells the fireboxes with the brick imitation as a spare part. This is actually not good at Wilesco. Especially the fire chambers are heavily stressed with frequent use. However, with prudent use of the machines, this should not be a problem. My problem with the brick immitation plate is that I need it for a pair of my 90+ year old Doll & Co. Machines. This then becomes difficult to impossible. I did locate a company in Cologne, Germany that could make the plates for me, but at what price. With my small purchase quantities unaffordable. :-\
Hello, I do not know your exact needs, but could it be possible to watch the used auctions such as ebay for a used perhaps larger model Wilesco/Jensen or other? The Tin embossing bricks are quite thin and not so hard to work with. Perhaps you could purchase a "parts" machine that is broken or missing major components at low cost and remove the "bricks" and cut down or form them to a new shape to suit your needs?
I have thought of doing this for a custom build....just a thought.

Congratulations Ben!!!
A lovely little engine, and unlike your initially intended purchase, i dare to promise that this one will actually run when fired.
Looking forward to see what choice you make, when it comes to firing this.
PS.
If it was me, i´d just fire it as is, and make fists with my toes while the paint crumbles.
It can always be repainted if so wished for...and a new firebox is listed for approx. 13 bucks on Jensen´s online parts list...just saying 8)
Thanks for the tip of Spare Jensen "bricks" boiler house available at low price Jan.
That is a Part that Wilesco will not sell you....it seems if you have damaged your Wilesco bricks, you have had "to much fun" and your "penalty" is you must buy a new engine to get more bricks ;D

Ben ....I delight in YOUR delight, sometimes those of us whom have been collecting for a bit forget the pure joy of a new engine , thanks for reminding me.😄👍
I hear you Bruce. I really do Love the hunt for good used engines and the construction (the way it use to be) of older engines, and hunting for bargains and rare birds.
However, this little engine definitely did not break the bank AND it's so refreshing Knowing that someone else did Not:
cross thread/overheat/dent/tamper/loose parts/dissassemble/run dry/wrong water type/wrong lube/no lube/drop kick/crease/Burn/stress/drill holes in my engine while dirty :o
Sure...I plan to do at least one of those things, but At least I can have some control over the outcome 8)
I have not fired it yet but can tell I want more Jensen's.

It feels so "weird" getting EVERYTHING an engine is supposed to come with New! ;D
I was going to ask what that little square of metal is for, but instructions are so short I read them...it is the sight Glass window Wrench!
It feels like a little Tank! ;D
I am not going to fire it till I figure out what I am going to do with the bricks paint issue.
Feels like Christmas in May! :D

Well, We have about 3 first's for me today!
1) this is my First Jensen
2) first time I ordered a Wilesco and received a Jensen
3) first "Brand New" Stationary Steam engine!....was going to say first brand new steamer of any type, but remembered I did get my traction engine new.
This seems to be a goodwill effort from ministeam as they are experiencing growing pains with there new website.
To be continued....

...The Burnac Vulcan, along with the Mamod SE2,
use a 'choke' as a throttle...
Same for the original Mamod TE1 traction engine, and that works really well too :)
-
I have a Jensen #35 and have wondered why there is no
exhaust choke. The Burnac Vulcan, along with the Mamod SE2,
use a 'choke' as a throttle. The throttle/choke on the
Burnac seems to have a better range than that on the SE2.
The exhaust port exits toward the boiler and the other
side was tapped for the thumbscrew. Screw in to slow
down and out to speed up. I added an end-of-post photo
and YouTube video demonstrating it. Maybe you can mod your
engine and add a choke. You just have cogitate on it a bit.
That's what I tell my wife I'm doing when daydreaming.

Good Luck,

My thoughts on restricting the exhaust on an osyilator type engine would be the pent up pressure might make it escape from between the cylinder assembly and the steam chest.
Doesn´t happen on Mamods.
Assume it merely is a matter of having a trunnion spring matching that of your safety valve.
True that 😊👍

It "looks" like Bruce fitted a rather fancy needle valve to get control...but we will wait for Bruce to tell us what Really happened :)
I had a question as well, did the boiler have a port for the pressure gauge, or did you "steal" a thread that was a mounting bolt for the Overtype unit Bruce?
You are exactly correct on both assumptions Ben , the pressure gauge replaced the hold down screw for the flywheel frame. I probably had 6-8 hrs in that custom valve , & not sure if I could build it today.
By far imho it's best regulated by controlling the heat source, a 200-300W immersion cartridge heater would do the job nicely.

Remember that one well Bruce, that sure was some cool mods you did there!
However, the steam control on it appears to be a relatively advanced build, compared to inserting a simple premade exhaust valve, which would demand no more than a bit of soldering?
-
Jan is correct , a Jensen #85 a much superior plant than the Wilesco #3 , a control valve can (& has) been done to an #85 as shown in the video , Nick now owns this plant.

Great Mods Bruce!
That "Nick" guy....he just "knows" where to go to get the "Good" stuff.
Thanks for sharing!

Would be perfect extending the exhaust beyond the valve, to collect all the condensate Ben :)

My head was not going in that direction, but now I see your photo and ideas, I like it! Thanks Jan.
In my trade we use a ton of air cylinders to move things, we put "flow controls" on the cyl to control speed and prevent violent slam at high pressure. The flow controls meter in one direction, you can meter incoming air OR exhaust air, we Always select meter exhaust air as the cyl will move Much smoother! The piston is seeing full power and we are just slowing it down by making it harder to exhaust. Metering the incoming air can give less smooth motion. A steam cyl is pretty much an air cyl made to take the heat of steam.
Also if I tap a line into the exhaust port, it might be nice to run it down to a tiny bucket or chuff pot to keep condensate from running down boiler.
Thanks for helping me get my head straightened out Jan. ;D

A fine deal you struck there in my opinion Ben.
The 85 is a WAY better engine than the D3!
No steamline, the steamchest is screwed directly onto the boiler.
But it is very easy to ad a control, as the single exhaustport exits opposite to the cylinder rear end.
Not much magic needed, to ad a valve there restricting exhaust.

I had placed an order for Wilesco D3 from ministeam, Only because I have this Crazy Modification Idea I want to try. Listing said they had (1) unit in stock, but it was not really there. They had zapped my card for $ and contacted me, they Could refund my $ but hoped I might take a Jensen 85 in the D3 place?
I was fairly ok with that trade, (only disappoint is I can not yet try my Crazy Mod) which leads to my question.
Is the Jensen 85 completely devoid of a steam line? Perhaps I just have not seen a photo from the correct angle to view it, but My suspicion is the steam chest is solder direct to boiler, or perhaps a gasket?
There reason I ask is I would like to add a steam control valve to the 85.
