My little experiment with trying to get a better flame from an alcohol burner. It was primary school and i kind of lost some eyebrows then🤣.

Jensen's steam engines aren't too dissimilar to Wilesco's, made in the USA since 1932. Little less polish on the finish perhaps, but engineering wise they're quite well made. Have a #75, the biggest in their "Hobby Line", has a working Stephenson valve gear along with a regulator, whistle, safety valve etc. Only complaint I have is the paint on the boiler house burnt and flaked off, and the steam exhaust isn't routed to the chimney like on a Wilesco, but it's been a good little engine, was a bit cheaper than its Wilesco equivalent.

Backing out the 3-4 through bolts and taking the top plate off would be ideal. Being safety vented at 15psi (appx 1bar) and loss on every other stroke I wouldn’t have worried about the pop off valve as a paintball gun, cylinder engine and other aluminum bored equipment like nail guns operate at 90-120psi. I’m sure there’s an engineering formula to prove the point of boiler volume at any level of fill couldn’t reach critical with flow volume at minimum, but I’m just going to leave it at sensible working pressure of like equipment being 8-10 times the pressure at much higher flow volumes work.

Any reasonably thinking (read non-twit) would view this engine as something to engineer. I and my friends have had this trait since about the age of six. We would cap the wick openings and go to one TRIMMED wick. We'd never light a dry wick. We'd try different fuels. We'd mount that stack deeper or change it. We'd design a safety valve. We'd improve the throttle. We'd feed the excess water to a feed tank with a valve. The UK has nanny stated the people so much they have lost the ability to dream, dare and innovate.

[@briannemec9214]

Since you added the much needed safety valve, you could bypass their safety system. If you would plug the the hole to atmosphere on the control valve block you would use less steam and have possibly have better speed control. This will use less water and help insure you do not run out of water before fuel. Make a project: put the lower device on wood or longer screws so the steam line is level. Make the steam line shorter and solder in a tee. with the one tee leg aimed down solder on a drain valve. A good review and the possibility of saving an injury. I was a senior engineer at a stream plant, people do no realize the danger in a pressurized vessel.

Not once did I see the valve actually vent steam before the steam engine vented steam. It indicates that the safety valve was not tuned correctly and with that being the case, it's better off having the tapped screw in than having the valve at all.

[@Reddotzebra]

That part about aluminium losing its corrosion resistant properties as you heat it up is also why metal plants love to show that work safety video of what happens if you expose hot aluminium to water... Basically, its "corrosion resistance" comes from it being so reactive that it almost instantly corrodes a protective layer of aluminium oxide for itself when exposed to oxygen. If you continually remove this layer or keep it from growing one however... It reacts really, REALLY quickly, with an earth-shattering "kaboom".

[@BrooksMoses]

Wow. That definitely seems "designed" rather than "engineered", and it's a showpiece of what one can do with laser-cut metal and a nice catalog of generic parts. There are some fascinating details like the fact that the screw holes in the block of metal visible on top of the boiler at 5:34 have slots to the perimeter, which I think are there to make it possible to cut them with a waterjet while cutting the outside. It is almost as completely removed from traditional machining as it is from any engineering calculations or judgement. I would be entirely surprised if the throttle blowby that Lawrie talks about is intended as a safety mechanism; that seems far more thought than was put into any of the rest of it. My guess is that, instead, the "made from off-the-shelf generic bits" throttle that they cobbled together is simply leaky. Also, it seems to me that this is less likely to explode than to have the bottom sheet on the boiler flex enough to leak around the perimeter and blow out its entire contents in a shrieking banshee blast of flash-boiled steam. This is not clearly an improvement.

The similar, but slightly different "bronze tone" is their fake copper look, and it's just as egregious. Not to mention it's gushing out wet steam and... that is NOT a safety mechanism by any means, that is a time delay on your improvised shrapnel generator if you run that thing dry by accident. The cherry on the whipped cream on the whole poo fudge sundae being that it's bloody incontinent, which means that not only are all the screw threads _cast_ instead of cut, they're cast _badly_ ... a brilliant piece of kit, but only if you're a fool, a madman, or a hitman whose target takes after Rube Goldberg just a little _too_ well.

You don't have to bend the pipe. Set the furnace on a block to raise it to the level of the reactor if the pipe is intended to be straight. Otherwise gravity should allow condensation to form within and dribble out one end under the influence of gravity. Also bending metal pipe can constrict it's volume at the bend... as exemplified by exactly what we saw happen.

So, with flames running up the side of the boiler, I guess the entire boiler barrel is now technically the crownsheet? 😬 I believe the Mamod safety valve opens at around 20psi, but a safety valve won't do you any good if the boiler itself isn't good for 20psi. I think you've got yourself a decent compressed air engine, and a bit of aluminum scrap.

[@lmm]

The engine isn't even decent as its letting half the air / steam go to atmosphere workout doing any work! I don't want to try and work out where a crown might be on this. Mamods are 10 or 15 I think. This is 20 The instructions say the engine runs at 15 so I figured a fair guess.

[@KlodFather]

If you want to test the pressure vessel, then pressurize it with air using a regulator and check where it goes boom at room temp and getting it really hot with a heat gun. That would work effectively but is one time destructive testing. If I have bolts in my neck and frankenstein stitches in my head, then you know why LOL

[@scottwillis5434]

A better way to pressure test a boiler is hydrotesting: fill it with water (or other non-compressible, non-toxic, non-flammable fluid) and apply pressure to that. If it lets go, as soon as it does the pressure goes away and the pieces of boiler stop accelerating -- vs. the continued push and explosion you get with steam or compressed gases.

[@buggsy5]

@@scottwillis5434 Not only a better way, but the proper way. Really high pressure tanks, like scuba tanks, are hydrostatically tested. If I recall correctly, to somewhere over 3000 psi.

[@nealc.6927]

1) It could be set up/mounted on a step, so that the engine steam intake is level with the boiler output, reducing the risk of priming. 2) The Burner could have the outer wick-holes blanked off, thus relying on the single centre wick. Slower to heat up but much safer. Also, a more densely woven wick would help. 3) A good model engineer could install a sight-glass on the side of the boiler for water level. 4) The slide valve could probably be adjusted or remade to fully cover the port. 5) A cheese-head screw, suitably fettled, could replace the Regulator bolt, thus taking out that backlash. 6) The steam-port piston could probably be re-engineered a la Mamod style. Thread the chimney hole for a more permanent, stable solution. Overall, despite the dodgy, it has the capability of being a good model. But NOT at that price.

The Pressure Equipment Directive (PED) is restricted to pressure vessels with a capacity over something like 1 litre. If it is smaller the PED does not apply and so it is possible to claim it does not apply to something small like this boiler. I don't know if the boiler regulations would apply to something as small as this but there are standards for miniature steam locomotive boilers so they may be applicable. I think the starting pressure of 15 bar (about 220psi) is confusing atmospheric pressure which is about 1 bar with 15psi which is also about atmospheric pressure.

Hi, thanks for your demo. I agree it looks good, but it stops there. I have always wondered why all or most steam engines send the steam down to the cylinders?

If someone could apply my suggestion, they could be on to a winner. Thanks again. 🇬🇧👍

[@cHAOs9]

I think the wicks are way too long and therefore the fire is way to big. It's made of aluminum (which i know you're not used to) so the heat transfer should be fantastic. Just a little flame underneath should be more than adequate. That may fix a lot of the other issues you are having.

[@sabik6979]

Exactly. The wicks are supposed to be trimmed down a bit. It's the same thing I have to do when I buy new candles. The high flames was causing it to get way hotter than it needed to be.

[@fukkitful]

Yeah, I was surprised it had some many wicks when just one would have been enough to heat something so small. It would just take a little longer to build up pressure but that would also make it safer.

[@ehsnils]

At least for pipe bending - get a brake pipe bending tool. But that's probably the smallest issue. I'd prefer to use a brake hose instead of a rigid pipe. I'd prefer to have the pressure gauge on the boiler. And in addition to the safety valve also have a blasting tin that goes into a hose that should go into a water filled bucket to take care of dangerous steam release. So the main issue is the boiler as I see it. So just run the engine on compressed air and it would be a lot nicer and less dangerous unless you overrev it or do some other stupid things.

[@lmm]

Compressed air would be the safer way to run it. Though it's still not a good engine

@@lmm I agree that it's not a good engine, but it's reminding quite a bit of the earliest steam engines made and those weren't good either.

[@ajayray4408]

I can see someone kinking the tube, either in initial assembly or when setting it up later, and then be wondering why nothing seems to be happening when it explodes. James Watt, like Thomas Newcomen before him, did indeed build atmospheric-pressure engines which depended on condensing the steam to produce a pressure differential for the power stroke (and he started down the road to his separate-condenser design when he was tasked with repairing a model of a Newcomen engine.) Watt was opposed to high-pressure engines on account of the danger, but you can't make an efficient and high-specific-power steam engine without going that route.

Commonsense. The steam is regulated by a needle valve. With a little knowledge, one knows the flywheel position is important BEFORE starting. As for the different heights, a piece of timber to raise it. I’ll give you the aluminium as an issue. It should be a steel or brass boiler. Maybe it ‘keeps running’ to use the steam and prevent an explosion. Add in the aforementioned pressure valve (a which again mine came with one) it is fine. As for ‘stopping’ the engine, maybe remove the fire? No fire, no heat, no steam, solved! Safety is important, but everything has danger. Mitigating the risks, is the key.

To improve this motor start with the mounting board. Put blocks under the motor so the boiler and engine are in line. Use a short straight version of the steam pipe. Next, tap the exhaust port, get a piece of steel tubing, and put threads on the end of the pipe so you can thread it into the block. As to the boiler maybe it is plated with nickel or some other metal to make it more corrosion resistant. It is also possible that it was anodized. With the added pressure valve it might be an ok little motor.

[@blindsniper35]

I have absolutely no experience with steam engines of any sort or boilers. But I do have experience with many different forms of HPA or nitrogen. This honestly sketches me out quite a bit. I've seen pressure vessel failures. I really really don't want to be in the same vicinity as them when they fail. I was quite close to a failed regulator. If I was a few feet in the other direction I probably would have died. It required tools to get it out of the tree. The pressure vessel rupture I witnessed I was quite far away from and I honestly was worried about shrapnel. There is absolutely no way you can convince me to go near any sort of pressure vessel without any safety mechanisms. This is honestly quite alarming but not surprising at all. Considering all of the rather dangerous stuff I've ordered off the internet. This just is on the very high end of the danger scale. Also I would recommend a CO2 fire extinguisher if you don't have one. Even a very small one would be fine. CO2 is far less likely to have any of the itching compounds and doesn't really make a mess. So people are far more willing to use it before a situation gets two out of control. I would also probably have a dry powder extinguisher in case the fuel fire gets a bit out of hand. If you're going to be screwing around with things like that it's better to have all your safety bases covered.

If you buy a product, assume its built to be safe, and blow your hand off.....thats on you. At worst theyll just close that account and move the listings over to another one. Think like a broker that doesnt give a shit about anything except making a sale. Thats what 90% of these seller accounts are. And no, they dont care. There is literally no punishment they have to worry about. Hell, Amazon has no simple method at all for users to flag false listings and dangerous products. Why? because they know these brokers will just have their bots go and flag competitors, like how they give all their other seller accounts positive feedback to boost their listings. No oversight means this capitalist practice of screw the customer runs rampant. Funny how a communist country is capitalizing harder than the capitalists...almost like that subtle narrative that creeps around The Mans™ big bad broadcasting companies transmissions isnt being entirely truthful...possibly even priming people to remain divided so they cant come together as a cohesive group against their interests (ie, investments).....Nah!

Good burners tend to either have a non-flammable wick, or one that can be retracted to control or extinguish the flame. I do agree that running less wick would likely result in a more manageable flame, too. The excess flame going up the sides isn't just dangerous, but is probably a large part of the "steam generator reactor's" inefficiency; you want invisible hot air going up the sides, not a visible flame. I would seriously consider running just a single wick in the centre, and stopping up all six of the outer holes in the burner. And lagging the steam pipe to reduce condensation. And reducing the slop in the regulator mechanism, somehow. And for me personally, I'll stick to running my steam engines inside a computer…

That's an astounding number of issues for a single product. It makes me wonder what the US Consumer Product Safety Commission, the Office for Product Safety & Standards, or our respective customs agencies could do about these unsafe items purchased by the unsuspecting public. It's certainly made difficult by the lack of a local company responsible for importation, distribution, and of course liability.

From my experience from ordering sketchy things off the internet. You've probably got about a 95% chance of not having a problem receiving it. They might do something about it if you file a complaint, but until that happens they probably won't do anything. Unless you fill out all the proper paperwork then there's a lower chance you'll get the item. Which is quite frustrating because when you do things the right way you're far more likely to get your stuff taken away even if they do comply with all regulations. Although I've never tried to order a steam engine before so no idea on that aspect. But considering I received an uncertified HPA tank which I refuse to use and decommissioned. I would say the chances are quite low that they'll catch it. That probably scares me more than the steam engine. At least the boiler not a 5,000 psi bomb.

It's sold as a toy, I doubt customs even give it a second look!

[@Redharp]

Nice pipe bomb, making boiler that is suppose to be under pressure and exposed to open flame out of aluminum is kinda bold move too.

[@IvanLeskov]

As a boiler technician (BT) I want this. Long may the boiler run. Hail USCG (WHEC-37) Taney.

[@lmm]

It failed shortly after making this video, so I wouldn't recommend it

[@keithgutshall9559]

I would take it to the steam workshop and have them look at it and test it that boiler looks kinda iffy to me .Keith Appleton on you tube is the person that would tell you about them

[@lmm]

I don't know if it would be worth their time!

[@mhagnew]

All they're going to do is look at it and say "no".

That is the only worry I have with some of these Chinese manufactured model steam and internal combustion engines. Sadly loads of the Chinese manufacturers do cheap and bypass the safety standards. And judging by many other models (including some model railway ones) produced in China of recent the build quality isn't great either.

[@lmm]

It's not stunning for sure

[@chanjoinaua5273]

If you are that worried, do wear safety goggles. And dont get so close to the open flame with your long hair!

[@goosenotmaverick1156]

I was worried for his facial hair for a second. 😂 Having burned my own beard more often than I would normally cut it back, I know too well how easily it can happen lol

Bending a small ID metal tube is fairly easy to do without kinking if you fill it with fine sand first. The typical method employs a long soft spring however these are usually unavailable. Sand works fine.

The importance of a safety valve was made to me during a science experiment where I tried to recreate the Aeolipile using a flask with two right angle exit pipes on the sides. It spun around as I heated the flask with steam coming out the exit pipes but the pressure was still building in the device until it exploded! Luckily no injuries but It wasn't worth the paperwork afterwards!

[@robertbalazslorincz8218]

...maybe don't film yourself doing something illegal?

[@lmm]

I didn't.

[@OEF_Vet_0331]

Seriously? 😂😂😂😂😂😂😂😂

[@JamesMorgan08]

@lmm I think it’s more a comment on clickbait titles
