I totally agree!

If your new fittings can handle the temperature of steam (or if you're not opposed to upgrading them to handle it), there are examples of fireless locomotives in industrial use - some actually still used today, mostly in places where even the potential for sparking from an electric or gasoline engine would be hazardous. The principle is to fire a static boiler and pump the steam into a tank which is mounted to the locomotive. The locomotive then releases the steam pressure through the engine to perform work. Yes, the steam pressure on the locomotive will go down slightly over time even if it's is sitting idle due to the temperature loss, but this is actually a lot slower than you might think, and if you're close to where the static boiler is, it's easy to top it off again as needed. Some of your early experiments at making a boiler looked like they had promise, but I think adding the complication of making it in a unit small and portable to put on a locomotive might have been causing more of a hurdle. A static boiler wouldn't have that complication; you could make it big in order to more easily get a tank that can handle the pressure, which would probably be easier to obtain with scrap materials.

Steam pressure is a function of heat. It's not like compressed air in that you can pressurize it in a tank, then tote it to where you need it for use. Steam maintains pressure only as long as it stays hot. Hence why you never saw "steam tanks" back in the day. Second, dry steam for running engines is a totally different monster from what people imagine. It isn't just some kind of souped-up tea kettle. Pinhole leaks can amputate fingers, at high pressures (and with steam, high pressures=high temperatures) you can light things on fire with the steam. And finally, like others have said: a boiler is a bomb. If he were to pressurize that tank with air to ~3000psi and then break the valve off that tank would zoom around his shop causing havoc... If he pressurized it to half that pressure with steam and something went wrong, that could very easily LEVEL his shop.

@@DerrangedGadgeteer I already acknowledged that it would lose pressure as it loses heat, but again, that loss isn't as fast as you might think, and this tech is at work even to this day. I'm also not saying to get steam pressure all the way up to three thousand PSI, even if the tank could take it. Say he had a similarly sized static boiler that got up to about a thousand PSI before a safety valve kicked in to release pressure. It could be left with a heat source to build up again, so it just maintains at that level. If he then brings the engine over and connects, that thousand PSI now occupying twice the volume halves to around 500 PSI. He disconnects the line, goes off and uses that pressure in the engine while the boiler charges up again. Not as high as the tank could handle, but higher than the compressor can get. Yes, it would require careful building and testing of the equipment, but everything in the shop has the potential for danger, including what he's built so far. Anyway, he asked for ideas, so I provided one. Whether it's one he uses is up to him.

I had a Bellis & Morcom high pressure compressor installed to charge the engine starting tanks on a testbed for Napier Deltic engines. It was a pretty large piece of kit, around 1m^3 and it hooked up to a pretty hefty three phase supply. This used to take around 45 -60 minutes to charge the rack of six cylnders upto 250 bar. High pressure always equates to low flow when it comes to compressors so you may just have to accept long charging times if you want to charge to high pressures. I think you may be better directed to go back to you flash boiler project and run Torrnado on steam, not last of all because the cost of charging your air tank is going to be significant.

Steel cylinders will rust from the inside if there is any moisture at all in the supplied air and you really don't want a cylinder failure, they tend to go off like a bomb. 220 bar is roughly 1.5 tons per every square inch of cylinder wall, 300 about two tons... that's one hell of a big bang if it lets go and I'd prefer to see a lot more of your excellent videos :) Cheers :)

The options I see for Tornado; Getting a high volume high pressure compressor or adding a tender to Tornado with a very large low pressure tank or tanks The hybrid options; Adding a tender with your compressor on it powered by a battery/inverter setup or adding a tender with some vintage engine running a compressor Maybe the added tender could be at the end of the train becoming a caboose. Fun project, looking forward to all your videos.

Quick project idea: make a tender with a compressor for tornado, maybe a spare parts box and and a spare tank, a layer over to protect it and a few hinges so it’s a trap door,

In the fire service, we use a “cascade” system to fill the SCBA’s. This involves filling several tanks one at a time in series, then combining the outputs together to receive the necessary pressure. Might be an angle to check out.

Not how a cascade system works. You are equalizing bottles with one large bottle (higher pressure) at a time until the small bottle (lower pressure) is at capacity.

Well done to Vevor. Although the compressor wasnt a match for this application it does show what good gear they sell. I was highly impressed with the mag drill.

The tank is rated for higher bars. The machine only needs 120 psi to run. With 120 psi it can run for about 2 mins before it uses up all of the air pressure. With 4000 psi it would last far longer. The Vevor machine is or was suppose to fill the tank up to the max pressure. Yet it takes so long to do this because it is a small compressor. If the bottle was just 1 liter it might fill it in a couple mins. Where this tank is 100s of liters.

The water pressure forces the air to compress, and eventually enters the pressurised tank.

I'm using my well pump to pressurize a compressor tank with water and air. this way we don't need a water tower. the gauge sometimes reads about 3 bar before the pump shuts down. But we use for safety garden hose couplings as well. these separate from the tank at just over 3bar. we don't want to blow up the garage with the water tank. at one of my early tries I managed to get the pressure about 13bar. very scary as the thank is rated for 15 and half a century old.

I think you can make it fill the tank 8 times faster if you connect your regular compressor to the intake of the vevor compressor. This way the it gets fed with 8bar which means there is 8 times more air inside the cylinder of the vevor compressor for every stroke. But of course it will also produce more heat while running so you should watch the temperature when testing!

Something that gets up to that kind of pressure these days cost thousands of bucks. The majority of 1/2/3 cylinder compressors do volume at 120 PSI but you need up to 400 PSI plus volume too.

Been a while since we've seen her! Great that she's still running fine!

Try a leaf blower into the intake of your stock compressor, that pumps via an intercooler into the SCUBA compressor. Some commenters have said the stock Vevor dryer is not up to the job, so get a bigger one. Definitely recover the exhaust from one piston/cylinder and pipe it to the other cylinder but make that twice the diameter. I'd also, for more efficiency, make the pistons double ended. More complication but that's why all steam locos have them.

Great to see you giving the thing a try bro. Safe travels. Ken.

Tim, brilliant video. The benefit of a compressed air system is you can utilise energy of other sources. Having a conventional compressor defeats the purpose I think as the train is just using the small electric motor on the compressor indirectly with inefficiencies. How about building your own pump and using that lovely big diesel engine you have? I've been experimenting by building my own pump using small diameter cylinders and one way valves. The hope is to use wind, water and steam to create compressed air for the workshop and other things. I can email a list of parts and a picture of what I've been working on if you like? Cheers J

While you are correct that the small electric motor would be more efficient powering the vehicle on it's own, you would need a large portable battery to power it that would take power to charge anyways. The air tank is simply an alternative way to store the energy coming out of Tim's electrical outlet. A battery will eventually lose capacity and need to be expensively replaced anyways while an air tank can last much longer despite its inefficiencies. It's the practicality of a compressed air system (as counter-intuitive as that sounds) that Tim likes due to his rural location and low budget. I do think trying to utilize the big diesel engine is a method that has potential. This would mean that the only thing Tim would have to find is the actual pumping part of the pump. The big diesel engine could take care of the power needed.

I had a natter with the driver who explained that they were in fact compressed air engines.

I don’t know about where you live but in my area we have welding shops that send tanks out to be refilled. Usually you just exchange your tank for a full one. Nitrogen would work well for what you are doing.

I have a great time watching.

So, I'm gonna go with a neat trick I saw when I worked for a short line railroad in New York State... To accomplish the hydrostatic tests on our steam locomotive boilers, we used a special pump that used regular 130psi air to compress water up to 360psi water pressure. A Westinghouse 9in air pump had been modified to run on air on the steam side, and the old air lung had been replaced with a simple plunge pump and a set of check valves. When the pump pulled back, the plunger pulled water into a 1½in diameter pipe with an ~9in stroke. The pump then switched directions and so the check valve on the feed line side closed, and the water was pushed out to the boiler. With this we pressurized a 1000+gallon locomotive boiler for our government tests.

Do you have free flowing water on the property, or a means of creating water height? Say a windmill water pump to a water tank at a higher elevation? If so you might be able to at least feed the vevor at higher pressure. There is apparently a device called a trompe hammer, that combines a trompe with a water ram pump such that the ram effect boosts a conventional trompe. An alternative arrangement is being commercialized by a company called Carnot Compression, which effectively shrinks the effective height of a trompe, by embedding a trompe in a disc wheel and spinning it while feeding air/water from the center, which flows radially out of the disc at greater than one gravity, increasing effective water head.

I've compressed air within 2L carbonated drinks bottles by connecting such a bottle full of air upto mains tap water. Volume of compressed air at end isn't much , and pressure limited to that of tap water.. Connecting a pressure washer upto a tank in which air is to be compressed might work.

Love to see Tornado again! I hope the garlic process is going well :D

We use twin head regulators at work similar to the setup you have. As the output gauge is deviating with each piston stroke, I suspect your regulator isn't allowing sufficient volume of air to the engine. The question is whether that's down to the cylinder essentially running on fumes at just 120psi and its not enough for the high pressure regulator, or down to the design of the low pressure regulator. One of the uses is blowing optic fibres from a dry air cylinder, normally we use a compressor directly and that requires 70l/min at 145psi, so I would guess the regulator we use can keep up with that flow rate. If I can find a set of gauges I'll post again with the spec.

You should try making a tender with one big tank or multiple small ones. Just the single one on the locomotive is obviously not enough to keep it going

Have you considered making tornado more efficinet in tye first place. A larger bore cylinder with a shorter valve open time (ideally variable like steam locos). This would allow the air to expand as the piston moves and exhausts at much much lower pressure as opposed to keeping the high pressure the full length of the stroke. .

In order to make Tornado more efficient, give her a tender sort of wagon, with an extra air tank, and maybe somehow, an air compressor.

Use the Big low pressure compressor to feed the input side of the small high pressure compressor? That will short cut the work the small compressor needs to do from atmospheric and gives a head start.

Really great video! But I'm kinda thinking of what about smaller tanks that will hold more pressure than the current sucba diving tank you have?

Well it looks like time to build your own compressor! Obviously this is an energy rich endeavour so maybe an add on to your existing engine? One way valves are easily made with a ball bearing and a spring in a suitable enclosure (easy for a man with a lathe) The hard bit would be seals around your compression piston. This could be long throw low speed and immersed in oil (does not compress) so as to transfer the energy into a displacement cylinder! Alternatively you could have a trip to the fridge recyclers and pick up a few of those compressors and put them in parallel to get increased output (they are low volume high compression machines) Glad it is not me doing it though! All the commercial compressors I have seen put out a lot of heat! Compressing hot air is a bad idea!

You need a dual setup. First 8 bars should be filled with regular large compressor and then further pressure should be topped off by high pressure compressor. Not only this will work faster, it will also distribute wear between two compressors too, making them last longer. Don't forget about water inside the pressure tank that tends to condensate as pressure rises, seen many tanks rusting from inside out because it wasn't taken care of properly. The problem will be automating the whole process but it's definitely doable.

How about converting an old petrol engine into a compressor and hooking it up to your one cylinder engine group?

Good that you gave it a try. My suggestion is to leave the high-tech route and try a long lever, pressing on large bellows. Using wood and/or steel. So that a single person's weight is enough to lower the lever against the already present air-pressure. With a 'see-saw' construction, two people can give a continuous flow.

One option for powering a locomotive that I don't remember seeing in the original video is catenary electric, running off wires strung above the tracks; you wouldn't have to worry about charging batteries, or pay for batteries either, and it is quiet. I'm mentioning it now because KZread has recommended me some videos of people using it successfully at about your track gauge and weight: pulling a train: kzread.info/dash/bejne/gH-iu82QgsbgpJs.html information about the cables and current collectors: kzread.info/dash/bejne/p3tqmauqkpzIYMY.html&t

I would have expected a small pick on the high pressure needle. Wouldn't the Vevor show even a slight pick on its needle with the valve closed to the air tank? Something was wrong.

not that this is about the problem at hand but I suggest making some additions to the charcoal plant to capture the wood gases it emits. use these to fuel a petrol generator, or just burn it for cooking or hot water..

Would a second or third cylinder help? Even one converted from the orange door stop propane one? Or could you recycle the used air almost make a triple expansion engine? Just some thoughts.

If I couldn't find a high pressure compressor at auction I would probably try using a hydraulic ram to force close a high pressure air ram, with a check valve on the output so the air couldn't return to the ram from the tank after each cycle. But I think it would be slow and tedious!

What if there was 2 hooked into the tank and a flat bed coupled behind so to keep going while do work

what pressure are you looking to achieve and what is the max pressure you want your system to have?

The machine runs again

Connect the vevor's air intake to the 120psi compressor air supply. That'll speed it up a bit, also might re-shape the internals if they aren't strong enough, but if it really does go to 4500psi then it should be fine.

All of the pneumatic quick disconnects leak air. Even the best ones. If you don’t believe it plug a pressurized male and a female together and immerse them in a bucket of water and watch the bubbles. They are not designed for what you expect from them. Additionally although some of the flexible hoses or tubing that you were using may be rated for a certain pressure, the connection with a hose clamp is the weak point and certainly a potential leaking spot but more importantly blowing apart.

this may sound silly but what if you build a diesel powered compressor then put that on a bogie then directly hook that up to tornado

Would it be possible to have a compressor charge a static storage tank for long periods/continuously and then top up the loco's tank from that? I don't know how these things wear but if it could take it, would also mean potentially charging the loco tank faster (although you'd need to keep the storage tank at significantly higher pressure or have it be absolutely massive if my understanding is right)

Have you looked at scuba tank compressors? Have you looked at cooling down the tank as you fill it? I know they submerge scuba tanks when they fill them.

Could you build a compressor that runs on the old engine you have the charcoal grinder hooked up to?

Use shorter cylinders and mount them to the frame with moving drive rods. That will cut your use of air down and also add to Tornado's power

Some of your viewers must work for Aer Lingus. Is there an old F27 ground compressor out there or even the compressor from the aircraft auxiliary gear box available? At Jersey European we used a scuba tank compressor powered by a little Lister diesel engine to top the aircraft pneumatics up each morning.

ah this old problem, how to create large volumes of high pressure air... these pumps use a dual cycle, the lower half is conventional, but the piston has a long thin rod, it compresses this into one of the pipes going round, then that goes into the secondary piston up top where the long rod compresses it further to achieve huge pressures relatively cheaply... the key is aspect ratio, long thin piston = higher achievable pressures, but lower volume... i've seen success making a form of "radial engine" out of high pressure hand pumps and just spin them like billy-o, perhaps it could be something mounted to that big flywheel of yours to create compressed air as the engine runs, who knows... key points; 1. aspect ratio, long and thin 2. want more volume you need to scale the whole thing up, and the input power required goes up exponentially 3. it gets very very hot! you need to actively cool it 4. in terms of efficiency, feeding the long piston with already compressed air will dramatically increase it's output at higher pressures, diminishing returns as you get lower 5. these designs of dual compressor have exponential returns at higher and higher pressures, and diminishing returns at lower pressures, so do the math for best performance this particular system works in reverse for full size steam engines where the main two pistons dump exhaust into a central third piston that leeches more power before finally releasing the exhaust at near ambient pressures... otherwise the 90% of the length of the long thin piston would be used just bringing the air up to 100psi, meaning the resulting volume at pressure is very low, if you feed it 200psi to begin with, then the full length goes to further raise the pressure... so i would do some math and work out precisely the dimensions of the pistons needed to create the air required at the pressures desired in a desired timeframe... you can calculate it all prior to making anything, i would however overshoot the initial intake volume as losses, leaks, and ambient pressure all play a role... over shoot the intake and overpower the compressor motor and you should be golden
