It is great to see what you are doing from close-in and hearing your thinking at the same time. Appreciated. Thanks very much for your response to the suggestio about the upside-down fire method!!! Trevithick would give you his thumbs up for working with 'strong steam'.
Thanks! Yes the boiler is fitted with superheaters, the steam temperature is shown on one of the readouts fitted to the left hand side of the backhead during tests.
Pity I'm at the top of the country, I'm retired fitter turner, could give you a hand as quite interested in steam especially as marine propulsion. Steve
Hi there, Can you explain what condition you are designing this locomotive to run (freight or passenger work, long distance, main line or preservation work? And so on).
I believe he's said before that the locomotive will be a 2-6-0 meant specifically for light passenger work, but could possibly haul a very short freight train
If it’s for light passenger work what engine is it replacing? How long is the Journey?and conditions? And how light is light passenger work (150 tonnes 200 tonnes?)
@@Mackwell-Co Hi there I understand what you have specified but is that the actual working conditions? And if 150 tonnes is all your designing for that seams very low when compared to old machines like the Hunslet austerity could pull 400 tonnes up steep gradients while being smaller then your proposed design. I would love to see you succeed in your goal but I feel that your specification may be too limited to make your engine a practical alternative for enough railways to make a difference .( I am viewing your project from the expectation that your planing to replace multiple existing locomotive from a variety of railways not just one engine from one railway)
Thanks, Adam. The Hunslet Austeritys are significantly larger locos, weighing 49 tonnes, 26% heavier than the Mogul and 100% of that is adhesive (170% greater adhesive weight!). On the other hand, the Hunslet has just 50% of the fuel and water capacity but is designed for a different purpose. The Mogul is just the first step and is tailored to the NZ scene, where it will cater to the demands of the majority of passenger services without the limitations (range, fire risk, pollution etc.) of conventional steam locos.
This is amazing! It’s too bad everyone is being duped by electric, steam is an extraordinary source of power and I’ve been dreaming of building a modernized steam tractor! I’m learning a lot, I’ve never heard of a water tube boiler up until this point. I’m a steam boiler operator and I currently operate 4 fire tube boilers
A suggestion for holding those small parts, or larger ones, is to use an electromagnetic vise or hold-down. I made one out of low cost mag-locks used on electronic door locks. Mine cost about $60 US. It's powered by 12 volt dc and will hold 1200 pounds. When a piece of steel is locked down it is held solid and all.you need to control it is a simple single pole switch and a battery of power supply. It really doesn't need much power to hold.
I have a design for a different type of cylinder which may offer many advantages. Would you possibly be interested in developing it?? Thanks. Love your project.👍🏻
You not only have to develop steam pressure, but steam volume.From your description of the water tube section it looks far to small to create a sustainable volume of steam-VS the bulk of the boiler. Great workmanship---I hope that when you couple your boiler to an engine you aren't disappointed. I have some experience with steam cars (Stanley)
This is very interesting I enjoy watching these vlogs this steam tractor would be good if it had four whell drive four wheel brakes and four wheel steering this would be the first four wheel drive tractor from .Jeremy mellor england would it be possible to make a up right boiler
A boiler can be any shape that allows efficient flow of combustion gas and steam. Check out the top fired quick response steam generator of the Doble steam car. en.m.wikipedia.org/wiki/Doble_steam_car
Is there a reason for using TIG over Stick Welding? Just Curious because I've heard some old heads swear by Stick Welding Nice work so far, love your choice of music, can't wait to see more updates!
Thanks! TIG is good for this finer detail work where I need to be certain that the as designed weld penetration is achieved. TIG is hard to beat for accurately tacking parts together like this, and there's no mess. I may run some of the caps with the stick welder but in any case there is plenty of stick welding to come!
As much as I love steam the reality of "sustainable" steam is a central power station and electric locomotives. They simply aren't efficient and never will be. Any one who disagrees needs to read a really basic book on thermodynamics.
Large steam power plants which power electric trains may be the most efficient system, but the fact of the matter is you are going to have a hard time electrifying every piece of track in the country. Steam powered locomotives will b a good stop gap when diesel becomes no longer viable and fossil fuels run dry.
I can't understand why electric trains don't have solar panels on their roofs for partial electrical supply, maybe charging batteries or direct use on sunny days?
@@donotwantahandle1111 it can't run solely on the solar panels. Think about this, how many solar panels do you think you need to pull a fully loaded car? The answer is too many for the little roof space a car has
I read the technical specifications for your loco and they look pretty good, especially the range and axle weights. As you’ve said, changing just one major component- the boiler- rather than change everything makes good sense. No doubt you have thought of loco names... but if you are open to suggestions let us know😊🤔
Why are your chamfers so deep. You don't need it that deep unless you plan on filling it with weld and grinding all those joints flat. You also forget that the hotter the steam, the more energy you get out. Triple expansion engines were tries and so was this tried in much larger far more powerful enings for rail engines. Generally it didn't work so well. The general rule of fires is that heat rises. SO - you start with the smallest stuff underneath the larger material so you can heat the larger material until it becomes gaseous and burns. There is a reson why fires are started this way and this reason has been in use for about 100000 years. Did you really think you were going to defy convention? My question is a simple on. Steam locomotives were in use for about 150 years. There were all sorts of configurations for boilers and cylinders. That is all that matters, really. It seems to me that just about every possible configuration of boilers was tried yet you think you have finally found the best way. Vertical boilers use water tubes to aid in circulation of the water/steam cycle. Horizontal boilers are almost always fire tube and this has come from 100 years of research and development of some very efficient boilers built by well established companies and put to use in some very important applications. Steam turbines for locomotives have already been tried and discarded. Piston engines rarely get much over 30% efficiency. What have you got that major industry, that would profit handsomely by more efficient systems. Profit is an incentive to improve. . Mind you. I believe in steam engines and morn the passing of locomotives powered by steam. It was not the boiler or the pumps or cylinders that failed. In fact, Big Boy is the epitome of efficiency. It was the maintenance of those engines that made them impractical.
I honestly can't wait to see this project kick off. It really deserves more attention than whats got at the moment
Even for a nuclear power station, it all comes down to a steam turbine to spin the alternators. We remain in the steam age :-)

Very nice work sir.
Congratulations from Jaffa’ town 👏
The craftsmanship is amazing... I’m subscribing 🚂
This is incredible. Steam engines are amazing machines! Are you adding superheaters into the boiler?
Thanks! Yes the boiler is fitted with superheaters, the steam temperature is shown on one of the readouts fitted to the left hand side of the backhead during tests.

Wish you'd wear a dusk mask/face shield when grinding/wire brushing. Very nice tools & machines in your shop.
All the best, Pete

Great idea, we have an old mag drill so will investigate using the electromagnet on that - Cheers!
Should have got your water jetting done on an Omax with tilt-a-jet. Will make perpendicular edges on >8mm material.
I have a design for a different type of cylinder which may offer many advantages.
Would you possibly be interested in developing it??
Thanks. Love your project.👍🏻
Idea maybe add a hydrogen nozzle that sprayers hydrogen on the fire inside the fire box to make it go faster
Good...
