I'm very impressed by Mr Appleton's skills in growing 15mm copper pipe. I put 2 inch of pipe on an engine and it stays that long for years. Must be the weather up north
Loved your videos on the build of the Stewart A5 engine. Excellent work. I could watch it all day. We have very little of this here in Western Australia. Thanks Emil Pilkiw.
Hello Mr. Appleton, I am a new guy to machining. I FINALLY have a good lathe and mill. all of my life I have wanted to make / machine a presentable steam engine. I have bought 3 plans from Stuart of engines that gave me a woody. (I'm 74 - so that's momentus) I just wanted to say THANK YOU for your method of teaching. Every video that I watch of yours, I Learn . tanks for your efforts. Wm. Miller
Sounds and looks so much better on steam rather than air. Fantastically smooth working and beautiful engine, Mr. Appleton... Impeccable work, as usual.
Bonjour Keith, Once more, great job. Now, you just have to build a 4 meters launch and an appropriate boiler to take the benefit of this "Swiss" steam machine. Amicalement, Raphaël
Amazing, I find it so easy to steam my models , on a full size site warming up takes nearly a hour ! We warm the 3 inch pipe then the six then the 12. Great video
@@keithappleton hi Keith Appleton I'm looking for a Stuart turner 5A that I want to know if you're interested in selling it I need one for a 14 ft shamuno aluminum boat
Wonderful... Was hoping you would show it under steam. Can that 6"? boiler keep up with it running at higher RPM for a while? Think you will be able to run Ken around the garden before the weather turns?
Wonderful job restoring this Stuart 5A to proper running condition. Is it just me, or do these little engines sound different when running on steam and compressed air?
Very nice. It runs quite smooth. I always like watching them run under steam rather than just compressed air. How would you handle the steam exhaust from the engine? I always enjoy your videos. Thank you for making them.
That exhaust pipe drove my OCD nuts through most of the clip- I dunno whether to say thanks or curse you for fixing it in the last shot! :v Either way, thanks for another clip of your awesome work! Have you considered using the 5A as the basis for a small boat or canoe converted to paddle-steamer duties?
Very nice Keith, alway enjoy watching your vids, I also have stage light and sound equipment in the shop for you never know when you need it hahaha. Making the reversing gear is the next thing I will be trying to make for my 5A
Hi Keith. Would a couple of 5As be enough to power a very small road vehicle do you think? Something similar to a steam speeder but on the road instead of the rails. Kind of a steam powered kart type thing. Just toying with the idea, as Grandad and me are making plans to construct our own 100psi boiler next year. :)
@@keithappleton It says 100psi on the website i think, not too sure. But still that should be plenty of power to move my large arse about on tarmac If only they made them in ready machined kits. I havnt got a laithe.
I noticed that steam engines either have a small boiler or a too large one. Is there a "rule of thumb" that would tell you that you need a 1 liter or 2 liter boiler? Ralph
Ralph McCoy I think it was in a Machinery Hand Book, that spoke to the sizing of boilers. It has been a long time ago that I read it. But there was something about GRATE size. And how the HORSE POWER of the boiler was calculated. It seemed to me at the time that a boiler could be rated by Hp... was odd. But yes.. there is a trade off,,, If the boiler is too big, then it will take too long to raise steam. And if it is to small, as in if you try to run a 100 hp engine from a 5 hp boiler, then you will only get 5 hp from the engine... But, as in most cases, the ideal is not needed, to make things work... I hope this helps...
Ralph McCoy Yeha, , I googled it... And this is some of what I found, it may or may not scale down. But it is someplace to start.. From an engineering standpoint, a Boiler Horsepower is the ability to evaporate 34.5 Lbs Mass of water, already at 212 Fahrenheit, to steam at 212 Fahrenheit. We are measuring only the Latent Heat of Evaporation. A Lb. Mass of water takes 970 BTU of heat to evaporate it. If we multiply the 34.5 X 970 we get 33,465 BTU of heat = 1 Boiler Hp. I hope this is helpful. ..
It depends on the load, if you are just running it on display it won't take much power to turn it over. They are an external combustion engine, the heat source is what gives the whole system power to run. Steam engines can consume an incredible amount of steam under loads. If you have an undersized boiler and are loading it you will have power for a bit and with the heat maxed out your pressure will drop off and you will have to wait for it to build back up. For a practical demonstration watch some of Jay Lenos steam car videos the 1925 Doble is a good one. As for calculation for sizing I would have to do a google search. It shouldn't be too complex to go from btu's to hp, this type of steam engine is around, if I remember right, 25% efficiency or there about. I'm almost hesitant to say that 25 because its been so long and I couldn't find a reference. For a rule of thumb, maybe you can see what other people run? If they don't say you can figure out rough size from knowing how big the engines are and extrapolating the boiler sizes.
Curious... What kind of load can you put on this to power something? I know you said this is a full size steam engine. Would it be possible test run on something in a video?
if I had something ready made to power with it, but I do so many engine repairs and rebuilds I don't have the time to make anything to drive with the engine. It would easily power a 20 foot river boat - according to Stuart Models, it delivers 1.5 Hp at 80PSI boiler pressure.
I think it's very likely that this has been my favorite of all the refurbishment playlists I've seen to date. Thanks very much for making these.

Another fantastic work of mechanical art from you Keith. Thank you for posting these videos.
That engine is really entertaining to watch and to listen to!
Thanks Keith! Pure kinetic poetry.
A smooth runner. Job well done sir.
Awesome. You do great work and thank you for your videos
Congratulations on a successful test Keith. I'm very happy for you. Good job 👍
Amazing, I find it so easy to steam my models , on a full size site warming up takes nearly a hour ! We warm the 3 inch pipe then the six then the 12. Great video
Yes, steaming the full size is an entirely different technique . . .
@@keithappleton hi Keith Appleton I'm looking for a Stuart turner 5A that I want to know if you're interested in selling it I need one for a 14 ft shamuno aluminum boat
Keith, you need a longer exhaust because the condensate splashes on the flywheel below. Beautiful model and so smooth running...
as soon as it cooled after steaming it, I made a longer exhaust pipe {:-))))
Keith,
WELL DONE..just watched the series start to finished...Very Well Done Indeed
Looking forward to more of your videos
Mike
Great to see it in steam Keith - another job well done. :)
That turned out real good thanks for sharing all the best from John in Texas
Awesome job ❤
Thanks 😄
@@keithappletonI really enjoyed the whole series. Thank you.
Always useful, educating and entertaining. Thank you very much.
Very nice Keith.

the sound very different on steam - it's denser ....
Thanks! Glad to know it's not my old ears playing tricks.
Wow! Must build me one like that too! Didn't know this is how copper tubing is produced ;-)
Great job. Love how big it is.

I don't have the spare time what with making all of these videos, but it has crossed my mind though .....
Very nice Keith, alway enjoy watching your vids, I also have stage light and sound equipment in the shop for you never know when you need it hahaha.
Making the reversing gear is the next thing I will be trying to make for my 5A
I always thought England was so green because of rain. It looks like it is from the remains of all that steam! (Ha).
Stunning.. is there a Mrs Keith Appleton? if there is she must be very appreciative of your hobby!! ;-)
Not at the moment - she now lives somewhere else - it was either that or the Acid bath }:-)))
All that gleaming metal is so pretty. It's like a piece of jewelry that moves.
Very nice engine .one question ...how do you tell which way is forward and which reverse or does it not matter?
It doesn't matter really.
Strictly speaking, it doesn't matter until you use it to drive something.
Hi Keith.

I would think so - each will deliver 1.5 HP at 80psi ......

Gorgeous.
I noticed that steam engines either have a small boiler or a too large one. Is there a "rule of thumb" that would tell you that you need a 1 liter or 2 liter boiler? Ralph
The bigger the better ...... volume is what you need - but you always need an adequate heat source to make it work ......
So bigger than you need is OK but too small is no. As long as you have a heat. thanks Ralph

So it looks like the exhaust is making a mess, as some have noted. What is the cleanup process after a test like this? Not your pressure washer.
A cloth .......
Have you ever thought of building a scale traction engine that would be a very interesting video
I used to have one - please watch my videos ......

I really like the oil pipeing

That there's a thang a beauty. Mighty fine.
Very nice
Trying to post a picture but that does not seem to work 😉
That's better than watching paint dry!
Good looking machine.
Doesn't all that oil leave dead spots in your lawn?
no
So, that's a boat motor then?
Yes, used in Steam River Launches up to 25 feet in length .... 1.5 HP @ 80 PSI
Why don;t the engines never drive anything ?? have them so some work ?
If only I had enough time to make something to drive ...........
It was driving an oil pump though....
(lol!)
Your microphone needs a dead kitten but other than that, thanks for the video! :)
I have all that equipment too for my Sennheiser 416 microphone, but in this case I just used the camera microphone as it didn't seem that windy .....
imagine that engine in a kayak
it is more suitable for a proper boat 25 feet long ..... a bit too powerful for a Kayak I think.
