I think it's very nice seeing these two engines run in unison next to each other even though their mechanisms are so different. I know next to nothing about steam engines, and all I know I've learnt from this channel. One day I might try my hand on tinkering on a simple steam engine myself, but for now this is just one of the channels I watch semi regularly because I enjoy watching people skillfully building things with their hands. Thank you very much, Keith.
Back in 1979 a friend took me to the Living Steam Museum over by Kew Gardens and for the first time in my life watched the starting and full running of a beam engine. As I recall,they pumped water for London from 1844 to 1944. Those massive engines were the rocket science of their day,and the detailed fretwork of the intricate cast iron was beautiful and amazing. The force each piston developed moving that massive beam and all related ironmongery was breathtaking. Looking at those model engines suddenly brought back a flood of memories. Making a video record of the details of each project is no doubt very time consuming, but I for one appreciate the efforts of both image and the craftsmanship displayed.Cheers.
I love watching these engines work! I'm really taken by the Cyclops. The geometry that allows it to convert the linear motion of the piston rod to circular motion of the flywheel is very interesting.
Thank you for another fascinating video. It certainly is great to see both engines running together both with and without the chuff pot. The chuff pot certainly looks nice, it's just a pity it is so noisy when it is in the system. I look forward to your next project.
listening to the engines you repair is great also if you did not get stupid comments from some of your viewers I think you would get no joy as your return comments are very good thanks for your vids keep it up
Just can't express how fascinating that Cyclops is. Especially when posed next to the Vulcan. More movements on the Vulcan and so smooth, but that circular motion on the Cy is just fantastic. - Is that "slight" rattle noise coming from the inner gear of the Cyclops? If so, would a more viscous oil quiet it down even more? - I know that having so much surface area of tooth to tooth contact between the gears must make it nearly impossible for it to be much quieter... ? Thanks again for sharing this craft.
Have you ever done a multi engine layout with the engines in series, exhaust from one to the inlet of the other? There is some precedent in industry for such an arrangement.
Does anyone know if the Vulcan is still available as a kit? I can find similar but the pics aren't the best so not sure if they're the same. New to the channel & binge watching galore!!!
No - as you can see in the video it is when the boiler pressure drops as water is pumped in that usually the Cyclops engine stops . . . both of the regulator valves are fine .....
I don't like people who make bad comments about KA. He's doing a great job. If somebody thinks they know better then they should make a video of their idea and send it in. Meanwhile here's a KA style girlfriend joke. My girlfriend is a magician .. She can make some really big objects disappear.
that was the colour that I painted my bedroom in and the pipe lagging is often white anyway (or sometimes silver) on full size steam pipe installations.
The way you do things those engines will never run >:) hehe That string you put on absorbs heat, and encumbers the flow of steam... Touching a flywheel is bad because the oils in your fingers causes build-up and strips paint.... Putting a steam whistle in a self made manifold is not efficient enough and will never work. Having engines on wood causes harmonics to transfer from one engine to the other and that's why one engine stalls when you start the other one. Man I can make up stupid shit all day, it's a gift.... (purposely being stupid and sarcasm often escape people so I better say it) "I am not being serious"..... EDIT: I really do enjoy your low-key style and your videos Keith, I watch after work, every day if you have a new one up. Keep up the good work bud
I had a similar though to that of the commenter you mentioned, but came to different conclusions. I somewhat agree with him that having the steam flow through the lubricator will quickly blow the oil into the outlet, but (unlike him) it seems to me this effect would stop as soon as the oil level drops to the outlet height. At this point it would behave like a normal lubricator, where the oil would be fed at a rate based on the accumulation of condensate in the bottom. Further to that, though, the flow of steam through the lubricator would keep it hotter than in the more common side-branch configuration, and this might slow down condensation and so reduce the oil flow rate. Whether this is true would depend on whether the condensate accumulating in the lubricator is only what condenses there, or also includes condensate in the steam lines that gets blown in.
you know, they really don't work like you think they do. Put it this way: Those Displacement lubricators work perfectly, (what more can I say) ...... they are the ones that "Cotswold Heritage" supply for their model steam engines and they look like they are "Jubilee Fittings" Displacement Lubricators. (made near Wakefield, UK) Choose any three of those reasons why the first chap who commented and now yourself think that there is some sort of problem with them ...... !!!!????!!!!
Keith, Don't get me wrong. I didn't say there was a problem with them! I was just musing on differences between using them as a side branch (which appears to be how the suppliers you mention designed them) versus using them as a through connection.
This is the very last comment I will make on here regarding the operation of Displacement Lubricators. It does not matter where the unit is mounted on the steam line or whether it's a T piece, or directly into the steam chest. Steam still condenses in the tiny hole that is cross drilled into the pipe that goes through the Lubricator. I will make a video explaining this in detail once and for all ....... because there is a lot of mis-information going on here . . . .
The Cyclops is fascinating. Keith - is the Cyclops more efficient in producing torque / power over other engines? I have not been able to find an tech literature comparing the hypocycloidal mechanism to more traditional one. Right now I am resisting the temptation to order one - though no one seems to sell them in the colonies.
Hi Keith Please don't think I'm trying to tell you how to do the job, I just have a question your experience might be able to answer. If the exhaust pipes to the chuff pot were lagged in string would they hold sufficient heat to stop the exhaust gurgling? Or is it just a generic small steam engine thing? Again, just an honest question, many thanks I really like your videos
No, it would still gurgle with this arrangement. My condensers don't gurgle because only the water vapour goes out to the chimney ..... but the condensing part of the Chuff Pot is not it's primary function.
I'm not (yet) a model steam guy but I find your videos interesting, very well thought out and presented, and I'm beginning to think about how I might get into this hobby, and with what ultimate aim. I've learnt a lot from your videos. But isn't it odd to have a model steam plant comprising a rocking beam engine - one of the earliest but important technologies - together with an engine that is a novelty engine of completely different type? You often comment about trying different assembly ideas to see that they look right, and not "odd" or "stupid", as you did in this series. This pairing seems decidedly odd. My ideal would be a model steam plant comprising boiler, appropriate pumps, feeders and lubricators, one or 2 engines of different size but realistically similar design era, and a gramme-ring generator or some such. Don't know how to go about the generator yet though.
why don't you tell your critics to go away in small hops (f off) I think no sorry I know your videos are great and love watching them and your comments are very amusing as an engineer myself I know the time and effort that you put into your models please keep up the good work the only thing is I am from Lancashire but have lived in New Zealand for many years all the best.
A thing of beauty is a joy forever.
Thank You!
Both beautiful engines in their own right but the cyclops is a star.
The whole setup turned out a real showpiece, nicely done.

Beautiful machines. I could watch them for hours. Thanks Keith.
No matter how tedious/boring of a job that lagging is, it's always such a satisfactory result!
glad some one else4 likes plants with multiple engines , I have four on one of mine with two interconnected boilers

In Brentford. I go all the time I live ten doors away 🤣
This a great video of a great looking steam plant! You do wonderful work!
All of those gleaming brass fittings ... How can a man not love it?
You always get a good laugh out of me Keith. Love the videos. Keep it up.
I love watching these engines work! I'm really taken by the Cyclops. The geometry that allows it to convert the linear motion of the piston rod to circular motion of the flywheel is very interesting.
1stPCFerret I seem to remember reading that this design was necessary because the basic crank was patented!
Thank you for another fascinating video.
It certainly is great to see both engines running together both with and without the chuff pot.
The chuff pot certainly looks nice, it's just a pity it is so noisy when it is in the system.
I look forward to your next project.
Very nice work, I'm glad you made the videos! Cheers!
I love these videos, Keith! Keep up the great work!
I guarantee when you Click the hate comment it says “no content” if they had any idea the work videos take to make they wouldn’t hate. Nice video
listening to the engines you repair is great also if you did not get stupid comments from some of your viewers I think you would get no joy as your return comments are very good thanks for your vids keep it up
Poetry in motion
Water closet run complete!
Lovely Keith 😊
Your speeded up pipe lagging would go well with the Benny Hill theme tune.
Very nice 👍

The centre gear does rattle a bit - oil quietens it for a while but then the rattle comes back ....
Sounds like a politician their full of hot air lol Very nice workmen ship old man Cheers.

No, I have never done that.
Does anyone know if the Vulcan is still available as a kit? I can find similar but the pics aren't the best so not sure if they're the same. New to the channel & binge watching galore!!!
Is there any kind of regulator for this, so the machines both can go slowly and steady for long time?
No - as you can see in the video it is when the boiler pressure drops as water is pumped in that usually the Cyclops engine stops . . . both of the regulator valves are fine .....
Very nice work, Keith, but I did rather hope that I would hear the chuff pot at work - I have never come across one before. Keep 'em coming.
Watching the video with my 3 yrs old daughter. She asked why he didn't oil the big engine :-)
{:-))) - you can't fool the observational skills of a Child {:-)))
I don't like people who make bad comments about KA. He's doing a great job. If somebody thinks they know better then they should make a video of their idea and send it in. Meanwhile here's a KA style girlfriend joke. My girlfriend is a magician .. She can make some really big objects disappear.
}:-)))
Will you video it running with the chuff-pot before you send it out? Be interesting to see how much louder it is. Thanks for the videos!
Oh .... go on then - please watch Part #9 . . .
Is there any particular reason why you use white emulsion paint versus any other color paint?
that was the colour that I painted my bedroom in and the pipe lagging is often white anyway (or sometimes silver) on full size steam pipe installations.
Would adding a super heater/steam drier help the boiler with running both engines at once?
It already has a steam drier fitted inside the top of the boiler.
The way you do things those engines will never run >:) hehe

Not really Mike, it just has an alternative to the normal way that the piston rod connects to the crankshaft, it is very nice to watch though .....
I always imagined lunatic asylum white to be more of a sepia tone, judging by all the photos of course :D
Your Asylum obviously needs re-decorating immediately ........ Sepia tone is soooo last year ........ }:-)))
Need more "Cyclops" videos.............:-) Just kidding.........they are probably rare.
Hi Keith, is there a bit of a knock on the down stroke of the cyclops engine or is it my bad hearing?
Yes there is. The centre bearing is quite slack.
Hi Keith

Oh, I got thirsty at 8:32...
But, I wanted a video of paint drying. You make me sad.
