I don't know if I have ever introduced you to the other side of what I make, all my life has been centred around model boats and model engineering. I have had to give up model boats recently, due to health reasons, but I still design and build my own model engines. But not the normal variety, I go for things that are slightly different. This one took about six weeks on and off, and is made out of recycled materials, bought from the scrapyard, or given to me, or scrounged from wherever I can get it, nothing is sacred, I will use almost anything in my engines. Except the fasteners, I like them to look pretty.
This is my latest creation, and at full wack should reach around 30K RPM.
This is running around 12 to 13K.

A long intro, but well worth the wait.

BTW, this is a prototype test bed for a matched pair to drive a 10ft destroyer using steam.

I have just finished watching all your youtube videos. British engineering at its finest.
Great work sir.

John, A superb piece of engineering and a great credit to your talents. Two of those in a destroyer model would be quite a sight but where are you going to keep a ten foot destroyer?!!

Richard,
I was commisioned to build two for a 10ft destroyer by a gentleman in the US. But I stated a prototype was needed first, to give me some idea of power output and what speeds to expect. You have seen the proto.

He is hoping to run them on steam, but I have already informed him that he would really need to get a flash boiler built, to give him the volume of steam that will be required, so the decision will be his as to whether he wants them building. They will be, by going from the results from this one, about 2/3rds the size, with only two rotors, and the rotors will be made of much lighter material. I can't use aluminium because the steam impingement will almost just blow it away, so I have some pieces of titanium, or maybe obtain some ali bronze to do the job.
This one isn't lost, it will go into my ever so slowly growing collection of home mades.

Have now got to get my backside into gear and get a bit of my backlog cleared. I hope to start on a new design in about two months, but I don't know what yet. I have got a load of material to start my onslaught into the stirling engine field, so maybe that will be next.

Glad you gents liked it, and thanks for the most welcome good comments.

Hi John. I thought that instead of the usual greatness icons that would simply never do your work justice, how about a beer or two!!! Well, only after the project is completed! I can;t wait to show my friends this! Take care, Jeff

Great work there John,

Have just watched the video too and can only say I am very impressed indeed. Nice machining work and even without full pressure, this certainly looks a capable engine !!

Regards.......Mark.

Excellent job John,

What a small world John, Are there no end to your talents ? I am at a loss as to how you manage to fit in all this marvellous engineering work and find time for the immense amount you do for online communityies, even with mrs john taking care of her normal duties, you must have thirty hours in the day oop noorth there.

Kind regards

Malcolm

Malcolm,

Anyone who knows me well will tell you I don't have enough time in the day.
About four hours sleep is normal.

Looks like maybe the destroyer might have sunk, the steam consumption for two of these engines looks to be a might bit impossible to keep up with in such a confined space.

Having to stop soon, full rebuild on the workshop and machinery change, about 2 to 3 months.

John
