In my post above, the two vids were deleted, so if you are still interested, this is a silly one showing both in the same vid.

YouTube - My own designed turbines

Many thanks,

But I don't do it for praise. It is all to do will preserving a tradition.

Home machinists (and even industrial full time ones) are a dying breed, whether CNC or manual, and it...

If you want to see a site that is dedicated to sharing things, including all of his own designed plans then look at Jan Ridders site.

Ron,

They are very easy to make, especially if you are using CNC (which I don't).

You just have to keep an eye on tight tolerances and balancing.
Plus of course you need fairly good, high...

Rolf,

A very novel concept, and I am sure, even though you found nothing on your web search, someone has tried it sometime over the last 300 or so years. Maybe it was such a dismal failure, it was...

When a person asks for help, I think anyone with a sense of assistance would reply to their plea.

But why oh why, when you reply to their cries for help, you get no response back. It is only...

First thing you need to do is decide whether you want to do an impulse turbine or a reaction turbine.

Impulse turbines are are a lot easier to make and can...

We have just moved our site to a permanent one after 6 months up and running on a free site. Your thread has already been mentioned on there.
Please feel free to come across and check us out.

Looks like the site has gone bump anyway.

This is mine,

Expect a lot of sleepless nights as you try to set it up to run.

Seeing that you have already had it running well, the only real thing that can be the problem is the spring tension. Just apply continuous pressure (not too high), and then starting with the spring...

Please take note, read the small print.
This site is $12 for six months only, then another payment is required to carry on using the site.
Most of the plans can be obtained elsewhere totally free....

Hi Capt,
No trade secrets in making small, well adjusted lathe, razor sharp tooling and no drinking the night before.
BTW you don't need a micro lathe either, this is a 10" swing nearly 70 years...

Here's mine, 1/16" to 3/16" in 1/32" steps, two different radii, but easy to make whatever is required, just six rollers. Less than a day to make.
Nowhere near as good as yours but it does the...

Hi Mcgyver,
While you are still making your flanges I've been quite busy.
Finished making the prototype piston valve engine, and I customised the second one I made in parallel (first picture), also...

Point taken.

Mcgyver,
Awesome, impressed, drooling down my t-shirt. You have made all the bits that I don't like doing, so send it to me and I'll finish it off. Just one problem, will it fit into my model boat....

Hi Geof,
Most of the twiddley doodah bits in an engine cab (at least in the UK) of a locomotive are to alter the timing of the steam inlet into the cylinder. Say when they pull away they wack 100%...

Hi Mcgyver,
Nice to hear from you again. The only grinding I did on this one was the main cylinder block, the rest were as they came off the machine plus a bit of emery or steel wool.
I'm still...

Here is another little update.
This is one with a couple of videos of my own design 10mm bore by 20mm stroke piston valve steam engine. It still needs the control valve designing and making....

If you go to here and go to the bottom of the page you will see the Halo, they are supposedly doing a set of plans that can be made as either 2,3,4 or 5 cylinder. The vid is eye opening...

What do you mean by a push rod engine, is it one using valves like a piston engine or do you mean one like the one I am designing and making as I go along at this post here - ...

Just a little update on the engines I made. I decided to convert one to a horizontal engine for fitting into a model paddler.
It was a quickie exercise, with the criteria that the engine can be put...

Hi Nick,
Hopefully I won't be using piston rings on the piston valves, I hope to get the tolerance tight enough that the oil will make a good enough seal, but it will have a gland on the bottom and...

Hi Nick,
Thanks for the compliment.
At this moment I have the engines being run on steam, and everything as what was expected, they run really smooth and powerful on 25psi (2 bar), with good...

For those interested here is a short video showing the bedding in of one of the engines.

Here is a finished engine.
Already had successful run on air, steam trials over the weekend.
A nice slow runner, just a bit tight, needs to bed in.
First pic showing inlet side, second showing...

Just buy yourself the smallest centre drill (slocombe drill) and just touch on, this will give you a detent to start your drill. The reason you want to touch on is I think that the smallest tip point...

Hi Donald,
I was looking at your web page and couldn't help noticing your problems with your flycutting. Who told you that you should only be taking cuts of 1 or 2 thou. I regularly take cuts (ok I...

Just an update on how the engines are progressing. Nearly finished, just baseplates (couldn't be started before power takeoffs were made) and a bit of shafting to make.
Here are piccies of the now...
