Very nice Ray.
I've been trying to post a design for an alternative regulator that should be easier to make (and I think more effective than Stan Bray's), but it doesn't seem to work. It is the one on the drawing set for the 3 cylinder paddle engine. I've made several of these in different sized and they all work fine.

Woops! Just checked the download and the regulator is NOT there.
It seems that I can't post attachments - can you help Eddy?
I'll try again in a few minutes.

It's not working, and I get the following message

Send the file to me via email and I'll sort it for you Malcolm - eddy.matthews@paddleducks.co.uk

Eddy

spot on Ray, nice little runner.

Worth the wait thanks Ray. I can just imagine that this engine would run slowly under load.

Malcolm - many thanks for regulator drawings. Is this the one in the image you posted of your version of the Greenly engine?

Ray
Yes - I had forgotten that I had sent it to you. Old age; brain fade; you name it!
Please feel free to phone me if there any questions 01923 672341

Malcolm, I know the feeling . . . but actually you didn't, I found the file you uploaded yesterday! So you see, your memory ain't so bad as you thought!

I've been browsing your drawing for an hour or two. Seems pretty clear.  Probably make a start on it tomorrow, it's a good 'fill in' while I'm waiting for a start capacitor to arrive, (from Hong Kong of course) to fix my compressor.

Will let you know how it goes.

Hello from Austria!

Maybe a bit off-topic, but I remember - in the good old days of Windermere - there was a local guy named Ken Gamble, who was famous for his 'out of the normal' model boats.....

He once (must have been in the very early 90ies of the last century) showed a catamaran pontoon boat with one or two nice English ladies on board, the captain an English gentleman and the steam engine was a smaller version of this 3-cylinder you are talking about. It all looked a bit like a converted 'water bicycle'.

I also had a hard time figuring out the reversing mechanism, but then I saw that he had made a finely hidden flexible tube (covered with a blackened cord, so it first looked solid), thus turning the reversing mechanism into the right position.

It was the star of that years steam event and rightfully received a price!

I am very happy that you and the owner of 'modelengines.info' are now building and reviving this cutie!

Kind regards, Edward

Hi Edward, nice to hear from you.

I've now got 'Mk II' up & running. This one is very much thanks to you Malcolm.

First, I built your regulator, using a bit of round bar. I used a spring to press the selector disc against the bottom half. As you will see from the 'youtube' clip, it works well.

Then, I finally got around to your suggestion, that packing one jaw of the chuck enabled off-centre drilling, and successfully produced a two-gallery valve shaft.  Went ahead and completed this one, avoiding most of the mistakes I made first time around.

Here is the result:

The shot of the pressure gauge is blurred, but it's reading 30 p.s.i.

I've drawn up a paddle wheel and plan on rigging up a couple of water baths so that I can test it under load, before proceeding to build the ship!

Watch this space!

             

I like it a lot. On my to do list. 
When I finally finish the Duke. Geoff

Thanks Geoff. I'm very new to this, but who doesn't like compliments anyway !

If it wasn't for Malcolm's input, I don't think it would have happened.

Ray.

Really nice Ray. Beautiful slow running. It will be interesting to see how it goes under load. What size paddles are you intending to use?
Malcolm

Based paddles on 'Neuchatel' with simplifications. I've drawn them up at 227mm outside diameter, floats are 35mm deep, 75mm wide.

Bore is 9mm, crank throw (stroke?) is 59mm.

Am I being too optimistic?

I haven't actually cut any metal yet, plan to start tomorrow, so I'd be glad of expert opinion.

For steam plant, I've acquired a 12" length of 3" diameter 1/8" thick copper tube, and am hoping my lady wife is going buy me (my birthday at end of month) a Propane gun & hose for a biggish propane cylinder. If I make the boiler 6" long will that produce enough steam do you think?

It really is all guess work, plus on-line reading. I've downloaded the two boiler making files from Paddleducks and am looking forward to that.

Ray.
