Hi Allan thanks for sharing your very interesting build and culminating into a beautiful model we are sure you are very proud of ,also of great interest for me is the yarrow boiler and perhaps I have missed some aspects of the boiler build would you mind letting me know what sizes of tube and piping plus the overall size
Cheers

Hi John
The boiler is straight out of KN Harris boiler book. page 166
I can't post a picture due to copyright but the book is freely available, just type it in google.
The only mod I made was the steam take of, don't use the tube make an outlet at the top.


The size will depend on what you are planning to put it in.
I would suggest that you make it as big as you can as I've had to modify mine quite a few times to get it to hold steam.


Hope this helps

Thanks for the prompt reply Mike can you tell me what modifications you made to hold steam and what pressure can it maintain with the engine running as I intend to replace the boiler in my 5ft long ferry which has a similar spec to the tvra graham engine

O.k. John
It holds about 90 p.s.i. which is about 80 p.s.i. more than the engine needs.
The mods I've made are to put a water coil inside the engine and as much heat as you can fit.
You can just see the coils in the background.
The burner was made for me by ooyah/2 (George) and is about 4" long and about 1" wide.
but as I say the bigger the better, you can always turn it down!
cheers, Alan

Ha Ha Ha Martin you stole my thunder
Just to explain, the guys is the 3d department of our wonderful website drew the cormorant for me that goes under the bow spit

I got a friend in Dubai to print it for me so fitted it quickly for the show
I had the pictures to put up when yours cam through
But a great Job done by all and I think it looks great
Did you notice the beak was broken !!! one of the helpers pinched it against the mast so a repair job already.
One of the 3d guys has actually printed the bird on his machine at home so maybe no need for a spare
Thanks again to the 3d guys
I've also made a mod to the boiler supply valve.
I've moved it from the back of the boiler as it was getting too hot.
This set up is a lot better and controls lovely.


O and Martin, there is only one Alaska but thank you for filming the club display, the members where chuffed.

Hi Alan,
I saw the vidio from Martin earlier, you model is truely magnificent and an inspiration for others to emulate.

I have recently purchased a Deans Marine Thames Launch "Helen" so over the winter I shall have a go at building my second model boat ever.
The engine, a Stuart "V" twin, has already been made so a boiler is next.
I don't know if I will have the patience to build somewhere anything like yours but hopefully it will sail and the paint doesn't run.

George.

Thank you George and what a lovely little engine
It's great that your going to make another boat, just think of all that sanding !!
No seriously it will be great.
I hope your health is going o.k.
It was such a shame that some Muppet broke the beak off the cormorant
my wife couldn't believe I was so calm about it but as I said he was 85
and did not do it on purpose, I don't think he realised he'd done it, so I didn't tell him.

Hi all and a Happy new year
I've had a rush of blood and started on the passenger seat at the front, opp's Bow !
Also found a very nice technician at the local school who made me a steering wheel.
This will be great for a template but I think I will have to try and make one, Unless there is an expert out there who can make it for me?

Hi Kerrsy what kind of steering wheel do you want, RB Models make different sizes both in wood & in brass. You have to put them together as they are a kit, not so easy to assemble but are quite nice when put together. Have a look it might be just what you are looking for. Mick B.

Hi Mick
Thank you for the info, I looked at RB models but all there stuff is too small.
The diameter of the wheel is 85mm.
But thank you any way

Beautiful!  She has a fair turn of speed as well. A real greyhound of the water.  You must be very happy with her.   :-))

Thank you Greg
Yes I was surprised how fast she was, The water tank and auto feed system worked well and still had half a tank when she ran out of gas after half an hour of steaming
The gas tank was only about half full so I could get at least an hours sailing from one fill.
I must confess to being a little emotional as of she went around the lake on her maiden voyage after lots of trials.
I have made the canopy for her but this will be for non windy days.
The pictures shows her with a paper template but the frame is made.
thanks again
Alan

Yes, great result Alan, it's been a long haul but worth it in the end , a truly beautiful model , sits well steams well.
Your little Yarrow boiler certainly produces enough steam to keep her going, I bet you have to keep that burner very low which will help immensly with steaming time.

I will phone you soon.
