I have posted this on HMEM but thought that some of you may not visit the site so here it is:
Steam all over the place due to poor connections but it runs on steam so I am pleased.
Now need to sort out the safety valve and those connections and test again. :)

Thanks for the positive comments.
I had little choice but to make the boiler after the one I purchased on E bay was soft soldered :bang:
It is a multi tube design with 53 tubes.

Very nice engine and looks like it will be a good runner. Thanks for posting it. :ddb: :ddb:
Cheers :beer:

very nice
compressed air is ok but you can not get the same burns lol :D :D :D :D

Fantastic job! I would have sworn that was a kit. Very nice indeed.

Really nice engine, Is it your own design?
Steve

Not my design but my first build it is in fact the Borderer designed by J P Bertinat, Reeves supply the castings although I made my engine from stoke material.
-
Now with improved regulator
-
I have started to add all the bits to a steel plate ready for insulation into steam launch the engine now has a water pump added:
-
Steam plant starting to come together now lots of pipework completed still lots to do.
-
Now running as a steam plant not finished but pleased so far.
I think I might have to play about with the burner perhaps.
-
Gorgeous! :clap: :thumbup:

This is the steam engine in the boat as you can see I need to clear out the pond ::).
Does anybody have experience of making water tanks any advice would be welcome?

Nice boat Mark. :thumbup:
Water tanks to go inside the boat or a tank big enough to run the boat in?
If you mean one to carry water in for the steam engine then I would use a fuel tank from the model airplane hobby.
You could also make one out of a piece of brass tubing or copper tubing.

Placed the plant in the launch and tried it out pleased with the result so far.
Issues to be resolved include:
cooling of Gas tank
location of water tank
Using condensate to warm gas perhaps
make a some more fixtures and fittings

Very nice mcr. Can't wait to see it in the water under it's own power.
I'm working one getting one fired up that my dad built. I'll have to take some vids when I get her running.

I have now connected the engine to the prop shaft will try it in the pond tomorrow weather dependent.
I have had to remove the water feed pump as it was geared down too much so was not filling the boiler quickly enough.
Something to do as the weather cuts in.

:bugeye: stunning mcr :bow: :bow: :bow: :bow:
Hope we get to see a vid of here on the water :poke:

Very nice she's sitting in a very nice boat as well can't wait to she her on the water.

question ? why do u need a water tank ? why could u not just have the tube for the pump inlet just stick though the bottom of the boat and get its water from what ever the boat is floating in.? nice boat by the way i really like it a lot. very pretty boat
-
Very nice. Just watched all the videos again.

Crabsign,
The water is just not pure enough to use, even though it might look like perfectly clear water, it will be full of suspended solids, and even though they can be filtered out, some will get thru and build up a deposit in the boiler, plus when you sail in different areas, you don't know whether the local water is hard or soft. Unlike full sized steam plants, these small ones really do need to be looked after correctly, otherwise small orifices and supply lines can get blocked up.
I was lucky with my steam engined boats, I live in a very soft water area, so could use just normal tap water, without the risk of scale build up, but normally, people buy distilled water or collect rainwater (correctly filtered of course) for running their engines on.
MCR,
That is a wonderful installation and hull you have there, it brings back lots of memories for me. If looked after, you have a model that will steam for a lifetime.

Thanks for all the positive comments it means a great deal from your peers.

Fitted with new feed pump

Mcr,
One thing you shouldn't do with such a small boiler is to feed too much water, as you can soon overwhealm the burner and so the boiler starts to cool down, with obvious results.
The boiler you have should give you about 20 to 25 minutes steaming, what you should aim for is to extend that steaming time to say 40 to 45 mins before the boiler reaches say 1/4 full. By that time, you will most probably need to top up the lubricator and give the engine an external lube and a rest.
When we used to sail our steam boats, we found that we didn't need to go any longer than a normal fill of 20 mins, as we were ready for a rest, chinwag, cup of coffee and a smoke break. Four or five sailings on a sunny afternoon we found just perfect, and maybe only two in the winter.
Just enjoy.

With the help of the little sketch you posted I am aiming to extend sailing time as an insurance measure rather than becoming bored sailing around in circles.

Nice sounding and running engine there MCR.

In the home straight now so I asked my son to take a few photos with his new early Christmas gift.
