Good day,
I'll continue here the simple build log of my first steam project. Here are the previous posts about this with some pics: http://www.modelboatmayhem.co.uk/forum/index.php?topic=14917.0
Christiaan will get brass propeller with diameter of 65mm, 4 blades and 4 mm shaft. The kit had 3 bladed and slightly smaller in diameter made from white metal.
I'm not going to make engine mount, nor propsaft mount my self. I have a friend who has tools and experience to make these in such a great quality that I'm always tempted to use his services instead of making these parts my self. I know that I should make it my self but I'm always finding good excuses not to.
So Regner and hull is at the moment at my friends workshop. After I'll get it back I'll post pics with this projekt first time on the water.

Hi,
Engine and rudder mounted. Test run succesful. Maybe during weekend I'll put her on water.

More pics.

very tidy! thanks for the pictures.

You will prob find with that type of regulator that it will turn through 360 deg if so you can just move it 90deg from where it is and it will work there , no need for extension. they have four holes in the colum and two semi circles on the operating disc so moving it around is no problem.

Very tidy set up there with a neatly put together plant and shaft.
Just one word of caution, if you haven't already done so I would file a flat on the rudder stock for the cap head screw to land on. There is a lot more chance of it slipping if you don't take this precaution.

Hi,
Thanks to you all for very usefull advise!!
I'll pass the compliments to responsible person.
Have you got advice how to attach the mahogany to boiler? With bands and glue? If glue is used, what glue can take the heat?
And derekwarner_decoy: you are absolutely right! I'm learning with the best, including you guys!

I would suggest that the planks are simply placed on with spots of cyano at either end. I would ensure though that the first time you flash it up to have plenty of ventilation as the fumes may be excessive. You could also use spots of PVA or any other glue because the glue is only going to hold it in place while you put all the planks on before using brass bands to actually hold it all together.
You could also persevere with putting one band on loosely and then threading the planks into it but you will find this a lot trickier than holding the planks on temporarily with glue. Don't worry about the glue resisting the heat because when the brass bands are on the glue isn't actually doing anything any more.
-
you can also use the thin cellotape type double sided tape, the narrow stuff thats about 6mm , again as Bunkerbarge has stated its just to hold it until the bands are put on.

If you can it would help if you wrapped the boiler in the ceramic matting then planked it.

I have attached the wood strips only with metal bands to 2 boilers and they are holding fine. I wouldn't use any glues as they will scorch and make a mess, stain the boiler etc.
However it is easier to work with the wooden strips if you use 2-3 rubber band to temporarily hold them to the boiler, then after you have all strips in place lock them down with the metal bands.

and you have seen this happen , boilers staining due to a few spots of glue ???take it from someone who has been doing steam a long time it wont stain, it is also the recommended way Cheddar did all there boilers, but what did they know.

Depends on what glue you are using, and if you care about the aspect of the boiler below the wooden cladding.
Since I have spent quite some time polishing my boiler, I chose not to use anything that sticks to it or stains it. But this might not be important to everyone.
-
Many thanks to all! No I have plenty of methods to choose from!

Hello,
Still not yet had change to get her on the water.
I have finished the main deck frames on which the deck is resting (see pictures). Also heat insulation is in place on the hull and under main deck (1st picuture).
Superstructures and main deck mahogany is next under work and balancing the boat to waterline with led around the bilge.
I bought some round windows to hull from aero-naut. Window glass already fitted in frames. Great quality.
I though that I'll put one set of batteries for Navigation lights and other possible gadgets, and another for receiver/servos.

Hi,
jollyroger is writing in Finnish. free translation: that's really great, nearly done, just mount main deck and waiting for the summer.

Hi,
First time on the water. Here some video: http://www.youtube.com/watch?v=f-DXj210mxw
and http://www.youtube.com/watch?v=b3mhkz8lcHE
And pics. Everything vent well. Engine run as usual. I put some two kg of lead to get her balanced.
Next phases will be mahogany planks to main deck, painting the hull, building skylets, mounting windows to hull and superstucture etc. etc...
BR,

IlCapitano...... O0 her manoeuvrability seems great :-)) Derek
-
Thanks, thats right!
I was surprised to see her maneuver that well. During filming I had to adjust the servos. Propably one can hear beep from my radio...
I did not have more than 2,3bars on the boiler so there is more in reserve.
all in all there were no setbacks at all during seatrials.
Yet there is still ALOT to do to complete this model.
have a nice weekend!

Hi,
Some pics before and after painting.
I'll varnish it with ackryl mat to get the shine of a little. Now it looks too "plastic".

Hi,
Boiler has been lagged.
Is it recommended to coat lagging with something? (Varnish, oil...??)
-
You need to protect the wood from staining by water and oil as well as preventing it drying out and warping with the heat. I would put a couple of coats of Polyeurethane varnish on it. I would also do the planks individually and ensure that both sides are done so I would varnish the planks before fitting them.
-
I personly would think twice before painting the back of the planks with anything as they will direct on to the boiler and it will burn off and leave a mess also only put a thin coats of Finnish on the boiler and watch how much you put on , if you ever look at an older boiler you will see how it can go like toffee if its to thick wood will very lightly char on the back and will then not burn, you would not put polyurethane on a boiler as a coating, putting it on the back's of the planks is the same
thats my view anyway
Proteus
-
Then perhaps you could suggest an alternative?
-
Then perhaps you could suggest an alternative?
?
I just have don't put anything on the back and just a thin coat on the planks, does your boiler planks have the backs painted with polyurethane ???
Proteus
-
Are you saying that polyeurethane is OK on the surface? Your message could be read as you don't use polyeurethane at all, in which case what would be the alternative?
-
Yes it is not a problem on the surface, but as I said I keep it to light coats, so as not to get it built up to thick . as I also said it is the way I do it and I tried to give the reason's why. if you look at the temperature range of polyurethane it will not take a lot of heat.
I am going to try some Danish oil on the face of the planks on the next boiler I do, as this can be re coated with a cloth and rubbed off , but as I have not tried it yet I would not recommend it, it needs to be tried over a season's running, boilers that are run in the open do not seem to suffer as much as ones that are enclosed in the likes of tugs

ilcapitano........this issue has been discussed O0 & resolved on Paddleducks,,,,,,,,,,with the general consensus to add a layer of refractory material under the planking
K-O-WOOL 1/16" thick sheet was an option as were various thin layers of woven glass mesh sheeting....which I have added to my boiler build .....
We also discussed various surface treatments for the planking with the conclusion that 'oils' may be the preferred option......Derek
-
Sounds good thanks Proteus.
-
Oiling the planks worked well for me. Needs to be done at least twice.
-
Hi,
Many thanks! I used woven glass mesh.

Hi,
Planks oiled with water based teak oil twice.
Hull is now painted and varnished.
Paint is two component polyurethane acrylic paint. And varnish as well. Now it should last "from father to son" ok2
Finish is propaply not as mat as I hoped, but good enough for me.
Name was also given. She is now "Anni" after my daughter.

Hello,
main deck planking is done. Waiting to be varnished.
Portholes finished.

Hi,
It takes some 15 minutes for boiler to reach 2 bars (faster of course when I pre heat the water before filling the boiler). Running time 20 minutes at least. It seems that butane runs out before water, which is great of course.
S.S. Anni was the only steam powered boat at the Model Expo. She got alot of attention.
I quickly built condesator from old glass medicin bottle and now exhaust steam outlet is from funnel. I have to built better as soon as I get some spare time.
I'll shoot some longer videos as soon as ice melts from lakes.

Is that the exhausted steam that seems to come out the side of the boat in the second video?
-
Hi,
Yes thats right, but now I have modified it so that steam is coming out of the funnel.

Nice, but there's no steam visible. Did you route the exhaust through the stack?
-
Hi kno3,
Yes it is routed throuhg the stack. Wind takes it away well and it is not "steming" alot unless put full ahead.

Not seeing steam is GOOD, as it means the steam is nice and hot, superheater is working. Only in an inefficient engine / boiler do you see the exhaust steam. O0

could any learned gentleman or lady answer please.....was it the real Christian Brunnings that was used to great effect in the film of the book "Riddle of the Sands" starring Simon ward and (god the brains stopped working and I've forgotten)
