Posted: Mon Apr 25, 2011 10:32 pm Post subject: OFFICIAL WWPPBB2011 Boat Hall
As I will be away at the beginning of the official posting time and opening of the viewing hall to all-
I will start this thread with notice that no one is to post here till 12 am GMT On April 29.
All entries that wish to be considered for grand prize and class awards must include these minimums:
1. A photo of the boat
2. A video of the boat under way by it's own power.
NOTE: More elaborate pictorials are encouraged and welcomed and may include build details etc. Creative use of the camera has helped many a beauty contest winner through out the world! So help. your self all you can.
You may do an initial post and add to it as the weekend progress or open your "table" all at one go!! The choice is yours. I leave myself the luxury of delivering the final winners announcement on my birthday which is June 12.
I also may be in contact with a few "non entrants" for their opinions for additional voting to balance the ballot! _________________ Lagniappe readily offered and accepted,

Having missed out on last year’s pop pop event I finally got round to building something for this one, I must warn you that I’m terrible when it comes to building things, although I admit I quite enjoyed doing it and I’d encourage anyone to do the same and join in.
Anyway the theme for my boats was simplicity and they are made with the absolute bare minimum of materials, the hull was originally supposed to double up as the fuel holder too but I had buoyancy issues so I used a burner from one of my commercial pop pop boats. The hull is made from a tealight holder and the boiler is a simple coil type and that is all there is to it, I know it looks quite crude but it does the job.
I’ve added a few pictures of the builds below:
Pipe from 27ace27
Bent into engine
Buoyancy test with a US quarter
Seems to hold the weight of the engine ok
Boat no 2
1 & 2 together in drydock
This was my first boat and I had some copper pipe come from 27ace27 that was intended for my MM2 restoration by Moose but he had already finished it when it arrived so I put it to good use for my first boat. However I failed to angle it up and could not get a flame underneath and the pipe was too thick and heavy, but I learned a lot from that first build and my second one was a little better.
This was made to the same design as boat no1 but I used much thinner copper tubing from K&S and angled it upwards so I could actually fit a burner!. I also added more coils to the engine, I didn’t anneal either of my copper pipes and I bent them round with no problems (I guess I must have a strong grip! )
Anyway I’m pleased to report that boat 2 was a success despite it not running for very long (about 20secs a time), I had to add a bit of bluetack to keep the tubes under that water due to them sticking out when the burner was in place.
Overall it was a very enjoyable thing to do and I’m thrilled I made something that actually works!
I'll be second to not leave you all lonely.
I've built two Putt Putt boats.
The first one straight of Mogo's links.
The aluminium can, straws and milk carton one.
The first boat started its life as a nice drink.
A few snips later and I had this
Then some more cutting, folding and glueing and I was here
Then a milk carton later and some hot glue and silicon and I was done.
Did it work?
Well I think this photo says it all
But if your not convinced here is the video.
I've made a second one, but you will have to wait for that one, but here are some teasers
A few more out of sequence construction photos.
Sorry about the quality, I don't know what was going on with the camera.
Traditionally my boat would of used a tobacco tin to sit the burner in, but I don't smoke and tobacco tins are a bit of a rarity today so I had to make my own. You've seen it in the photo above, but here it is before it was bent and soldered up.
First full shot of the hull before the motor was installed
Test placing the ribbing for the underside of the hull
More to follow later
A few more photos
Ribs and engine fitted
It soon became apparent I was going to run out of time so I decided to just get the boat to running condition and will finish the rest later.
Once complete it will have a 2 (maybe 3) tone hull and the engine bay will be covered with a cabin and mast and will end up looking somewhat like a tug boat, except for the rather pointy end bow of my boat.
Here it is ready for its maiden voyage
I'm about to fill up the paddling pool and give it a test run.
First I got mail, two days ago, that the materials I ordered last week weren't available, leaving me no time to order somewhere else.
So the valved engine idea was abandoned and I started working with materials which I had lying around.
The Tommy engine. (guess how I came up with the name. )
Lots of hammering and soldering.
I silver soldered the square tubes (I didn't have any round tubes) and soft soldered the membrane.
Obviously I didn't test the boiler too well for leaks as water was leaking where the tubes entered the boiler. A quick repair with soft solder should do the job, but the membrane started leaking now and the once beautiful soldered engine ended up in a big mess.
As a last resort I decided to fold the edge to seal the top of the boiler. I hit the paper thin membrane with the hammer and that was the end of the Tommy engine.
The design was sound. Although it leaked it did work, so tomorrow I'll start all over again. _________________ Paul
Hi folks. Here's my entry for the WWPPBB – The Hamburper (spelling intentional ). It's a fairly traditional design with a single coil heated by a candle stub. Initial tests implied that it would need two candles but formal sea trials (in the bath) showed that it worked better with one. The initial tests also showed the necessity of a rudder – not to make it go round in circles but to keep it in a straight line! Without it, the poor thing was spinning randomly depending on which end of the tube “fired”.
The hull started life as a tin of ham (contents were disposed of down my gullet first), the coil was formed from a length of 4mm copper pipe, the rudder, deck and chimney from sheet aluminium. The sandpaper under the coil is to stop the candle stub moving about. The whole thing is stuck together with epoxy. If you're wondering about the lump of Blu-Tack; the superstructure caused the hull to be slightly bow heavy so I stuck some ballast in the stern using the Blu-Tack. It turned out that the Blu-Tack was sufficient on it's own.
I've provided two videos – a short one just to prove it works (and more suitable for those with slow connections) and a long one with introduction and commentary on the trials.
Paul, I have no words how jealous I am of you, you actually have forming tools. For every forming, I usually make special wooden formers.
As the event has already begun, I'll show the engine that never was as well. This was meant to be a wood-coal-what-ever-fired engine, but problems with silver soldering held me back. Nevertheless, it's a fine looking water heater or a firesheet for a boiler anyway. Yes, there are supposed to be flues through that element, which is the reason I spent two evenings marking out the honeycomb positions. Well, I'll install them someday.
And.. finally. My entry for WWPPBB 2011.
Annabell is the name this boat holds.
Unfortunately her burner also befriended the deck, which resulted in removal of the decking behind the engine. Mostly because it just burned away.
She's a runner, I even did a video, but - oh, how stupid I am - pulled the memory card out, not realizing the upload wasn't finished yet, and of course formatted the memory card.
"The boat that never left dock". Looks like I'm a candidate for that competition after all, but just that you know, she did run. I don't really care anymore, for me it's the fun of carving out a hull the traditional way and doing brasswork like no other boy I know. It would have been nice to see her pop a few circles, but I think I'll save the final tinkering to someone else. _________________ Donaudampfschiffahrtsgesellschaftskapitän !
Some more great builds, i like the hamburper Roly and it is a nice clean design and i think blu tack is the boaters friend.
I like the look of that early boiler with the firetubes Timo and sorry to hear about your memory stick issues, and Annabell is a good looking boat. _________________ My Website: http://swiftfoxsteamco.webs.com/
