What a lovely little model Bernard.  What is the propulsion system?  How big is it and where on earth did you fit the electronics bits in?

Another very nicely weathered model as well.  I'm looking forward to a shot on the water of it.

Just Google Pop Pop model boats - dozens of references and explanations. I think somebody even wrote a book about them once.

Hi,

A very good link- the only problem being that the repeated boiling and cooling down of the 'motor' coil could result in fracture from a) The soft soldered joints or b) unlikely, but K&N metals are SO thin that it could also fracture.

Best workmanship would be to get a 4" X 2" X 1/6" peice of brass- available in K&N metals selection- make the hull the same shape but first silver solder a continuous length of copper pipe no more that 5/32" OD through the bottom of the hull with a coil as shown, first cutting the brass section to your required shape- when this job is done you can soft solder some tinplate sections to the top of the brass section to make the hull sides.

POP-POP boats work, for those that don't know, in quite a fascinating way- the candle first of all boils the water in the coil- this flashes to steam and pushes the water out at quite high velocity, but on reaching the bottom of the boat it condenses bacjk to water very quickly- creating a decent enough vacuum to pull water back into the coil- where it boils again and the process keeps on going as long as the candle burns- some POP-POP boats use a diphragm instead of a coil that 'breathes' with the flash and 'sucks' with the vacuum thereby increasing the effect- and these type make a FANTASTIC noise- kind of like a 1920's IC engine but without the smoke- everyone should have a POP-POP boat!!!!

Hi Bernhard,

That boiler is wonderful- you know with not having a proper firebox you could rig up some sort of smoke generator in the boiler too to make it look extra genuine... O0

Great thread,... I was trying to make one of these the other week for my nephew...
The heat sort of got out of hand...  %)

I will probably make another attempt when I get time. It's neat to see other versions and
other peoples constructions.   :-)

Hi Bernhard, once again you have pushed the boat out {-) with your ingenuity and style, so I have been thinking why don't you invite us all over to your place
for a weekend of steam and good entertainment and then give us all a Masterclass in person to show us all hows it's done and where you get all your little
scale items from in the form of a Masterclass Factsheet :-))

I am sure it would go down really well, however you may not have enough room for us all so we will continue to read your contributions as they post. :-))

Well done again.
Rosyth
