Hi all

So after getting absolutely nowhere trying to get an Old Smokey smoke generator, I gave up and decided to build my own. It uses a seuthe12v super smoke generator which produces huge amounts of smoke, and I mean huge far more than I was expecting. The rest is all home made, to my own design to partially fit in my boat and also so it produced the effect I wanted.

I built a housing to mount the smoke element in out of copper sheet which also acts as a chamber for the smoke. This in turn has an outlet in the top where the funnel fits on, and also a division to make sure the air passes straight out drawing the smoke with it, (see marked line) There is then a small 40mm fan on a length of pipe connected to the smoke housing, which is connected to a speed controller and powered by its own 12v battery. The drive motor also has its own speed controller and the two are joined via a Y lead from the receiver.

So when you turn it on, smoke is produced and fills the housing and gradually fills the funnel then drifts out the top. When the boat goes forwards the fan comes on giving a nice big puff of smoke, then the faster you go the faster the fan runs in turn the faster the smoke is pushed out. When running at medium speed which you do most of the time, you get a nice plume of smoke coming out that looks far more authentic than just drifting out on its own. It was designed to simulate a worn out diesel engine, hence the big plume on start up, and the fading the fast it goes. It’s fed via a traxxas fuel tank as it tends to use quite a lot of smoke fluid.

After testing it seemed to run much better on its own separate 12v battery as when run off the main drive battery the smoke tended to slow as the drive motor drew more current. Connecting the smoke element to its own battery instantly made a huge difference.

Now just a few bits to permanently connect and its nearly done.

Maybe I can add a few tips. A friend and I have been try to put up a 100% home made smoke generator. We ended with somthing looking very much as don's great job exeption made of the independent speed controler wich is a marvelous inproovement.
Still what might be usefull to some of you; We have used a smal coil spring pensil type as a resistor, it's aplyed on a small lair of heat insolating fiber glass. using a 7.4 v 1500 mA NIMH battery. Our smoke oil is simply lamp petrol, wich gives great smoke and is very cheap. For those who try it you will find it can produce a great amount of smoke with very few petrol. Best regards to all of you, your Greek friend from the french riviera.
