Following Markus's brilliant idea for a smoke generator (see "Smoke" topic in "Markus's Radio Control Corner"), I am doing the same but fixing it so that I can change the generator without having to dismantle everything. The generator is a Seuthe 491 and the whole range of Seuthe smoke generators is available in the UK at DCC Supplies (www.dccsupplies.com) and Sharp Models (www.mgsharp.com). This is how I intend to fit it:  I will drill 2 holes in the deck structure where the funnel fits so that the 2 screws slot into them and can be secured underneath (possibly with some silicon grease - as used in the rudder and prop tubes - under the funnel to make a watertight seal to the deck). |

Dear JC
I ordered from DCC Supplies. The smoke generator (Seuthe 491 - plus 50 ml bottle of smoke oil) is £21.54p (includes VAT), the 250 ml bottle of smoke oil is £12.37p and post/package is about £3. Doing a search around, the DCC price is about the lowest

The funnel can obviously be made up ready and smoking as soon as you receive the funnel parts. Fitting it on the boat will depend when you think the deck structure is ready to receive it (e.g. depending on decking, painting, etc.). Anyway, here in the UK we are only up to part 83 and the funnel bits don't arrive until parts 107/8, so I still have about 6 months to wait !!!

That's a great job Jack !! Now for a bit of fanciful discussion.
Smoke generators never produce truely realistic looking smoke, and I think there are two reasons. Firstly, smoke doesn't scale, same as water, which is why the bow wave and wake never look quite right. Not much we can do about that.
However, the second reason is the velocity of the smoke. It just drifts out from a smoke generator, but on a real ship it is blasted out with quite a force. Do you reckon it would be possible to fit a fan to increase the velocity of the smoke ? Perhaps using a low volume high pressure fan (like an electric car tyre pump ?) and a blast pipe, similar arrangement to the funnel of a steam loco ?

Or how about a fan unit out of an old laptop/pc or would that be too powerful? Not sure about size either may have to shoe horn one into the hull.

I found this on ebay at £3.99 (about 5 euro)
A 6V, superb quality cooling fan, by Micronel Ltd of Switzerland. Axial in style with a diam of 23mm and a length of 30mm the fan assy is housed in a sturdy cylinder with a square front mounting plate, with four hole fixings (22mm centres). Micronel pt no D244L-006GK-1.
An internet search also identified a goodly number of 6 volt fans but this one seems a very good shape. This is small enough to mount under the deck below the funnel. Probably best to take a small plastic tube, push it on to a small plastic funnel (the type used to fill perfume bottles and hip-flasks) with the mouth of the funnel over the end of the fan. Then take the tube up through the deck and into the back end of the funnel, about half way up (probably best to use a 3/16 copper tube with a right-angle bend to stick the bent end into a hole drilled in the back of the funnel).
However, I won't be doing this as you can see from the video (see my build site) that the smoke is reasonably dispersed through the various holes in the cap and when I gently blew over the top, to simulate the boat moving in the water, it looked quite good.

popeye. Just found this page. smoke looks very good. Never used it before so interested. In fact I think I shall fit it but I have a question from the drawing.
The stainless rods in the fluid do they require a sleeve on them to stop short between pos and neg?

The oil doesn't conduct electricity, so no worries about it shorting out.
