This was a recent conversion on the excellent JJC Smoke Generator "Old Smokey"
As the basic unit has only one outlet for the steam /smoke and as the model I was fitting it in had two funnels, I had to do a bit of plumbing.
It was a case of fitting a standard T fitting to the end of the unit and 2 right angle fittings on the end of the T fitting.
Then drilling out the solid funnels and running 15mm plastic piping up through them and connecting the whole lot together.
Plastic tubing was used throughout and standard fittings from the local DIY store are ideal.
It works well when connected to the JJC Cat Turbo Diesel sound module and the speed controller.
All in a very nice piece of kit, puts the old oil burning ones to shame.
This link shows a quick video of the unit just after I fitted it.?

The model is an Mobile Model Marine Portgarth, nearly finished now as the clip was taken over a month ago.
