LATEST SMOKE PULSER FOR GUNS ETC
As a follow-on to Grahams' comment on our latest collaboration on a smoke pulsing 'capacitor driven' device, we thought it was time to 'chuck it out there' and see what you think. I saw the vid on the guys warship with the very fancy gun smoke system a while ago and thought there must be a simpler way than the sophisticated and technical way he did it.

Having done press setting in my early days, I remembered that a big press we used to set had a hydraulic capacitor which helped get the ram moving (pretty much what electrical capacitors do for motors etc) I started with a common party balloon with no container and knew Graham would be interested, and it progressed from there. As usual, Graham has done a fancy bit of electronic control on his, with solenoid and timing and has it working nicely.
(just received my new solenoid which I will be adding in due course)

Balloon is stopped from filling by a micro switch to the air pump and air is released by solenoid at whatever timing you need (depending on how well your smoker can keep up). If the system has no leaks, the 'capacitor' can hold air indefinitely, ready for use, and will re-fill automatically, (pump only runs to re-fill) This idea can be modified to suit anything (guns, exhaust startup and run, steam to simulate steam whistle etc) Balloons of all shapes can be used eg -(long thin sausage balloons could be fitted inside a tube if space is an issue).

With a good air pump, the 'capacitor' will fill quite quickly and some good pressure can be achieved.

    Always thinking of improvements and new gadgets Martin, which might be useful for new model builds. At least Graham and I have got it pretty much sorted, so people can do modifications to suit their particular models. Main thing is that these devices are cheap and simple to make (in basic form) which is the whole idea, and can give your model that little bit extra. Most bits can be easily sourced from Ali Express/ Ebay etc.

    Hi Jb,
    "these devices are cheap and simple to make (in basic form) which is the whole idea".

    I fully agree thanks to you and Graham and your fantastic experiment.

HI everybody

Another ebay purchase, a Fire Tender which I think is from the 50's. it is fitted with a very unusual old motor with sprung loaded brushes, capacitors, and a fan.... seems to run happily on 12v, which I plan to reinstall. Does anybody recognise it? it was fitted with a 'spring' universal joint. I am fitting a conventional UJ. There is also a circular switch attached to the motor. This appears to be wired to switch in up to 3 battery supplies! but I think I will fit a modern controller with modern nicads.

I sail at the Maldon and Blackwater Model Boat Club at Heybridge.
Regards Frank Burgess

    HI

    Yes it is...I scratch built it using a GRP 'workboat' hull as a base. I used a simple drawing from the 'Jolie Brise' book blown up to size. I altered the bow, stern and the keel to match the drawing. The rig is slightly undersize and simple the keel is deeper, the deck layout is very approximate taken from photos but simplified to make it more robust for sailing. it has a winch for sail control and the rudder is controlled from the tiller via lines and blocks to a servo under the cabin top.

    As you probably know the boat was bought as a Le Havre Pilot boat by EG Martin who then instigated the Fasnet Race, which Jolie Brise won 3 times.

    Thanks for recognising it.....best regards Frank

    HI Frank I have built model of jolie brise from plans I got from France made few years ago as static model, I have made uo a false keel that I can fit as and when I get round to making sails, have provision for steering via chords running thro the deck in tubes to the steering servo, as yet no thought as to how to install sail winch as have only small openings where hatches fit. you are right about her being pilot cutter and winning fastnet 3 times, she was however built by Monsieur Paumelle in 1913, I hope at some time to get her on the water.
    Regards Chiffs
