    Good morning John, I will be trying to remove the jacket later today, so I'll post pictures and results later.
    As for the fuel mix, a buddy who works on helicopters at the SAS camp was helpful in this, as the motor was covered in so much crap he suggested immersing it in diesel overnight, then blow off with air line before cranking it. He suggested that as it was a diesel it should fire up on diesel with a little help from bradex easy start, but as I don't have any he said to try a few drops of methanol, 10ml of diesel and two drops of methanol from an old eye dropper. A piece of silicone pipe was fitted to the fuel line in and a small funnel, then a piece of rubber pipe push fit on drive shafts and held in battery drill. Put the fuel in funnel and opporate the drill, and away it went.
    Cheers Colin.
    Fair winds and calm waters, COLIN.

    Thought U were goin' to hit the hay a while ago John!? πŸ˜‰
    Greetings from one model fan and insomniac to anotherπŸ‘
    BTW agree with your comments about the water jacket.
    Sweat the screws out and the rest should be relatively easy.
    "In this the most perfect of all possible worlds"!
    Cheers All, Doug 😎
    BTW: TELL me about those relays! For a year or so back in the early 70s I used to service and calibrate the radiation monitors at various nuclear research / power generation sites around England. The detectors tripped a relay via appropriate drivers, which then triggered the unit Nixie tube, etc, etc.
    My job was mainly cleaning and setting the relays and doing a calibration against 'normal' background count, cosmic radiation etc.
    To reassure folks; during the whole year - year and a half I never ever saw a count above background! But then - that was 46 years ago 😲

    Re that jacket. it may be easier to shift than you think. it looks as though there are soldered over screws round the top.If you can remove them the jacket might just prise off. The exhaust stubs just unclamp.If you can get that off you may then be able to see what motor you have. I see a likeness to one of the E.D. 1:49sπŸ‘πŸ‘ P.S. Colin can you tell me the proportions of diesel and Methanol you used please ? I'd like to try it for myself. What gave you rise to think it would work? I'm really fascinated by this. Regards JohnπŸ‘πŸ€”

    And what a capacitor. Big enough to have come from a washing machine of that period. Maybe it did. The whole thing looks like a lashup. Used whatever would work.I had loads of old valves but noone wanted them so dumped them. Some of them were More modern ones to replace the DCC90 but 1/3 or less the size. Those relays look like the old G.P.O. type. We got them from a Gov't surplus shop for buttons. Those were the days. Sometimes we added in an R.A.F r/f amplifier without the case. it increased the range but don't ask me now how we wired them in. There were 4 connection points on the casing which accepted a multi-plug connector secured by a threaded ring. Nice bit of kit til we got our hands on them.😁

    Agree on the vintage value (same applies to your Supermarine actually!)
    I thought you wanted to try and get it all working.
    I see two more bottles in that perspex box. What are those?
    I'm beginning to wonder if that's the RX and the chunk with the DCC90 is the TX. The DCC90 bottle could produce 2W RF in the HF band. So 27Megs would be in for example.
    Cheers, Doug 😎

    Appreciate your help, apparently only the large capacitor and 1 of the relays is suspect. The radio magicians from camp it would be possible to replace them but it would lose its value as an exhibition piece.
    Cheers Colin.

    Thanks for the 'electricals' pics!
    Definitely a triple XXX Home brew.
    DCC90; would appear to be an RF double triode. Used as an RF amplifier and/or oscillator. Possibly in the UHF band.
    Trying to find some decent specs on it.
    If yours is dud there are still some around for a tenner or so;

    Must dig around in the cellar; somewhere I have a box of valves too!
    (Surprise surprise! I hear you sayπŸ˜‰)
    Cheers, Doug 😎
    PS Here some history and data on the bottle. Up to 40Mhz apparently.

    Bon chance mon ami!
    Your the man for that job, I never got beyond a little Enya and a COX 047 Glow job. Still have 'em somewhere.
    Was thinking of using the spare Glo plugs as ignition for firing guns or launching depth-charges on my destroyer! A little saltpetre, charcoal, eye of newt, wing of bat, 2V on the glo plug and ..... 😁 bye bye destroyer probably😲 Cheers, Doug 😎
    Now back to me cutter gearbox, ya know I think it might actually work!!
