  1. A few years ago, they found demolition charges under the runway at HMS Daedalus.

     

    From Wikipedia: "In April/May 2006, whilst conducting repairs to the runway, building crews discovered an unexploded pipe bomb, of over 60 feet long, placed underneath the runway by the military, designed to cripple the airfield's operational capabilities in the event of a German invasion. The bomb (along with 19 others subsequently discovered) was scheduled to be removed in September 2006. The work was completed on 24 October 2006."

    It makes you wonder what could be left at other former airfield sites. :shake:

     

    When I lived in Martlesham Heath, rumour had it that there were two of these under the old runway, and only one was found when they demolished it and built the housing estate. Waiting for the bang during any building works became a local past-time.

  2. The loss of so many rare and unusual vehciles is traggic.

     

     

    Buildings cost a lot of money to build & operate so it's simply not possible for most museums to get everything under cover. I doubt any of the museums mentionned in this thread would have intentionally left exhibits to rust away, but without the facilities you simply have to rely on enough manpower and funds to keep renovating and preserving over and over again. In this way you keep refreshing regularly enough that serious problems won't have a chance to develop.

     

    I would imagine in these cases, a critical problem occurred between refreshes without warning, or other factors prevented them being swapped or sold before they went beyond salvage. No museum would intentionally waste money, effort or exhibits, as all are extremely limited resources.

  3. There are two competing factors for museums. Preserving the vehicle means keeping as much original as possible, and marking any replacements to ensure that they can be told apart in the future. In this way the exhibits can be preserved, but this normally means non-runners, as the original parts are precious and preserved from wear and tear, although the vehicle is left (as far as possible) in running condition.

     

    Other vehicles are preserved in working condition to show the human impact of those vehicles. You only get a sense of perspective from the human act of witnessing the vehicles in action. In this way the experiences are preserved, and the other static exhibits are put into context.

     

    You can't really do both, as wear and tear / maintenance has an impact on vehicles.

  4. But Churchill wasn't a cruiser tank, (but then again neither was Centurion, Cheftain, Challenger)

     

     

    Centurion was a heavy cruiser that was redesignated an MBT, and marks the point that the naming convention moved to MBTs.

  5. Here are the pictures of the offending sockets.

    That one has some useful linformation on it - It's a Bendix made connector (now part of Amphenol, who are the name in a lot of the military style circular connectors) 2822 probably relates to this insert. I would have thought if you send Amphenol support a copy of the pic they would identify the connector, and it's probably available through the likes of digi-key.

    Looking at this website -

     

    http://www.aecsinc.com/Catalog1.pdf

     

    MIL-DTL-5015 has a 2822 insert.

     

    and http://www.amphenol-aerospace.com/catalogs/12-025/lo/12-025.pdf

     

    shows a 28-22 type in the AC range :)

  6. Commando sockets normally run a 16, 32, or 72 Amps

     

    Lauren, no such thing as a 72 amp commando socket. The next size up from 32 is 63 amps.

    The correct name for these plugs is Ceeform, Commando are ceeform sockets made by the electrical manufacturer MK.

    Sorry for being such a pedant. :rolleyes:

     

     

    No worries, and thanks for the update - I dont work with anything over 32 normally :)

  7. You may find that the round pin connectors are "Commando" EN 60309 connectors, which are normally standard wiring etc. Those are normally associated with high current electrics (like you would see on a generator connection). Depending on the gender of these connectors you should be able to work out if it is supply or outlet.

     

    I would majorly recommend against using the BS1363 UK plug for supply - Aside from the obvious danger using the male plug for supply (i.e. you can touch live conductors), aircon etc. may require substantially more than 13 amps to run.

     

    Commando sockets normally run a 16, 32, or 72 Amps depending on size. The colour normally indicates voltage (blue for 240V, red for 415V, yellow for 110V). Theyre pretty easy to find as they're used a lot in industry, and are pretty easy to wire in (or get wired in).

     

     

    BS EN 60309 here -

    Also it could be a military style connector, like

  8. Not sure if anyone else is stuck at home with Flu, but if you are there looks to be a bit of a "Military Motors" marathon on this afternoon from 3 - 7. Theres two episodes of something else mixed in with 6 episodes of Military Motors.

     

    Of course, knowing how these listings work it may be two episodes repeated 3 times, but I live in hope :)

  9. Just a side note - I had a similar sounding (though luckily not so infected) nasty bite on my arm that took *ages* to heal properly. What did it for me was the Elastoplast silver-weave plasters. Itched like the blazes but it did the trick. It's left a scar but at least I don't have a hole in my arm anymore. They may do you some good as well.

     

    Hope you get well soon!

  10. Second vote for the needle guns in preference. Loud and hard work, but definitely better. Sandblast the small unboltable/detachable bits and needlegun the hull and big beefy bits. The small bits should fit in a sandblasting cabinet that will keep the grit from going everywhere.

  11. Silly question (from me): Is the load carrying weight of the 15cwt, not 15cwt?

     

     

    Yes, The load carrying weight of the C8 GS 15 cwt is indeed 15 cwt.

     

    I'm wondering what the load carrying weight of the C8/P is? Is it the same as the C8 GS?
