    Like the sporty looking Leyland fire engine in the background.....................wonder who that belongs to :cool2:

     

    It is rather swanky looking :D. My wings are off a fire truck

     

    Hi,

    Is it a UK reg ACMAT? I set up and bought the ones in the Army! If so, can help you out a bit. Jim

     

    Mine is an old one from the Irish Army, but any info, reading material, bits and leads are always great :D. A UK one was seen over here not so long back..... was a bit of a shock

     

     

    The wings all welded together......

    The replacement red wings that we had already figured out were different than the original ones turned out to be more of a puzzle than ever expected. The original wings have a sloping rear so to keep the same lines we would chop the rear off the old ones and merge with the red ones. As you can see in the piccies there was a few more areas that needed rethinking but one side is tacked up ready to finish.

     

    It does help when the team you work with, via emails can communicate well and point out good ideas/suggestions

    The Arms have now gone away for sand-blasting – we have tried to protect the bearing surfaces as far as possible by wrapping some blue rope around them very tightly. The Ball Joints will have to come out and be replaced.

     

    Of interest that tape we use in the military for everything, airframe tape, 100mph tape (100 mph was how fasted it was nicked) is useful to protect surfaces to be sandblasted. As the texture is rubbery the grit bounces off

    It would be difficult to coat the cathode in the radiator case. However, suppose you wanted to reuse an original but very heavily pitted aluminium bottom tank. Could you clean it up, fill, and paint, and then place a small slab of zinc inside the the tank connecting it to the copper base plate. Robert

     

    Coating is never perfect, but I guess a pinhole is better than the whole thing corroding. If it has a drain plug in it you could attach a bit of zinc to it and take it out every now and again and look for wastage.

     

    It has had me intrigued since this topic came up in another thread a while back as aluminium and brass/copper is a really bad combo but who would have thought of the lifespans we are talking about. You can get some very fancy types of coatings they use offshore which they check using holiday testers. But unless you got a mate in a oil and gas paint shop its expensive. I can find out what the coatings were this guy used on his Pinz as he is based in Melbourne?

    One of the Pinzgauer experts came back with this response.

     

    "As regards your question re painting the inside of the housings, below are the reasons;

    Stops weeping/permeating through the castings.

    Helps with oil drainage.

    Seals any stray material/media after blasting etc."

    Some time ago there was some discussion on another thread about the effects of galvanic action on aluminium top and bottom radiator tanks. I was wondering whether a paint might protect the internal surfaces from severe pitting.

     

    You have to be very careful with this concept. Logic would say to paint the aluminium as it is the anodic part......... But it would be a great deal more effective if you coat the surfaces of the cathode i.e. the brass or copper bits.

     

    Ok basic corrosion we know the anode corrodes..... so my method appears odd. The bit most, even industry forget about is size matters.

     

    The bigger the cathode to a smaller anode the faster the corrosion. If you coat the aluminium and there is one tiny pinhole then you have a massive cathode and a ting anode, so corrosion will be extremely fast. If you coat the copper brass and there is a pinhole you have a tiny cathode and a massive anode so corrosion will be almost negligible.

    Drivers 'not adequately warned' over end of tax discs

    I would have to agree that a lot of people even car dealers did not know of some of this as came up in a conversation whilst I was over last trip https://uk.finance.yahoo.com/news/drivers-not-adequately-warned-over-011241813.html

     

    “Anyone buying a new car will no longer be able to benefit if there are months left on a car’s tax disc as their tax will no longer be transferred with the car, so buyers will need to renew their disc straightaway or risk facing a fine.”Paul Watters, head of roads policy at the AA, said: “Vast numbers of people could be hit, as many car sales involve someone saying ‘I’ve put tax on the car for you’.

    “That this will no longer be possible has not been well-communicated at all.” Under the new rules, car sellers must tell the Driver and Vehicle Licensing Agency (DVLA) immediately of the change of ownership, and the new owner must register to pay tax before driving the car away.

    It stuck in my head when I was reading it in the UK as most people sell a vehicle with 12months roadtax.

     

    oops forgot that the start date is 1st of October
