  1. Soda is very expensive and will not touch your 432s.

     

    Either use Iron Silicate or Calcium Silicate or alternatively try recycled glass.

     

    Both are available in bulk (and it is much cheaper by the ton). We like the former as it created less dust, but the glass is very good for delicate work. Unless your work is really really rusty the medium grade of either is ideal. Try googling scangrit

     

    With all due respect to the previous poster I think blasting with sand is pretty dangerous - and it is in fact banned.

  2. We pulled in for some fuel on the way to pick up some stuff and when I got back in the cab the old ERF electrics were dead as a Dodo...

     

    I called Autohome and gave them the details of where I was then wandered over to the garage shop to grab a coffee while I waited. As I walked back to the truck a chap appeared. "Are you the truck that's broken down?" he said. Having informed him that I was, I went to show him the problem (Autohome had tasked the workshop behind the garage...) and of course when I jumped in the cab and turned the key the old Cummins burst into life.

     

    I congratulated the chap who was grinning like a loon on his magical abilities and we left - and everything has been perfect since!

     

    So technically I have used them and they were efficient and in this case quick. I particularly like the fact that they will get a big truck off a busy motorway in quick time - thereby avoiding compulsory tow-offs which can run into thousands. The will also come out and change a wheel provided you are carrying a serviceable spare.

  3. In 1985 the "standard" of paint finish on your average GS landrover was - er - average and probably applied with a brush straight from a very large can of paint IRR spraying/brushing black and green. It was only later (much later) that all that sort of thing was frowned upon and contracted out to specialists.

     

    The SOP for instance, for repainting tank transporter trailer decks was to tip about 20 ltrs of brake fluid on the deck and spread it out with a bass broom. Once all the paint had peeled it could be scraped off with a GS shovel and disposed of (environmentally obviously - it was Germany after all). It was then replaced with green or black (depending on what the QM was giving away that week) applied (probably) with the same bass brush....

     

    When spraying took place it was usually done using airlines from the trucks, and the only nod to any damaging physiological effects was the issue of 1/2 litre of milk to those involved in the spraying.

     

    Anyway to the matter in hand - I am sure that there will be plenty of folk who can help you out! Good luck!

  4. The current police advice is to use a dual-band SBD (secured by design) type as the simple ones can be jammed by a GPS/GSM blocking device.

     

    I use Smartwater on all my tools and so-on - they claim a 100% conviction rate.

  5. Good point on the coverage - and getting the tank clean to start with is important too.

     

    Although you can get a decent cleaner it is a bit pricey so I use milkstone remover (available from your local agricultural merchant - they use it for cleaning milking equipment). I have also heard of folks strapping the tank to something like a cement mixer, putting a load of nuts and bolts (count them in and count them out) and spinning it about to knock off any loose bits inside before applying the liquid.

     

    As long as you stick to the amounts recommended depending on the size of the tank and keep moving it about the coverage will be fine.

  6. I seem to recall a test ages and ages ago of classic cars and the only engine that appeared to fare badly from just unleaded was the O series BLMC engine. Mind you that engine was made of monkey metal to begin with.

     

    That said the car fraternity are wedded to either valve seat inserts or fuel additives; strange really when my sons US spec (ie unleaded) MGB cylinder head is exactly the same as the UK equivalent.

     

    So whilst popping magic pebbles in the tank may not do any harm I remain utterly unconvinced that they do any good either - especially as a replacement for lead and that the average user would be much better served by regular maintenance, sympathetic driving style and decent engine oil and coolant.

     

    On the subject of ethanol there appear to be two worries. the first relates to plastic and rubber components, and there seems to be some substance to these concerns with a number of outlets offering "ethanol proof" pump valves diaphragms and so on. Certainly one to watch as time goes on. The second and in my view more important issue is the hygroscopic qualities of the ethanol, allowing water to become part of the mix with obvious effects in terms of internal corrosion.

     

    The advice seems to be either to keep tanks of irregularly used machinery either as full as possible (thus eliminating damp air in the tank above the fuel) or as empty as possible, minimising the amount of fuel there to absorb moisture in the first place.

     

    My guess though is that in half a dozen years time this will all seem a bit of a non-issue and we will still all be driving our old motors around perfectly happily.

  7. I run all my old engines on standard unleaded. They only do a low mileages at relatively low engine speeds and I fully expect them to be chugging along happily while I am having an interview without coffee with my maker. I am sure that some engines are better than others but the ones we are concerned with I think will run happily on standard unleaded.

     

    Out of interest has anyone, anywhere, experienced significant valve seat recession as a result of running on modern fuels? If so what were the engines and the circumstances?

  8. Although I cannot find definitive proof of it I am sure that pool petrol did contain lead even though the octane rating was very low (72).

     

    Lead was used from the mid 1920s to improve the octane rating (not to improve the longevity of engines) although other fuel manufacturers added different things at least to begin with.

     

     

    Pool petrol remained the only game in town until the mid 1950s

  9. Once upon a time Antwerp Bks (where those photos were taken) was the home of 3 Tank Transporter Squadron, and that square was full of Antars!

     

    In fact not far from there are the last remains of a set of overhead traffic lights from the road out of Soest ....
