    May's Brexit Plan

    Hello all, I think there is some confusion here between Europe and the European Union, which is not a country at all but a ruling body over all member countries. Run by selected not elected people who wish to subvert all national aims of their members. The whole purpose of the European Union is control and not trade as we were told originally by Heath and endorsed with Wilson's referendum in 1975. It is proving to be very difficult to extract ourselves from this dictatorial body and will, no doubt take many years before we can start to really make headway again. We need a better class of politician if we are to make the most of our opportunities, as they have been out of practice for forty years or so as rubber stamp weilders of legislature. To compound it they seem to not only have passed into law the directives but gold plated them making them even worse. A classic example is the Climate Change Act, a law that is so detructive to the U.K. and yet all but 5 M.P.s voted for it. Alec

    Audi emissions group action

    Hello Paul, forgetting the very small amount of hydro, imagine two scenarios, no evs and evs. The grid load will be x with no evs and x + ev's , renewable genration cannot respond to load, you get what you get. With the + evs that extra load will be provided by more fossil fuel generation, in effect evs are fossil fuel powered. This is unlikely to change for decades and begs the question why are we expending large of amounts of money promoting them and adding extra infrastructure.

    Audi emissions group action

    Hello Nick, those will be relatively small given the total amount of electricity generated over the life of the station. Alec

    Audi emissions group action

    Hello Paul, was this research carri dout in France where most of their power is nuclear. In the U.K. electric cars will be fuelled by fossil fuelled generation which will alter the picture dramatically. Alec

    Differential pinion height

    Hello all, does anyone have the correct pinion setting height for a 3.45:1 saloon diferential. The workshop manual does not give this figure seimply detailing the setting tool which I do not have.. my Jaguar workshop manual gives this as 2.625" for a H4 Salisbury axle but I'm nor sure if the Triumph is the same because of differing ratios. Any advice or information as to where I can find the data? I can measure the existing pinion but would rather be able to double check to ensure the correct setting. Thanks. Alec

    Brake fluid cock-up

    Hello Paul, Auto Mec sell their brand of of DOT 5. Alec

    Brake fluid cock-up

    Hello Nick, I'm no chemist so I heeded his advice? He did sort out the problem I had though. Incidentally I don't think the addition of methanol stops some people :-) Alec

    Brake fluid cock-up

    Paul, I had cause to speak to a Girling engineer about a problem, and flushing came up an I said the same " I know that the proper job is to empty the system, flush it with meths, " and his response was on no account use meths on brake systems as it is mineral oil based and will damage the seals. so I didn't. The silicone i use from Automec says on the package that it will mix with dot 4 type fluids but any advantage will be lost. Alec

    Home Power Generating

    Hello Mattius, the modular nuclear reactors gain on initial cost, or so it's claimed as they can be mass produced. The longer term down side is the staffing levels of say ten small plants versus one large plant. I can see their running costs being much higher? Incidentally, I worked at Trawsfynydd nuclear plant many years ago, long since shut down. Alec

    Home Power Generating

    Hello Motv8id, The Tesla battery (100 Megawatts) in South Australia state is good publicity but as a total answer to South Ausrtralia's many problems it is not. What is little publicised in the media is that South Australia has also bought 500 Megawatt of diesel generator back up. The battery will discharge completely in little over an hour, the diesels will provide, typically about 90% of capacity forever and a day. My interpratation is that the battery bridges the time lapse between the detection of a power shortfall and the diesels getting started and going online. Solar plus battery for grid independence, I'm sceptical but it depends on the loction? It certainly is a total non starter in the U.K, solar output now is pretty dismal. One factor that has upset the cost equation is the increased cost of grid supplied power simply due to the burden of renewable generation costs. Alec

    Camshaft Bearings

    Hello Roger, I have a Lister HR6 generator, but your one at 850 sounds wrong. For 50 Hz you should be at 750 rpm, assuming a four pole pair generator? Alec

    My weekend so far

    Hello Nick, another Daimler V8 was the 4.5 litre version of the 2.5 fitted to the Daimler Majestic Major saloon. Despite it's size it was very quick for it's day. I think William Lyons killed it off as it was a better and faster car than the Jaguar Mk 10. Alec

    Extra Thrust

    Hello Doug, sideways force will try and bend the two claming studs, it is the weakest part of the journal as far as resisting force. From a machining point of view you need to be very accurate as to the depth otherwise the new bearing will take all the thrust or none at all until the bearings wear to an equal plane. I overhauled my fairly hard driven 2.5 engine recently and although the big ends and mains showed signs of wear and were replaced, the thrusts were good to go again. This is at about 45,000 miles, oil pressure was still very good. Alec

    Extra Thrust

    Hello Doug, have you thought that putting thrust bearings on the cap puts a force on the cap which it is not designed for? The cap is very strong in a vertical plane but less so horizontally.. As a matter of interest, the Jaguar XK engine also uses exactly the same thrust bearing arrangement, i.e. halve bearings in the block only. I believe there is a good resaon to just fit halves as the cost to the manufacturer is only one pair of bearings, hardly worth saving? Yes, cast iron machines very easily but you get black from it due to the large amount of carbon in it. Alec

    Sheet Metal Nibblers?

    Hello Tony, using Duck Oil or WD40 also helps as it prevent clogging of the blade, always a problem with aluminium. I also use a portable tct portable circular saw for full sheets, especially useful if cutting thicker sheets. Alec
