    Discussion on the bling ferret

    It was so well fixed no-one wanted to buy it for a long time as most of us were watching it - and when someone did it was sold it below what it was worth.

    Does that include putting back the bits that have gone missing ? (If you can find them)........ Diana

    Discussion on the bling ferret

    It would have cost as much to de-bling it as put it back to the way it should have been - a message to blingers there 🙂 Also known as turning something into scrap!

    We've had the bling Ferret, and look what happened to that! Is this the bling CVRT? Diana

    6 or 12v jeep?

    So Tony- given the foregoing, An AC current generates a magnetic field across the wire that opposes the flow of current, known as induction. DC does not. and expounding your vast knowledge electricity can you explain how a DC clamp meter works? Diana PS - I did study physics, I think your ideas on electricity are wonderful 🙂 . I am in awe, as I'm sure is Chris McMillan.

    6 or 12v jeep?

    It would be phenomenal, I am surprised this idea hasn't caught on by now. And think of the saving in natural resources, all based on hollow cables 🙂

    6 or 12v jeep?

    I see.. interesting, a bit like water going down the plughole. the swirling is different depending in which hemisphere you live. I must ask the next electrician I see if I can have hollow cables as the inside bit isn't any good and I am paying for it 🙂 Diana

    "Basic rule AC runs ON a wire, so surface area is important, DC runs IN " So the skin effect operates at 50Hz does it???? Diana

    Wanted to Borrow Muddy supports

    You do realise that stainless steel and aluminium are not compatible,? Mixing them in direct contact on a cvrt is likely to result in corrosion of the aluminium. Diana

    CVRT throttle lock - stupid idea?

    The wingnut is essential if the engine is started from a cold start, charging a battery or using the boiling vessel to boil, or warm water. The habit is to make sure it's backed off. Diana

    Blocking up Vehicles.

    In a local garage I was astonished to see a car raised each corner on 4 trolley jacks ! Diana
  12. NOW SOLD Owing to having no time and too many things on the go, for sale is a Gas gun firing control circuit. with the two valves, spark plug, and coil. I'm also throwing in a spare coil. All this complete with instructions. £55 postage paid. This is unused and untried but the instructions are complete. The circuit is set up for a Browning heavy machine gun, but can easily be adjusted for other gun types. You will need to construct the barrel, swirl chamber, fit jets, provide the gas and tubing - all info is with the instructions. PM me if interested. Please note I will not send the instructions without the parts i.e The complete package needs to be bought. Diana

    Anneal a diesel pipe

    Well if a copper pipe breaks because it hardened yes

    Anneal a diesel pipe

    You have the wrong type of pipe, it should be copper nickel (Kunifer). Kuniper is used for exactly the reason that it does not harden like copper. Suggest you replace it with the correct pipe, some rubbers will not tolerate diesel. Diana

    JAGUAR J60 CARB, cold start

    The thickness is 0.3 mm. who the seller on eBay was I cannot remember. Sorry you'll have to do a bit of groundwork, it was around 6 or 8"" square, more than enough to make a few diaphragms. I suspect this will be too thin for fuel pumps as they are under considerable pressure and duty cycle. Diana
  16. I am looking for a pressure plate for a Churchill Tank. Please send me a private message if you have or know of one. Thank You Diana

    JAGUAR J60 CARB, cold start

    There are three diaphragms, if you have the correct material (off eBay), some patience and a hole punch pliers they can be easily made, by copying the originals, at a huge saving in cost. Diana
  18. Chris, Absolutely correct, I have designed and built the interface box for the warning pod over the UK nearside indicator - that works too and shows the battery not charging. Diana
  19. On my Spartan when the engine/gearbox is cold there is quite a bang on switch off - alarming but normal. Get it all warmed up and the bang goes. When the engine is running normally the warning light on the distribution panel comes on and the ignition light on the drivers panel goes off. Diana

    CVRT track re-rubbering?

    Cooks have the moulds to manufacture track where the pads can be replaced, but they have never implemented it and I'm told never will.. Diana

    CVRT electronic ignition question

    The J60 may or may not have points, some Belgian machines have points. If The J60 has got an electronic ignition module then it will also have a rev limiter built into the module that can be disabled by pulling a fuse which will either be on a fuse holder incorporated into the ignition coil (British Machines) or if a Belgian machine on a fuse holder adjacent to the coil. The Rev counter is normally driven by a pickup mounted on the counter through which passes the ignition feed wire. The Rev counter was made by Smiths Industries and is now unobtainable, through age it loses accuracy and can also lose linearity. because of loss of magnetism and the hairsprings becoming weak, as well as friction through wear in the movement bearings. It maybe repairable, in the end I gave up with mine and fitted a VDO rev counter with a sensor off the fan, The VDO rev counter also has a hours run meter. The diesel model CVRT uses the same VDO rev counter using a Honeywell sensor mounted on the flywheel sensing the flywheel starter teeth. A suitable sensor pickup point on the petrol engine is also the flywheel starter teeth, were in not for inaccessibility a more ideal sensor pickup point would be the rear of the engine crank toothed belt drive which has less teeth per revolution. Anyone doing a conversion to a VDO stepping motor rev counter needs to consider the design of the sensor and it's maximum pulse output, since with too many teeth on the pickup point some sensors cannot cope with the frequency. Some sensors require power and others do not. The other considerations are the clearance between the sensor and the tooth or bolt head it senses as well as the cost of the sensor (The VDO magnetic sensor is astronomical in price) The VDO stepping motor rev counter is the most versatile of rev counters, will cope with most types of sensor and can be calibrated in situ.

    The Works - Books

    In the Works bookshop yesterday - Haynes Owners Workshops manuals reduced from £22 to £6. I saw The Tiger, Sherman and Chieftain. There may have been others. Diana

    ws19 to variometer coax cable

    Television down lead is 75 Ohms and near enough to 80 Ohms that it can be used and you will see no difference whatsoever at the frequencies used by a WS19 Diana

    Umm Yes :-)

    Who's going out in the snow then?

    Depends on the vehicle....
