    UFO Caught On Tape!

    Walker St Clair

    You wont be able to tow with the Walker St Clair cover, they baloon much like a parachute. Personally I use a tonneau cover to keep the inside dry but I think SBFS might do a cover that is suitable for towing with.

    Smokey's JW4 Formula Four Rebuild Thread

    The final job of the day as the light faded was to fit the battery isolator switch. I also made a short teather for the key using a length of brake cable and a coupke of crimp terminals so it wouldn't go missing.

    Smokey's JW4 Formula Four Rebuild Thread

    The next job was to make the driveshafts. The JW4's used shafts and hubs of Johnny Walker's own design, however the Carburol Special ran an uprated design for hillclimbing with the uprights machined for BMC Mini stub axles and shafts. Unfortunately the shafts were missing from the boxes of spares I'd acquired so I would need to make some new ones. Starting with a par of standard mini driveshafts the length needed was measured and then cut to length. I happened to have a pair of driveshaft spiders that I'd had claser cut for the first car but the centre hole was too small so I opened this up to the required diameter on the lathe. Mounted back on the car to check the length and now just the welding to complete.

    Smokey's JW4 Formula Four Rebuild Thread

    A few more small jobs completed today.... The first job was the manual control for the mechanical fuel pump. Like most F4 cars of the period the JW4 ran a mechancial fuel pump which was driven off a cam on the back axle. These as you'd expect would work fine when the car was moving but when the car is stationary and therefore the axle not turning there needed to be another way of getting the fuel to the engine. The Pathe videos showed the mechanics frantically priming the pump by hand but as I studied the photos and videos a bit closer many drivers also employed another method so the pump could be controlled from the drivers seat. the solution they used was very simple which was a bicycle brake leaver mounted below the dash and cable linked to the pump.

    Interior / exterior projections

    Or buy a pack of baloons and inflate them to the right diameter

    4" diameter ball floats are available from all good plumbers merchants for less than a fiver.

    V5 doc and sellin a car

    You can tax the car with the v5 document reference. you can also drive home from the MoT having passed without having to buy tax for that journey as the legislation allows you to drive to and from a pre-booked MoT.

    V5 doc and sellin a car

    Yes and Yes Between certain hours you can notify the owner change online https://www.gov.uk/sold-bought-vehicle but at other times it would need to be done the old fasioned way. The new keeper can tax the car on-line immediately with the document reference on the new keeper slip.

    2019 Speed Series Regulations

    I read that as yes unless its written into our own series regs to permit the use of something smaller

    2019 Speed Series Regulations

    It most certainly is! i think section S 7.1.3. Would apply here "Cars conpeting in hill climbs and sprints must comply with Technical Regulations 10-15 and section J." if you're suggesting that this section of the blue book doesn't apply to sprints then nether will anything that has already been quoted by others about seats as that's also in exactly the same section of the book

    2019 Speed Series Regulations

    If the MSA rules are going to be applied so rigorously this year with regard to seats and headlights, can I assume that regulation 5.14.4 will be equally enforced within the speed series and we will all therefore have to change our headlights to 6" diameter?

    Spot the Difference – Bodywork

    The flange on the nose is certainly a different shape and I wouldn't be surprised if there are differences in the width or profile of the curve. The kit wide nose is more closely matched in its dimensions to the narrow nose.

    Smokey's JW4 Formula Four Rebuild Thread

    Hi Bob, its been a while, I hope you're keeping well. the firewall on your car was a very elegent solution which I like a lot, thank you for the photos. for our UK racing regulations the firewall needs to provide a complete seal between the driver and engine compartment to create a barrier against fuel spillage or fire. On this car the body is from the JW4 Mk2 so lacks the air ducts that were fitted to Mk3 body on your JW4 and my blue car. The rear engine cover on the mk2 is much lower than the Mk3 so the cylinder head of the engine sits in the airstream for cooling rather than enclosed within the bodywork. my hope is that a simple flat aluminium closing plate will be sufficent behind the seats cut to match the curve of the body, but I may need to get creative with carboard first to get the shape right.
