    Ribblehead to Hawes road closures

    I suspect that the works might require multiple closures at different places along the length and at dates which are not accurately predictable. Therefore a traffic order has been made to legally close the whole length over the 5 month period, saving a lot of paperwork and legal costs, while the...

    Incoporated Clubs

    Craven Pothole Club is a Registered Society, a relatively new corporate form. I think Bradford PC may also be one.

    No, it has very imaginative name of "Prince Charles's Cave"

    Steel vs aluminium scaff tubes

    Aluminium alloy corrodes less than steel, but some caves may have more aggressive condition. I took a brand new shiny krab down F'ing Hopeless and it came out looking 10 years old.

    Tick prevalence in the UK

    Typical government scheme, all they're interested in is getting a tick in the box.

    New book on Ogof Ffynnon Ddu

    No criticism of Tony intended, but I think his order management software doesn't understand about back-orders - I seem to remember it sent me an email saying my stuff was shipped but it actually meaning that processing the order was complete.

    A question about the gym

    The torque has to be greater to accelerate it up the ramp, but once it's moving it only needs to match gravity. The hypothetical car had a control mechanism to regulate its speed that doesn't produce heat.

    A question about the gym

    That's true. But on the other hand, the friction force between the tyres and the treadmill is the same as between the tyres and the ramp. So the torque required from the engine is the same, and the rpm is the same, so the energy expended by the car is the same. But on the treadmill, that...

    A formation in Simpson's Pot

    Voices, by Geoffrey Summerfield? Copies available on eBay and online used bookstores but haven't found a scanned copy.

    A question about the gym

    Yes. It's a parallel situation and provides me with another way of thinking about it. When you prusik up a pitch, you gain potential energy (mgh). When you abseil that pitch, you lose exactly the same amount, and it turns into heat in your descender. So if somebody lowers a rope, with your...

    Wrist watches for caving

    Very easy if you have a small Phillips screwdriver. There are two screws each side, in line with where the sprung pin would be if there was one. PS - but probably impossible if you don't have a suitable screwdriver
