    Caving with a joint replacement

    My better half has given up, as after a shoulder replacement following a cycling accident, she can't raise her arm above horizontal effectivly ruling out SRT.

    "Emergency Climbing Rope"

    After finding myself in a tricky situation on the back of Sgùrr Dearg some years ago I bought an Edelrid 'confidence rope' essentially 20m of 8mm. Whilst advertised as not suitable for blah blah blah, in an emergency I have no issues...

    Help re Rechargable 18650 Batteries

    Whilst this is generally accurate, please don't measure the length with calipers unless they are cheap plastic ones and thus insulated. Otherwise you are shorting the cell, which if it is unprotected, will result in a suprise.

    Relative knot strengths

    I know perfectly well what average means (no pun intended), I didn't waste all that time at school, uni and 25 years as a control systems engineer for nothing.. I'm pointing out the samples shown in the video do not give the results they presented. The sample size demonstrated is far to small to...

    Relative knot strengths

    Interesting video, but presumably some of the samples ended up on the cutting room floor as the numbers presented don't add up with what was shown. One of the badly dressed ropes tested stonger than a good one and the other was close. I'm sure there has been more testing elsewhere but those...

    Kingsdale bore

    I would say that is Kingsdale Beck just up from Braida Garth. Long Gill is much further up the valley, at least according to OS.

    UKcaving Free-cycle

    Looks like it uses the same battery as later marks of the model 8 Avo. Plenty of equivalents available and diy solutions.

    Far country ladder, which entrance did they go in via?

    The price I was quoted recently for galvanising was ludicrous due to the price of zinc. Probably as cheap to make in stainless. A modular design could be quite simple and easy to assemble on site. Rungs from 1/2 Schedule 80 pipe, tapped to M16 at the ends. Side rails from channel, joined with a...

    Cave Rescue Procedures (continued)

    This I find intriguing. I can't see anything illegal about looking for an overdue party. Presumably more along the lines that CRO insurance doesn't cover them until they have offically been asked to help by the Police?

    That maybe the case in Ireland but not in the UK. Change of use is required.

    Changing simple bobbins

    How helpful of them! If you've ever looked at the Loctite range of threadlockers and retaining compounds etc, you will know there are hundreds. Type medium is a bit vague to say the least. A squirt of 243 will be just fine.

    Dales Monopoly Board

    So it appears the Dales is to get it's own version of the game. https://www.bbc.co.uk/news/uk-england-york-north-yorkshire-66499379 Deadline for nominating landmarks is the 31st Aug. Do we need to push for some caving entries?

    Changing simple bobbins

    I've forgotten far to much physics but I suspect it's not that straight forwards. I should imagine specific heat capacity, bobbin mass and friction coefficients will play a factor. I would suggest they are typically aluminium due to weight, ease of machining and material cost all being...

    Rope labeling

    Personally I use wraps of coloured insulation tape as per the resisitor colour coding system with clear heatshrink over the top. No numbers to rub off, I got shot down in flames the last time I suggested it though.
