A little late to the thread, but thank you for producing some recorded data on the topic! I’ve seen the Fischer 8mm (10mm with threads) x 70mm pull tested and the modern hangers broke first which was very reassuring. Consequently, now all my exploration is on screws so I can remove them and re...

I have been trying to resist jumping the gun on this matter so all I will say on this point is please read my election statement for Secretary when the Agenda is published (alongside everyone else’s obviously). It echos and emphasises the key points you make above. However, adding documents to...

I’m a big fan of triple action carabiners - owning a variety of dmm and petzl crabs - for my hand jammer and descender. I don’t like screwgates too much having had battles with things staying screwed onto places I don’t want them. For cowstails if I only caved on personal trips I’d stick with...

So I went to Poachers & OHA yesterday (with low expectations of much caving). While I was expecting very high water I thought it might be worth reporting my findings in case it’s helpful to anyone. Attached below is the recent water levels at Rhydymywn. So the river was flowing and lapping...

Having been in a fair bit recently all the expansion bolts are fine and some of the spits with the hangers still in didn’t look awful. Hangers are in place for all bolts on Pete’s topo and for Baggy’s (360 Outdoors’) alternative route. Anyway saw some cavers outside Ben’s bunkhouse this...

Just an absolute guess here that I have low hope for - Ogof Ffynnon Taff?

It certainly should!

The NMRS Ingleton Coalfield by B. Bond & Gill is a very interesting read on that topic. Looking at the elevation limestone is unlikely and this is reinforced to me of being similar to the Ingleborough Yoredale series. The peat tile theory would be reinforced if a nearby obviously manmade change...

I grew up in the Dales so did a fair few trips with Overground Underground festival as a young teenager, but really fell down the well of it as a student in Bangor where I actually did more mines than anything else to begin with - the industrial history part helped seal the deal me and I still...

It looks like your spring has gone - I'd definitely do what Pete has said above. If it were a foot jammer I'd say have a tinker but since it's not it certainly needs replacing if something isn't blocking the toothed cam's recoil.

There’s some great answers above so what I’d suggest is deciding where in the UK you want to go for it! The Yorkshire Dales and Mendip hills have been suggested so far, but you can also go to South Wales and the Peak District! There’s many great providers (both commercial and caving clubs &...

The bubble grows when it disappears but tends not to be gone completely. The theory of a reversible reaction so far makes the most sense Thanks pwhole! That should help me repair them

Two of the compasses side by side. The top one had the white stuff in it until earlier this week and its disappeared again. The bubble size has also grown again with no signs of leakage. Nope, these compasses have never been higher than 500m. That would have been my first thought having gone...

It could be. The odd part is the white stuff seems to come and go. In one of them it’s completely disappeared but I know in a weeks time it will return again

While that works for experienced cavers, teaching people about the ins and out of the local geology for every trip isn't a very robust solution :)

Yeah we have done, but it's still annoying it's happened

Silva Field 1-2-3. I believe is the model. Basically small and cheap but it’s odd it’s happened when they’ve not been damaged

Hello! Bangor Student Caving Club are having a problem where the compasses we have in our emergency kit (occasionally helpful when a little lost) keep getting this weird white mold or fungus type thing growing inside the fluid in them. This in turn eventually creates the world's largest compass...

I don't believe it has been sold and I'm yet to hear from anyone who is a stakeholder in it currently that it has changed hands. If you're really curious I would recommend buying the title deed from the land registry for £1 to check

Not part of the CRTT team but if it were as safe as Go Below in Cwmorthin then it would loose some of its charm. Wearing gloves and being prepared to break is definitely the best way to manage it. If you grab the cable behind you gently to lose some speed with a gloved hand it’s just fine in my...
