I have a vague recollection of a discussion on here a number of years ago about drilling gritstone cobbles but a quick search hasn't turned up anything. Anyway is there a conclusion about the best drill bits or is it just a case of burning through cheap bits?

Just that really, photography and surveying is becoming a bit of a pain having to put on and take off reading glasses, not to mention carrying them around. Are there any alternatives? Had anyone tried a monocle :LOL:

I guess some people on here may have hired a car in Bilbao in the last 12 months. Any recommendations? What to avoid? Happy to pay a fair price and not get stung for damages rather than going for the cheapest option.

This popped up on my tubes - what could possibly go wrong? If nothing else watch from 21 minutes, but then watch all of it

I've got some Meindl leather walking boots, they must be about 10 years old, but they are in reasonable condition apart from the leather has cracked on the side and they now leak. There are products available called "leather fillers" does anyone have experience of these, would a leather filler...

I'm posting this on behalf of Fulk who, for some reason, can no longer log on to UK C: 'The rainbow’s' upside down.'

My El Speleo Gnoma light has more or less packed up, it still sort of works but is not ideal. It's not that old but apparently parts are not available for it (I've been in touch with the manufacturer) which is a shame because it was a good light. So I now have a good quality lamp housing with...

Asking on behalf of a friend: Does anybody know of a Chinese caving organisation please? I have a student who wants to join a club in his local area but can only find commercial organisations that want to take his money. He is potentially a good caver and lives in Chongqing area which has a...

Out for a walk on Saturday and noticed this at 54.1765861 N  ,  -2.0413616 W on Cam Head. Looks like it is in the Grassington Grit but there is some limestone evident and looking at the BGS Geology viewer it's not too far above limestone. Someone might want to have a poke about. Also makes me...

I'm sure we have all wondered about helectites in caves, how about helectite icicles?

I can see this turning into another hideous CRoW debate and I think we can all agree that we don't need another of those so please, it isn't a CRoW debate! Many clubs have websites and publish photos from which people can be recognised so they are likely to be deemed personal data under data...

More of an idle musing than a serious issue I think (hope) but something I came across at work today got me thinking about fretting fatigue and karabiners. In my experience most cavers used steel maillons up until relatively recently when the trend has been towards alloy karabiners. It seems to...

Does anybody know what Red Moss is like in the wet? I was thinking of having a trip there on Saturday but the forecast is looking a bit damp.
