    'Caving Memories' / 'Wilky' DVD - anyone recognise this?

    Thanks for the replies. Please share the link with anyone who may be interested. From the meta-data, the DVD-R itself was created on 7th March 2013.

    'Caving Memories' / 'Wilky' DVD - anyone recognise this?

    I've found a DVD in with our club (Fylde MC) surveys and things. It appears to be a homemade DVD-R with a printed label. 44mins of photo slideshow with background music, no spoken description. There is a Lancaster University Student's Union minibus in it. Does anyone recognise it or the people...

    Humidity levels in a library?

    You may already be aware, but if you are considering the cost of running the dehumidifier, compressor-based units are better for habitable temperatures (18-20degC). If the average temperature is generally lower (~10degC) the heat pump efficiency drops right off and you are better with a...

    On't scrounge for a skateboard

    Can't help with the skateboard, but if your experiment works we've had great service from these people. We build lots of different kinds of custom trucks for getting materials & glass in and waste out of delicate buildings. They have all sorts of different castor materials and load rating etc...

    Aids for descending overhung ledges...?

    That looks pretty horrible and loose. abseiling for climbing, I’ve tried turning sideways and just let my left hip rub against the rock. That’s for sharp clean overhangs through, with the rope more vertical. In those circumstances you can just bounce/jump past it if you’re confident. Rescue...

    Caving Memes

    Or raise serious issues in a relatively light hearted way and potentially make folks question their current thinking without immediately jumping to a negative defensive reaction. If it doesn’t make the subject laugh then it’s failed, I agree on that.

    Well that didn’t take very long. Yes.

    Cost of cylinder testing?

    Last twinset I had hydro+o2 clean was £160 at capernwray. That was a mistake not asking for a price first. £320 for two sets / 4 cylinders! Previous years I’ve used scuba workshop uk near Rochdale. Twinset was about £65, £35 for singles 02 clean.

    Sleets Gill

    This is good stuff. I'm interested to know how the rainfall data knows how much rain fell in each grid square in unit time? They look like 1x1km squares so presumably there's no physical on site monitoring at this scale. If it's radar, how much actual data is in it, or is it a smoothing...

    Club trips

    I should add that we did have some problems initially with WhatsApp for forward planning, as described by pwhole above. This has vastly improved this year now we have put some structure to it. Ours now works like this : We have a master group (a WhatsApp 'Community') that all club members...

    Club trips

    The FMC is a climbing club but we do go caving. We have a WhatsApp group of regulars and potentials. Someone posts up that they want to go caving and suggests a day, people respond, we figure out where we’re going based on who wants to come. We try to be efficient with cars. The fylde guys...
