Yes, both are registered as registered societies which is one of a number of different types of mutual societies (such as co-ops). This group along with those who chose the company route, usually as a limited company, are corporate bodies which the law recognises as a distinct 'body' thus giving...

Thanks mikem. THE WELSH MINES PRESERVATION TRUST does look different from the Welsh Mines Society judging by the web sites and linked addresses. So that makes 17 so far. I was hoping individual members of clubs who were incorporated might respond as well but your efforts are much appreciated.

Many thanks to mikem for what I susect was a computer aided analysis and for the other comments, especially martinr observation on charitable status. Of the clubs listed by BCA, I total 8 as incorporated so far.

The topic of becoming an incorporated club has just been raised within a club I belong to, the primary reason cited being to minimise the risk of being sued to the trustees. I note there are some 150 plus clubs listed by the BCA as member clubs. It caused me to wonder how many clubs had taken...

My wife and I picked up ticks on Mull and in Assynt, Scotland in the past couple of weeks. Repeated body scans seems to be the only solution. I wrote the attached for BCA some while ago but it got lost off the BCA web site.

The Labour Party manifesto last year included a commitment to publish a white paper on "access to nature". I wonder what may transpire.

I gather the cap end is taken as the datum point from which length and angular measurements are made. If so, I don't need to attach it to a tripod but can just locate the end on the tripod top to give me a usable station at a handy height.

Can you mount it on a tripod? (I am planning to do a surface survey linking a number of cave entrances.)

Has any one any information about an opening in the east bank of the River Spodden at NGR SD 8810 1653, just north of Healey Dell near Rochdale? I saw it yesterday when on a geology walk; the speculation being that it was a sough for a coal mine into the lower Pennine Coal Measures. I've not...

I would suggest trying the Mendip Cave Registry . There is even a map allowing you to focus on an area of interest. Though I accept not a guide book.

A fair number of years ago I reported some research done on the strength of SRT ropes subject to different usages (one use being one abseil down and one prussic up). The results showed a substantial loss of strength as measured by the number of drops taken to break a sample. I also tested one...

I just copied the text. Have just checked and yes it is spelt with an extra i. Since it was saying "any other maps, such as ordinance survey maps, are irrelevant" I would expect the bit "such as ordinance survey maps" is irrelevent. So just read it as "any other maps are irrelevant".

This application amused me as I recall and have now found a statement by the Welsh Government / NRW in the 2020 judicial review, the DETAILED GROUNDS OF DEFENCE OF THE WELSH MINISTERS. That stated at paragraph 64: "The Welsh Ministers have no firm position as to whether caves fall within s.1(2)...

BCA used to offer a service of drop testing used SRT rope. The problem with that service was that it did not comply with the test specifications of the standard for SRT rope. So although it showed used rope did degrade, the result from it was of no use in comparing with the requirement of the...

I went for varifocals which allow me to read albeit for a short while before my eyes get tired and I have to switch to my reading glasses. But possibly that won't work for fine bits on a camera screen. However, I think the range of varifocals is proportional to price. How about a hand lens...

I guess that I should add that we are well aware of the impact of a squidgy body as well as beams not being stiff enough on reducing peak forces. What I was originally after was a feel for what steel work might make a reasonably rigid structure for dynamic work, which is what Steve's...

Access to a drop test rig would help us side step these considerations and hopefully conclude our work on peak forces involved in falling on cows tails. Any offers would be welcomed. (We could even use a 1 tonne lifting beam provided it had the head room.)

Sorry to disappoint you Ian, but Steve answered my question albeit using a static approach. Simply put and quoting their blurb, it is a freeware program providing "tools to produce, export and edit solid, full-precision models, export them for 3D printing or CNC machining, create 2D drawings and...

PM sent

Has anyone experience with FreeCAD or similar program capable of undertaking a FEM analysis? I would like to get an idea of how a simple structure (a tetrahedron) could withstand a sizeable force slung from an apex. Please PM me if you do have the knowledge.
