Hi Goydenman, any idea how much you want? Tom

I've just posted an opportunity under using conveyer belt Tom

Hi everyone, I was invited to Hansons' quarry today and met a super helpful guy called Asif. The Man! So here is the plan. 1. There's a mountain of belting. 2. They are paranoid of H&S etc with understandable reason. 3. We have a collection date for you explorers, Saturday 18th May this year. Ok...

I was super proud of my long red bar from Roughneck, a monster at over a meter, until I bent the begger trying to lever out a chunk of an erratic boulder from a sink at Greenhow. Now it twists and turns on a pry and is only any good for stabbing boulder chokes then running swiftly away......

There is a way to calculate inclination using the depths at successive survey stations. My surveyor buddy has coded it to be useable in a Therion environment. I'm not a diver but he once was. It's in an early stage but we are confident it will be useable. I guess you are aware of this but the...

Set out a caving route made of chairs with lots of twists and turns. Chuck in a few with low brace bars here and there. Divide into 2 teams. One team sits on the chairs. Give the other team torches and switch off the lights. Time them through the course. If someone can't get through they submit...

New name suggestion. Council of the Northern Caving Community. Aka CNCC. Hoping you like it Tom

Hello, Hanson's Quarry at Greenhow, Pateley Bridge, York's, are demolishing their old plant soon, moving the processing plant across to the far side of the quarry. They have kindly agreed to set aside some conveyer belt for our CPC dig team at Stump Cross. Would any of you like some? It might...

Hi everyone, thank you very much for the information, it's all appreciated and I've since looked at lots and lots of 12v and 24v options, pond circulation, caravan pumps, sewage pumps, as a former sailor, bilge pumps and all. Still not convinced by these for a variety of reasons. Spent today...

I'll take a look. It's often the case that internet searches are all about the key words. I'll add pond pump and take a look! Cheers, Tom.

Hi Royfellows, Have you come across any that cope with big dirty water? I found lots of these 12 v items, but they were all really small bore? Thanks though!

Thanks Chris, yes I guess some straightforward maths will help. I was expecting the RPM to be an issue. Might need a drill gearbox as well! The pumps are on site (Stump Cross ) at the mo, I'm going to pick one up on Wednesday and take it home to play with. They are typically about 500w. I found...

Hi all, I was wondering if anyone had attempted this? I / we have a couple of 240 v submersible pumps and I was considering building a Frankenstein version. I converted an ancient Hilti battery drill, (batts dead and no replacement option) to run on a 36v ebike battery. It's 20 amp hour and it's...

Hi, I've just posted this on the surveying page: Hi all, on the distoxble subject, Alan and I have been trialling the development work that Siwei Tian, (xble PCB developer) and Rich Smith (SexyTopo) have been collaborating on. We are hugely grateful to them for this effort which is restoring ST...

Hi all, on the distoxble subject, Alan and I have been trialling the development work that Siwei Tian, (xble PCB developer) and Rich Smith (SexyTopo) have been collaborating on. We are hugely grateful to them for this effort which is restoring ST to the new Disto platform. Beta 5 version is...

Ha ha Alastair, Andrew yes, we do talk survey on the dig, everyone else looks dazed and confused, what on earth are they on about!? But we also share lots of ideas on our own WhatsApp confab, also meeting up to survey on our so- called "Inbetweeners", and on a pre- die test recently, (...

Hi Benfool, Thank you, I am on the non- playstore version, aware of the discontinuance issue. I think we have Vs 2.7 from memory but will check your link. I suspect my ignorance of TD is the main culprit. I'm mostly posting to find out if anyone has any specifics learned on working with the...

Hi Alastair, thanks for that eye opener. So l need to click that download arrow, I guess I did randomly in the hope it would achieve something, hence getting a few splays and 2 stations. I may have inadvertently opened ST in all the to and fro, but more likely there is something going on in...

Hello, is anyone else using the X310 device with the PCB from Siwei Tian? We have had a couple of goes and struggled to maintain connection to the tablet. This may of course be cos I'm hopeless on Topodroid which seems to contain landmines in its ability to control the instrument. For example...
