Carlswark Dynamite series.

[AndyF]

Fair enough, I hadnt heard of the double skinned ones....

...if we could get a length it would be an easy job  Ithink.

 

[SamT]

Hughie might be able to get you a price, but otherwise - I'd keep you eyes peeled as you drive around. You never know eh. Infact - I think terry worthington mentioned the other night that there was a load of roadworks nr Matlock coming to and end - and there was stacks of the stuff kicking about, might be worth having a word with someone down there, its the type of stuff where there'll undoubtedly be a few lengths or off cuts left over at the end of a job. Needs to be the big stuff though - to cater for the larger caver

Dont worry about the big stuff, if they cant get through it they aint going anywhere once they are inside anyway

 

[bubba]

Yes, Dynamite is pretty tight if you're biggish build. I used to go there back in the day when i was a skinny lad and had no problems, but when i went back a couple of years ago I got stuck coming back out of the first squeeze which scared the crap out of me

 

[Pipster]

Giz a shout if you want some help re-excavating. 

 

[Hughie]

I'll sniff out some prices from a couple of suppliers.

Have seen largish cavers free dive through the 600mm version, so I'll enquire about that sort of size. There should be some upcoming work on the Levels near me, so, as Sam says, there may be some spare bits around.

That'll probably be at the by-pass near the new Sainsburys (at Cawdor Quarry).

 

[SamT]

600 mm sounds about right.

Im trying to find a picture of the stuff on the net. I reckon a company called Naylor Drainage are the guys that manufacture it but their website is "under construction" no pun inteded Im sure. - I know (from googling) that Naylor Ducting, do all the stuff that the highways agency use to lay cables in (purple/yellow/green etc  ~150mm).

Reckon it'll be really costly to buy - espcially in non bulk. but If you can befreind a bod at some roadworks - it might be the best way

 

[SamT]

knew I'd get there in the end.

Whoever makes it might have sub-standard rejects that they would be glad to get rid of? I have heard of concrete pipe sections being passed on to cavers in similar circmstances. As long as those who use them accept the risk that they might not do the job intended.

At work we've just (as in on thrusday!) discontinued development of our 630mm butt-fusion machine similar to this...

...so i've been investigating the test cutt-offs of pipe. However if you've ever seen a polyethylene pipe 630mm in diameter you'll know that the walls are v thick (~10% dia) meaning that they are VERY expensive and very heavy! Will let you know if i get any oportunities, but don't hold out!

 

[SamT]

Rob - like the big yellow gas pipe thats been laying all over sheff for the last few years. Indeed - very very heavy.

This Rigid pipe stuff is feather weight - two people can carry a 3m length with one hand each.

Cuts very well "wiv a chainsaw" - bit untidy buy good enough for our uses.
If you're desperate I think we still have a stock of (chainsawed) 2m lenths of blue 630mm HP watermain stuff (if it's not been nicked).
But you'd probably have to fetch if from Astbury (Cheshire).

Listening to "Darkest Hour" as you posted Sam?

 

[Hughie]

Ok - got some prices.

6m lengths of 600mm will cost in the region of ?280 to ?300 + vat.

 

[SamT]

thought so - I'll stick to keeping my eyes peeled.

Nige - it was more bevis and butthead. a

Have strong recolletion of 'em headbanging on the sofa to Darkest Hour, but having looked at the B&B website, the only Megadeth track they did it to was Symphony of Destruction.
What the *%!^ was i doing on Fri nights! 
Miles off topic, but the pipe offers still there!

 

[SamT]

Ah - didn't spot the megadeath ref.

have to admit that I've got other priorities that flower pot. however it seems there is some interest, so maybe AndyF or Pipster might take up your offer.

Cheers Nigel.

 

[Pipster]

hmmm, sadly I don't know where to begin on such things; but theres only one way to learn and I'm happy through some time and effort at it. If anyone decides to go ahead, send us a PM, and I'd be happy to help.
