Thank you for that Mike, thank you for highlighting the link address.

Its specifically the 9.5 - 10mm variety, my usual commercial supplier is over in the USA.

Really I was just asking about....... in case someone had some gathering dust or whatever..... and might want to sell them. as well as it being quite urgent.....

I  think from experience they are the best tool for the specific job in hand..... lifting sections of floor from a broad bedding plane, without causing further development along possible hairline fractures in the equally broad roof above....

Richard.

Thank you Mike and Damo.

I've got some now. arriving within a week from America,  my previous supplier and amazingly good price....

Next job is to get along the tight bedding plane..... without haste... due to following the two parallel joints in the roof.......

We've done the dye testing...... no positive results to any of the risings within a mile radius. looks like its going all the distance to the main resurgence for the area...

Now we have reached the place where one can clearly hear what sounds like the river / master cave

Very excited.
