Technical Matters - (Index)

This is the index for a series of pages on the technical aspects of the digging at Home Close Hole.   Because there has been quite a lot of technical geboggery associated with this dig, it seemed a good idea to write some of it up and also gather it together in one heap.   So if you don't like this sort of thing, you can link off now.   BUT IF YOU DO, then it is all together here to be savoured and enjoyed.
