It has only taken about six years , but we finally set up a syphon to drain the passage at the start of the dig .
We should now be able to dig all year round with the minimum amount of faff.
Next week should see some real progress , and my first view of the air gap was very encouraging .
We will need to turn slightly left into the middle of the passage , but there is a definate way on now .
