Solo. Roz was going to join me but more pressing matters put an end to that.
At the end drilled 6no. holes plus a shorter one for the trimmings. The aim is to give some more height and width concentrated on the left-hand side of the fissure. I couldn’t resist a little peek along the fissure using a beamed light rather than a diffuse one, it does look very enticing. Just a bit more work to get there is required.
Laid out the wire and everything sounded good, ready for a return on Thursday evening to move the debris and continue with the expansion works.
