    What to do about v large granite rocks found in workings

    That's useful to know. Watching that rock flying off to the left made me uneasy. By chance it could have come in his direction though it didn't. Maybe better containment would be best, with him out of the vicinity & remote way to activate.

    What to do about v large granite rocks found in workings

    I'm drilling 14mm holes 4- 5" deep and using steel shim and wedge set each 3 - 4" apart to split them down to managable sizes. But there is not always a smooth even face exposed for working on, so several attempts on one rock may be necessary. It's laborious. You thinking of a specific other...

    Partially worm eaten joist ends

    Thanks. I'm going to cut them off. Thinking to blackjack (bitumen in white spirit) ends and sit on DPM base. Clearly wall has been damp though not below ground level. Know what you mean about plates and being no holes - this is not a problem here as joists sit on wall edge and there is plenty...

    Partially worm eaten joist ends

    3 old pitch pine joist ends are partially worm eaten at the sides. It's not bad and appears to be shallow only. Easiest to do is double up and bolt ons without chopping off wormed ends. Then again worm may not be dead, though my feeling is it is. Can I somehow treat in place wormed ends in...

    N2 terminal on 50A Mk dipole switch overheats

    Terminal screw was tight when I first removed wires / switch from wall. Blue N2 wire is stripped back 2 - 3 mm beyond where the grub screw bites when fully pushed in as far as it will go, so seems no blue insulator from the wire was under the grub screw. Looking carefully at the wire it seems...

    I have a squeaky stair that runs at 30 deg or so from the ground up to a balcony.
