Repairing Nicked Extension Cords

[Toolmaker51]

I use "flexible" heat shrink tube. A week or so back I nicked a cable down to the bare wire, it was in the centre of the cable. I cut through and made staggered joins in the two lines (a no earth tool) with the heat shrink on each, then a second layer over the area where the outer sheath was missing and then a final covering extending 12mm or so over the outer sheath. I have several such repairs and never had a problem.

Skill is only part of it, supplies and tools don't happen overnight.
Being tough to introduce younger generations, when we're gone, I'm afraid that's all she wrote.
