Wiring

[Austin Carr]

I seem to remember that Wheatley and Morgan's vintage car restoration book said the method used was cotton thread wrapped round the ali cover and then varnished. Sounds a proper faff. I'm probably entirely wrong because it's about half a century since I read it.

braiding must be unwound during wiring installation, temporarily bind the outside of the cable approx 100mm back, this will prevent undue loosening of braid. then wind back into place to cover outer and secure end, which was originally whipped with cotton then varnished, a modern alternative is to use 'heat shrink' sheathing.

You weren't wrong at all.
