Making a new HT lead, modern copper cored HT lead is now 7mm diameter and shiny PVC.

I use a bit of heat shrink to increase the size to about 0.34".

The larger size fits the old coil pickup, and heat shrink look more like the original rubber HT lead.

New solder on end, and good to go.

The green spark plug co is a great supplier of all sorts of HT leads, connectors etc. should anybody be looking. They also do cloth wrapped HT leads.

No it looks like it is brazed, just think some rust is holding it together.

Did not want to distort the angle bit, so will bore it out.

Found out why It would not come apart, it was nailed together, with an iron nail.

So bored it out, made up an ali mandrel so I could use the tailstock to align it in the 4 jaw.

Did you know that pre 1992 2p and 1p are made of bronze making then worth 60% more than their face value....
