Hi Folks
Just interested in how other members restore things like body-tip-spot resistors and old bakelite Dubilier silver-mica caps. I realise there is some availability of NOS for both of these

These are my thoughts on the subject:
Resistors - as new MF types are so much smaller, I thought of moulding a cylinder round these, and making the leads exit radially at the ends, so they could be wrapped around, and lightly soldered, followed by painting. Material - maybe plaster-of-paris with a bit of PVA wood glue in the mix?

Capacitors - Mould brown resin around a modern cap - use an original for a mould male, but what would you use as a mould material? Would p-o-p be fine enough, or would you use one of the latex-based materials? Whatever you used would have to be in a 2-piece mould because of leads emerging.

What does the team think?
