|Making new, old round crystal housings|
|I was looking at the
"Paraset Warehouse" and saw covers for crystal holders.
I make "false military plates" like this:
|2 - Use thin PCB (0,8mm,
sometimes used for VHF circuits) and engrave it like a printed
3 - Put a (thin) coat of black paint everywhere, wait for drying
4 - Rub with thin sandpaper fixed on a flat block of wood to make copper reappear
5 - Put the plate in chemical tin for PCB
6 - It is possible to cover with a varnish but not necessary ...
|You have now a black and white plate which looks like old ones.|
