Obtaining now done two modifications, you will find several other aged synchronous motor clocks that I have that will require similar awareness. No less than I understand that once concluded, I'm able to lay my paranoia to relaxation and run my favourite artwork deco synchronous clock without having stressing about an electrical failure.
Vacuum impregnation with varnish is good, and can make the completed job mechanically tranquil and search pretty Experienced, however it's under no circumstances needed. Bear in mind the clock will now be running at only 16V, so sturdy insulation is not required.
