Grounding Vintage Sewing Machines
I took my Kenmore's foot control apart and nearly fainted.
This thing has a metal casing, and inside there are coiled resistance wires. If one of those let go, it could easily touch the case and make it live!
The metal body of the machine with single-insulated wires makes me a little uneasy too, though I have carefully inspected them for damage.
Has anyone rewired their vintage machine to bring it up to modern safety standards?
I have an idea of how I could go about it, but there's no point reinventing the wheel if it's been done before.
