People ask what fixture restoration tools it takes. The honest answer is that the tools are the easy part. What matters more is knowing what to do with them, but since folks are curious, here's roughly what's on the bench.
What's on the bench
There's the wiring side: strippers, cutters, the small hand tools for pulling old wire out and running new wire through. There's the mechanical side: screwdrivers in every size and slot, small wrenches, picks and probes for the fiddly work of getting an old socket or a stubborn fitting apart without breaking it. There's cleaning gear, brushes and cloths and the mild stuff for taking a century of grime off without stripping the character underneath. And there's the finishing side, which I keep to myself, both because it's where the judgment lives and because some of it isn't safe to hand a stranger a recipe for.
The tools don't do the work; I do. Knowing when a socket will come apart clean and when it'll shatter, how far to clean before you're erasing age, when a finish is right and when to stop, none of that is in the tool. It's in the hands and the eye, learned one fixture at a time. So I'm not going to write out a how-to, and it's not to be cagey. Do the electrical wrong and you've got a hazard; do the finishing wrong and you've wrecked a good piece, or worse. The right thing for me to do is hand you a fixture that's already done right, not a set of instructions and a wish of luck.
Salvager's Note: When you buy a restored fixture, you're not paying for the tools, which are ordinary. You're paying for the judgment, knowing which tool, when, and how far, that keeps an old socket or a fragile finish from being destroyed instead of saved.
