I meticulously cleaned the stubs so they would take solder fast, gently prewarmed the neck with a plumbing torch, then quickly soldered the new wire with an iron (dwell too long and the glass will crack and bye bye vacuum), then I threaded the new wires through the base, exhaust siliconed it to the neck and soldered. .

Then waited for your heart to slow back down to below 200 BPM, and your blood pressure to drop back out of the danger zone?
