Ever drop something and it just disappears? Just vanishes into thin air without a trace. I didn't even hear it hit the concrete floor. It's like it slipped in to an alternate demention as it fell to the ground. I looked for an hour and came up with nothing except dirty looks from my boss. I had to abandon my search. I didn't want to explain to my boss he's been paying me for the last hour and a half to look for the spring to my mod. He's a nice guy but he's not that nice. As of today I'm using it with a 18650 screwed all the way down to the battery. I need a spring. I'd like a nice copper or silver plated spring that fits. Anyone know of a vendor that carries them? I can get the diameter easy enough. Ill assume its about 1" tall. I'm not sure if springs are sold with a pressure rating or not. Do I need to know how much tension it has? Is there someone who sells the exact spring?
