I was able to pull the positive block straight out of the deck with some pliers, and push the 510 post out with a screwdriver.
I don't have any insulators that are a direct fit (surprise, surprise) However, I can make one fit with some grinding.
But then it hit me.... How about JB Weld? It's non-toxic, non-conductive, and temp safe up to 600 degrees F (higher than PEEK). I can smear a bit into the insulator channel and make my own custom fit insulator that isn't ceramic lol.
Does anyone have any thought on why this would not be a good idea?
