I'm trying to do the method where you cut a joose groove in the insulator. Seemed easy enough, but I can't get the insulator out! Any suggestions? I've tried pushing it out with a screwdriver using my hand. I haven't tried the hammer because I'm scared to ruin the insulator. If someone says bang it out though...I will. This may not be the best conversion but if you got no tools it's the only conversion.
