Hi there everyone. I've been building hilts for a few years now, and recently finished my first working saber. It's a Luxeon III powerred by a 9-volt battery through a 1000mA "BuckPuck". So far, I'm not impressed with it's brightness, compared with what I've seen in vids that people have posted. Either I don't have enough power, or I wired it wrong. Advice would be appreciated. MY MAIN QUESTION IS THIS: Will it compromise the durability of the blade if drill a countersink hole into a 1/8" walled Corbin style battle blade? I've been having a problem with the blade slipping out of the holder while twirling it. And I've wrenched the thumbscrew down as tight as I can every time.
