Yeah, you said it. Be careful. Slow and steady, and go up in small increments on drill bit size if necessary. Keep an eye on the chamber so you don’t overshoot the juncture of the chamber and draft hole by drilling too far. It drills easily, so it could be easy to do. The stummel is what you don’t want to screw up. Replacement stems are available and cheap if you screw the stem up. Or just want to drill out a straight one with a tapered drill bit and bend it yourself (assuming it’s a bent stem you want)Any tips for drilling it out? Just be careful I guess?
