For my wand tip I'm tossing in a ag1 bulb and want to hold it inwith a grub screw. I attempted this once the hole drilled and tapped fine. I installed the bulb and called it a night. Next morning I wake up to find hairline cracks spidering around the tube. Anyone got advice for a take 2. I have enough tube here for around 4 more attempts.
