So, I would prefer not to drill glass since it's not my area of expertise, and we have many other things want/need to create. Perhaps that will happen someday. I've already built some wooden tools, but I haven't had the time to do it on a larger scale. You can place an order via email, and I'll make one for you when I'm back at the lathe. I also use one that fits perfectly into the chamber or is suitable for dabbing. Can't glass beads be placed in the tube? Colored glass mouthpieces are not a problem. But I need to see how well this catches on first. Best regards.
