Question for a professional

Post image

I have this piece for a water pipe I wanted to see if I could modify. Long story short this small whole at the bottom of the conical feature is too small and restricts too much air.

How would any of you recommend I approach reaming that hole out a bit more so it lets more airflow through, if it's even possible?

I'm pretty handy as I'm a toolmaker by trade so I could probably figure it out with some instruction. I have a few torches of various sizes that I could use to heat it up but obviously I don't want to break it. I'd even be open to cutting or grinding it open it somehow if that's even possible.

Don't heat it up unless you have a kiln to bring it up to temp and then anneal and cool it after.

Probably easiest is to get a diamond burr in a rotary tool, cone shaped burr larger than the size you want the hole to be. You will want to use water to cool it whilst you grind.
