I'm working on building one. It's been a slow process as I can get access to the tools I need.
I bowled semi-pro for years and want to make a bowling pin hookah. I have a brand-new pin that I drilled all the way through with a 3/4" drill press. Now I need to engineer the stem to go through the pin, a good tray that will keep heat from melting the plastic of the pin, and a way to attach it to a base. I'm working on it.
