Mount your pin in some scrap plywood, big enough to span your table saw. I just drilled a hole slightly under size and hammered it in.
Put a masonry blade on your saw. Mine was actually made for a circular saw, but it fit the table saw arbor just fine.
Raise the blade until it would just impact the tile, and then position your pin at a 90 degree angle from the center of the top of the blade. It's important to set the height first, as the blade will move forward and back as you raise/lower it.
Lower the blade and get suited up to get blasted by toxic dust. The dust that comes from dry cutting ceramic tiles, if it gets in your lungs, will basically never leave and can cause you life long issues. Wear a respirator!
I found putting a fan behind me and slightly off angle aimed out of the garage worked pretty well at keeping the majority of it off of me.
