Use only the included special low-head bat pins, 1" in length, to attach the disc to the potter's wheel . Regular bat pins will stick up above the surface. If your wheel requires 1 1/2 " bat pins, e-mail or phone and I'll send those instead.

I use the disc to flatten the bottoms of all my bowls after the bisque firing. It's a lot easier to do the sanding/grinding in the bisque rather than after the ware has been glazed. This grinder works very well for this purpose.
