Hi Everyone! A few weeks ago I clicked on a Ceramic Arts Daily link for a woman who had built a clay cutting tool for slabs...both straight and with a circle attachment. I can't find the video anywhere and my local hardware store doesn't have all the supplies that were listed in the video: such as free-spinning lock nuts. Does anyone have the link to that video? I'd like to watch it again and see if I can figure out another way to make the tool. Thanks!
