I am looking for a bowl coring system I saw in a post 3-9 months ago. It is for strait walled bowls. A groove was cut to depth then the tool was inserted, the blank turned by hand a few rounds then the lathe was ran at low speed until the saw blade cut the bottom of the core off. The tool is a saws all blade that has been cut and welded to a 90 degree angle and mounted to a handle.
If anyone can refer me to the site I would appreciate it.
