Valve pocket/bowl hog tools....

Yeah, you can use a ball driver for that. You still need to be fairly close to level though.

I will look and see if I can find my Goodson catalog. I used to have some bowl hogs but I gave them away.
Goodson quit carrying SilverSeal Hogs,......They basically want You to use their 3D Serdi-like setup w/the 70*75* what have You cutters, so I was told on the tele when I inquired............
