I finally broke and spent the money on a Wolverine grinding jig after all this time. The reason I actually quit turning a couple years ago was because I couldn't sharpen and I ruined a spindle gouge trying to do it by hand. Anyway, my grinder is a Grizzly 6" which I plan to keep because I've already spent WAY past my permitted budget. My question is really about the Vari-grind. I've read several articles that say to extend it 2" on every grinder but I've read some articles that say on a 6" to only have 1-3/4" of tool extended. It's very confusing but I'd like to have it figured out by the time it arrives on Saturday. Please help.
