Re: Ellsworth grind from a Sorby jig.

>Oneway now offers a version of the varigrind that will take larger gouge diameters. I don't know if they offer any sort of upgrade kit for existing owners.
I'd be interested in more details about how you use the Sorby jig with the Wolverine. I'd like to investigate this combination.
As for the original question, I too find the Sorby jig and the Tormek on which it is based to work quite well to maintain the Ellsworth and Glaser grinds. As most know, a good way to make sure you have the settings right is to blacken the tip with a Magic Marker then turn the grinder by hand to make light marks on the tip. Once you get an even removal, you know you have a precise duplicate of the original grind.
