In the July 2005 issue of More Woodturning Mr. Holder explained how to sharpen a 5/8" rod bowl gouge on the Tormek. The information came from Torgny Jansson who works for Tormek. It requires the protrusion of the tool be three inches from the SVD-!85 jig. A wooden spacer 2.05" is used to set the space between the wheel and the universal support. The jig itsself dosen't have a marking for anything higher than 5 but the jig is set to what would be 6. I don't own a Ellsworth gouge so can't say how this works but Mr. Holder says it makes the grind he was looking for.
