This bigger Vari-Grind Jig is made to handle larger gouges from 1/2" up to 1-1/8 in diameter. It can be used for sharpening fingernail grinds on spindle gouges or side grinds on bowl gouges. It is used in the V-Arm for the Wolverine Sharpening Jig.
The tool is secured in the jig by tightening the knob on top. It has a padded bearing that tightens down across the flute of the gouge being sharpened.
