Vari-Grind Adjustment for Geiger's Vertical Solution

To address the needs of the turners using my Vertical Solution sharpening system I offer the following set-up instructions for setting up the Vari-Grind jig:

1: Place the Vari-Grind Jig face down on a hard surface as shown in the photo. It’s best if you can clamp it into this position.
2) Loosen the wing nut so the adjustable stem moves freely.
3) Using a ruler, adjust the stem until the very top of it is 6 ¼†from the surface you have clamped the Vari-Grind to.
4) Tighten the wing nut securely. Verify the stem is at 6 ¼†after tightening the wing nut.
5) Place a 60° hollow ground gauge (supplied with the Vertical Solution and available from me separately) into the Vari-Grind just as you would a gouge (see photo in a subsequent post- it appears I can only post 1 photo per message).
6) Using the protrusion gauge on the Vertical Solution, set the distance the 60° gauge protrudes from the face of the Vari-Grind.
7) Using the horizontal positioning gauge provided with the Vertical Solution, set the distance the V-notch is from the face of the grinding wheel.
8) Tighten the cam-lock on the Wolverine receiver securely.
9) Position the stem of the Vari-Grind into the V-notch and place the hollow ground end of the 60° gauge against the grinding wheel.
10) Loosen the setscrew and adjust the v-notch vertically until the hollow ground end of the 60° gauge accurately matches the curvature of the wheel.
11) Tighten the setscrew very securely.
12) Re-grind your gouge in this new position. If you have to take very much off the tip to match the angle, be sure to re-set the distance the gouge protrudes from the face of the Vari-Grind before you finish.

The results will be that you will have a very accurate 60° angle at the tip of your gouge and the side grind will mimic what you will get from an Ellsworth jig very closely. So close I cannot discern the difference.

Note: If you have a Vari-Grind Jig and other jigs, such as the Ellsworth etc., you will not get the same results without re-adjusting the vertical position. My suggestion is to choose one jig and stick with it.

The whole procedure should take about 5 minutes and only needs to be done once.

The 60° gauge is 5/8†diameter and designed to fit into any of the popular jigs. With an Ellsworth jig, which has a fixed stem, skip the part about adjusting the stem.

Let me know if you have any questions.

Var-Grind jig with Geiger's 60 Degree Gauge

Here's a photo of the Vari-Grind jig with my 60 degree gauge inserted. Note: this gauge will fit into any jig that will accept a 5/8" diameter gouge. The top is milled flat so it will orient in a jig just like a gouge.

I believe this is a very accurate method of setting the angle at the tip of a gouge because:
1) The protrusion distance is identical to what you will use with your gouge 2) The hollow grind at the tip of the gauge is ground using an 8" diameter mill to mimic the same hollow grind you would get with an 8" diameter wheel. 2)

Even if your wheel is slightly larger or smaller than 8" the radius is so close to the same that I doubt it will not make greater than +/- 1 degree difference. I have used it when setting up my Vertical Solution on my TORMEK and it worked quite well.

Also it is adjusted with the stem of the jig set into the V-Notch just as you will be doing when sharpening your gouge.
