Grinding Jig. This Skew Grinding Attachment can be used to quickly and
easily grind a skew.
Skew Grinding Attachment
This product was designed to use with the Oneway Wolverine
One reason that the skew leaves such an incredible finish on work pieces is due to its
very thin edge which leaves naturally cleaner cuts. This creates a problem with sharpening
the skew as this thin edge will easily fold over during grinding. ONEWAY's Skew Grinding
Attachment minimizes this problem by allowing the skew to be mechanically held. The unique
offset handle position actually reduces the hollow grind generated and leaves a stronger
more predictable tool.
Until now, we have been using the Wolverine Grinding Jig's Vee-Arm
to grind skews. Straight from the pocket, a hollow grind can be produced at any angle you
wish to achieve, or the rounded toe used by some turners. However, two problems occur
using the Vee-Arm:
- the bevel of the skew should be flat, and this method does
produce a hollow grind
- the cutting edge and bevel are not parallel.
the first problem seemed impossible, to get a flatter grind you need a bigger wheel, so we
set out to solve the second problem. The result was the ONEWAY Skew Grinding attachment. Very
simply the jig is two pockets offset 3-1/2" to either side of center of the wheel.
When the handle of the skew is placed in these pockets, the cutting edge becomes square
to the wheel. But after we tried the jig something amazing happened. The bevel flattened
itself out, which solves the first problem; excessive hollow grind. How does this happen?
Well, as the tool is moved side to side on the wheel, the offset position of the handle
forces the tool slightly up and down the wheel. As the tool is forced up the wheel it
grinds more off the back of the bevel and flattens the grind. The Skew Grinding Attachment
produces a virtually flat bevel with greatly improved cutting characteristics. This
fixture is a highly recommended option with our Wolverine Grinding System.
The skew, in order to cut effectively, should be ground with an angle of 70 degrees to
80 degrees looking from the top, and an included angle of 20 degrees to 35 degrees,
depending on the wood to be cut and personal preference. The surfaces should be flat, not
convex or concave. In an attempt to obtain a flat surface, some turners will grind the
skew on the side of the grinding wheel, but this method is not recommended as some
roundness will occur and for safety reasons.
