The smallest skew I have is 1/4", and I rarely use it. At an AAW symposium years ago, I watched Alan Lacer turn a small piece with (IIRC) a 1-1/2" skew. But I don't have his skill level, so I generally use a 1/2" skew.No matter what size your skew is they still work the same. This is not my smallest skew.
Brian, I guess I was not clear. Consider the upper shew in the picture. If you pushed the skew to the left, the barb would enter a hole in the end of the handle, preventing any rotation of the skew.Denis can you please explain I am having a mental aberration
The jig has a barb next to the through-hole for each size skew. There is a corresponding hole in the inner end of each handle.
John, you have me beat. My smallest is a 1/8 in flat skew. Regarding sharping of a round screw, it is analogous to the sharpening of a gouge. If you are good at it, freehand sharpening is fastest. Otherwise jig sharpening is the way to go for most turners.I just sharpen by eye which is much easier with CBN wheels because they run so true. My mini skews are initially shaped by hand on a 600 grit hone under my 20x stereo microscope. I have skews down to .008".
