I have made one of these from the various designs on the web. Basically it uses a 2inch wood block with a hole for the gouge and a dowel projecting at an angle from the base which pivots in a sliding arm. Geometrically, pretty much like the commercial product
It does produce a degree of side grind on my spindle and bowl gouges.
However, can someone enlighten me as to what adjustments to make to increase/decrease the amount of side grind for a given bevel angle?
As I see it, there are 4 variables:
1 protrusion of the gouge from the face of the block
2 distance between that gouge hole and the point at which the dowel leaves the block
3 the length of the dowel
4 the angle the dowel makes with the gouge axis (45 and 30 degrees in my case)
Which of these should I experiment with. I have tried meddling with all 4 but I just get more confused.
