In the new issue #164 on the top of page18, they show a drawing of a jig for sharpening a scraper plane blade. It basically holds a diamond sharpening stone at an angle of 30 degrees to a surface that the blade is laid flat upon. Then the blade is moved back and forth along the length of the edge being sharpened. This keeps the angle being sharpened constant. I have some problems sharpening my chisels freehand and was considering something like this to help.
Questions
1) Does it matter that the sharpening direction is along the edge instead of perpendicular to it? 2) Could this be adapted for sharpening chisels and plane irons?Thanks Frank
