Design
See illustration on the next page. The jig comprises an upper base with a lower clamp
and two locking knobs for fixing the tool. The jig slides on the Universal Support on nylon
bushings across the grinding wheel. The edge angle is set with the Micro Adjust (3) on the
Universal Support (4).
There are two safety stops to prevent the tool from slipping off the wheel when grinding.
One inner stop (1) to be positioned according to the width of the tool and one outer stop (2)
mounted on the end of the Universal Support.
The jig lines up the chisel to its upper flat side, making it easier to mount it correctly (not
twisted). Conventional jigs need manual alignment.
The lower clamp has a ridge in the centre enabling shorter tools with a tapered shank to be
firmly mounted, e.g. Japanese chisels. The upper base, which lines up the tool, is designed
so the clamping pressure is distributed to the ends and the tool mounts firmly without a
heavy tightening of the knobs.
