Knife Grinding Jig
I made the jig to achieve consistent grinds on both sides of the knife without having to reposition the blade, the jig has a definite location point
Cutting Flat Bar to Size
I used 12 x 6 mm bar cut to 64mm and drilled 3 holes at 5mm and tapped the middle hole through both bars and then tapped the holes on the ends on on piece only.
I enlarged the holes on the other bar so that the bolts would go through one bar and thread into the other
Cutting Slot in Angle
I cut a slot in the middle of a piece of 50x50x5mm aluminium angle corresponding to the size of the bar knife holder and drilled and tapped a M8 hole for the angle grind adjustment.

Cutting Knob Tread Down to Size
need enough thread so it clamps knife to angle Jig without touching the knife
