Gadget for indexing gravers in the dual angle fixture

[rweigel]

Hello,
I grind a small flat along my round graver blanks, about 1-1.5mm wide, to have an index for shaping and honing them. This comes from the time when I used my home-made templates.
When I switched to the GRS dual angle fixture, I needed a possibility to index the alreday existing gravers. The flat is on top of the graver. The good thing is, one could machine a gadget for this with the hone and the dual angle fixture,
I took 3mm square tool steel, about 5 cm long, ground a flat along the whole length by clamping it in the dual angle fixture like a square graver and setting both angles to zero. One has turn the piece arround, to get the whole length ground. Then grind the two faces on top of the piece to an 120° angle for appr. 1.5 cm, to fit the angle in the „clamp“ (003-171 in the GRS drawing)
Now insert this piece in the dual angle fixture from behind, put the graver underneath and clamp it. Make sure that the flat on the graver is on top, were it touches the flat on the tool steel piece. The pictures explain it better than words can do.

Best regards,

Ralf
