i usually put a 15 degree heel on my flat and square gravers, using my power hone diamond wheel and angle fixture, power off
for my round gravers, i use a 15 degree and hand spin/twist the graver, in the angle fixture, to match the round face as best as i can…without creating a point!
with the onglettes, i am using the yellow diamond bond wheel in a flexshaft…not being too successful
i think it is a matter of figuring out how to hold the graver in one hand and the flexshaft in another, so that i can deliberately and softly/ smoothly move the graver correctly, and see what i am doing, to create the heel shape
it looks like ben is rocking the graver up a bit
and his heel is a curve
two kind of heels for onglette
1: a parallel heel running along the edge of one or both sides, with a very tiny curved angle at tip
2: a bigger smoother curved angle heel along the belly toward the tip, with a slightly polished angled tip…
i am trying steeper face angles…60-65, instead of 45, to strengthen tip…i aim for 15 degree heels…maybe too much …
i need help too…i struggle!
