For years, I have used a v-arm and a bench grinder to sharpen my spindle roughing gouge.
I recently read that the v-arm shouldn't be used this way because it traps the tool and can kick back. Bah! Has never happened to me in 7 years.
A DAY after I read that it happened to me. Thank goodness this was a CBN wheel, because I might have shattered a friable wheel.
Now I am scared to sharpen my roughing gouge this way.
How do YOU do it?
The only way I can think to do it is to set the v-arm loosely. This will provide a pivot point, but will allow the arm to slip in the event that the wheel catches the edge.
