I ground a HSS tool bit with the radius on itHow did you do those curves? Free hand tooling? Large ground tooling?
And free handed it some working it back and forth
Until I got it right then dressed it up with some very fine needle files , and then fine sand paper
Knurled the two outside edges . And smoothed
Them with the needle files.
I think I made three deferent tools at least
Maybe four . It has been 25 years at least
I didn't use nuts to make them out of
I used round stock Stainless Steel drilled and bored And parted them off
