Holly mackerel How did you do it?????? What type of an edge did you put on it?? From the work you posted on here before i bet the handle would be something that would fit that head.... Nice job

Hey Sasha,
Both edges are convex ground. They were originally coarsely put on with a rough file. I did those on a slack belt of a belt grinder. As traditional with the double bits, one is thinner and sharper, and the other is thicker and less sharp for "dirty" work.
As far as how I did it, I cheated a bit. Everything I did can be done by hand with enough time and enough patience. But I used a KMG grinder. It has multiple attachments.
Basically for squaring the top and bottom, I used the flat attachment. I then switched over to a slack belt, and knocked the edges of just slightly. Then, I put the 8" contact wheel on to do the entire surface finish. I went from 60 grit down to 9 micron.
I saved the convex edges for last because I did not want to cut myself
Sounds like a lot, but it really did not take all that long.
