Greg, if you ever want to get together and work on some grinding together, look me up. I'm just up the 405 from you and while I'm below an apprentice at this point, I'm sure there are things the two of us can pick up from each other. Just a thought. Most of my grinds are convex however I set a lot of my original bevels on the flat platen. This one is preheat treat with a 120 belt finish.
