I now have two quality scraper carbide inserts. One is made by Sandvik and the other was sold by Biax. Both are roughly 1" square.
I am aware of Rich King's suggestion to grind 4 different radii on the 4 sides of each insert. I may do that and I may not.
I know that green grinding wheels are sold for grinding tungsten carbide. I have never used one, nor do I own one. I do own several bench grinders, a surface grinder and a 1750 rpm motor set up to run Chinese diamond lapping plates. Plus, I have a buddy with a Baldor model 500 "carbide grinder", although I don't know if he has any green wheels.
It seems to me that trying to rough in e.g. a 40mm radius on one of those little Chinese lapping plates is not a very workable solution.
So I'm thinking about picking up a 6" regular type 1 wheel to put on a bench grinder. I have a Darex M-series base and motor, which make up a pretty good quality bench grinder.
Can you suggest a particular grinding wheel I should use?
