Mr Article99,
FYI,
Just in case you were not aware of this, You happen to have one of the best CNC tool and cutter grinder machine tool manufactures right in your back yard. The company name is ANCA and they are out of the Melborne area. Bayswater to be specific. I deal with the company often and I am sure they would be happy to help.
