The first 48 lobe Rosette cam I have is only 6.5 inches in diameter and has to be turned very slow to produce a smooth cut without bounce. In the photo above I'm duplicating the 12 lobe cam to a 9" diameter as a test. The 48 lobe Rosette cam also duplicated very nicely. The Corean cuts beautifully but is very messy as you can see in the photograph.
The next photo shows the phase hole drilling operation.
