I used 9000 RPM, a feed rate of 12.300". The tool I used was Carbide’s #112 with a depth per pass of 0.008". Also chose Brass as my material (even though it was Mokume).
To adhere my metal, I used the Blue Machinable Fixturing Wax that Carbide has, although I plan on switching to the White wax when I run out of the blue, because it’s water soluble. For now, I’ve found that soaking my pieces in a Goo Gone solution works great on the small pieces to remove the blue wax residue.
