You can believe that, in Aluminum, on a rigid machine, with a rigid setup, with sharp tools, and with the horsepower. Most home machines lack the horsepower or rigidity to do that. The home machine I am building will almost do that, but not quite. The one at work will, and more up to about .010, but that takes 20 horsepower.
