I have many years of experience machining and using CNC machines, enclosure design, safe dust/particle/air handling, fixtures, and sound dampening. I teach machining and CNC - on the side - I'm a virtual machine and operating systems internals developer by day.
I'm a Nomad 883 Pro owner. I also have a PocketNC, a 5 axis CNC machine, and also have access to "big iron" like Bridgeport, Jet, CAMaster, ShopBot, Tormach, and Haas machines.
I do 3, 4, and 5 axis machining... for my own personal projects.
