For all those machinists out there who have spent hundreds of thousands of dollars on five-axis CNC machines, I laugh at you! The answer has been lying beneath the soil since the beginning of time. We are able to get amazingly low tolerances on high grade 7000 series aluminum.....

Ok, in all seriousness we use a 3 axis CNC machine, manual lathe and at times a manual Bridgeport. Please excuse my friend and his....."creativity".
