News flash, long before there were CNC machines people were making precision parts. My grandfather was a gear maker, and was one of the finest in the country according to the people that sought him out long after he retired. When computers first came on the scene they used to get the best engineers they could find to walk them through the process so they could get the machine to do it the same way. I remember they called him out of retirement to help them make a gear for a giant shovel (used at strip mines, looked like a house on a turn table). My grandfather said they had programming engineers watching everything he did, and how he bets that somewhere there is a computer that stops and scratches it's imaginary nose before moving to the next step.

The point is, the old equipment is just as capable as the new fancy stuff with the right operator. The new stuff is faster and easier to duplicate the same part over and over. And the new stuff doesn't require the same level of skill from the operator, just from the programmer. The new stuff also repeats the same mistakes over and over if they were programmed in, or something becomes out of tolerance.

You'd be amazed at how many people can't do a simple task like turn a brake rotor because they can't grasp the concept of to big a cut or a dull bit. And when you apply it to turning a exotic metal the number of people that can't goes up drastically. And there is more to metal work than just how it looks when it is done, so I'll take GN7's advice when he says this shop knows what they are doing. I also trust people that work with these metals to school us. I know the precision that Westernaero has to meet on aircraft as well as seeing some of the great stuff he is turning out. This site is fortunate to have the people with real world experience and top notch skills.
