I think CNC machining has changed the whole landscape. If the final 20% of the work is done on a lathe and a Bridgeport, even if the machine has a digital read-out someone has to set the piece in the vise, crank the table up or down to the correct location, turn a wheel to set the depth of cut ... and read the blueprint to figure out what needs to be cut and by how much. If you want to do two receivers, you go through all the steps twice. If you want to do ten receivers, you go through all the steps ten times.
With CNC, all that is taken care of by whoever writes the program. There is no real "setup" -- just mounting the piece in the appropriate orientation in the machine, and pushing the button. So perhaps it comes down to who writes the program. If the major time expenditure to finish an 80% receiver by CNC is writing the program, then if I write the program, maybe I am doing 20 percent of the work. If Joe's AR-15 Shop wrote the program and all I'm doing is pushing a button, I don't see how I can claim I'm doing much of anything.

The newest CNC machine at Caspian Arms is larger than my single-car garage. Not exactly do-it-yourself grade equipment.csmsss said:Have you ever seen one of these CNC mills? There's no way on earth you would be able to set it up on your own premises unless you already have the facilities a commercial shop would need.
