I have not built anything with an 80% lower, but, I have acquaintances with CNC shops that have dinked with them for themselves and had good luck. However, they all believe that unless a person has the machinest skill set and the machines that they and their shops use, that it is not a very good idea for an average person to build one of these things out of their garage. If you can get the file in machine you may get a CNC shop like this to show you and let you load the program into their CNC mill, charge you a fee to "rent" their machine and time, let you load the 80% lower in the fixture, and let you push the button to start the program milling and thus finishing out the 80% lower, but that scenario is most likely near impossible to find.
A good piece of glass is like a fine piece of ass. There is no known substitute known to man, and neither are cheap.
