Part 10 [1] of his prototypes series also features incredibly impressive precision. He starts off with a $10 piece of aluminum that took maybe an hour or two to make, and is completely accurate down to nanometers. I worked in a nanotech lab with an …

In High precision air bearing CNC lathe and grinder [video]Bolting parts together is better because it means you can disassemble it for transport or maintenance. Perhaps surprisingly, this doesn't harm the performance. Lathes, and machine tools in general, are built for extreme stiffness, not extreme strength. Dan Gelbart has a very interesting demonstration showing …
