at ATF, during which these machines were refined to an impressive level of precision. Theo Rehak, the current owner of much ATF typecasting equipment, and author of the definitive treatise Practical Typecasting, explains that the Bentons demanded that any deviation in machining or casting be within two ten-thousandths of an inch. Most modern machine shops are equipped to measure down to one thousandth of an inch. As an advertising device, in 1922 ATF manufactured a piece of type eight points tall (0.11 inch) containing the entire Lord's Prayer in 13 lines of text, using a cutting tool roughly equivalent to a 2000-dpi printer.
