And the physical sciences were deciphered only slowly, by a process of cut-and-try and cut-and-try again.

In connection with a graduated cross-feed screw this greatly facilitates the work over the usual cut-and-try method.

This method does away with the "cut-and-try" process, and will bring the finishing cut within 0.001 inch of the required size.
