During the motion structure assembly we were puzzled why things were not lining up, and why the crossheads would not go in between the cross head guides when assembled. Checking the crosshead guide yolk and the crosshead size showed everything to print, yet the opening was wrong. Taking the guide bars out and measuring them revealed a .007 thou taper! The guide bars moved during the machining operation due to releaving the internal metal stresses.
