- Created Main Beam, Gripper and Thrust (assembly): "The main beam and the parts that move the machine forward. Gripper shoes clamped against the walls anchor the gripper carrier, thrust cylinders push the cutterhead forward along the beam one stroke at a time, torque cylinders take the cutterhead's reaction torque, and the rear support holds the beam while the grippers reset."
