8. Drive Cylinder: This double acting pneumatic cylinder
connects the motor carriage to the machine case and moves
the carriage through the rout and drill cutting phases of the
cycle. The cylinder rod extends to move the carriage to the
rear of the machine, which brings the router up to cut the
pocket. When the cylinder rod is withdrawn, the carriage
moves forward and the pilot drill is extended to bore the
pilot hole into the pocket.
9. Router Stop Switch: This magnetic proximity switch is
mounted on the router stop plate inside the rear of the
machine. At the end of the rout phase of the cycle, the
carriage interrupts this switch to signal the start of the drill
cycle, sending the carriage forward.
10. Drill Stop Switch: This magnetic proximity switch is
mounted on the inside front of the machine case to the left
of the carriage as seen from the rear. At the end of the drill
cycle, the carriage interrupts this switch to signal the end of
the pocket cutting phase of the cycle. At this point the
carriage returns to the neutral position and the clamp
releases the stock.
11. Control Box: The control box is the sheet metal enclosure
that houses the electrical and pneumatic controls. Mounted
on the control box and accessible from the outside are the
router speed control valve, the air inlet port, and the power
switch. Also mounted on the control box and accessible
through the rear door are the pressure regulator, the duplex
power outlet for the motors and the solenoid valves.
