Hey Al,
If this machine is anything like my old machine, you will find that Rod 1 is there to act as a 'Hard' stop between the lower saddle and the Tailstock body. Rod 2 is the Limit switch activator to trip the overstroke command if the user has not set the Z positive limit position correctly.
I never had to manually undo any bolts to move the tailstock as ours was a tow-along model. Try using G152 Wxxx where xxx is the "W" axis position you want the tailstock to move to.
The G152 command automatically moves the A turret into position to align the tow-along shaft, providing you have set the Z positive limit to allow the A turret to move into position. It then engages the link shaft and unlocks the tailstock clamp. The tailstock is then dragged along to the nominated position and clamped. The A turret will then move back to centre the tow-along shaft in the link hole to avoid hanging the shaft up on the edge of the hole.
If the machine does have the G152 command, it should also have manual link/unlink buttons on the operator panel.
Cheers
Brian.
