Auto Index, 3 hole Turret Press
A Turret Press that came without Auto Indexing can be upgraded to one that does. The upgrade to a three hole auto indexing press costs $30.00 and includes a new ram which is necessary. It also includes the actuator rod and clamps that hold the ratchets that move the actuator. The kit part number is 90579.
Auto Index, 4 hole Turret Press
The upgrade kit is $20 (catalog #90933), and includes a four hole turret, turret ring and indexer mechanism. The four hole turret ring is different than the three hole, so three hole turrets will not work in the four hole turret ring, and vise versa. In order to make room for lock rings the die circle had to be enlarged on the four hole turret, and the turret center line offset slightly.
If your press was not equipped with the auto index feature, you will need to order a new ram, part #TA2269 ($7.00) if you wish to install the auto index.
