The adjustable right angle tailstock supports the end of long stock held in the rotary table when it is in the vertical position. This allows you to accurately rotate a part between centers for milling or drilling operations.
Because of "tolerance buildup" in the various parts used to place the rotary table in the 90° position, it is not possible to build a tailstock that would come out exactly on center each time. By using a split base design with slightly oversize holes, the height of the tailstock center is adjustable slightly. Once set to exactly match your rotary table/right angle attachment combination, it should not need to be readjusted. It will work with both the P/N 3701 Right Angle Attachment and the P/N 3750 Tilting Angle Table in the 90° position.
