The table on the mill is thicker than the table on the lathe because of the greater forces transferred to the table in milling and the requirement for stiffer setups. When using the vertical milling column on the lathe, the table can be “beefed up” with the addition of this plate, which adds 1/2″ of thickness to the table. It also serves as a tooling plate that protects the surface of your lathe table from damage. The plate attaches to the table utilizing four recessed cap screws and T-nuts. It should be removed for lathe turning to maximize the diameter of the part that can be turned and so that the standard tool post can be used.
