4-Way Tool Post

The 4-way tool post is mounted on top of the compound slide, and allows a maximum of four tools to be loaded simultaneously. Quick indexing to different tools is accomplished by loosening the top handle, rotating the tool post to the desired position, then re-tightening the handle to lock the tool into position.

Tool Needed	Qty
Tool Post T-Wrench	............................................... 1

To load the tool post:

1.Choose the desired cutting tool.

2.Loosen the tool post bolts so that the cutting tool can fit underneath them.

Note: If necessary, place one steel shim of the required thickness underneath the cutting tool, so the cutting tip is properly aligned with the workpiece. The shim should be as long and as wide as the cutting tool

to properly support it, a set of standard automotive feeler gauges work well for this.

Over-extending a cutting tool from the tool post will increase the risk of it breaking during operation, which may cause metal pieces to be thrown at the operator or bystanders with great force. Only extend a cutting tool 2.5 times the width of its cross-section or less (i.e., 2.5 x 0.5" = 1.25").

3.Firmly secure the cutting tool with at least two tool post bolts shown in Figure 79.

Aligning Cutting Tool with Spindle Centerline

For most operations, the cutting tool tip should be aligned with the spindle centerline, as illustrated in Figure 80.

(view from tailstock).

There are a number of ways to check and align the cutting tool to the spindle centerline. Below are two common methods:

ssAlign the tip of the cutting tool with a center installed in the tailstock (refer to instructions that follow). For this to work, the tailstock must be aligned to the spindle centerline (refer to Aligning Tailstock on Page 44).

ssMake a facing cut on a piece of round bar stock. If the tool is above/below the spindle centerline, a nub will be left in the center of the workpiece. Adjust the height of the workpiece, then repeat the facing cut to check the adjustment. Repeat as necessary until the center of the workpiece is smoothly faced.
