Powermatic 4224B Tool support, Indexer, Locking handles, Live center and cone

9.3Tool support

A 14” tool support is provided with your lathe. It is designed to allow adjustment for height, position on the bed, and angle to the work.

Loosen locking handle on tool support base (C, Figure 25) to slide support base forward or back, and to angle it to the bed. Tighten locking handle firmly before operating lathe.

Loosen handle (D, Figure 25) to raise or lower tool support and angle it to the work. Tighten handle before operating lathe. If tool rest post begins to slip, tighten screw (E, Figure 25).

now be removed by holding body stationary while unscrewing cone.

9.6Indexer

The indexer is used to create evenly spaced features in a workpiece, while keeping the lathe spindle locked; for example, when cutting flutes on a spindle blank with a router, while the spindle blank is secured between lathe centers.

Index positions are inscribed on the spindle, matching hole locations on the handwheel.

To use indexer (Figure 27):

1.Loosen handle (A) and position arm until indexer pin aligns with the desired array of holes.

9.4Locking handles

Locking handles, such as D, Figure 25, are adjustable. Simply lift out on handle, rotate it on the pin, then release it, making sure it seats itself on the pin.

9.5Live center and cone

The live center cone, shown in Figure 26, screws clockwise onto the threads of the live center body.

Figure 26

To remove cone from live center, first insert live center pin through hole in live center body as shown in Figure 26. If pin will not insert at first, rotate cone until pin can be inserted. The cone can

2.Rotate spindle to position by observing scale on spindle.

3.Push indexer knob until pin enters handwheel hole. Rotate indexer knob to engage threads and secure handwheel.

NOTE: Tighten indexer knob only enough until pin fully engages hole and spindle will not turn. Do not overtighten, as this could cause slight deflection in the spindle.

4.Perform the operation upon the workpiece.

5.Unscrew knurled knob until indexing pin releases; turn handwheel to next indexing position, and re-engage indexing pin.

IMPORTANT: Release index pin before turning on lathe.

The indexer assembly can be removed from the lathe by loosening and removing locking handle (A, Figure 27).
