Powermatic 54HH, 54A operating instructions Beveling, Skewing Shear Cutting

Beveling

Beveling an edge is the same operation as edge jointing, except that the fence is tilted to a specified angle.

‰Make certain that the material being beveled is over 12 inches long, more than 1/4 inch thick and 1 inch wide.

‰Although the fence may be tilted in or out, it is recommended that the fence be tilted in toward the operator (as shown in Figure 39) for safety reasons.

Figure 39

To bevel:

1.Use a bevel gauge to determine the desired angle. Then set the fence to the same angle.

2.Inspect stock for soundness and grain direction (Refer to Direction of Grain on page 23).

3.Set the infeed table for a cut of approxi- mately 1/16.

4.If the board is bowed (curved), place the concave edge down on the infeed table.

5.Feed the stock through the cutterhead, making sure the face of the stock is completely flat against the fence and the edge is making solid contact on the infeed and outfeed tables (Figure 39).

For wood wider than 3 inches – hold with fingers close together near the top of the stock, lapping over the board and extending over the fence.

For wood less than 3 inches wide – use beveled push blocks and apply pressure toward the fence. Keep fingers near top of push block (Figure 40).

Several passes may be required to achieve the full bevel.

Figure 40

When beveling short material use one bevel hold down and apply pressure toward the fence. Keep thumb above the ledge on hold down block (Figure 41).

Skewing (Shear Cutting)

When edging or facing burl or birds-eye maple, it is not unusual to deface or mar the surface being finished. This is caused by the cutterhead blades at times cutting against the grain. In order to prevent the defacing or marring of this type wood, it is necessary to skew, or angle finish, the material being worked (see Figure 42).

1.Release the fence locking handle and remove the two hex nuts and flat washer holding the fence to the fence support (see Figure 3 on page 10). Remove the fence.

2.Remove the key from the fence slide base.

3.Replace the fence assembly at the desired angle across the cutterhead. Secure the fence to the support with the two hex nuts and flat washer, then tighten the fence locking handle.
