Powermatic PJ882 Rabbeting, Jointing Short or Thin Work, Jointing Warped Surfaces, Beveling

Rabbeting

A rabbet cut requires removal of the guard. Use extreme caution and keep hands clear of cutterhead. Always re-install guard immediately after rabbeting operation is completed.

A rabbet is a groove cut along the edge of a board. See Figure 42. The width and thickness of the wood to be rabbeted depends upon the width and length of the rabbet. However, never rabbet a piece of wood less than 12” long.

Use push blocks to rabbet cut whenever possible. The rabbeting capacity is 1/2”.

1.Disconnect jointer from power source.

2.Set fence for desired width of rabbet.

3.Check width of the rabbet by measuring the distance from the end of a knife in the cutterhead to the fence. NOTE: The knives must be extended beyond the cutterhead by 1/32”. (see “Replacing Knives in the Cutterhead” for this procedure).

4.Re-connect power. It is easier and safer to take a series of shallow cuts. Lower the infeed table 1/32” at a time and make successive cuts until the desired depth of rabbet has been obtained. See Figure 42.

Jointing Short or Thin Work

When jointing short or thin work pieces, use a push block to eliminate all danger to the hands. Two push blocks are shipped with your jointer. You can also make your own easily from scrap material. Examples are shown in Figure 43.

Jointing Warped Surfaces

If the wood to be jointed is cupped or bowed, place the concave side down, and take light cuts until the surface is flat.

Avoid forcing such material down against the table – excessive pressure will spring it while passing the knives, and it will spring back and remain curved after the cut is completed.

Beveling

To cut a bevel, lock the fence at the required angle and run the work piece across the knives while keeping it firmly against the fence and tables. Several passes may be necessary to achieve the desired result.
