20Figure 10-310.4 RabbetingA rabbet is a groove cut along the edge of aboard. See Figure 10-4. The width and thicknessof the wood to be rabbeted depends upon thewidth and length of the rabbet. However, neverrabbet a piece of wood less than 12” long.Figure 10-4Note: The knives must be extended beyond thecutterhead by 1/32”. See the Setting Knives forRabbeting and Nicks section on page 20 for thisprocedure.A rabbet cut requiresremoval of the guard. Useextreme caution and keep hands clear ofcutterhead. Always re-install guardimmediately after rabbeting operation iscompleted.Use push blocks to rabbet cut wheneverpossible. 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 thedistance from the end of a knife in thecutterhead to the fence.4. Re-connect power. It is easier and safer totake a series of shallow cuts. Lower theinfeed table 1/32” at a time and makesuccessive cuts until the desired depth ofrabbet has been obtained. See Figure 10-4.10.5 Jointing short or thin workWhen jointing short or thin work pieces, use apush block to eliminate all danger to the hands.Two push blocks are shipped with your jointer.You can also make your own easily from scrapmaterial. Examples are shown in Figure 10-5.Figure 10-510.6 Jointing warped surfacesIf the wood to be jointed is cupped or bowed,place the concave side down, and take light cutsuntil the surface is flat.Avoid forcing such material down against thetable – excessive pressure will spring it whilepassing the knives, and it will spring back andremain curved after the cut is completed.
