Edge Jointing

Figure 6-4. Always try to work so you are cutting with the grain of wood; when this isn't possible, make very light cuts, very slowly. Note: The depth of cut is exaggerated for clarity.

The edging cut is made by moving the stock so the knives will be cutting with the grain of the wood (Figure 6-4). Warning: Working against the grain seldom produces a satisfactory surface; it also increases the danger of kickback and splintering.

If the cutting action is not smooth or if you feel the stock pushing back against your hands, the chances are that you are working against the grain. Stop the pass immediately and reverse the position of the stock.

If you have to make a cut against the grain, take a very light cut and make the pass very, very slowly.

Depth-of-cut settings on edge jointing cuts never should exceed 1/8". A setting of from 1/32" to 1/16" usually does the best job and wastes less wood.

Figure 6-5. (A) Begin the cut using your left hand to steady the stock and your right hand to feed it forward. (B) As the stock nears the halfway point, reposition your left hand to the outfeed side of the jointer. (C) Continue to steady the stock with your left hand while you move your right hand to the outfeed table. Finish the cut by pushing the end of the stock past the cutterhead with both hands.

Although the jointing cut is a smooth movement from start to finish, it may be thought of in the three steps shown in Figure 6-5. The better side of the stock is placed against the fence with the work edge down on the infeed table. Hands should be placed to hold the stock down on the table and snugly against the fence. The left hand holds the stock down 4" to 6" before the first bump on the top of the fence and guides the stock. This permits both side and down pressure to hold the stock firmly against the fence and flat on the table. The right hand is placed near the end of the stock and feeds the stock forward. Warning: If the stock is below the top of the fence, always use a push stick or push block to complete the pass.

As the stock moves over the cutterhead, the guard moves aside to permit its passage. The left hand does most of the work of keeping the stock snug against the fence and down on the table, while the right hand moves it forward. Always try to keep hands hooked over the top of the stock. Warning: Do not allow your hands to pass directly over the cutterhead.

At the end of the cut, the hands are still in about the same position on the stock. Avoid heavy downward pressure at the end of the cut, since this might tilt the stock into the cutter, resulting in a gouged end.

Figure 6-6. When jointed boards are butted edge-to-edge, they should have these qualities.

If the machine is properly ad-justed and the pass is made correctly, the jointed board will have edges that are square with its face. Edges of a group of jointed boards will fit against each other without gaps, checking out in all respects shown in Figure 6-6.
