Setting Outfeed Table
For accurate work in most jointing operations, the outfeed table must be exactly level with the knives at their highest point of revolution.
1.Raise the outfeed table to its highest point, and place a straight edge across it.
2.Rotate the cutterhead (using the belt or pulley) until one knife is at its highest point.
3.Lower the outfeed table until the straight edge contacts a knife. Rock the cutterhead slightly to make sure the apex of the knife is contacting the straight edge. Lock the outfeed table at that setting.
After the outfeed table has been set at the correct height, it should not be changed except for special operations or after replacing knives.
Examples of incorrect settings:
If the outfeed table is too high, the finished surface of the workpiece will be curved (Figure 20).
If the outfeed table is too low, the work will be gouged at the end of the cut (Figure 21)
As a final check of the outfeed table adjustment, run a piece of wood slowly over the knives for 6 to 8 inches; it should rest firmly on both tables (Figure 22) with no open space under the finished cut.
Spring Cutting
To spring cut, the outfeed table is lowered below the level of the cutterhead, as in Figure 23. Loosen both gib screws (A, Figure 23) on the outfeed table. Amount of
