SYMPTOM
Chipping occurs on workpiece.
Grain is fuzzy after jointing.
Lines or ridges in workpiece.
Uneven blade marks on work-
piece.
Wavy surface or chatter marks on
workpiece.
Edge is concave or convex after
edge jointing.
POSSIBLE REASON
1. Grain direction incorrect or knots in
workpiece.
2. Dull blades.
3. Too fast of a feed rate.
4. Too deep of cut.
1. Wood may have high moisture con-
tent. Check with moisture meter.
2. Dull blades.
3. Wood is figured or is a species that
has naturally fuzzy characteristics.
1. Nicked or chipped blades.
1. One or more cutterhead blades are
worn.
1. Too fast of a feed rate.
2. One or more cutterhead blades are
worn.
1. Workpiece not held with even pres-
sure on infeed and outfeed table.
2. Workpiece began too uneven.
3. Workpiece has excessive bow or
twist along its length.
4. Insufficient number of passes.
5. Outfeed table not properly aligned
with cutterhead.
HOW TO REMEDY
1. Feed workpiece with the grain. Inspect workpiece for
knots or try again with different workpiece.
2. Replace blades.
3. Feed the workpiece at a slower rate.
4. Decrease depth of cut.
1. Allow wood to dry.
2. Replace blades.
3. Use different wood or plan on extra sanding.
1. Inspect blades. Replace if necessary.
1. Inspect blades. Replace if necessary.
1. Feed the workpiece at a slower rate.
2. Inspect blades. Replace if necessary.
1. Hold workpiece with even pressure as it moves through
the cutterhead. See “Edge Jointing” on page 24.
2. Take partial cuts to remove extreme high spots before
doing a full pass.
3. Surface plane one face so there is a good surface to posi-
tion against the fence.
4. Three to five passes may be needed to achieve a perfect
edge, depending on starting condition and depth of cut.
5. Set outfeed table even with cutterhead blade at top dead
center. See page 18-19.
