CHATTER
Snipe
De fi ni on
Cha er marks are irregulari es in the fi nish quality of the
surface of the wood. They can be evenly spaced or ran ‐
domly distributed. Simply put, they may be described as
“hills and valleys” in the wood surface.
Cause
These marks are caused by either loosely held stock or by
an imbalance in the machine’s mechanical quali es
Solu ons
The most common cause of poor stock fi nish
quality is a rough running belt. Replace the
belt.
Make sure you are cu ng with the head set
at the appropriate height.
Keep your knives sharp. Dull knives cause
intermi ent feeding.
Check the pulleys for damage or imbalance.
Check to see that both knives and all a ach ‐
ing bolts are of the same weight.
De fi ni on
Snipe is generally an unwanted undercut in the
stock. It occurs in the fi rst and last few inches of
the stock length. It causes a di ff erent height di ‐
mension than what was selected for the stock.
Causes
The stock may be cupped, warped or twisted.
The stock experiences a change in down pressure
as the out feed roller engages the stock, and when
the stock disengages with the in feed roller.
The stock may enter or exit the machine on an
angle because it is either being fed from a higher
or lower plane than the bed, or it is exi ng to a
higher or lower plane.
Solu ons
Use a jointer to fl a en cupped, warped, or twisted
stock.
Bu stock pieces ght end to end.
Put a slight upward pressure on the exposed end
of the stock during both the in feed and out feed
stroke.
Use slightly longer stock length than needed and
cut the snipe o ff .
Make sure the head locking handle is ght.
Your outboard support should be slightly higher
than your bed.
