Adjusting Feed Roller
Spring Tension
The infeed and outfeed rollers keep the
workpiece moving through the planer. Springs
exert downward pressure on the feed rollers
while allowing them to raise with an uneven
workpiece surface. Proper spring tension is
crucial to keep the workpiece moving through the
planer during operation without pulling from one
side to the other.
The amount of tension on the infeed roller needs
to be enough to push the workpiece into the
cutterhead but not enough to gouge or bind the
workpiece.
The amount of tension on the outfeed rollers
needs to be enough to pull the workpiece along
the planing path without binding and prevent
snipe at the end of the workpiece. The ideal feed-
roller spring tension varies depending upon the
type of wood you plane. When adjusting spring
tension, keep the following in mind:
• If you are planing milled lumber with a
consistent surface, use less spring tension to
reduce the risk of marring the workpiece.
• If you are planing rough lumber with
inconsistent surfaces, use greater spring
tension to keep the stock moving through the
planer.
• If the workpiece consistently stops feeding
during operation, the spring tension may
need to be increased.
