Figure 27. Recommended bed roller height above the
table surface.
The correct height of the bed rollers will vary,
depending on the type of material you intend to
plane. However, as a general rule, keep the bed
roller height range within the listed range above
the table surface, as illustrated.
When planing rough stock, set the rollers high
to keep the lumber from dragging along the bed.
When planing milled lumber, set the rollers low
to help minimize snipe.
To ensure accurate results and make the
adjustment process quicker and easier,
we recommend using a Rotacator (refer to
Accessories) to gauge the bed roller height from
the table surface. If a Rotacator is not available,
a straightedge and feeler gauges can be used, but
care must be taken to achieve accurate results.
Bed rollers that are not adjusted to the correct
height or out of alignment with each other
can cause poor finishes, inconsistent planing
thickness, and other undesirable results.
