Table parallelism is critical to the operation of the
planer. As such, it is essential that the planer table
is parallel with the cutterhead (within 0.002")
from
side-to-side, as illustrated in
Figure 75.
Figure 76. Front-to-back parallelism.
Figure 75. Side-to-side parallelism of table and
cutterhead.
How the planer table sits in relation to the head
casting from front-to-back is also important (see
Figure 76). The tolerances on the front-to-back
positioning are not as critical as the cutterhead/
table side-to-side positioning. Therefore, the max-
imum allowable tolerance for the front-to-back
parallelism is not more than 0.020".
Table Parallelism Inspection
The easiest way to determine if your planer table
has a parallelism problem with the headstock is to
plane a workpiece and measure the thickness in
multiple locations. If the workpiece is tapered from
left-to-right or from front-to-back, then parallelism
may be a problem
.
Use your Rotacator
(Page 32) to further inspect
the
table parallelism. If you do not have a
Rotacator, a wood block and feeler gauges may
be used, but extra care must be taken to ensure
accuracy. If the table is not within the maximum
allowable tolerances, it must be adjusted.
Table Parallelism Adjustments
The table is adjusted with the set screws on the
cylinder liner.
To adjust the table parallelism:
1. DISCONNECT THE JOINTER/PLANER
FROM THE POWER SOURCE!
2. Raise the planer table as far as possible.
