Planer Table
Parallelism
Table parallelism is critical to the operation of the
machine. As such, it is essential that the table is
parallel with the cutterhead (within 0.003") from
side-to-side, as illustrated in Figure 80.
Maximum Allowable Tolerances:
Cutterhead to Table Side-to-Side ..............0.003"
Headstock to Table Front/Back .................0.040"
Tools Needed: Qty
Rotacator ........................................................... 1
Standard Screwdriver ........................................ 1
Wrench or Sockets 13mm ................................. 2
Hex Wrench 5mm .............................................. 1
Sawhorses ......................................................... 2
Assistant ............................................................ 1
Forklift ................................................................ 1
White Marker or Correction Fluid .............. Varies

How the table sits in relation to the base from
front-to-back is also important (see Figure 81).
The tolerances on the front-to-back positioning
are not as critical as the cutterhead/table side-to-
side positioning. Therefore, the maximum allow-
able tolerance for the front-to-back parallelism is
not more than 0.040".
Table Parallelism Inspection
The easiest way to determine if your planer table
has a parallelism problem with the base 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 31) to further inspect
the table parallelism, as shown in Figure 82 and
Figure 83 on Page 50.
To inspect the cutterhead-table parallelism:
1. Place the jointer outfeeed table in the upright
position, then rotate the dust chute assembly
up and over the cutterhead to access the
cutterhead and planer table below.
