Adjusting Jointer Table Parallelism
For safe and proper cutting results, the tables
must be parallel to the cutterhead. Adjusting them
to be parallel is a task of precision and patience,
and may take up to one hour to complete. Luckily,
this is considered a permanent adjustment and
should not need to be repeated for the life of the
machine.
Due to the complex nature of this task, we rec
-
ommend that you double check the current table
positions to make sure that they really need to be
adjusted before starting.
You can adjust stop bolts on the front of the tables
and shim under the back of the tables to adjust
them parallel to the cutterhead.
The correct order for adjusting the table parallel
-
ism is to first adjust the outfeed table parallel with
the cutterhead, then adjust the infeed table paral
-
lel with the outfeed table.
To adjust the jointer table parallelism:
1. Perform the "Checking/Adjusting Table
Parallelism" procedure on
Page 39, including
making any necessary adjustments so the
cutterhead and outfeed table are parallel.
2. Place the straightedge halfway across the
infeed table and halfway over the outfeed
table, and adjust the infeed table even with
the outfeed table, as shown in
Figure 55.
3. Place the straightedge in one of the positions
shown in
Figure 56.
5. While an assistant raises the infeed table,
slip shims between the hinged shaft and the
jointer base, then retighten the cap screw.
Shimming the top position will raise the rear
cutterhead side of the table, shimming the
lower position will raise the rear infeed side.
6. Repeat Step 3 with each of the remaining
straightedge positions and adjust the table
front to back using the shims as many times
as necessary until the infeed table is parallel
with the outfeed table.
7. Set the knives (refer to Page 43).
8. Reinstall the cutterhead guard.
—If the front of the infeed table is higher or
lower than the outfeed table, adjust the
infeed table stop bolts (see
Correcting
Infeed Table to Cutterhead Parallelism
on Page 40).
—If the rear of the infeed table is higher or
lower than the outfeed table, shim the
infeed table to adjust it parallel with the
outfeed table. Follow Steps 4-6
.
4. Loosen the cap screws shown in Figure 57.
