Precision Fence
The PJ-882HH 8"
Parallelogram Jointer comes
with a fully adjustable fence
system that makes high
precision bevel cuts easy to
do. The 38 3/16”-long by 4
¾”-tall cast iron fence is
supported by large iron
components that assure
stability and truly accurate
cuts at any angle. The fence
even has a special non-mar insert that allows it to glide over the cast iron table smoothly without
leaving annoying scratches.
The fence has an insert (left) that prevents scratching the table when it is moved. The
operating mechanism (right) allows precise bevel setting and a very stable fence when
locked.
The fence has adjustable stops at 90-degrees (vertical) and 45-degrees in or out. Changing fence
angles is made especially precise by a rack and pinion gear drive system operated by a 3 ¾”-
diameter cast iron handwheel fitted with a spinner handle. A large lever locks the fence at any
bevel angle desired. Of course, the fence can be positioned at any point across the width of the
tables and is locked with a separate handle.
A handy scale on the fence mechanism indicates the bevel angle. A magnified lens over the scale
makes reading it easier.
Knife Cutterhead
The PJ-882 (#1610079) is equipped
with our controlled chip three knife
cutterhead. To make aligning the
knives easy we use a jack screw
system that allows making tiny
adjustments to knife height simple
and predictable. Each knife has two
jack screws, one on either end to
make setting its overall height and
getting it parallel to the table
surface easy. We even include an easy to use knife setting block to make the alignment process
faster and easier.
Our controlled chip, three knife cutterhead feature jack screws (arrow, left
photo) that make setting precise knife heights very easy. We also include a
simple knife-setting jig (right). When the knife is at the correct height, if the
first arrow is placed at the end of the outfeed table and the knife rotated
under the jig, the jig should move so the second mark is at the edge of the
outfeed table.
Having the knives aligned perfectly is crucial to the quality and accuracy of the cut and the
longevity of the cutting edge. When the knives are all set correctly, wear is distributed evenly
over all three, drastically slowing the rate at which the cutting edge dulls.
