Powermatic PJ-882HH manual Parallelogram Tables, Table Heights

substantial amount of chips and dust that the PJ-882HH 8" Parallelogram Jointer is capable of creating.

Parallelogram Tables

For a jointer to straighten wood accurately the infeed and outfeed tables must be coplanar - perfectly aligned with each other side-to-side and front-to-back. The tables on the PJ- 882HH 8" Parallelogram Jointer have been accurately aligned at the factory but they could possibly need adjustment in the future. To make those once complicated adjustments much easier we built in special cams, two on the front and two on the rear of each table. These cams allow the user to correct this alignment should that become necessary and do it quickly saving time and money.

Each corner of the infeed and outfeed

tables has an adjustable cam for

correcting coplanar misalignments. The

outboard cams on the front of the machine are under the height levers.

The mechanism that moves the tables up and down also keeps them close to the cutterhead throughout their range of travel. Keeping the tables close to the cutterhead produces cleaner, more accurate cuts and a superior finish on the wood.

Table Heights

Both tables use levers to adjust their heights. The infeed table lever is augmented by an automatic depth limiter that can be released for deep cuts with the twist of a small knob.

The outfeed table is fitted with limiting stops that control the full up and full down travel. A lever moves the outfeed table up and down and another lever locks it in place. Rabbets up to ½” by ½” can be cut on the PJ-882 8" Parallelogram Jointer. Note: Rabbets cannot be cut with the models equipped with the helical cutterhead.

The infeed table also has an easy to use lever for locking it in position. However, a much longer lever makes adjusting the height of the massive table to set cut depth (up to ½”-maximum) exceptionally accurate.

A handy depth stop knob automatically limits cut depth to 1/8”. To increase cut depth simply pull that knob out, rotate it 90-degrees and the infeed table can be set to make cuts up to ½” deep. A scale on the side of the infeed table makes it easy to set the exact cut depth you want.
