the operator from pushing down directly over the cutter, something you shouldn’t be
doing anyway. For edge jointing operations, the guard is adjusted to allow the material to
pass between its end and the fence. Here again, the unused cutter remains covered
throughout the operation.
The bridge style cutter guard is needed only for jointing operations. The guard remains in
place without modification when the jointing table is rotated up to convert to the planer
mode.
Planer Mode
The JET JJP-12 Jointer-Planer is a fully capable thickness planer
with a 12”-cut width and handles a whopping 8 ¾” maximum
material thickness. The maximum full-width cut depth is 1/8”
with 5/32” being the maximum cut on narrower stock. Naturally,
lighter cuts put less stress on the wood itself and often produce
much better results. The 5500 RPM cutterhead speed means a
constant 20 FPM feed rate is a good balance between quick
material removal and a clean, smooth surface.
In the planer mode the JJP-
12 handles boards up to
12” wide with power to
spare.
In planer mode the material feed roller system is engaged by
moving an exterior handle to the On position. That produces a
material feed rate of 20 FPM. (feet per minute) The control lever
is moved to the Off position when the JET JJP-12 Jointer-Planer
is changed to the jointing mode.
The cutterhead assembly is fixed and includes a row of gravity-operated anti-kickback
fingers for safety. A serrated metal feed roller is designed to resist contamination and
maintain a consistent material feed rate for the best results. A rubber-covered outfeed
roller keeps the stock moving without marring the freshly planed surface.
The 21 ¼” by 12” planer table adjusts up and down through a large handwheel (with
spinner handle) on the infeed end of the JET JJP-12 Jointer-Planer while in planer mode.
A scale on the handwheel hub shows the amount of change partial turns create while a
full height scale with pointer shows overall cutter to table distance. The planer table is
locked with a lever-type handle.
The JET JJP-12 Jointer-Planer was designed to bring the much needed jointing and
planing capabilities to your shop in a single, space-saving 55”-long by 39 ½”-tall (top of
fence) and 32”-deep (fence at its widest setting) package. Because of its space saving
design and our focus on accuracy, function and durability, the JET JJP-12 Jointer-Planer
is as economical as it is versatile.
