BEVELING
To cut a bevel, lock the fence at the required angle and run the
work across the knives while keeping it firmly against the fence and
tables. Several passes may be necessary to arrive at the desired
result.
TAPER CUTS
One of the most useful jointer operations is cutting an edge to a
taper. The method can be used on a wide variety of work. Tapered
legs of furniture are a common example.
Instead of laying the piece on the infeed table, lower the forward
end of the work onto the outfeed table. Do this very carefully, as
the piece will span the knives, and they will take a "bite" from the
work with tendency to kick back unless the piece is firmly held.
Now push the work forward as in ordinary jointing the effect is to
plane off all the stock in front of knives to increase depth, leaving a
tapered surface.
The ridge left by the knives when starting the taper may be remove-
d by taking a very light cut according to the regular method for
jointing, with the infeed table raised to its usual position.
Practice is required in this operation, and the beginner is advised to
make trail cuts on waste material. Taper cuts over part of the length
and a number of other special operations can easily be done by the
experienced craftsman.
MAINTENANCE
△
!
CAUTION: DISCONNECT MACHINE FROM POWER SOURCE
BEFORE PERFROMING MAINTENANCE.
Check all screws and fasteners occasionally and keep them tighten
securely.
In time, rust may appear on the table and fence and other parts of
the jointer, resulting in less efficiency and accuracy of the machine,
use paste wax which can be applied to prevent rust formation. If
however, rust has already formed on those parts, use "Rust
Remover" which will restore the machine to its original accuracy.
LUBRICATION
Use a good grade of light grease on the steel adjusting screws for
the raising and lowering mechanisms of the infeed and outfeed
work tables.
The cutterhead runs in two single-row sealed and shielded ball
bearings, which are pre-lubricated for their entire life.
WHETTING KNIVES
1. Disconnect the machine from power source.
2. Use a fine carborundum stone. Cover it partly with paper as
shown Fig. 15, to avoid marking the table.
3. Lay the stone on the infeed table, lower the table and turn the
cutterhead forward until the stone lies flat on the bevel of the
knife.
Fig. 15
4. Hold the cutterhead from turning, and whet the beveled edge
of the knife, stroking lengthwise by sliding the stone back
and forth across the table. Do the same amount of whetting
on each of the three blades.
5. When finished, reset the knives parallel to the outfeed table
(see "Setting Knives & Outfeed table")
CUTTERHEAD REPAIRES
The entire cutterhead assembly may be removed for cleaning,
bearing or blade replacement or any other cutterhead maintenance
procedures. To remove it, lower both feed tables to clear the
cutterhead. Remove the bearing,retaining stud and then the entire
cutterhead assembly with bearings, studs and bearing housings (see
exploded view pg. 16). Before reinstalling the assembly, be sure the
machine’s curved seated of the base casting are free of dirt, dust
grease, etc. to obtain a good tight fit.
BLADE CARE
When blade become dull enough so that it is noticeable when
cutting, they should be resharpened a sharp blade works easier and
dull blade is less blade life and greater wear and tear on all parts of
the machine.
When the knife cannot be properly re-touched as described in
"Whetting Knives" they must be ground and re-surfaced to a new
bevel edge. Check in the "Yellow Pages" of your local phone
directory under "Sharpening Service" or "Tool Grinding or
sharpening". It may be less expensive to purchase a new set of
blade.
Gum and Pitch which collects on the blades causes excessive
friction as the work continues, resulting in over heating the blade
life. Use"Gum and Pitch Remover" to wipe off the blades.
