Rabbeting
A rabbet cut requires
removal of the cutter guard. Use extreme
caution and keep hands clear of cutterhead.
Always replace guard immediately after
rabbeting operation is completed.
Refer to Figure 37.
A rabbet is a groove cut along the edge of a
board. Never rabbet a piece of wood less than
12" long. Use push blocks to rabbet cut
whenever possible.
1. Disconnect machine from power source.
2. Set fence for the desired width of the rabbet.
3. Check the width of the rabbet by measuring
the distance from the end of a knife in the
cutterhead to the fence. (See figure 17 to
set knives for rabbeting.)
4. Lower infeed table 1/32" at a time and make
successive cuts until the desired depth of
rabbet has been obtained. NOTE: It is
easier and safer to take a series of shallow
cuts.
When rabbeting long pieces, follow the same
procedure as for surfacing long pieces (refer to
previous “Surfacing” section.)
Maintenance
Disconnect machine from
power source before doing any maintenance.
The table and fence surfaces must be kept
clean and free of rust for best results. Some
users prefer a light coat of paste wax. Another
option is talcum powder applied with a
blackboard eraser rubbed in vigorously once a
week, which will fill casting pores and form a
moisture barrier. Products in aerosol form are
also available in major hardware stores and
supply catalogs. Whatever method is chosen,
the coating should protect the metal and provide
a smooth surface, without staining the wood.
The fence assembly should slide easily over the
fence support. Keep the fence support greased.
The bearings in the cutterhead are sealed and
do not require lubrication.
Gum and pitch which collect on the knives
cause excessive friction as the work continues,
resulting in overheating of the knives, less
efficient cutting, and consequent reduction in the
life of the knives. Use an oven cleaner or gum
and pitch remover to wipe such residue off the
knives.
