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.
