"DUPLEX" HINGES
You can use the 557 to make the mortises required for installing "duplex"
hinges. Make a spacer and attach it to the 557 fence. The spacer can be made
3
of scrap / " wood. Cut the spacer to approximately 3-
4
to the fence with two 3 / " wood screws (see Fig. 18A).

#6 BISCUITS
With the 4" blade installed, set the depth adjusting turret to the MAX position.
Two cuts will be required to produce each groove for a #6 biscuit. Space the
centerlines of these two cuts
first cut centerline, move over
POSITIONING GROOVES
The number of grooves (biscuits) used in a joint may be varied to provide the
strength required for the particular application. Typically position the center
of the first groove approximately 2" from the edge of the work with additional
grooves spaced at 3" to 6" on centers.
In most cases use one line of grooves (biscuits) positioned approximately along
the centerline of the material. On thicker material use an additional row(s) of
biscuits for added strength.
Position the two workpieces (to be joined) in the relationship desired after
joining. Mark the centerline of each groove required as shown in Fig. 19A-D.
Use a square to assure accuracy.
