OPERATION

MAKING A CROWN MOLDING SUPPORT JIG

See Figure 46.

A  crown  molding  support  jig  will  need  to  be  made  when 
cutting crown molding with no required bevel setting. The 
support  jig  holds  the  crown  molding  in  place  during  the 
cutting  operation.  When  using  this  method,  the  saw  can 
be  quickly  adjusted  for  corners  that  are  not  90

°

  square.

NOTE:

 A separate support jig must be made for different 

widths.

To make a support jig:

  Using a piece of wood 1/2 in. thick, 4-1/4 in. high, and 

23 in. long, place the wood on the miter table against the 
miter fence.

  From the back side of the saw, use a pencil to mark the 

wood through the holes in the miter fences.

  Drill holes through the wood then countersink the holes 

to accept flat head screws.

  Attach  the  wood  to  the  fence  using  the  flat  head 

screws.

  Place a piece of crown molding firmly against the miter 

table and the wood. Mark the height of the molding with 
a pencil.

   Remove the screws and the wood from the miter fence 

then cut the wood to this width.

  Using  small  nails  and  glue,  attach  a  piece  of  wood  

(1/2 in. thick x 1-1/2 in. wide x 23-1/2 or 28 in. long) to 
the top of the wood.

 

NOTE:

 Keep nails away from the area around the blade 

cutting path.

  Securely reattach the support jig to the miter fence.

  Make a full 45° left miter cut and a 45° right miter cut 

through the completed support jig.

USING A CROWN MOLDING SUPPORT JIG

  Place the crown molding upside down on the miter table 

with the bottom of the molding against the wood fence.

  Use the chart on this and the previous page to select the 

proper miter angle.

  Lift the miter lock lever and position the miter table to 

the desired setting. Push the miter lock lever down to 
securely tighten the miter table.

  Make sure the slide lock knob is tightened securely.

  Slowly lower the blade into and through the molding.

  Release the switch trigger and allow the saw blade to 

stop rotating before raising the blade out of workpiece 
and removing the workpiece from the miter table.
