CUTTING CROWN MOULDINGS
1.There are several methods that can be used to cut crown mouldings on the miter saw. The method shown in Fig. 35, illustrates the contact surfaces (the surfaces that contact the wall and ceiling) of the crown moulding held firmly against the fence and table of the miter saw. This method is acceptable when making a small number of cuts but would not be practical for a production appli- cation as it may be difficult to firmly hold the work in this position. Also, this method means that the crown moulding must be positioned on the table in the upside down position.
2.When a large number of repetitive cuts of crown moulding are required we suggest the use of filler blocks, as shown in Fig. 36 through Fig. 39. The majori- ty of crown mouldings have contact surfaces at 52 and
38degrees to the rear surface of the moulding and these angles must be utilized when jointing the face of the filler block. For crown mouldings with different angles, appro- priate filler blocks can be produced.
3.Fig. 36 and Fig. 37, illustrate the filler block fastened to the miter saw fence with the face of the filler block extending outward from the top of the fence and down to the surface of the table. When the filler block is posi- tioned in this manner, the crown moulding must be posi- tioned on the table in the upside down position. This means that the surface of moulding that contacts the ceiling is against the table.

4.Fig. 38 and Fig. 39, illustrate the filler block fastened to the miter saw fence with the face of the filler block extending inward toward the fence from the top to the bottom. When the filler block is positioned in this man- ner, the crown moulding is placed on the table in the same position as it would be when nailed between the ceiling and wall.
