| Mitering - |
 Mitering is a basic operation in which an angle is cut across the moulding using a miter box or an electric miter saw. Inside and outside corners and moulding around windows and doors are usually cut at a 45 degree angle. |
| Coping - |
 This technique is used when butting one moulding against the profile of another. First, set the moulding in the miter box as it is to be installed on the wall, upright against the back plate. Cut the end of the moulding at a 45 degree angle. This cut exposes the profile of the moulding. Following the profile, cut with a coping saw at a 90 degree angle with the face of the moulding. This results in a duplication of the profile pattern which fits over the face of the adjoining moulding. |
| Splicing - |
 In order to install moulding over large spans, you may have to splice two lengths of moulding together. The moulding is spliced with a vertical seam by placing the two pieces of moulding in a miter box as they will lay and mitering them at a 45 degree angle. Gluing the joint before nailing the moulding into place will strengthen the joint. |
