Cutting Miter Joints in Crown Molding Between Two Walls

Video Demonstration


First, measure the distance between your walls (2 and 3 on Fig. 7). Then cut the crown molding with a square cut at 90 degrees to fit tight between the walls.

Use the Template to set the workpiece holders at the required A internal angle (Fig 7) for your miter joint. Then cut two short test pieces and when you are satisfied they fit together properly you can proceed to the next stage.

Cutting crown molding to fit between two walls

Place the piece of crown molding for wall 1 (with its 'wall edge' to the back) in the left-hand workpiece holder and cut your mitre cut at the very end of your workpiece for corner A.

With the workpiece holders still set for corner A, select the piece of crown molding that you intend to fit to Wall 2 and, with its 'wall edge' to the back, place it in the right-hand workpiece holder and cut your miter at the very end of the workpiece for corner A. Place it to one side.

Cut the miter joint for Angle B

Once again using the Template set the workpiece holders to the required B internal angle and proceed by cutting test pieces. When satisfied, place your workpiece for Wall 1 in the right-hand workpiece holder and cut your miter joint starting at the very end of your workpiece.

Your workpiece for Wall 1 will now be ready for fitting. But before proceeding any further, and prior to changing the corner B setting of the workpiece holders, select your piece of crown molding that you intend to fit to Wall 3 and, with its 'wall edge' to the back, place it in the left-hand workpiece holder and cut your miter joint at the very end of the workpiece for corner B.
