How to cut crown molding inside corners?

Published in Crown Molding Installation 3 mins read

To cut crown molding for inside corners, you need to make precise cuts on two pieces of molding that will meet in the corner. Based on the provided information, making the right side miter cut for an inside corner involves specific saw positioning and molding placement.

Preparing for the Cut

When cutting crown molding, it's essential to position the molding on the miter saw correctly to mimic its installed position on the wall. This typically means placing the molding upside down and backward against the saw's fence and base. The edge of the molding that rests on the wall will be flat on the saw's base, and the edge that rests on the ceiling will be held against the saw's fence. This orientation ensures the bevel cuts are made at the correct angle relative to the wall and ceiling planes.

Making the Right Side Inside Corner Cut

For an inside corner where a piece of molding comes from the right and meets a piece coming from the left, you need to cut the right-side piece. According to the provided reference:

  • Position the Saw: Set your miter saw's blade angle adjustment to the right at a 45-degree miter angle.
  • Hold the Molding: Position your molding piece on the saw. The reference mentions holding "our molding up into place." This refers to securing the molding in the standard cutting position (upside down and backward) against the saw's fence and bed. Ensure it is held firmly and correctly to avoid movement during the cut.
  • Make the Cut: With the saw set correctly and the molding held securely, make the miter cut.

This cut creates the necessary angle on the right-hand piece of molding to fit into the inside corner, typically meeting a corresponding cut piece from the left.

Key Steps for Right-Side Cut:

  1. Set miter saw angle: 45 degrees to the right.
  2. Position molding: Upside down and backward, securely against fence and bed.
  3. Cut the molding.

Note: This information details the setup and cut for one side of a typical 90-degree inside corner (the right side) using a miter cut as described in the reference.
