How to Cope an Inside Corner with a Coping Saw Video

A Coping Saw is the Ideal Tool for Making Perfect Inside Corners when Installing Baseboard Trim or Molding

By Mark J. Donovan




In this video, Mark Donovan of HomeAdditionPlus.com shows how to cope an inside corner when installing baseboard trim, and using a miter saw and coping saw.

Most inside corners are not perfectly 90 degrees. Consequently if you simply cut two pieces of baseboard trim at 45 degree angles and expect to get a perfect inside joint you’re going to be sadly disappointed.

Fortunately there is a way to get that perfect inside corner using a a miter saw and a coping saw.

Simply nail into place one piece of baseboard trim up against one of the walls. The end of the board should be be square cut and butt up into the adjacent wall.

Next, cut one end of a second piece of baseboard trim at a 45 degree open faced angle.

Then using your coping saw, back cut at a 45 degree angle the piece of baseboard trim along the paint/prime line.

After making the coped cut, place the trim board into place up against the adjacent wall. You should observe that by making this type of coping cut you will have created the perfect 90 degree inside corner.
