How to Cut Mitered Corners with a Miter Box

Hello! Hello! Today we are talking about the Miter Box again! Last time we showed you how to simply cut straight cuts with the Miter Box. Hopefully we built up your confidence and you are no longer scared to death of the blade! Today we are going to show you How to Cut Mitered Corners with a Miter Box. This is probably what we use the Miter Box for the most. We use it for baseboards, frames, tables, signs – anything we want a nice corner on.

The Miter Box can cut any angle from 0-50 degrees – but the MOST common angles are the 22.5 degree and the 45 degree angle.


To show the miter box in action here is The Contractor in a little video we made!

And in case you cannot see the video – here is a tutorial!

How to cut Mitered Corners with the Miter Box

  • Keep your compound angle set to 0 degrees
  • Move your fence to your desired degree. (we are cutting a 45 degree angle.)

You can cut flat or cut on edge –

  • To cut flat, lay your wood flat down against the bottom of the saw.
  • Hold your piece of wood tight to the fence.
  • Bring your wood to the spot where you have measured to cut.
  • Make sure your hands are out of the way of the blade!
  • Bring the blade down to make sure the blade will cut where you want it too.

  • Lift the blade up and slowly start the motor by pushing it with your fingers.
  • Move the blade through the wood at a nice even pace.

  • Bring the blade back up and hold onto your wood until the blade/motor stops.
  • You will have a nice 45 degree angle.

  • Cut the same angle twice and you will have a nice 90 degree angle.

To cut on edge- follow the same steps as above – cutting on the edge side instead.


NOTE: When you are cutting a project that will be facing up (face up/out) you will need to change your fence from right angles to left angles. In the tutorial we were cutting plain ole’ 2x4s so we weren’t worried about anything facing up. Sometimes for baseboards or framework with designs on the face you will need to cut the wood laying flat and have the design face up. One end would need to be cut with a left side 45 and one with a right side 45. Make Sense?? We will get more in-depth with some project tutorials later on. Have fun with your fancy new corners!
