How to Mitre the Plinth

In this video, I show you how to accurately mitre and attach the plinth to achieve a perfect, seamless fit. I do this by constructing a 45 degree shooting board using scrap material and a sliding bevel set to a 1:1 ratio. It may sound complicated, but I explain everything thoroughly in this video.

This lessons objectives:

  • Methods of cutting the mitres
  • How to layout a perfect 45 degree
  • How to make a 45 degree shooting board
  • How to extend mitres that were cut short

Other methods you may consider using are a disk/belt sander with a 45 degree mitre gauge, or alternatively a mitre saw. These methods are fine however you need to be a lot more careful compared to a shooting board.

Using a shooting board will mean you're consistently taking off the same amount of material with each pass, meaning its very easy to sneak up to a precise final fit. A sander or mitre saw however will take off different amounts of material depending on how much pressure you apply, the density of the wood, the speed of the sander, or simply the alignment under the mitre saw. Of all the methods, I would highly recommend constructing the shooting board as demonstrated in this video.
