5. Halving Joint
Halving joint There are many versions of the halving joint but they all involve removing half of the wood from each piece using a saw or a chisel. This joint is often strengthened with dowel.

6. Mitre Joint vs. Halving Joint
On your bench discuss which is better, Mitre joint or Lap Joint. Each bench will provide one possible answer. Here’s one clue.

7. What are the benefits of a Halving Joint?
The larger gluing surface means a halving joint is stronger that a mitre joint, and is often used to make a corner stronger. Are there other benefits? Lets make one.

9. Halving Joint step 1
Tri square for marking right angles

10. Halving Joint step 2

11. Halving Joint step 3
Use the marking gauge to draw a parallel line.

12. Halving Joint step 4
Shade in the area you are going to remove. This is called the waste.
