| |
Mark out and cut one half of a half lap joint (Dia. A ).
Place it on top of a second piece of wood, ensuring that it is in the centre (Dia. B). Use a marking knife to mark its width.
Now use a marking knife, to mark / draw the two ‘width lines’ across the top surface. Rotate the wood and continue the lines half way down each side (Dia. C) |
| |
 |
| |
|
|
| |
| Set a marking gauge to half the width of the wood (Dia. D). Use the gauge to mark the lines, along each side (Dia. E), clearly showing the waste wood. At this stage it may be wise to use a sharp pencil, to enhance the marking knife lines. Also, shade the waste wood, so that it is clearly seen. |
| |
 |
| |
Secure the wood in a vice. Saw down each side of the joint, cutting on the waste wood side of the lines (Dia. F).
A bench hook can be used for this procedure, but it is more difficult to control the wood and saw. |

| Secure the wood in the vice. Use a bevel edged chisel to slowly remove the waste material. |
| |
 |
| |
| At this stage the sides of the joint will be rough, due to the action of the saw blade. The chisel’s sharp edge should be lodged in marking out line on the top surface. Carefully ‘tap’ the chisel with a mallet, removing the final waste wood. This will ensure the sides are accurately cut (Dia. H). |
