YOU WILL WORK IN PAIRS FOR THIS TASK
Person 1: Completes the cross-halving joint
Person 2: Completes the dowel joint
Time: 60 minutes
WOOD JOINT #1: THE CROSS HALVING JOINT
One of many wood joints you could utilise in this project, we will practice the cross-halving joint.
A cross halving joint is a woodworking joint where two pieces of timber are notched halfway through their thickness so they can intersect and sit flush at right angles (or sometimes at other angles).
Marking out: Both pieces are measured so that the width of the notch matches the width of the other piece.
Cutting the notch: Material is removed to a depth equal to half the timber’s thickness.
Assembly: The two notched pieces slide together so their surfaces are flush.
Frames – e.g. trellises, workbenches, wooden frames, lattice structures.
Furniture – especially in table bases, shelving frames, and bed supports.
Timber structures – like partition walls or display stands.
Garden constructions – planters, fence frames, compost bin frames.
How to Create a Cross-Halving Joint.
This video will take you through each step. The steps shown below this will also help as they are specific to this task.
Tools you will need:
Steps.
Note: Next, you may need to refine your cuts to ensure a flush fit. You can do this by removing a little more material with either the chisel, saw or a file.
You would glue together with wood glue to secure permanently.
WOOD JOINT #2: THE DOWEL JOINT
One of many wood joints you could utilise in this project, we will practice the dowel joint.
A dowel joint is a woodworking joint where wooden dowels (small, cylindrical rods) are used to align and hold two pieces of wood together. It’s essentially a way of creating an invisible mechanical fastener made from wood.
Marking and alignment: The positions for the dowels are marked on both pieces of wood so the holes line up perfectly.
Drilling holes: Holes are drilled to match the dowel diameter, usually slightly deeper than half the dowel’s length in each piece.
Inserting dowels: Wooden dowels are glued into the holes.
Assembly: The second piece is fitted over the exposed dowel ends with glue, making the joint strong and precise.
Cabinet frames – for aligning and joining face frames.
Tabletops – joining planks edge-to-edge.
Chairs and stools – connecting legs to rails without metal fasteners.
Shelves and bookcases – fixing shelves to side panels.
Flat-pack furniture – widely used in IKEA-style assembly for easy alignment

ONCE FINISHED, DISCUSS AND COMPARE WITH YOUR PARTNER
