What Does a Mortiser Do?
A mortiser is a specialized woodworking machine used to create mortises, which are square or rectangular holes in wood designed for mortise and tenon joints. This joint type is one of the most reliable methods for joining two pieces of wood, commonly used in furniture making, door frames, and cabinetry. The mortiser makes clean, precise cuts that are difficult to achieve with hand tools or other machinery, providing strength and durability to the joint.
How to Use Mortice Drills?
Using a mortice drill involves attaching a mortising bit and chisel to the machine. The bit spins to remove wood while the chisel shapes the sides into a square. Follow these steps to use a mortice drill effectively:
- Secure the Workpiece: Clamp the wood securely to prevent movement during drilling.
- Align the Mortiser: Position the bit and chisel where the mortise is to be cut.
- Drill in Stages: Lower the bit into the wood, working incrementally to ensure even cuts. Remove excess wood gradually and don’t force the tool.
- Clean the Mortise: After drilling, remove any remaining wood with a chisel if necessary to refine the edges.
How Does a Mortising Bit Work?
A mortising bit works by combining a rotating bit inside a square or rectangular chisel. The drill bit removes the bulk of the material from the mortise, while the sharp chisel edges cut the sides of the hole to a precise shape. The bit spins to remove material, while the chisel remains stationary, ensuring that the mortise is clean, with square corners. This dual-action makes mortising bits more efficient than regular drill bits, particularly for making mortise and tenon joints.
How to Use a Morticer Machine?
Using a morticer machine is relatively straightforward:
- Set Up the Machine: Secure the correct mortising bit and chisel in the machine. Adjust the depth stop to the desired mortise depth.
- Mark the Mortise Area: On your workpiece, mark the position and dimensions of the mortise using a pencil or chalk.
- Position the Workpiece: Place your wood under the mortiser, ensuring it’s properly clamped down for stability.
- Begin Mortising: Lower the bit and chisel by applying pressure on the lever, drilling out the mortise in stages. Move along the marked area until the full mortise is cut.
Finishing: Once the mortise is complete, you may need to clean up the edges or bottom with a hand chisel to ensure accuracy.
