Makita 7104L/2 240V Chain Mortiser

Product Information

Precision comes from taking your time and setting up the machine carefully. Remember the woodworker’s adage: Measure twice, cut once. How a mortiser works Benchtop mortiser The square sides of the chisel then remove the rest, so with one plunge motion you make a perfectly square hole.

As with all woodworking machines, the more rigid it is, the more repeatable accuracy you’ll have. It should also be more durable. A mortiser won’t work effectively when the bit and chisel are dull, so keep both parts sharpened. No need for a lot of tools, just a chainsaw file, a round and a flat slip stone, a little sandpaper, an abrasive pad, and some honing oil. Don’t expect a brand-new bit and chisel to be adequately sharp. Almost all I’ve seen needed extra attention out of the box.One common joinery method used in wood working is the mortise and tenon. A mortise is basically a hole in a piece of wood and the tenon is another piece of wood cut to tightly fit in that hole. The tenon is usually secured in place with either glue or a wooden pin or wedge. The biggest factor to consider when choosing a mortiser, is the size of the wood pieces you’re going to be using. Make sure to carefully note the maximum distance between the base of the unit and the bit, and make sure your pieces will fit between the two. Some have a fairly limited capacity, while others feature heads that can be reversed, so you’re no longer limited by their base at all. For exceptionally large pieces, like rough timber, go with an option specifically created for that, like the Makita, chainsaw-style option below. If you have a lot of mortises to cut for a wood workshop, getting a chain mortiser is the way to go. These machines are perfect for use in all types of conditions.

To use the attachment place the sharpened tynes onto the timber and engage full throttle - peak revs. Then simple plunge the guide bar slowly forward until the required depth is achieved. Return saw to idle and withdraw the bar from the timber. Reposition vertically or horizontally to achieve the desired mortice size and shape.

Although you can create mortises the old-fashioned way with a hammer and chisel, or with a drill press by making a series of round holes and then squaring them with a chisel, these dedicated mortisers are designed to give you square mortises with minimal chisel work needed.
