Makita 7104L/2 240V Chain Mortiser

Product Information

Mortisers come in several different types, but they all have the same purpose: to create holes in wood pieces for tenons to fit into. These “mortise and tenon” joints are popular because of the strength they provide to furniture pieces, and, thanks to mortisers like these, are relatively simple to create. As with all woodworking machines, the more rigid it is, the more repeatable accuracy you’ll have. It should also be more durable. 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. It’s possible to cut mortises by hand, and, in fact, doing so was once considered a test of a woodworking apprentice’s skill. If you’ve only got a few mortises to cut, then doing so with a chisel and mallet is far and away the cheapest way to do it, too! But if you cut mortises on a regular basis for furniture or construction, a good mortiser soon becomes invaluable.

What makes this device so handy is the long handle and smooth gear transmission that creates greater efficiency and speed when setting up and making the cuts you want. Add to this the movable table, which allows you to place the material with precision, and you can create accurate cuts time and time again. When buying a chain mortiser for woodworking, just remember that they come in two different types i.e. portable machines and stationary machines. Depending on your requirement and usage, you can choose the one that fits your needs. Add to this the cutter chain, a wrench for set up, a sharpener holder, and oil to keep it running smoothly, and you have one high-quality chain mortiser.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. Snedden's Mortice Safe Chainsaw attachment allows the operator to use the tip of the chainsaw to cut mortices into any timber - safer ,easier, more accurate cuts are achievable

Guides allow you to move the workpiece horizontally, so you can make further cuts to get a rectangular hole of whatever size you need. 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. A clear template and instructions are provided for easy fitting to your bar - just 2 holes drilled using a small drill press and 2 bolts. The bar strength is not effected. If yes, continue reading this article to find out about the best chainsaw mortiser currently popular on the market. You can also learn more information about chainsaw mortisers in case you are a beginner. This article will help break down all the features and specifications to look out for when buying a chainsaw mortiser. To reduce clogging, I spend time tuning up the bore. The smoother the bore, the easier it is for chips to slide up the auger bit. I use a chainsaw file to remove any in ternal burrs or machining grooves. A small, round, tapered slip stone works well for cleaning up the ejection slot.Tilt: Several high-end mortisers offer a tilting head, meaning you can cut angled or even compound mortises (ones that tilt through both X and Y axes). Clamping Horsepower: Motors are rated in either amps or horsepower. While direct comparisons aren’t very accurate unless you know the efficiency of the motor, we can assume that 5 amps (A) equals 1/2 horsepower (hp). It’s the most common size you’ll find on benchtop mortisers. They are 120-volt (V) single-phase mortisers, so you can run one from any standard household outlet. If, however, you have only a few small mortises to cut at home for a small project, a drill press equipped with a mortising bit will be a more suitable option and can work.

It’s also quite safe to use, thanks to the safety switch that protects the user. The weight of the machine is, however, a bit more than the Makita as it’s around 55 pounds.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 We’ll assume those who are shopping for chain and door mortisers already know what they’re looking for — both are very function-specific tools — so we’ll concentrate on the shop models, which are much more common and have much greater variety. The things you want to consider as you shop include power, construction, capacities, and clamping. Power Winner of the Land National Farm Inventor of the year 1996 and another 5 Australian awards. We manufacture the attachments ourselves in Australia from top quality materials. The tynes are made from Bisalloy and max wear and strength then the attachment is zinc coated. 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.

Health & Safety should be assessed on an individual basis. The advice given here should only be used as a guideline. It is the responsibility of the Employer and the Operators to ensure that they are competent and qualified to use the equipment and that they have taken the necessary safety precautions Floor-standing models invariably have a steel cabinet as the base, which gives proper support for a heavy machine and provides useful storage, too. These things can weigh several hundred pounds, so it’s a good idea to plan its position carefully, You won’t want to be moving it often! As the motor rotates the spindle, a handle plunges the chisel into the wood. The drill bit removes most of the waste, making a circular hole.What makes this tool so efficient is the chain that features sharp teeth to create clean, precise cuts at speeds up to 1000 feet per minute. The square sides of the chisel then remove the rest, so with one plunge motion you make a perfectly square hole. 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.
