Among the machines that one can use for drilling holes in timber workpieces are mortising machines. They are designed to offer the user, be it a professional or a DIYer, the freedom to drill holes of their desired shapes on any workpiece.
Even though they exist in different models, their goal is the same and that is helping you get a hole on your timber workpiece to fix any accessory you want.
Different types of benchtop mortisers
The main types of wood mortising machines are:
Square Chisel Mortiser
The first type is the square chisel mortiser. Also called a hollow chisel mortiser, this type is similar to a drill press for drilling holes in wood in most aspects. The main similarity is that it combines the action of a drill bit and the cutting power of a four-sided chisel in the center.
A square chisel’s drills are versatile and can be fixed to a normal drill presser using mortising attachments.
The horizontal mortiser, also called a slot mortiser, is a more recent innovation in the family of mortisers. It is designed to incorporate a router that is mounted statically on the side with the workpiece which is clamped to a multi-axis sliding surface like a table.
This mortiser produces mortise and tenon pairs as well as floating or loose tenons. The floating tenon involves pieces of wood joined together and have aligned mortises. The aligned mortises are cut and separate pieces of wood are milled into fitted tenons.
A chain mortiser is designed for cutting larger mortisers. The examples of such mortisers are the ones used for timber farm construction purposes.
A chain fitted with cutters like a chainsaw rotates within a frame that is clamped to the workpiece. The chain is then successively plunged into the workpiece and the required volume is mortised.
Getting the most out of your benchtop mortising machine
The tips below will help you get the most out of your benchtop mortiser and ensure you operate it safely.
Include A Hold-in Device
For a firmer working relationship with your mortiser, you should at least try and add a hold-in device that will secure the workpiece into place. Such devices can be included with premium machines but even with a budget option, you can use makeshift ones.
You can use accessories that have the ability to hold the workpiece and limit movements as you work. The accessories should be fixed to the cast-iron base of the mortiser and space will be created to fit the piece you are drilling holes into.
Cut the Mortises Slightly Deeper
This is a little but handy tip to help you save the time. When you cut your mortises, it is advisable to set the depth stop in a way that it will bore into the wood slightly deeper than the tenon’s length. Having a deeper boring will help you avoid cleaning up the bottom of the mortise for the tenon to fully fit into place.
Install the Bit and Chisel Correctly
The square hollow on your mortising machine is designed to work in tandem with the drill bit that’s located inside. This is a simple principle and the bit is used for removing the waste elements when the chisel pares away the corners and edges. What is more important is to ensure you have the right spacing between the bit and chisel tips.
How to choose the best mortise machine
Every power tool or any other machine in your workshop should be one that promises return on investment. The same is true for a mortising machine and as such, it is paramount that you observe some key considerations as expounded below:
The Table Size
The overall workspace while using a mortising machine is an important consideration since it determines whether the workpieces will fit on it. When you’re looking for the best mortising machine to buy, therefore, you should consider one that allows for or has a large work surface to support your work without needing alternative rigging.
The Motor Size
The motor size is measured by the amperage and rotations per minute. A good mortising machine is one that combines both to offer seamless operation and give the desired results. When you are shopping for one, therefore, you should ensure to get one whose amperage and RPMs allow for enough power under the hood.
The Chisel Capacity and Bit Changes
Among the most crucial factors determining the operations of a mortising machine are the accessories. Such accessories include the bit changes and chisel capacity. They also determine how the results will be which calls for due diligence and a careful consideration of the same while selecting a machine of choice.
Length of the Feed Lever
How long is the feed lever of the machine that you are looking at? This is a question you should ask too before settling on a specific machine. A good feed lever should be long enough to ensure the user gets as much leverage as possible when they lower the larger diameter bits into a workpiece.
The Depth Stop
The depth of the machine you’re buying should be easy to adjust. It should also not flex under pressure and should also be accurate. If you’re looking for efficiency then, you know what to look for in a mortising machine.
How Far the Head Travels
The other consideration is how far the mortising machine’s head travels. This is also called the stroke of the machine and means how far the bit travels along a vertical axis when the lever is pulled. If time and efficient are your ultimate considerations, you should not compromise or fiddle with the extent of the stroke.
The Fence System
When you’re looking for a mortising machine, the fence system should also guide you into making the right decision. The larger the system the better. You should also consider a fence system that is at least flat across the face or at least 90 degrees to the table.
