What Is A Jointer?

A jointer, better known as a surface planer, planer, flat top or buzzer is part of a woodworker’s essential equipment that he uses to make a flat surface along the length of a board. It derives its name from its basic function of creating flat edges on boards before joining them at the edges to make wider boards. Difference between jointer and planar Novice woodworkers always ask, “What is a jointer?” as much as they want to know the difference between jointer and planar. Basically, each machine is meant for a unique surfacing need. Though both woodworking tools are required by professionals to get the maximum out of rough lumber, yet the basic function of a jointer is to flatten a surface or straightens an edge. A planer is used to flatten the second surface and make it parallel to the one made by the jointer. Thickness Planers: A thickness planer takes rough sawn boards and converts them into boards of consistent thickness along their length. They are smooth and flat on upper and lower surfaces. This is done by getting one surface to a reasonable smoothness and flatness. This board is then turned over and the opposite side is also smoothened and flattened similarly. Since the timber is put through a series of rollers, the end result is a consistent thickness. Typically, a planer comprises: An adjustable table proportionate to the real cutting head that determines the overall thickness of the board An in-feed and an out-feed roller that send the board through the planer A cutting head with rotating blades that cover the timber Wood Jointers: The primary function of a wood jointer is to create one flat edge on a board which can then be joined at the edges to make a far wider board. This device comes with two tables parallel to each other and known as an in-feed and an out-feed table. They are placed above the cutter head so that the jointer creates a completely straight and a square edge. When two boards are placed together, they fit perfectly and the strong joint that ensues is nearly invisible. Advantages of jointers and planers These two devices are both similar in many ways though they perform different functions. Yet, each has its own advantages, such as: Woodworkers use both these machines to smoothen wooden boards, yet a jointer smoothens the edges of the stock allows the edges of both boards to be joined. A jointer can also joint or smoothen the surface of a board. A jointer is also used to flatten a twisted, warped or bowed board. On the other hand, a planer...

What Is A Hammer Drill?

An overview of what is a hammer drill, types of hammer drills and its applications.  Although a hammer drill has got little to do with woodworking, (it is mostly used for masonry work), we thought we must mention what is a hammer drill anyway. However, if you are using the hammer drill for woodworking purposes make sure that the speed can be varied right down. So a hammer drill is known by several names, such as a rotary drill, rotary hammer, hammering drill or roto-drill. Basically, it is a rotary or turning drill which works with a hammering action. The hammering action gives a short and quick push to crush brittle material and enable drilling with less effort and quickly. A hammer drill is electrically connected and also runs on batteries. Types of hammer drills There are primarily two types of hammer drills, the cam action type and the electro-pneumatic type. Cam-Action (Percussion) hammer drills: Drills with lower power units are known as hammer drills and have a percussion hammering method or cam-action. Here, two sets of gears with teeth interact with each other mechanically to hammer while turning the drill bit. In these drills, the chuck works by moving forwards and backwards on the rotary axis and the motion is secured with the chuck’s rotation. It’s common to see this kind of drill used either with the hammer action or without. However, using just the hammer action is not possible as the hammer motion is caused due to the rotation on the cams. Such units are smaller and run on modern-day cordless technology. These are used more for drilling masonry or concrete occasionally. Electro-Pneumatic: Rotary hammers are the more modern power units. They are larger and have a much larger impact force because they harness a technology known as “electro-pneumatic” (EP) hammering mechanism,” since it runs on electricity rather than a separate air compressor. It comprises two pistons—a flying piston and a drive piston. Modern rotary hammers and those jackhammers that run on electricity use this technology. In modern units, the rotation and hammer functions can either be used together or singly. These drills are largely used for masonry work. Dedicated hammer drill: Also called a rotary hammer, this tool is used by masons for drilling concrete. Corded drill with hammer option: This kind of drill comes with a hammer setting. It runs on electricity, so you needn’t worry about charging batteries. Cordless drill with hammer option: These drills are best used in the absence of electricity at the work site. Uses of hammer drills: Hammer drills are used in those situations where workers need to get the maximum out...

3 Must-Have Electronic Gadgets For Woodworking

If you’re looking for a gift for a woodworker friend that he’d appreciate, why not gift him digital measuring tools? These electronic gadgets are perfect for woodworking projects and they are so reasonably priced that they won’t pinch your pocket. Why buy electronic gadgets for woodworking? Well, to begin with, they bring a lot of accuracy to your work, are incredibly convenient and as gadgets, they are very appealing. For all their pluses, they are highly affordable and easy to wrap. For woodworkers, it’s a big boon. Here are some that you might like to consider for their individual strengths: Digital Fractional Calipers Using these calipers, you can measure extremely accurately and ensure it’s right. You needn’t work with a measuring tape and hope to God that your measurement is right. These calipers can be successfully used to measure material thickness, hole depth and diameter of a drill bit. When you go shopping for calipers, be sure to buy the fractional type like this one over here. With this gadget, you can measure in fractional inches and in decimal and in millimeters. If you buy digital calipers that aren’t fractional, they will read in thousandths of an inch and you will be left converting it into fractions, thereby increasing your work and leaving you confused and wondering if you’re right. All woodworkers will find the digital caliper extremely useful. If you too need to do a lot of calculations, consider buying a a Fractional Digital Caliper if you work in fractional notations. Fractional readings are available right down to 1/128ths of an inch, which is as accurate as you can get. By pressing a button you can get the readout in decimal form for the maximum accuracy. Digital Planer Read Out This add-on gadget can be installed on several different portable planers. This gadget is easy to use and it’s extremely accurate. All you need to do is to measure the thickness of the wood and set the planer to just a little below that and there you go. If you want to hit a particular thickness, using this tool would be more than sufficient because the readout here will give you the exact material thickness that leaves your planer. So, if you don’t have digital calipers, you can use this readout too to measure board thickness. Fractional Calculator This is a reliable tool which works as an excellent calculator. So, you don’t have to do any mental maths to get the right measurements. Now, using this calculator, you can enter any fractions and carry out all the required math functions. It helps you calculate in yards, meters, feet...

How to Choose the Best Hearing Protection

Do you want to know how to choose the best hearing protection for your wood shop or while working on a wood project – Read on… Though there’s a huge range of hearing protection available today, yet it pays to choose hearing protection designed especially for the noise you are trying to counter. Wearing the wrong kind of hearing protection may give you the wrong impression that you’re adequately covered (pun not intended), when actually the sounds at high frequencies like those made by a router can wreck your hearing forever. Benefits of hearing protection for woodworkers So, when we speak of hearing protection for woodworkers, what exactly are these professionals looking for? Comfort: First things first, they expect comfort. After all, woodworkers are going to be wearing them for indefinitely long periods. Compatibility with other safety gear: Since wood is the material woodworkers use, it is mandatory for them to protect their eyes in case bits of wood, chemicals and airborne dust fly up in the air when machine-cut. Lung protection is also imperative, since it is highly likely that they may inhale the talc or sawdust thrown up in the air from wood when cut by machine. High frequency protection: This is necessary for woodworkers who cut wood using a circular saw or router. Medium range volume protection: When woodworkers use a circular saw, it can screech very loud at close range, causing hearing loss to the woodworker. Woodworking, though innovative, can be dangerous. But if you follow a few rules, you can lower the risk of being severely injured. By getting into the habit of wearing the safety equipment outlined below, you will always want to work with it and be safe. Here they are for you: Kinds of hearing protection for woodworkers Ear muffs: Anyone wearing ear muffs will look like he’s wearing headphones. These ear pieces are one of the best ear protection as cover the ears completely and keep the sound out completely. They work to reduce the noise more than ear plugs do, despite their bulky size. This makes woodworkers treat this protection equipment with much skepticism. Ear muffs are available these days in their electronic avatar which serve to reduce noise levels much more. Ear plugs: Ear plugs aren’t as cumbersome as ear muffs, nor do they provide an equal level of protection. They are made from memory foam that the woodworker compresses and puts into the outer ear canal. The foam then expands to fit the ear completely and tightly. Woodworkers usually find these more comfortable to wear for protracted periods rather than ear muffs, particularly in warm weather. Other...

How to Choose the Correct Band Saw Blade Width

How to Choose the Correct Band Saw Blade Width

Band saw blades are available in a wide variety of materials, widths, tooth design and configurations. How band saw blade width is determined Band saw blade width is measured the tips of the blade teeth to the edge of the blade at the rear. When selecting blade width of a band saw, the relevant instructions for the machine in question should be followed. How to choose the correct band saw blade width The word ‘width’ in this context refers to: the maximum capacity of a particular band saw; and the minimum radius a woodworker would want to cut. For example, if you’re resawing or doing cut-off sawing or cant, the maximum blade width of your machine should be used. This will ensure you get really nice, straight and neat cuts and you’ll also get a good feed rate without any blades breaking. At the other end of the spectrum, if you’re into contour sawing, use a blade that’s narrow enough to cut the required radius. These blades can cut a much smaller radius than their wide counterparts when they are cutting a curve. For instance, if you use a 3/4-inch- wide blade, it can cut a 5-1/2-inch radius (as shown in the table below), just as a 1/8-inch blade can cut a 3/16-inch radius. Here’s a chart that will show you the correlation between blade width of a band saw blade and the minimum radius it can cut: Blade Width Minimum Radius 1/8″3/16″ 3/16″5/16" 1/4″5/8" 3/8"1-1/2" 1/2"2-1/2" 5/8"4" 3/4"5-1/2" 1"7" Source: Choosing And Using Bandsaw Blades, https://www.kmstools.com/blog/choosing-bandsaw-blades Band saw blade width can also be chosen according to the number of teeth per inch (TPI). Through this, the desired finish and the correct feed rate can be obtained. A coarse tooth blade of about 2 or 3 TPI can be used to re-saw wood and cut thicker stock to a maximum of eight inches. For cutting thinner metals and plastics below a quarter inch in thickness, one can use a fine-toothed blade, ranging from 18 to 32 TPI. If you cut wood of about 3/4″ thickness, use a 4TPI blade for a fast cut and 14 TPI for a slow cut but an infinitely smoother finish. While choosing a blade for your band saw, remember that the wider blades are stiffer and work well for cutting metal. They also track better on band wheels than on narrow blades. If thicker material must be cut, a wider blade is less able to deviate because when the back end is in the cut, it steers the front part of the blade. When you re-saw a piece of wood, the narrower your blade,...

What is a wood Router? What is it Used For in Woodworking?

Is wood crafting your hobby or you are a professional woodworker? If yes, you probably know that you need a large variety of tools to get the best, one of them being a wood router. This amazing tool is equipped to help you in completing all the woodcraft projects you undertake to express yourself in wood. To know more about the applications of wood routers and their place in the world of woodcraft, read on. What is a wood router? A wood router refers to a tool that helps woodworkers cut, shape or trim all kinds of materials in wood. However, it’s important to note that there are several types of routers available apart from a wood router, for instance power routers. Besides, there are those routers that are meant to cut, trim and shape plastic, metal and other materials. With woodcraft as your hobby, you will choose to use a wood router to give a piece of wood a particular shape so that it can be joined to another piece of wood which can be added on to another, pretty much like a jigsaw puzzle. By this means, you do away with using brackets or adhesives in joining two pieces of wood. So, to make a chest of drawers, you can use a tongue and groove joint. What does a wood router comprise? A wood router comprises a router unit, a cutting tool (bit) and a guide template. Uses of wood routers: Wood routers are used to make tables, chairs, shelves and staircases and for making any other kinds of wooden fixtures. Types of wood routers: Wood routers are of two kinds, and are widely used in the construction and carpentry industries: A large wood router placed on a table: Here, a large wooden hand plane and a slim blade peep out of the plane. It is helpful in making all kinds of patterns and wooden cuts for creating fixtures and furniture. A hand-held router or router plane: This device is smaller than its table-set counterpart and more versatile. It can be used to cut large slabs of wood to make furniture and fixtures, and trim the edges of finished furniture so that you can add an elegant trim design to lift your wooden creation. You can also use this device much like the table-mounted routers in joining two pieces of wood without the use of nails, brackets or adhesive. Spindle router: This type of router has a vertically set electric motor and a collet or holding device on its shaft. The user uses this device by holding tight to its handles. The spindle has two sub-types: Plunge-base...
