What is a Rafter Hook for a circular saw? Until about ten years ago no one manufactured a one-size-fits-all hook to attach to any and all circular saws. However, with the advent of a few innovative companies, such as Spyderco, to name a few, it has become possible to install hooks that are universal to all types of saws. This is important because many individuals mistakenly believe that only their particular saw allows them to connect the hook.
Many people will attempt to install the circular saw’s bow arm using their own one-piece hook, which does not provide the security and stability necessary to hold the hook in place while the saw is in use. This could cause the arm to lock up, causing the motor to cease functioning and potentially damaging the saw. Even worse, an improperly attached rafter hook can become a safety hazard. The manufacturer’s product manual may specify a distance between the hook and the bow of the saw, but very few manufacturers take into account the possibility of the hook running afoul of the pulley or the chain drive when it is not securely fastened to the saw.
A variety of different types of hook are available for use with saws, including a ratchet/parabolic type, a double-ended worm drive circular saw, and even a cable tie. In addition, there are several different ways to secure the hook on the saw. Most notably, it can be secured by fastening it through the top of the arbor on the back side of the saw. This provides excellent security, as the hook is completely out of the way. It is also possible to fasten the cable tie directly to the bow arm, securing the hook even more firmly.
Securing a worn drive circular saw with a rafter hook is usually simple and straightforward.
The primary reason for this is that it eliminates one of the more potentially dangerous aspects of using this type of saw – the sudden shock and vibration that occur when the saw is turned on. Because this is the case, most manufacturers advise against changing a previously used worm drive with a new circular saw. As a result, it is usually best to select a new worm drive from a reputable supplier.
For those homeowners that decide to go ahead and change their circular saws, the basic idea behind the ratchet/rafter hook is relatively easy to understand. Essentially, the ratchet provides a secure base for a cable to be run through. On the other end of this cable, a set of teeth on the Rafter, or face of the saw allows the user to turn the device in a counterclockwise direction to lock the teeth, effectively cutting the cable loose. One of the more popular ways to use a ratchet in conjunction with a new circular saw is to use it as a sliding knife to cut away the excess material as necessary. While this method is often considered ineffective and inconvenient, it can be useful in eliminating areas of excessive wood and plastic.
In addition to providing a base for a cable to be run through, the design of the ratchet/rafter hook also includes a flexible piece on one end that fits snugly into the grooves cut into a circular saw’s face. This flexible piece is designed to allow the user to simply grab the end of the cable and, in one swift motion, pull the flexible rubber band back out of the grooves on the face of the saw. After which, the device will spin freely in place, effectively removing any excess plastic or wood from the interior of the saw. At the same time, this action also disengages the teeth on the circular saw’s blade and protects the steel blades from any potential damage.
The ratchet and rafter hook serves a very important practical purpose
they make it easier to remove material from a circular saw. While this can obviously be beneficial, there are also times when such a feature may pose a real danger to the user. This is particularly true whenever the user has not installed the appropriate screw on their saw’s motor housing to prevent the device from being driven at high speeds while at rest.
Despite these potential hazards, the ratchet/rafter hook is still a valuable part of many circular saws. The majority of units sold today come with both a standard and a worm drive circular saw driver, meaning that the user can select the appropriate one for their needs. On some models, users may also have the option of purchasing a helical saw attachment. All in all, there are many positive aspects to the use of the ratchet/rafter hook on circular saws – they allow for the safe and convenient storage of bulky or potentially dangerous parts, they protect the user from possible damage to the blades, and they make it much easier to remove material without damaging the blades themselves. There are only a few drawbacks to the use of a ratchet/rafter hook, making them a worthwhile inclusion in many quality circular saws.
How to Install a Rafter Hook on a Circular Saw
It is relatively easy. Some of the steps are shown here for you to follow when learning how to install this important tool for your circular saw. If you know someone who also uses a circular saw then let them know how to do it so that they can also gain some valuable information from them as well.
The first thing that you will need to do when learning how to install a rafter hook on circular saw is to attach the saw’s arbor to the bow of the saw. You will need to measure from the fender to the edge of the saw’s arbor. Mark this location. If you are not sure how to use this tool then get a friend or family member to help. This is an important step, especially if you have a newer or heavy-duty saw.
Once you have marked the spot where the hook will be mounted, you will want to tilt the saw’s arbor upward until it rests comfortably on the edge of the arbor. You can do this by hand or on an arbor grip. This should prevent the saw from getting hung up on the edge of the arbor while it is in use.
You will then screw the hook end of the bolt into the fender. You will want to do this about halfway into the cut. Once the screw is fully secured, you can then secure the saw’s other side of the hook by installing some screws on the fender. You will want to make sure that the screws are drilled through the fender and the edges of the arbor before tightening.
To continue with how to install a rafter hook on circular saw instructions, you will then need to turn the saw on its side or back. This will allow you to slip the hook end of the bolt through the slot in the rafter. It may be necessary to also drill some more holes into the rafter before tightening the screws. Make sure that your saw’s teeth are lined up with the holes in the rafter.
Installing Rafter Hooks on circular saws is not as difficult as it seems.
The key is making sure that you have prepared the area completely for the installation. The best way to do this is by lining up the cut edge of the saw’s arbor with the mark where you will drill the screws. You will then proceed to install the hooks by tightening the screws. It is important to note that you should not attach the ends of the rafters using the screws – this will make them untidy and harder to clean later on.
In order to ensure that you get the best results when learning how to install a rafter hook on circular saws, practice the process on a piece of wood that can act as a template. Hold the saw at an angle in order to make the cut as straight as possible. Do this by tracing a line from the middle of one of the circular blades to the opposite end. This line should be parallel to the surface on which you will be cutting. Once you are comfortable with this process, attach a piece of wood to the saw and let it slide along the traced line while you manually adjust the saw’s arbor.
Finally, you will want to make sure that your saw is turned on its side or back already. This will prevent the material from coming out of the sides of the saw and cause you to over-tighten the screws. You will learn how to install a rafter hook on circular saws fairly easily if you follow these steps diligently. With a little practice, you should soon be making similar cuts to those you see professional woodworkers use on their crafts.
