For the uninitiated, learning how to change the blade in a ryobi scroll saw is a vital skill. The blade is the most expensive piece of equipment found in a woodworking shop, and its condition and performance can often determine the success of a woodworker. This basic step-by-steps guide should provide any woodworking person with an average understanding of how to change the blade in a ryobi scroll saw. Following the guide is usually simple and easy for even beginners to accomplish.
The scroll saws blades come in two different sizes: small and large. The saws with small blades are called small scrollers and the larger ones are sometimes called big rollers. Most woodworkers use the term ‘large scrollers’ when they refer to saws with blades as long as 45 inches, which is about three to four inches longer than the small ones.
To change the blade in a ryobi scroll saw, you need to remove the blade and set it aside. There are generally four screws that hold the scroll saw together, namely the cam lever, the bed assembly, the sprocket, and the vane bed. First remove the cam lever by loosening the bolt that attaches it to the cam groove on the rear of the machine. After loosening this screw, detach the cam groove by pulling the rear side of it toward you. Set the new cam lever into the corresponding grooves on the other side of the machine, making sure that both loops are visible. Use your hands to guide the new lever as it fits, making certain that the tooth faces the right direction.
Next, you will have to remove the spring that holds the blade properly in tension. This can be accomplished with one of two methods: tensioning the spring in a drill press, or mentioning it manually by hand. The first method is easier and can be done by yourself if you have the appropriate tools. On the other hand, if you don’t have these tools, you can leave it to the experts and follow the instructions in the manual.
Next, the wood shim that is located between the bed and the fence must be adjusted properly. By tightening the shim in the correct location, you will be able to prevent vibration from happening to the work surface as well as to the blade, which results in less wear and tear. If you are using a saw with a two-inch cutting capacity, then you need to adjust it according to the following illustration. If the shim is positioned at an angle of thirty degrees to the line of sight, then you will need to increase the height of the fence by three inches. If you use a saw that has a three-inch cutting capacity, then you only need to raise the fence by one-third of an inch.
If you have a vertical scroll saw, then you can also adjust the height of the parallel arm by loosening the screws that control the variable speed motor. On the other hand, if you have a horizontal scroll saw, then you need to tighten the screws so that the blade doesn’t slip while cutting. Adjusting the saw’s depth depends on the amount of wood that you are cutting and the distance between the fence and the work surface. The depth of cut is defined according to the diameter of the wood.
The pulley system that controls the motor also has to be adjusted properly. This is normally done by unscrewing the wing nut and removing the blade from the shaft. Then you need to look for the screw that attaches to the pin-end of the pulley. Remove the screw and set the blade aside. The new blade should be installed into the same manner as the old blade was.
How to change the blade in a Ryobi scroll saw blades requires a little bit of practice. This is because it takes a couple of seconds to zero in the blade before you can actually start cutting. Make sure to practice on paper or some kind of hard material with a smooth, flat surface.
