The first step in learning how to put a blade in a delta scroll saw is understanding the nature of scroll saw patterns. A scroll saw blade is a long metal tube, sometimes made of steel and other times brass, that contains a diamond grinding wheel. Each diamond plate has a preset teeth arrangement. Because each tooth is preset, the teeth on one plate can be moved by adjusting the setting on the grinding wheel.
This relationship between the teeth and the preset patterns is what makes the scroll saw such a versatile instrument. In addition, the distance between teeth also determines the pattern. If the spacing between teeth is too large, a perimeter will be cut instead of the interior of the pattern. If the spacing between teeth is too small, the interior of the pattern will be cut, but not the perimeter. The combination of these two factors dictate the types of cuts that can be made on a scroll saw.
Typically, woodturners use the interior of the pattern for making cuts. When a perimeter is not required, however, the delta scroll saw can still be used for this purpose. When a perimeter is required, the operator moves the scroll saw blade to the appropriate position to cut the material. In doing so, the operator now uses the same action as if she had used a standard woodturning machine.
How to put a blade in a delta scroll saw is achieved through two actions: disengaging the motor from the chain and blade and lifting the saw blade with a clamp. Once the blade is lifted, it must be placed into the saw’s notch. A locking mechanism keeps the blade in place and prevents it from being accidentally knocked out of the saw. It also prevents the motor from being damaged. Some scroll saw patterns have extra steps after the blade is in the notch; a locking mechanism that holds the blade in place prevents the motor from moving into these positions.
The other way to how to put a blade in a delta scroll saw is to use the blade with a standard wood turning machine. A woodturning machine is able to turn wood faster than a scroll saw. Because of this, it often has a longer teeth surface. The teeth of a scroll saw are usually closer together than those of a woodturning machine. This combination of close teeth and increased speed results in a shorter overall blade length.
Another option to how to put a blade in a delta scroll saw is to use the machine with a reciprocating saw blade. The two laws are similar, with one main difference: the scroll saw is powered by a counter-rotating blade while the reciprocating saw is powered by a fixed blade. Either saw can be used to cut materials with both sawing and ripping capabilities.
Some scroll saws are now equipped with programmable options. These feature an electronic scroll saw control unit that can be programmed for variable length cuts and other options. The most popular of these programs include AutoRack, which allows users to select certain sizes and lengths as well as program the depth of each cut. This feature is ideal for material handling that requires uniformity. In addition, AutoRack is compatible with most standard wood turning machines, but some scroll saws are designed to work only with the AutoRack system.
Finally, the most traditional method of how to put a blade in a delta scroll saw is by hand. For most scroll saws, this is still the best option because the scroll saw itself is generally quite durable. However, there is a downside to operating a scroll saw by hand. The operator must remove the material to begin the cut and then manually flip the blade so that the teeth come in contact with the material.
