When using a scroll saw, there may be problem with the saw such as the blade wandering on a piece of wood or the blade leaving burn mark on the piece of wood. These problem can be caused by using a scroll saw blade that isnt appropriately for the task that the user is performing with the saw. The width of the scroll saw blade can impact the way that the blade perform when its being used.
Blades that is wide can provide more stability to the blade, but can be less agilely. Because of the wide blade, it is more appropriate to use such a blade when cutting through thick piece of wood. However, if the blade is too wide for the work that must be performed, the blade may get stuck and snap.
How to Choose the Right Scroll Saw Blade
Thin blades provides more agility to the saw and are therefore used when cutting intricate piece or objects with small curves. The number that is assigned to the scroll saw blade relate to the number of teeth on the saw blade. Blades with a high tooth count will cut smooth piece of wood.
However, if the user use such a blade on thick hardwood, the saw blade will quickly become filled with sawdust in the grooves of the blade, preventing it from properly cut the wood and causing the wood to burn on the blade. Skip tooth saw blades has large gaps between the saw teeth. The gap allow for the saw blade to remove sawdust created when cutting the wood.
Skip tooth saw blades are used when cutting plastics or wood containing resin because they prevent the plastics or woods from melting on the saw blade. Reverse tooth saw blades prevents the cut of the wood from splintering on the bottom of the workpiece. These are used when cutting veneered plywood, as the saw blade will not cause the plywood to splinter on the bottom of the plywood workpiece.
Scroll saw blades come with different end shapes. Plain end saw blades come in a variety of sizes. Plain end saw blades are used for cutting thin pieces of wood.
Pin end saw blades is also available, but are limited to large sizes due to the saw blade pin taking up some of the physical space of the blade. Pin end saw blades are installed at a faster rate then plain end saw blades. The speed at which the scroll saw blade is run can impact the saw performance.
Scroll saw should not be set to the maximum speed for all type of materials. When the operator run scroll saw blades at high speeds on plastic materials, for instance, the plastic may melt and adhere to the blade. Therefore, the saw must slowly adjust to cut the plastics rather than rub against the plastics.
Finally, the tension of the blade must be adjusted appropriate. If the tension is too low, the blade may wander on the piece of wood. However, if the tension is too high, the blade may snap on the wood when it come across a knot.
The tension should of been adjusted so that the blade feels firm and stable in the wood during the sawing process.
