Scroll Saws – How to Select the Correct Blade?
Scroll saws are never complete without having the correct blade since it can have a great effect on several things. These comprise the smoothness of the cut and the safety of the person who runs the tool. Here are some of the things that you should look out for when choosing the blade.
The first thing you keep in mind is the kind of material you need to cut. Standard blades can cut nearly all woods but you need specialty blades for some materials, including Plexiglass. You can look at the charts that most manufacturers provide to find out the appropriate blades recommended for the speed and thickness of materials.
The blade quality will impact the cut of the materials so you ought to consider that all blades are stamped from steel blanks. However, most blades for scroll saws are hardened and tempered so the quality is significantly influenced by the steel quality used and the tempering process. Consider also the quality of blade that has a higher number, especially when cutting hardwood and oily woods because the blade kerf of the cut width is larger that allows easier dust clear out. A skip tooth blade, which has more space between the teeth, ought be used while cutting gummy white pine. It really requires a lot of trial and error when it comes to choosing the right quality of blade for scroll saws.
One more factor to think about when selecting the type of blade is the thickness of the wood. Thick wood needs a blade that has less teeth per inch, but this is opposite when talking about thinner wood. It is recommended that you use a blade that has at least 4 teeth in the wood at any given moment, but 3 teeth will be okay already for very thin wood. The reason is that there is no way for the sawdust to clear out when the blade has excessive teeth as it will just heat up and will burn the wood. Also, too many teeth will cause them to catch onto the wood and the blade will go out of control on the table. If you want complex patterns, a finer blade can offer more control. Long curves on the outside of the wood involve greater cutting speed so you must have a blade with fewer teeth. Though the cut will be rougher, it will be far quicker to cut the wood.
On Equipment: My Rationale Explained
If it is your first time to use a scroll saw, choose a blade with more teeth and heavier gauge for a much easier control. Keep in mind that a blade with lower Teeth per Inch (TPI) will be quicker than the one with a higher TPI. When picking blades for scroll saws, find a middle ground in view of the cutting speed, finished edge quality, the path of the blade, and its life.The Beginner’s Guide to Equipment
