The portable sawmill business can be very lucrative. However, replacing your portable sawmill blades all the time can lead to a lot of unnecessary costs. That's why there are certain things that every sawyer should know about sharpening their blades.
Terminology:
First, you should know some basic terminology. For example, you need to understand things like tooth spacing, gullets, hook angle and tooth face. You also need to have some understanding of the construction of the blade body itself.
For example, some blades are built to be more flexible than others. Flexible blades last longer, but may not be capable of cutting through certain types of lumber well. Rigid blades might be stronger, but won't last as long.
As for the tooth terminology, tooth spacing, gullet and tooth face, those are not as complicated as they sound. The tooth spacing just refers to the number of teeth on a given blade and the distance between one tooth and the next. The gullet refers to the “negative space” between each tooth on the blade. As for the tooth face, it's the sharp, or at least hopefully sharp, front edge of each tooth that is responsible for cutting into the lumber.
You could just replace blades when they wear out, but it makes more sense and saves more money to sharpen, set and flatten the blades periodically. Luckily, there are plenty of simple tools that you can buy to accomplish those tasks. So, do you want to get started?
