How to sharpen table saw blades

A table saw can be one of the bulkiest and most expensive items on your woodworking machinery list, and when table saw blades break down , they can be expensive to replace. There may come a time when you need to replace your table saw blades, but you can get more out of them by sharpening them yourself. A dull table saw blade can not only ruin your work, it can also be dangerous as it can cut through wood and chip and fly towards you or others. This article will show you how you can easily and effectively sharpen your table saw blades.

Step 1 – Safety first

You never want to sharpen your table saw blades with them attached to the table saw. Choose a safe, flat surface where you can work and then remove the saw blade and bring it to this area. Just because table saw blades are not attached to the saw does not mean they are not potentially dangerous. They are still sharp, so be sure to wear work gloves when sharpening and handling the table saw blades. This can be messy work, so be sure to place a tarp on the floor where you will be working and to wear your goggles and face mask. When you start sharpening the table saw blades, you are limiting metal parts. These metal chips and metal dust can become very slippery on a concrete or wooden floor. They can also be dangerous to your health.

Step 2 – Sharpening the Table Saw Blades

This can be an arduous process that does not need to be rushed. Use your sharpening file and start sharpening a section of the saw. Use a strong blow back and forth across the section. Take several minutes for each section of the blade. Rotate the blade and continue sharpening until you are satisfied with the result.

Step 3 – Lubrication and fixing

To keep your saw blades sharp and rust-free, you need to lubricate them. Since the blade is freshly sharpened, it doesn’t need a lot of oil. Squeeze a small amount of lubricating oil over the entire blade, including the sharp edge. Take a wad of newspaper and rub the oil on the blade. Spread it out as much as you can and don’t worry if you remove some of the oil in the process. When done, replace the blade.

Step 4: test run

Get a piece of wood and cut it into several pieces with the saw to test the sharpness of the blade. You will know if the blade is sharp enough. If the blade is not as sharp as you would like, repeat the steps above.
