Sharpening Table Saw Blades By Hand

If you want to sharpen your saw blades by hand, you only need a few simple tools and no experience. The best thing is that you won’t have to take the table saw blade off to complete the task!

First cut a piece of wood that is 12 inches long into a 20-degree wedge. Attach an inexpensive diamond sharpening stick to the wood using double-sided adhesive.

In order for the diamond stick to come into contact with the saw blade’s teeth, insert the stick into each gullet. For saw blade sharpening, move the diamond surface back and forth while maintaining a perpendicular angle with the teeth.

The advantage of this system is that the table saw is used to drive the grinding wheel. You don’t have to spend a lot of money on hand tools or expensive blade sharpening equipment. 

The jig comes with instructions. To maintain alignment, it makes use of runners that rest in the miter gauge grooves. You can work with a variety of blade sizes thanks to the interchangeable center strips, and an adjustable block enables you line up the teeth for grinding.

To sharpen the blade, you use the jig to move it back and forth across the grinding wheel’s tooth edge.
