Check Your Tension?

One way to speedup clipper blade sharpening is to set the tension of the blade with the Nebraska Blades’ Clipper Blade Scale before you sharpen. To do this, slide the top cutter out about half way. Look at the ware pattern; it should be clear, very shiny and on every tooth. If so, this blade was cutting well; it’s just dull. You more than likely will not have to do anything with the tension, even if it feels too light.

If the blade does not have a good pattern, maybe the blade was given to you by mistake; make a test cut to see. If it does not cut, check the tension, it should be about 2.5-3.5 pounds. Are the screws loose? Is the glide shot? If not, now is the time to add tension to the spring. I have used different tools to do this, but Nebraska Blades’ Tension Set Pliers have a special grind with red markings that align with the spring (Figure 2). Also, do not forget to set the sockets at this time. The Tension Set Pliers are also useful for setting the Deluxe Socket Setter, as seen in Figure 3.

Now do all of your sharpening, demagnetizing, cleaning and reassembling of your blades; 97 percent to 99 percent should cut well. Take care of the few that do not by adjusting the tension or re-sharpen if need be, but re-sharpening should be very few.

Remember, the range is 2.5-3.5 pounds of tension. This is just a rule of thumb though, I have had blades at three pounds that were iffy, but cut great at 3.5 pounds. Also, some blades were at two pounds or less, but cut very well. Use as little tension as possible, as long as the blade still cuts well. Too much tension will dull the blade, and it may heat up too much (it is also bad for the clipper). If you need to take tension off, you can do this with a screwdriver at the end of the process.
