On a blade, the cutting edge is the sharp side.
On a blade, the cutting edge is the sharp side.
The sharp side is opposite where you would normally expect it, while the normal cutting side, is the wide unsharpened portion of the blade.
A drop point blade has a convex curve of the back, the opposite side of the cutting edge, towards the point.
Remove the blade. With a med file, slide the file on the blade side from the center to outside until it is smooth. Then sharpen other side from center out. Place the blade on a balancing cone, file the heavy side until it balances on the cone.
Hold the blade stationary and turn the bolt counter clockwise until it comes out, put the blade on with the flat side down, cutting angle up and make sure the blade is flat or level on the spindle and tighten while holding it in position.
A hair clipper is nothing more than an electric motor with a cutting blade attached to it. The motor shaft is usually connected to the blade in a fashion that moves it side to side. One way to do that is by connecting the motor shaft to a wheel, cam, or rod that changes the rotational motion of the shaft to the desired motion of the blade: side to side, up and down, etc. The method commonly used is an eccentric ( a cam lobe ) connected to the motor shaft. The eccentric is then placed into or onto the cutting blade which moves in a guide. If you look close while a hair clipper is running, you can see that the motion of the blade. It moves slightly up and down as well as the desired side to side motion. That is a result of the offset of the eccentric from dead center of the motor shaft as it makes a revolution.
It is called "set" in the teeth. It takes a the sawdust out of the cutting surface so the saw will not bind as much.
The orientation of a lawnmower blade depends on the specific design of the mower and the blade itself. In general, lawnmower blades are installed with the sharpened edge facing down toward the ground. The cutting edge should face the grass to ensure an effective and clean cut. Here are some key points to consider: Sharpened Edge Faces Down: In most cases, the sharpened edge of the lawnmower blade should face down. This means that the cutting edge is oriented toward the ground, allowing it to make contact with the grass and provide a precise and efficient cut. Check Manufacturer's Instructions: Always refer to the manufacturer's instructions or owner's manual for your specific lawnmower model. The manufacturer's recommendations may vary based on the mower design and blade type. Blade Replacement: If you're replacing the lawnmower blade, make sure to install the new blade in the same orientation as the old one. This helps maintain the proper cutting performance of the mower. Balancing: Some lawnmower blades are designed with a specific top and bottom. If your blade has a designated top side, make sure it is installed correctly for proper balance. Inspect the Cutting Edge: Before installation, inspect the cutting edge of the blade. The side that has the sharper, beveled edge is the side that should face down. Safety Precautions: When removing or installing a lawnmower blade, be sure to take appropriate safety precautions. Disconnect the spark plug or power source to prevent accidental starts, and use gloves to protect your hands. Always refer to the guidelines provided by the mower manufacturer to ensure that you install the lawnmower blade correctly. If you're uncertain or have specific questions about your lawnmower, consult the owner's manual or contact the manufacturer for clarification.
You will need a 21" blade for the driver side and a 19" blade for the passenger side.
The larger wiper blade goes on the drivers side
I have a 2008 Honda Pilot myself. The driver's side is a 24" in. blade, and the passenger side a 21 in. blade.
