How To Choose The Right Bench Grinder For Your Workshop
At first thought, a bench grinder might be considered a very simple tool that is less important than others found in the workshop. But by keeping tools clean and sharp it can improve the efficiency of the work that's being done and it can reduce injuries. This makes choosing the right bench grinder for your workshop of great importance.
The bench grinders that are needed for an average workshop are not very expensive and they are not very big so they don't take up a lot of room. The only thing that you'll need to do to secure the grinder is to mount it on a workbench. A quality grinder is easily able to repair punches and drivers, it can help smooth out welded joints, restore drill bits, knives, and scissors.
For the majority of workshops that are at home, it will not be necessary to get a super high-powered commercial grade grinder. A grinder with a quarter or a half horsepower motor is more than adequate for most users. The wheels should be half an inch to an inch wide and five or six inches in diameter.
For home use, there are larger grinders that are available and these are usually more powerful. The wheels are as much as eight inches or more in diameter and they will rotate up to 3600 revolutions per minute. This type of bench grinder will have 2 grinding wheels with each one on opposite sides of the motor. These wheels will have a guard that leaves about 90 degrees of the wheel exposed to access it for grinding purposes.

Prerequisites For Using Your Bench Grinder
1. Do a complete safety check before turning on the grinder. Best Practices include checking the grinder to make sure it is firmly secured to the workbench. You will need to check the tool rest which is where the metal item you're working on will sit, and make sure that it is also secure. Make sure that there is no debris or objects that are around the grinder and there needs to be enough room to move the metal piece you're working on back and forth.
When you're working on metal with the grinder it can sometimes get too hot. To cool the metal down you will need to place a container of water near the grinder. Simply place the metal in the water anytime it gets too hot.
2. Safety wear should always be worn when using a bench grinder. Make sure you have a set of safety glasses as well as some steel toed boots. It's also recommended that you use ear plugs or muffs and a face mask that helps protect you from dust that flies in the air while grinding.
3. When turning on the bench grinder stand to the side and allow the grinder to run until it's at maximum speed. You are now ready to begin using the grinder.
The Best Way To Use Your Bench Grinder
When you begin working a piece of metal with the grinder you should place it on the tool rest and begin to push slowly until it touches the edge. The metal shouldn't touch anything but the grinder. You shouldn't allow it to touch the sides of the machine.
Anytime that the metal becomes too hot then you should place it into the water that you prepared before you began. You will want to make sure not to put your face in a position where the steam can come back on your face as it could burn you. As the metal is hot you also need to handle it correctly so that you don't burn your hand.
If you want to grind a piece of metal off of the object you simply move it back and forth across the grinder until it's been removed. If you hold something on the grinder in one place without moving it for too long it will cause it to heat up quickly. If this happens it can sometimes damage the peace.
When you're trying to shape a piece of metal you use a similar action as when grinding it. You use a back-and-forth motion across the wheel. Anytime you see the metal turning orange it has become hot and you should pull away from the grinder. Once you get the metal in the right shape then you'll need to dip it into the water and allow it to cool.
When sharpening a blade you will need to hold it securely using both of your hands. You'll push the blade at an angle to the grinder and you'll use an up and down motion so that the grinder is able to sharpen the edge. By moving the blade back and forth you keep it from becoming too hot and it also will prevent the grinder from cutting it and damaging the blade.
