Put the tools in your oven - not too hot just set your oven to degrees and let the tools sit inside for 2 hours. This treatment will help prevent cracking when being sharpened. Use the edge of the grinding wheel to make short work of the mushroom look, then start on the tip.

Take your time and do several passes. You need to be careful of any red hot pieces of metal that will come off as you grind away. Make sure you keep dipping it in cool water, oil or some other cool lubricant.

Adjust the tool rest till you get the wheel to the middle of the bevel. Follow the shape of the edge. The angle-adjustable eye shields work well to protect your eyes from debris, and the one three times magnifying also gives you a clearer view.

The two are 60 and grit wheels. Since handling bench grinders come with a considerable risk of bodily harm, safety features are also a big part of this machine. The safety shields on the wheels keep your eyes safe from any debris and allow you to view your work from a safe distance, the wheel guard helps prevent accidental contact with the grinding wheel, and the spark deflector reduces the number of sparks spraying back towards you.

With the right knowledge, you can pick the best bench grinder for you within your budget. Below is a comprehensive analysis on how to choose the best among many. Higher speed grinders have high inertial and are used to remove large amounts of material faster, which means that they also generate large quantities of heat almost immediately you start working, which can be problematic for sensitive metals.

Slow speed bench grinders run at lower speeds and generate less heat. This speed makes them better if most of the work you plan to do is sharpening as the edges are thin and can quickly overheat. Unlike high-speed grinders, which quickly take large amounts of material off the workpiece, slow speed grinders take material off slower. Hence you can better control how much material to take off. This slower pace is ideal for delicate pieces and is more forgiving of small errors while grinding. Another advantage of a slow speed bench grinder is that it often comes with friable white grinder wheels of better quality and grind better than the gray grinder wheels that come with high-speed grinders.

As useful as a bench grinder is, it also comes with a considerable risk of bodily harm if mishandled. Hazards that could arise from using a bench grinder include respiratory problems from dust, impact injuries from flying objects, wheel explosions, sparks, and heat hazards. A bench grinder is a tool which spins grindstones, and these grindstones gently shape metal.

They can quickly sharpen blunt tools. Most bench grinders run at about 3, rpm, although there are more and more variable speed grinders on the market these days. However, for sharpening blades, a low-speed grinder running at 1, rpm is a much better choice. A lower speed reduces the chance of the edge of your tool overheating. Slow speed grinders do still generate heat, but it happens at a more controllable pace that is ideal for work on delicate metals. This is what is required for sharpening work because the edges of cutting tools are very thin and can overheat easily.

With a slow speed grinder and some practice you can learn to sharpen just about any cutting tool without ruining the hardness of the blades. Slow speed grinders tend to cost a bit more because they need better motors.

Slow motors need to have more power and torque to overcome lower inertia and possible stalling during the grinding process. If the motor on your bench grinder is under 1HP you should be able to control the speed with a router speed control. My experience with this kind of set-up,however, is that when the speed is lowered, it loses its steady rhythm and jerks between 90 and RPM. You can slow down your bench grinder by fitting a belt pulley in the place of the wheel. You can then fir a V belt to a secondary shaft with a larger pulley wheel.
