How to use an electric chainsaw sharpener

All cutting tools need to be sharpened after a while of using it, and there’s no better tool for this than an electric chainsaw sharpener. This is a very useful tool and easy to handle, also the best part is that you can sharpen anything by yourself than expending money in a professional.
An electric chainsaw sharpener are use to sharp every teeth of the chainsaw blade, with it you can set the correct depth and angle; the tool has unique adjustments to sharpening the teeth perfectly.
Use it and save money!

What you need first

Before doing anything you must look for the chainsaw specifications, not all of them require the same depth. The next thing is choosing the electric chainsaw sharpener, and also the chainsaw blade.

Instructions

• Read the specifications of the chainsaw this way you’ll know how to use the electric chainsaw sharpener correctly in the blade. Look in the box or package in which the blade comes.
• Place the electric chainsaw sharpener in a firm ground so it doesn’t move while you’re working. This way you can install, reach and remove easily the blade from the machine.
• Now it’s moment to install the proper sharpening stone with the correct width (it’s common that the width is 3/16 inch) and that fits in the gap between the teeth. You can find different sharpening stones with diverse width, so look the one that you need.
• Put the blade in the sharpener’s holder and set the swivel angle for the blade. The common swivel angle must be 0 degrees to 60 degrees. The adjustment it’s on the rear of the tool.
• Regulate the angle for the blade tooth; adjusting the angle is what gives the perfect curve in the teeth that let cut the wood. Loose the knob under the blade holder and move it to positive or negative directions of 10 degrees (don’t forget the specifications).   
• Then set the blade tooth backstop and lower the grinding wheel into the teeth. Set the backstop so you try a few teeth; adjust this backstop so all of the teeth of the blade rest under the grinding wheel.
• Set the depth stop of the grinding head and it must fit into the teeth. Don’t take too much of the metal because can overheat the metal and loose its temper. Try that the grinding wheel only touches the inside edge of the tooth.
• There’s going to be an amount of sparks when you start touching the first tooth of the wheel with the grinder, look inside the tooth by lifting the wheel. You must see a curve in the tooth with a shiny metal look. Then sharp the next teeth.
• Reset the blade tooth angle (just like Step 5) so you can adjust the grinder for the next set of teeth in the chainsaw blade. If the first time that you set the angle has a positive 10 degrees you’ll have to set it in a negative 10 degrees for the opposite set of teeth.
• So, work continuously until all the teeth have the full curve and the shiny metal look. 

The ultimate guide of battery powered tools

The battery powered tools are generally known as cordless electric devices that are power-driven by a battery pack, this cordless tools operates without a power cable, this sometimes can be attached to an electricity supply or a generator or other kind of power source.
These reasons are why this battery powered tools has a great mobility, the technology advances had improved more potent rechargeable batteries.

Save money

Powered tools are a good investment, but you also can find expensive rechargeable batteries, there’s power tool batteries brands that can often cost as much as the tool itself, especially the models that change in time.

Rechargeable batteries characteristics 

If you’re planning to buy a battery powered tool you must become well-known about the characteristics of this kind of tools. The essential elements that you must know after buying one of this it are what affect the battery’s life.

So, let’s check these characteristics, so you’ll know how much will the battery last:

• Cycle life: the complete life of the battery it’s expressed as the quantity of charge cycles, this mean that works until the ability of transfer energy is lost. All batteries don’t last forever (although they can wear out for different reasons).
• Depending on the battery type and the use of the battery it’ll run out completely. 
• Self-discharge: if you don’t use the battery the charge will be lose, and there’s batteries that run out faster than others. Depending on how many times you plan to use the powered tool, you can choose what kind of self-discharge rate is good for the battery that you’ll going to buy.
• Voltage: this characteristic is what determines the power quantity that a battery can deliver, in other words, higher voltage more power.
• Run time: this is the time’s capacity that a battery can handle between charges, it’s also known as the amount of amperage hours (AH) that can provide. More simply, this is how much energy a battery can hold. Remember, higher AH means the lengthier battery between charges. 
• Deep discharge: this means that a battery will run out completely trough normal operation. For some batteries this mean problems and for others don’t, deep discharge can significantly decrease the cycle life and capacity. Some brands need a deep discharge regularly to keep them healthy.
• Memory effect: the memory effect occurs when a battery is recharged several times without being deep discharge it. There’s battery that can “remember” how much had been recharged, so then can accept a shorter charge range as new energy capacity.

Power tool batteries types

• Nickle Cadmium (NiCd): this is the toughest design, they’re famous because is also the oldest in the market, known for being inexpensive and with a long cycle life. 
• Nickle Metal Hydride (NiMH): this a newer battery, better than a NiCd in different ways, such as less toxicity to the environment, better capacity (it can be two to three longer than NiCd’s), but are sensitive to storing and charging conditions. 
• Lithium Ion (Li-Ion): like NiMH possess a newer technology, it’s the best choice because it surpass all characteristics in compare with other types. The downside is that is more expensive and the heat faster when using or charging and this can be a risk; they don’t have memory effect, so they wear out for using.   

How to sharpen your Chainsaw

Picture from  toolstop

Chainsaws are powerful and efficient tools that can make accurate cuts in short time, these tools posses an engine that drive a chain around a guide bar. The chain has different blades attach that perform its useful cutting.
Now, let’s remember that the ability to cut wood its for the blades sharp. A cutter is made up of two essential parts: the first is a flat-faced depth gauge that works for the depth’s control and a second one a dual-profile cutting element. These couple of parts are mentioned by professionals: as top plate and side plate possess three different angles.
If the chainsaw is used several times the blades can turn worn and dull (if this, the tool won’t cut straight), in this moment you’ll need to sharpen the chainsaw. Sharpen the blades makes the chainsaw safest when using it.
The chainsaws are manufactured with cutting chains for easy maintenance, this article is all about how to sharpen a chainsaw, so let’s get started:

• Determine the size of the saw’s chain; you’ll need a rotary grindstone or a chainsaw file that matches the chain tooth. There are three different sizes of chainsaw teeth’s (3/16 – 5/32 and 7/32 of an inch), the diameter of your saw must be exactly as the grindstone or file. 
• Use mineral spirits or degreasing detergent so you can clean the chain completely, remove all the oil, debris and dirt from the chain. It’s not recommended to do an excessive cleaner in the engine and other parts because can damage the chainsaw.
• The teeth can get chipped, broken or bent so inspect them so you can determine the damage. The top plate should be at least ¼ inch in length, any shorter than this it can make that the cutting tooth breaks.
• Put your saw in a solid surface, it’s important that the saw be steady, the blade must be stable for a safety filing. So, clamp the bar in a vise, with the jaws holding the bar the chain can rotate easily.
• Place the leading cutter at the start point. This is going to be the shortest cutter on the chain, if the cutter have the same length start filing anywhere, and focus that each cutter that the flat edge on top of each cutter are virtually the same length. 
• Set the angled “tooth” in your file in the notch on the front, the curve of the file must correctly fit the curve of the face of the cutting tip, and don’t forget, the top of the file diameter needs to be above the top of the tooth.
• Hold the file at the same angle that the cutter was placed in the beginning, this angle should be 25 – 30 degrees, look for the saw specifications, there are chains that have a flatter angle. Be aware that you must match the angle of the chain that was originally machined to.  
• Slide the file trough the face of the cutter, twist it, but not too much, with this you can discharge metal chips that are removed. You can push the file from the short side of the angle into the long point. Think in letting a smooth cutting surface.  
• It’s important that you work every second tooth just like the start point around the loop. While you progress through the chain keep working by hand so the teeth you’re filing is on top of the bar.
• Reverse the side of the chainsaw and keep the work around the unfiled teeth angled in the opposite direction. And keep an eye on the length of each flat top of the cutter, you can use the caliper so the “bite” be equal. 
• Remember to check the depth gauge; this need to be cleared and the curved hook shaped link must be between the cutters. If the depth gauge is too high you need to file it.
• File all raker that sits too high, for this you can use a flat mill bastard file.
• And last, oil that chain, check the tension and the chainsaw will be ready to work already.
