The other way to tell if your bar is bent is to remove the bar from your chainsaw, then lay the bar on a flat surface to notice any bends. If you are not sure which bar is compatible for with your chainsaw, check out our step by step guide on how to buy the right chainsaw bar. Unless a chainsaw bar becomes bent or damaged, a chainsaw bar could outlast the chainsaw itself.
A crooked cut can be caused by uneven bar rails, uneven sized teeth on left and right side of chain, a slanted bar slot, uneven sharpness of left vs right teeth, a twisted bar, or a combination of any or all of the above. A slopppy fit of the chain in the bar groove by itself shouldn’t cause the cut to go to one side or the other. A bar groove too shallow will quickly ruin the drive links on the chain.
If the bar you are using has significant heel wear, your saw probably has a tendency to “Throw” its chain. If you compare a worn bar to a new bar, you will notice the warn bar has a much narrower heel. To inspect a guide bar for damage, first remove it from the saw.
One of the less obvious aspects of chainsaw maintenance is proper inspection and management of the chainsaw bar. If you discover that your bar rails are worn down unevenly, it’s time to replace the bar. If your bar has lost its characteristic u-shape, it’s time to replace the bar.
how to know if chainsaw bar is bad Related Question:
Does a chainsaw bar wear out?
As a chainsaw bar wears out, you’ll lose cutting accuracy and efficiency. If the same type of cuts that your saw used to breeze through are now taking twice as long, and you’re sure that your chain is sharp enough, you might look at how worn your bar has become. Thankfully, there are a few simple ways to check this.
How long should a chainsaw bar last?
Re: how long does a bar last The next, a Granberg, lasted about 2 months. About that time Stihl started using them with the same results. A good bar can be filed a few times on both sides and the tip replaced when needed. They could last almost as long as the saw.
Why would a chainsaw cut crooked?
Uneven top plates can cause a chain to cut crooked. It’s important to keep all top plates equal length. Dull cutters damaged by rocks can cause a chain to cut crooked. It’s important to remove all damage from cutters prior to cutting.
What causes chainsaw bar wear?
The opposing surfaces inside the rails are parallel with each other. During use, the chain’s drive links rub against these “walls,” causing wear. Bars tend to wear fastest in the top of the groove, slowly turning what was once a “U” shaped groove into a looser “V” shape.
How often should you flip the bar on a chainsaw?
Some professional loggers would advocate that you should flip your chainsaw bar at the end of every use, particularly when you are cleaning up. Others suggest a more relaxed approach advising that you flip the chainsaw bar only when you are changing your chainsaw blade.
Can a bent chainsaw bar be straightened?
Solid body bars with replaceable noses can be straightened by hammering with the bend peak up on a flat anvil. Laminated bars need a piece of rubberized belting of approximate 1/4″ thickness between bar and anvil to properly hammer straighten .
Can you drill holes in chainsaw bar?
Re: Drilling a Chainsaw Bar Drilling that bar may not be as difficult as you think. It will be best if you use a drill press, start with a pilot hole, and then drill to the size you need. Make sure you have a sharp bit, run at the lowest speed you can, and use cutting fluid.
Why is my chainsaw burning the wood?
Your chainsaw burns wood because of poor lubrication Lubrication allows the mechanical parts to coordinate much better by avoiding a phenomenon of friction which risks causing traces of burns. This is one of the main reasons that your appliance gives off too much heat and that the wood burns.
How many times can you sharpen a chainsaw?
Cutters can be sharpened up to 10 times or more before the chain needs replacing. If your cutters are worn unevenly after a few sharpenings, a professional can regrind them to uniform shape. If you use the same chain for a few years, then buy a new one, the new one won’t mesh smoothly with the sprocket and bar.
How do you fix uneven wood cuts?
Usually, the fixing method is to fill the gap with lots of glue and wood filler. But here’s a better method, take a small piece of wood and put it in the gap. Then glue it in the right place and clamp it to the side of the tenon. Make sure that you have arranged the grain of the wood.
When should a chainsaw chain be replaced?
Once the wear markers have been met it’s essential to replace the chainsaw chain. Filing past the wear marker will greatly reduce the chain’s cutting performance, and increases the risk of the tooth breaking off. Ideally you should reach the tooth and depth gauge markers at roughly about the same time.
Why does my chainsaw bar keep bending?
A saw that has had one side of the chain nicked on a rock or dulled in the dirt will cut in a circle. A chain that has been sharpened differently on one side of the chain than the other will cut in a circle. A bent bar might cut crooked or straight, but, it will get hung up in the kerf.
Why do loggers Run chainsaw bars upside down?
Every chainsaw bar has been designed to be mounted right-side up or upside down. The reason for this is that it allows the user to extend the life of his chainsaw bar by 50%. Flipping the bar will give the heavily-used areas some relief from wear and tear.
Why does my chainsaw blade dull so quickly?
Is the wood that you’re cutting with the chainsaw particularly dirty? Many chainsaw enthusiasts have noted that their blades dull faster when they’re cutting muddy wood. If the logs that you’re cutting up are muddy, then perhaps that is the sole reason why your blade is dulling too fast.
What chainsaw chains do professional loggers use?
Full-chisel teeth chains are usually used by professionals on large saws. Semi-chisel teeth are rounded, so the risk of kickback is less, and they stay sharper longer. Semi-chisel teeth cut slower but are a better choice in dirty wood than full chisel.
