Simon is going to be making a series of videos and blogs to share maintenance tips with other chainsaw carvers. We kick that series off this week with this blog about carving bar maintenance for chainsaw carvers…
What Is a Chainsaw Bar?
For readers who aren’t regular chainsaw users, the bar has the vital job of guiding the chain – the part that does the cutting! Bars come in different lengths, and there are a few different types serving different purposes. For example, a standard bar with a fixed nose sprocket is good for light gardening. Carving bars are special Stellite bars with a smaller nose radius that minimises the possibility of kickback. Maintaining the bar well preserves the life span of not just the bar, but also the chain. It is also a good health and safety practice, as well maintained equipment equals less opportunity for accidents.
Carving Bar Maintenance for Chainsaw Carvers Tip One: Filing
The first tip involves the bar rails. The bar rails enclose the groove along the edge of the guide bar, and that groove is the channel the chain runs along. With time and use, those bar rails can crack, chip, or become sloped. This can particularly happen if the chain is too slack and ‘clacks’ against it.
If the bar is no longer flat, it causes the tie strap on the chain to wear out. This in turn compresses the metal and causes what fellow chainsaw carver Mick Burns calls ‘stiff-slack’ syndrome. The result of this is a snapped chain!
So not only does good carving bar maintenance preserve the life of the bar, it preserves the life of the chain too.
The solution to this is maintaining its shape.
Check the bar each time you use it, and if you notice signs of wear and tear or a shape change, file it flat again. A vice may help you hold it in place while you file, and ensure you keep them parallel. Simon uses a diamond file from ChainsawBars.co.uk who sell a range of bar maintenance tools. They also have a fantastic selection of chainsaw bars and a loyalty scheme. They’re definitely one of Simon’s recommended resources!
Carving Bar Maintenance for Chainsaw Carvers Tip Two: Cleaning
The second tip for effective carving bar maintenance is to make sure you clean it well.
This means regularly cleaning all dirt and debris from the bar and the bar groove. If you have bar groove cleaner and compressed air, this will give you the best results. There are also tools available, although you can still do a good job with a simple rag.
This is important because if a bar isn’t clean, it won’t oil well, and oil is key to cooling it down. In turn, a cool bar is key in the bar keeping its shape.
As with filing, ChainsawBars have a range of products for cleaning, and also have a series of videos with maintenance tutorials. You can find the video about cleaning bars HERE.
Carving Bar Maintenance for Chainsaw Carvers Tip Three: Appropriate Use
Simon’s final tip for carving bar maintenance is a preventative one. Use it for its correct purpose!
As was mentioned in the description of chainsaw bars, carving bars are designed for the purpose of creating detail or improving performance in high-precision jobs. If they are used for big cuts and massive pieces of timber, they will soon pick up cracks and lose their shape. If you are making big cuts, Simon suggests it’s best to stick to a standard bar.
And if you are starting out and don’t want to invest in lots of equipment, don’t worry. In our blog about “Basic Kit for Starting Chainsaw Carving“, Simon recommends starting with a standard bar anyway!
More About Carving Bar Maintenance
If you are interested in knowing more, Simon also made a video with more detail about basic carving bar maintenance for chainsaw carvers. It’s about eight minutes long, and well worth the watch if you would like to better understand your equipment and how to preserve it. You can watch it below, or find it on his YouTube Channel, Simon O’Rourke.
