Why Is My Bandsaw Burning The Wood: Where There’s Smoke, There’s A Problem

Woodburning is delightful, but not when it’s an accident, especially when you’re using a saw. If you find your boards smoking and you’re wondering why your bandsaw is burning the wood, you have a simple issue. So long as it is truly the wood and not the saw making the smell, you have a common blade issue. People often forget to change, or in some cases, sharpen their saw blades. A sharp blade cuts. Unfortunately, a dull blade isn’t cutting or ripping so much as it’s rubbing its way through your wood. Have you ever seen one of those old-fashioned fire starters that involves two sticks and friction? You can do the same trick with a dull metal saw blade. After burning a few boards, I learned to keep an eye on my bandsaw blades. I’ll teach you everything I know about bandsaw blades and removing burn marks. A little prevention can save you a lot of headaches.

Why is my bandsaw burning the wood? Your bandsaw is burning the wood because it’s too dull to be efficient. In order to get clean cuts in wood, you need a sharp blade. Friction causes burning, and a dull blade has more surface in contact with your boards. Hence, more friction, the result of which is that you burn the wood as you cut it. 

How Do You Get Rid Of Saw Burns On Wood

When you find your bandsaw is burning the wood, you need to change out the blade immediately. Sadly, that won’t fix the burns you already have. The good news is that you can get rid of burn marks without scrapping the wood in most cases. The list below includes all the best ways to get rid of burn marks.

Options For Removing Burn Marks From Wood

  1. Prevent burns from happening by changing your blade. Make sure you’re using the right tooth pattern for the type of wood you are cutting.
  2. Grab some sandpaper or a hand sander. You can buff off shallow burn marks easily. Doing this leaves new, unburnt wood exposed.
  3. Use a planer to get rid of deeper burns. When you take thin slices of wood off the surface, you are removing the burnt section.
  4. A sharp scraper works well for small burn marks. However, you may need to sand the surface when you finish.

You can use any or all of these methods to salvage your burned boards. When the burns are deep, start with a scraper or planer. However, for shallow surface burning, a little sandpaper will do the trick quickly.

Why Is My Saw Blade Smoking

The most common reason for a smoking blade is a dull edge. The extra friction from dull teeth coming in contact with more of the wood creates heat. When you get sawdust and motion, it makes smoke or even fire.

When this happens, stop immediately. Change your saw blade and get rid of the old, dull blade. If you have a proper setup and a high-quality bandsaw, you shouldn’t have the problem again.

Milwaukee’s Bandsaw from Amazon is a superb cordless option from a trusted brand. This portable bandsaw is among the lightest yet most efficient bandsaws available at a mere seven-point six-seven pounds. Best of all, this saw is more powerful than you’d expect, even slicing through metal. Read the outstanding reviews when you click here.

Is It Possible For A New Bandsaw Blade To Burn Wood

Although it’s uncommon, a new bandsaw blade can burn wood. I will explain how and why your brand new, sharp bandsaw blade can cause this problem. The good news is that it’s not the blade at all.

Friction always creates heat. A bandsaw that is set wrong can move too fast, so a mechanical malfunction could be to blame. More likely, there’s a buildup of resin and sawdust.

The small particles and flammable resin are heating up, and that means smoke. Stop before there’s a fire. You can switch to a blade with a different tooth pattern, such as a skip blade, to remove more sawdust as you cut. Make sure your boards don’t end up too covered in the small flammable buildup from cutting, and you should be fine in the future.

When you need a reliable bandsaw, grab this DeWalt 20V Max Portable Band Saw. The dual-bearing blade guide rollers help you make smooth cuts at home or on the go. Moreover, the ergonomic and centered handle position offers both balance and reduced hand fatigue as you work. Plus, the LED work light has a twenty-second delay, so it doesn’t shut off the second you stop cutting. To have Amazon deliver to your door, click here

What Is The Best Bandsaw Blade For Wood

The best bandsaw blade for wood depends on the type of wood you’re cutting and the desired outcome. No bandsaw blade should burn wood no matter what you’re cutting. When you choose the right, sharp blade you can easily slice any board.

Blades come in four main varieties, standard, skip, variable, and hook. The length and width of your blades will depend on your particular saw. Each type does a different job. The spacing, style, and the number of teeth per inch determine how the blade cuts.

According to Wood Magazine, standard blades are made to cut thin, delicate materials, and narrow curves. Typically these are less than a five eights radius. It would be best if you use a one-eighth or three-sixteenths inch10–14-TPI standard-tooth blade.

Larger curves are best with a standard or skip-tooth blade. The skip tooth style also helps you remove more sawdust as you cut. Additionally, choose a skip tooth blade in the largest size possible for green wood. Alternately, a super-dense hardwood needs a carbide-tooth blade because it is stronger than most other varieties.

Resawing works best with a variable or skip blade. Pick the widest one your saw can handle for the best results. Meanwhile, standard or hook tooth blades work well for crosscutting and ripping.

When Should I Change My Bandsaw Blades?

Always change a dull bandsaw blade. When it starts burning the wood, it’s easy to tell your bandsaw blade is dull, but there are other signs. Unfortunately, because people work at different rates, there’s no single timeframe for changing blades.

By paying attention to how your saw looks and works, you’ll be able to tell when it’s time for a change. I’ve outlined the most common indicators other than burnt wood, so you know what to look for.

Noise

All saws make noise when you work. That is a normal part of cutting. However, a dull bandsaw blade will often make more noise than usual. When your bandsaw gets excessively loud or becomes squeaky, you have a problem.

Teeth

Metal is incredibly strong and durable, but it doesn’t last forever. It is normal for saw blade teeth to show some signs of wear as you use them. That said, too much wear is bad.

When your saw blade teeth have become rounded or lost their sharpness, then it’s time for a change. Cutting requires a sharp edge. When the teeth get too dull, they are pressing and ripping more than slicing.

Movement

Does your bandsaw cut a smooth, easy line right through the wood? You shouldn’t need to force wood past the teeth. Moreover, the cuts should be straight and even. If your blade is acting up, you need to change it.

More importantly, a blade that isn’t cutting straight is a danger. Beyond merely making a mess or costing you good wood, a wobbly blade can hurt you. Check to make sure it’s seated properly and locked in place. If it is, but you still get uneven lines, change that blade.

Cracks & Damage

Wood may burn, but as metal heats, it changes as well. You may start to see cracks in the blade. This is a result of stress from heating and cooling repeatedly.

A little warmth is normal, and blades tolerate it just fine. However, those dull teeth create excess friction, which means the blade is getting too hot. Even if the wood doesn’t burn, your blade may take damage over time and start to show tiny cracks.

In this case, switch the blade right away. A cracked blade could break and go flying at any moment.

I recommend an Anbull Portable Band Saw with Removable Alloy Steel Base for easy blade changes and cutting. The bright LED spotlight will show you how fast and efficient this saw is as it cuts up to five point-eight feet per second. Mount it to the base for stable tabletop cutting, or take your saw anywhere you need it. Better still, there are three different saw blade options for more versatile cuts.

Final Thoughts

Burning wood is for artisans and campers. If it is happening in your cutting process, I hope you’re using a laser instead of a bandsaw. Otherwise, switch your blade for a sharper one to get a clean, burn-free cut.

Some other things can cause burning as you cut. For example, dirt, sawdust buildup, or pitch can all create undue friction. Anything creating more surface to rub against is a fire hazard where wood and high-speed saws come together. A little clean-up can often resolve lingering wood-burn issues.

Take the time to maintain your bandsaw blades properly and pay attention to build up as you work. Sometimes the solution is quite literally under your nose if you know where to look.
