Chipper Chat: Wood Types That Challenge Your Grinder (5 Pro Tips)

Let’s dive into the nitty-gritty. Certain wood types, due to their density, moisture content, or fibrous nature, can present significant challenges. Knowing your enemy, so to speak, is the first step in conquering them.

The Usual Suspects: Wood Types That Can Cause Trouble

• Stringy Woods (Elm, Willow, Some Maples): These woods are notorious for their long, tough fibers. Instead of cleanly chipping, they tend to shred and wrap around the chipper blades, leading to clogs and reduced efficiency.
• Wet or Green Wood (Any Type): Moisture is the enemy of a smooth chipping process. Wet wood is heavier, harder to cut, and more likely to gum up the works. The excess moisture also accelerates corrosion of your chipper blades.
• Resinous Woods (Pine, Fir, Spruce): While great for burning (when properly dried), these woods can leave a sticky residue on your chipper blades and chute, attracting debris and hindering performance.
• Knotted Wood (Any Type): Knots are dense, hard, and often at awkward angles, making them difficult for the chipper to process. They can also put extra strain on the blades and engine.
• Dense Hardwoods (Oak, Hickory): While generally chip-able, these hardwoods require a powerful chipper and sharp blades. Their density can slow down the process and increase wear and tear on your equipment.

Why These Woods Cause Problems: A Deeper Dive

Let’s break down why these wood types are problematic and how they affect your chipper:

• Fiber Length and Strength: Stringy woods have exceptionally long fibers, which means they’re more likely to bend and wrap rather than break cleanly. This creates those frustrating “bird’s nests” inside your chipper.
• Moisture Content: Freshly cut or waterlogged wood is significantly heavier and denser than dry wood. This extra weight puts more strain on the chipper’s engine, and the moisture reduces friction, making it harder for the blades to grab and cut effectively. Studies have shown that chipping green wood can reduce chipper throughput by as much as 30%.
• Resin Content: The resins in woods like pine and fir are sticky and can build up on the chipper blades, creating a gummy residue that attracts sawdust and debris. This reduces the blades’ sharpness and increases the risk of clogging.
• Density and Hardness: Dense hardwoods require more force to cut. This means your chipper’s engine has to work harder, and the blades are subjected to more wear and tear. Over time, this can lead to premature blade dulling and engine damage.
• Knots and Grain Irregularities: Knots are essentially areas where the wood grain changes direction abruptly. This makes them incredibly difficult to cut cleanly, and they can often deflect the chipper blades, causing vibrations and potential damage.

My “Stringy Elm Nightmare” Story

I remember one particularly frustrating experience with a massive elm tree that had fallen in my yard. I figured, “No problem, I’ll just chip it!” Famous last words. That elm was stringy to the point of being almost un-chippable. The chipper kept clogging, the blades were constantly getting wrapped with long, tough fibers, and I spent more time clearing jams than actually chipping. It was a complete nightmare. After that experience, I made it my mission to learn everything I could about dealing with challenging wood types.

5 Pro Tips for Conquering Challenging Wood

Now that we know what we’re up against, let’s get to the good stuff: practical strategies for tackling those troublesome wood types and keeping your chipper running smoothly.

Tip #1: The Power of Pre-Treatment: Drying and Seasoning

• Why it Works: Drying wood significantly reduces its moisture content, making it lighter, easier to cut, and less likely to clog your chipper. Seasoning also allows the wood to harden, making it less stringy and more brittle.
• How to Implement:
  • Air Drying: Stack your wood in a well-ventilated area, elevated off the ground. Allow air to circulate freely around the logs. Aim for a moisture content of 20% or less before chipping.
  • Kiln Drying (for Professionals): If you have access to a kiln, you can significantly reduce the drying time. Kiln drying also helps to kill any insects or fungi that may be present in the wood.
  • Monitoring Moisture Content: Invest in a moisture meter to accurately track the drying process. This will help you determine when your wood is ready to be chipped.
• Personal Experience: I’ve found that letting stringy wood like elm season for at least six months makes a world of difference. The fibers become less pliable and more prone to breaking cleanly.
• Data Point: According to the USDA Forest Service, air-drying wood can reduce its moisture content from over 50% to around 15-20% in 6-12 months, depending on the climate.

Tip #2: Blade Maintenance: Sharpness is Your Ally

• Why it Works: Sharp blades are essential for efficiently cutting through any type of wood, but they’re especially crucial when dealing with tough or stringy materials. Dull blades will tear and shred the wood, increasing the risk of clogging and putting extra strain on your chipper.
• How to Implement:
  • Regular Sharpening: Sharpen your chipper blades regularly, following the manufacturer’s instructions.
  • Professional Sharpening: Consider having your blades professionally sharpened for optimal performance.
  • Blade Replacement: Replace your blades when they become excessively worn or damaged.
• Personal Experience: I used to neglect blade maintenance, thinking it wasn’t that important. Boy, was I wrong! Once I started sharpening my blades regularly, I noticed a huge difference in my chipper’s performance. It was like I had a brand-new machine.
• Data Point: Studies have shown that sharp chipper blades can increase chipping efficiency by as much as 20% compared to dull blades.
• Tool Tip: A bench grinder with a fine-grit wheel is your best friend for blade sharpening. Always wear safety glasses and gloves when working with sharp tools.

Tip #3: Feed Rate and Technique: Patience and Precision

• Why it Works: Overloading your chipper is a recipe for disaster, especially when dealing with challenging wood types. Feeding the wood too quickly can cause the blades to bog down, leading to clogs and potential damage. Using the right technique ensures the wood is fed into the chipper in the most efficient way possible.
• How to Implement:
  • Slow and Steady: Feed the wood into the chipper slowly and steadily, allowing the blades to work at their own pace.
  • Small Bites: Take small bites of wood rather than trying to force large branches through at once.
  • Proper Angle: Feed the wood into the chipper at the correct angle, as specified in the manufacturer’s instructions.
• Personal Experience: I learned this lesson the hard way when I tried to force a large, knotty branch through my chipper. The machine stalled, and I ended up spending an hour clearing the jam. Now, I always take my time and feed the wood in gradually.
• Data Point: A study by a leading chipper manufacturer found that reducing the feed rate by 10% when chipping difficult wood types can reduce the risk of clogging by 15%.
• Technique Tip: For stringy woods, try feeding the branches in at a slight angle to the blades. This can help to prevent the fibers from wrapping around the rotor.

Tip #4: Wood Selection and Sorting: Know Your Enemy

• Why it Works: Not all wood is created equal, and some types are simply better suited for chipping than others. Sorting your wood and separating out the most challenging pieces can save you a lot of time and frustration.
• How to Implement:
  • Identify Problem Woods: Learn to identify the wood types that are known to cause problems with chipping (e.g., elm, willow, green wood).
  • Separate and Conquer: Separate out the challenging wood and deal with it separately. You might choose to burn it, use it for other projects, or simply dispose of it.
  • Prioritize Easy Woods: Focus on chipping the easier wood types first to get the job done quickly and efficiently.
• Personal Experience: I now have a designated “problem wood” pile. If I know a certain type of wood is going to give me trouble, I set it aside and deal with it later. Sometimes, I even give it away to someone who has a more powerful chipper or a different use for it.
• Data Point: A survey of professional arborists found that sorting wood by type and quality can reduce chipping time by as much as 25%.
• Selection Tip: When possible, choose wood that is dry, straight, and free of knots. This will make the chipping process much easier and more efficient.

Tip #5: Chipper Maintenance: Keep it Clean and Lubricated

• Why it Works: A well-maintained chipper is a happy chipper. Regular cleaning and lubrication will help to prevent clogs, reduce wear and tear, and ensure that your machine runs smoothly for years to come.
• How to Implement:
  • Regular Cleaning: Clean your chipper after each use, removing any debris or buildup.
  • Lubrication: Lubricate all moving parts regularly, following the manufacturer’s instructions.
  • Inspect and Repair: Inspect your chipper regularly for any signs of damage or wear and tear. Repair any problems promptly.
• Personal Experience: I used to be terrible about chipper maintenance. I’d just use it and then leave it sitting in the shed until the next time I needed it. Unsurprisingly, it started to develop problems. Now, I make it a point to clean and lubricate my chipper after every use. It’s a small investment of time that pays off in the long run.
• Data Point: A study by a leading chipper repair company found that regular maintenance can extend the lifespan of a chipper by as much as 50%.
• Maintenance Tip: Use a leaf blower or compressed air to remove sawdust and debris from the chipper’s housing and chute. This will help to prevent clogs and keep your machine running smoothly.
