The LT15: A Deep Dive
The Woodmizer LT15 is a band sawmill designed for processing logs into lumber. Its key feature is its portability; it can be easily transported to the log source, reducing the need to haul heavy logs. It’s also known for its simplicity and relatively low cost compared to larger, industrial mills.
Key Specifications and Technical Requirements
| Specification | Description |
|---|---|
| Max Log Diameter | Typically around 28 inches (71 cm). This can vary slightly depending on the specific model and any aftermarket modifications. Note: While you can technically mill larger logs with some creative maneuvering, exceeding this limit significantly reduces efficiency and increases the risk of blade damage. |
| Max Log Length | This depends on the bed configuration. Standard sections are typically 20 feet (6.1 meters). Bed extensions can be added to accommodate longer logs. I’ve milled logs up to 30 feet long using extensions, but handling those behemoths requires careful planning and support. |
| Engine Options | Available with either a gasoline engine (typically around 25-27 horsepower) or an electric motor. The gasoline engine offers portability, while the electric motor is quieter and more efficient for stationary setups. My personal preference is the gasoline engine for its flexibility, but I always make sure to use premium fuel and change the oil religiously. |
| Blade Size | Typically uses a 1.25-inch wide band blade. Blade thickness and tooth pitch are crucial for different wood types. I’ve found that a 0.045-inch thick blade with a 7/8″ tooth spacing works well for most hardwoods, while a thinner blade (0.042″) with a tighter pitch is better for softwoods. |
| Cutting Capacity | Varies depending on the blade and wood type. Expect to cut approximately 100-200 board feet per hour with proper technique and a sharp blade. This is just an estimate. I once milled 300 board feet of pine in an hour, but I was pushing the mill to its limit and probably shortened the blade’s lifespan. |
| Bed Construction | Typically constructed from heavy-duty steel. The bed needs to be level and stable for accurate cutting. I highly recommend investing in a good set of leveling jacks to ensure the bed is perfectly flat, especially if you’re setting up on uneven ground. |
| Weight | Varies depending on the engine and bed configuration, but typically weighs between 1,500 and 2,000 pounds (680-900 kg). This is a significant weight, so make sure you have a suitable trailer and tow vehicle if you plan on moving the mill frequently. |
| Price | New LT15s typically range from $10,000 to $15,000 USD, depending on the options and features. Used models can be found for significantly less, but be sure to inspect them thoroughly before purchasing. I bought my first LT15 used, and it was a great deal, but it required some serious TLC to get it running smoothly. |

Woodmizer is constantly refining its products, and the LT15 is no exception. Here are some of the notable new features that have been introduced in recent models:
- Accuset 2: This computerized setworks system automates the blade positioning, allowing for more precise and consistent lumber dimensions. I’ve used Accuset 2 on a larger mill, and it’s a game-changer for productivity and accuracy. It essentially eliminates guesswork and reduces waste.
- Improved Blade Guides: The blade guides have been redesigned for better support and stability, reducing blade flutter and improving cutting accuracy. Blade guides are often overlooked, but they’re crucial for maintaining a straight cut. The new design seems to be more robust and less prone to wear.
- Enhanced Lubrication System: The lubrication system has been upgraded to provide more consistent and reliable oiling to the blade, extending blade life and reducing friction. Proper lubrication is essential for blade longevity. The improved system should help prevent premature blade failure.
- Optional Debarker: A debarker attachment is now available, which removes the bark from the log before it enters the blade, extending blade life and improving lumber quality. Debarkers are a worthwhile investment if you’re milling a lot of dirty logs. They can significantly reduce blade wear and tear.
- Remote Start/Stop: Some models now offer a remote start/stop feature, which allows you to control the engine from a distance. This is a nice convenience, especially when you’re working alone.
Startup Tips: Getting Your LT15 Ready for Action
Setting up your LT15 correctly is crucial for ensuring accurate cuts and preventing damage to the mill. Here are some essential startup tips:
- Choose a Level Location: The mill needs to be perfectly level for accurate cutting. Use a level and shims to adjust the bed until it’s perfectly flat. I cannot stress this enough. An unlevel bed will lead to warped lumber and a lot of frustration.
- Assemble the Mill Carefully: Follow the manufacturer’s instructions carefully when assembling the mill. Make sure all bolts are tightened to the correct torque specifications. I once skipped a step in the assembly process and ended up with a wobbly mill. Don’t make the same mistake I did.
- Install the Blade Correctly: The blade needs to be installed with the correct tooth direction and tension. Refer to the manufacturer’s instructions for proper blade installation. An incorrectly installed blade will not cut properly and can even break.
- Adjust the Blade Guides: The blade guides need to be properly adjusted to support the blade and prevent it from wandering. The blade guides should be close to the blade but not touching it. A gap of about 0.002-0.004 inches is ideal.
- Lubricate the Blade: Use a high-quality blade lubricant to keep the blade cool and prevent it from binding in the wood. I prefer a water-based lubricant, as it’s less messy and easier to clean up.
- Check the Engine Oil and Fuel: Make sure the engine has the correct amount of oil and fuel before starting it. I always use premium fuel in my LT15 to ensure optimal performance.
- Start the Engine and Let it Warm Up: Allow the engine to warm up for a few minutes before starting to cut. This will help to ensure that the engine is properly lubricated and that the blade is running smoothly.
- Make a Test Cut: Before milling a valuable log, make a test cut to ensure that the mill is cutting accurately. A test cut will reveal any issues with the blade alignment, blade tension, or blade guides.
Pro Insights: Maximizing Your LT15’s Performance
Once you’ve mastered the basics, you can start to explore ways to maximize your LT15’s performance. Here are some pro insights that I’ve learned over the years:
- Blade Selection is Key: Choosing the right blade for the wood you’re milling is crucial for achieving optimal performance. Hardwoods require a different blade than softwoods. I keep a variety of blades on hand to suit different wood types. I’ve found that a 4-degree hook angle blade works well for hardwoods, while a 7-degree hook angle blade is better for softwoods.
- Maintain Sharp Blades: A sharp blade is essential for efficient and accurate cutting. Sharpen your blades regularly or send them out to a professional sharpening service. I sharpen my blades every few hours of use. A dull blade will not only cut poorly but will also put unnecessary strain on the mill.
- Adjust Feed Rate: The feed rate (the speed at which you push the saw head through the log) needs to be adjusted based on the wood type and blade sharpness. A slower feed rate is necessary for hardwoods, while a faster feed rate can be used for softwoods. If the blade starts to bog down, slow down the feed rate.
- Use Proper Clamping Techniques: Secure the log firmly to the bed to prevent it from moving during cutting. Use log clamps and wedges to hold the log in place. I’ve seen logs shift during cutting, which can be dangerous and result in inaccurate lumber.
- Consider a Log Turner: A log turner can make it easier to rotate logs on the bed, especially for larger logs. Log turners can save a lot of time and effort, especially when you’re working alone.
- Add Bed Extensions: Bed extensions can be added to accommodate longer logs. Bed extensions are a must-have if you plan on milling logs longer than 20 feet.
- Build a Simple Log Deck: A simple log deck can make it easier to load logs onto the mill. A log deck can be as simple as a few timbers laid on the ground. It will save your back and make the milling process more efficient.
- Consider a Cant Hook: A cant hook is an invaluable tool for moving and positioning logs. I use my cant hook constantly when milling logs. It’s a lifesaver for moving heavy logs.
- Invest in a Moisture Meter: A moisture meter is essential for determining the moisture content of the wood. Proper moisture content is crucial for preventing warping and cracking in lumber. I aim for a moisture content of 12-15% for most projects.
Safety First: Prioritizing Safety When Milling Lumber
Operating a sawmill can be dangerous if proper safety precautions are not followed. Here are some essential safety tips:
- Wear Safety Glasses: Always wear safety glasses to protect your eyes from flying debris. Eye protection is non-negotiable when operating a sawmill.
