Exploring the Cutting Capacity of a Granberg Alaskan® Chainsaw Mill: How Large of a Log Can It Handle?

The Granberg Alaskan® Chainsaw Mill has revolutionized lumber milling by making it accessible to woodworkers, builders, and outdoor enthusiasts. Its portable design and impressive flexibility allow users to transform raw logs into usable lumber on-site. But just how large of a log can this mill handle? Here’s a detailed look at its cutting capacity, features, and why it’s the go-to choice for both professionals and hobbyists.

Understanding the Granberg Alaskan® Chainsaw Mill

The Alaskan Chainsaw Mill is a portable sawmill that attaches directly to your chainsaw bar. It’s perfect for turning logs into slabs, beams, and planks, making it a versatile tool for construction, furniture making, and woodworking. With precision engineering and user-friendly features, the Granberg Alaskan® MKIV Chainsaw Mill delivers professional-grade results without the need for heavy equipment.

What Determines Cutting Capacity?

1. Mill Size

Granberg offers several Alaskan Mill models to accommodate different chainsaw bar sizes. Each mill has a maximum cutting width determined by its size:

  • 24-inch Mill: Cuts logs up to 18 inches wide.
  • 36-inch Mill: Cuts logs up to 30 inches wide.
  • 48-inch Mill: Cuts logs up to 42 inches wide.
  • 84-inch Mill: Cuts logs up to 78 inches wide.

2. Chainsaw Bar Length

While the mill size sets the framework, your chainsaw bar length determines the actual cutting width. A portion of the bar is used to mount the mill, so the effective cutting width is typically 6 inches shorter than the bar length.

3. Log Diameter

To determine the largest log your mill can handle, add a few inches to the effective cutting width. For example:

  • A 36-inch mill with a 36-inch bar can handle logs up to 30 inches in diameter.

Granberg Alaskan® MKIV: Built for Large Logs

The MKIV Chainsaw Mill is designed for precision and durability, making it an excellent choice for milling large logs. Here’s why it stands out:

Sturdy Construction

Made from aircraft-grade aluminum and zinc-plated steel, the MKIV is lightweight yet strong enough to handle oversized logs without compromising stability or performance.

Customizable Setup

Available in multiple sizes, the MKIV accommodates a wide range of chainsaw bar lengths, from 24 inches to 84 inches.

Optimized Ripping Chains

Pairing your mill with Granberg Ripping Chains ensures smoother cuts and less strain on your chainsaw, even when working with dense hardwoods like oak or walnut.

Advantages of the Alaskan Chainsaw Mill

1. Portability

Unlike stationary sawmills, the Alaskan Mill is lightweight and portable. You can mill logs directly at the site, eliminating the need for transporting heavy timber.

2. Cost-Effectiveness

The Alaskan Mill is a budget-friendly alternative to large sawmills, making it ideal for DIYers and small-scale woodworkers.

3. Versatility

From small slabs to massive planks, the Alaskan Mill can handle a variety of log sizes and wood types, including both hardwoods and softwoods.

4. Precision

The MKIV model features CNC-machined billet end brackets for improved accuracy. When paired with the EZ Rail System, users achieve perfectly level and consistent cuts.

Tips for Milling Large Logs

  1. Choose the Right Chainsaw For logs over 30 inches in diameter, use a high-displacement chainsaw (90cc or more) for efficient cutting. Options like the Stihl MS 661 or Husqvarna 395XP are ideal.
  2. Use Ripping Chains Always use specialized Granberg ripping chains for smoother cuts and reduced strain on your chainsaw.
  3. Add an Auxiliary Oiler This is a necessity when using a double ended bar with a helper handle. For extended single-end bars, an auxiliary oiler ensures proper lubrication, preventing overheating and extending the life of your chain.
  4. Secure the Log Use chocks, wedges or some kind of cradle for the log.
  5. Maintain the Chain Regularly sharpen your chain using Granberg’s Precision Grinder for optimal performance.
  6. Pace Yourself Milling large logs takes time. Maintain a steady feed rate to avoid overloading your chainsaw and mill. An Alaskan winch will assist in this.
  7. When milling logs over 48″ in diameter Use the 24″ extended crossbars with your EZ rails
