Granberg G777 Alaskan Small Log Mill, 16 to 20 Inch Chainsaw Bar

The Granberg G777 Alaskan Small Log Mill turns a standard chainsaw into a portable lumber maker. Built for outdoor DIY projects, it lets you process logs directly where the tree falls instead of hauling heavy timber elsewhere. It is aimed at beginners and hobbyists who want to create their own boards without investing in industrial milling machinery.

Setup is straightforward because the attachment clamps directly onto your existing chainsaw bar. You do not need to drill holes into your equipment, keeping your chainsaw intact. The package includes all the required assembly hardware and an instruction manual, making it accessible even if you have never milled lumber before.

A key limitation is chainsaw bar compatibility. This specific model is sized exclusively for 16 to 20-inch bars, and the manufacturer specifies that you must use a solid steel bar. It will not accommodate larger guide bars or alternative bar constructions not rated for clamping.

Verdict: The Granberg G777 is an accessible, practical choice for landowners and woodworkers wanting to mill small logs on site. If you have a chainsaw with a 16 to 20-inch solid steel bar, it delivers straightforward lumber cutting without complicated modifications.

A great fit if you:

• Want to mill small logs right where trees fall on your property
• Own a chainsaw equipped with a 16 to 20-inch solid steel bar
• Prefer a clamp-on design that does not require drilling your bar
• Are new to DIY milling and want an entry-level attachment

Consider something else if you:

• Need to mill large logs requiring guide bars over 20 inches
• Use a chainsaw bar that is not made of solid steel
