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

The Granberg G777 Alaskan Small Log Mill is a portable chainsaw attachment designed to mill lumber right where a tree falls. It provides an accessible solution for landowners and DIY woodworkers who want to process smaller logs without transporting them to a commercial sawmill. Because it requires no previous milling experience, anyone with a compatible chainsaw can start producing their own rough-cut lumber.

Setup is straightforward thanks to the clamp-on mounting system. The mill attaches directly to your existing chainsaw bar, which means you do not have to drill any holes into your equipment. Granberg includes both the assembly hardware and an instruction manual in the package, helping you put the attachment together and secure it to your saw properly.

This tool does come with specific hardware limitations. It is designed for chainsaw bars between 16 and 20 inches in length, and it strictly requires a solid steel chainsaw bar to operate safely. It will not work with bars outside this size range or with non-solid bar constructions.

Verdict: The Granberg G777 is an excellent choice for DIYers and woodworkers who own a compatible 16 to 20-inch solid steel chainsaw bar. If you want a straightforward attachment that turns fallen trees into usable wood on the spot, this mill delivers the necessary functionality without complex modifications.

A great fit if you:

• Want to mill logs directly where the tree falls
• Have a chainsaw with a 16 to 20-inch solid steel bar
• Are new to milling and want an accessible DIY setup
• Prefer a clamp-on design that does not require drilling into your bar

Consider something else if you:

• Use a chainsaw bar smaller than 16 inches or larger than 20 inches
• Do not have a solid steel chainsaw bar
