The Original Alaskan® Chainsaw Mill
Granberg invented the portable chainsaw mill in 1965. The MKIV is still the most reliable way to turn any fallen tree into dimensional lumber — right where it stands, with the chainsaw you already own.
Granberg Alaskan MKIV — Everything Included
Nine bar lengths from 36″ to 84″. One precision-machined aluminum frame that clips to any chainsaw and turns any log into dimensional lumber — right where it fell. Every component included. American-made since 1965.

Tips for First Time Users
Four Steps from Tree to Timber
Step 01
Attach to Bar
Clamp the MKIV frame to your chainsaw bar and tighten. No tools needed beyond what's included.
Step 02
Set Your Guide
For the first cut, attach a level board to the log. The EZ Rail system makes this effortless.
Step 03
Adjust Depth
Set the depth posts to your desired slab or board thickness — 1″ to 12″ or more.
Step 04
Mill Your Lumber
Move at a steady pace and let the ripping chain do the work. Dimensional lumber, live-edge slabs, beams — unlimited dimensions.
