Let me just say this about that! The winch attachment to the Alaskan chainsaw mill works great; I don’t know how I have managed without it. It eliminates much of the strenuous physical labor otherwise required. The quality of the cuts is improved, as is productivity.

Lessons Learned – Alaskan Chainsaw Mill and Winch
Fifty ft of rope is probably more than needed 99% of the time, that is enough for a log close to 25 feet long; we took about 16 feet off during the test to make more room on the winch spool.
The rope is either routed over or under the handle of the Granberg, in the run between the pulley and the winch; under the handle seemed to work best, but this may be an opportunity for incremental improvement.
Nails are sufficient for anchoring the pulley to the end of the log.
The first 6 inches into the log, and the last 12 inches or so, are cut without the aid of the winch.
Keep the attachment points for the winch, and carabiner at the end of the rope, as low as possible on the Granberg MkIII Chainsaw Milling Attachment; “racking” the mill, which is to say, tipping the mill towards the far end of the log, can occur, causing the chain to cut deeper into the log. In deeper cuts, where the “thickness rails” are far above the bar, pay particularly close attention to this possibility.
As the log narrows, and/or as mill closes on the pulley, the carabiner attachment point will likely need to be moved towards the center of the log, to maintain roughly equal tension on the ends of the bar nearest and furthest from the powerhead.
When Alaskan chainsaw milling, bring plenty of gas/oil mix, and plenty of bar and chain oil; in a 30 inch diamter, 8 foot log, both tanks on the powerhead were close to empty at the end of each cut.
And this is a lesson you do not want to learn the hard way; wear appropriate safety gear, including hearing and eye protection, gloves, and chainsaw chaps.
