Milling in the Winter: Pros and Cons

At the end of the fall season, many sawyers will tuck their sawmills into their sheds for the winter only to uncover them in the spring. The cold air, frozen ground, and snow-covered logs all bring their own set of challenges - and perks! What you may not know is that there are many advantages to milling in the cold, some preferring a cold day of milling to the extreme summer heat. With the right expectations and a few key adjustments, milling frozen logs can be smoother, cleaner, and surprisingly efficient.

Pros of Winter Milling

Cleaner logs:

Skidding logs over snow instead of dragging them through the bare ground means you’re avoiding mud, dirt, and sand - the things that can turn a sharp blade dull in minutes. Snow acts as a natural buffer and keeps the logs much cleaner from the moment they hit the forest floor.

Less Pitch Build-Up:

If you are regularly milling softwoods like pine, spruce, or fir, winter is your best friend. These species are notorious for their sticky resin which can gum up blades quickly in warm weather. When logs are frozen, the pitch is far less active, reducing the amount of buildup on your blades. This not only results in smoother cuts, but also fewer interruptions for blade cleaning.

Reduced Need for Lubrication:

On that note, you need far less lubrication on your blades if you are milling frozen logs. You’ll still want some flow for cleaning and cooling, so replacing the water in your lubrication tank with something with a lower freezing point is good practice. Many sawyers have found a winter-grade windshield washer fluid works well in cold weather.

Things to Keep in Mind

Log Handling Safety:

Even if the snow keeps dirt off your wood, ice itself can wear down a blade, as well. Keeping a stiff brush or axe handy to knock off excess ice before loading a log can be helpful. This can also come in hand to periodically brush excess sawdust off the mill before it freezes in place.

Log Handling Safety:

With snow and ice comes slippery conditions, so be sure to use caution when loading logs, using cant hooks, and watch your footing around the mill itself. Some sawyers suggest laying down traction mats or spreading gravel around the mill to avoid slipping. Take your time with lifting and positioning logs.

Final Thoughts

With the right approach, your portable sawmill can run beautifully all winter long, giving you consistent, clean cuts without mud, mess, and heat of summer. Not mention the beautiful snow-covered view from the mill, a pear all on its own.
