Milling Lumber on the Farm

Which logs are worth milling?

Straight, sound logs of a species suited to the job give the best return. Check each log for rot, large knots, heavy sweep, cracks and signs of metal such as old fence wire or nails, which can ruin a blade. A log that looks sound outside can hide a rotten center, so cut a small sample and look at the face before you commit to milling the whole log. Wet, muddy logs should be rinsed or scraped, because grit dulls blades in minutes.

Some species suit outdoor use and others make better indoor stock. Ask a local sawyer or extension forester which of your species are best for your project.

Cut logs fresh when possible. Logs left lying on the ground for long periods can stain, crack or be attacked by insects, and the lumber loses value.

How should I plan the cuts?

Plan the product before the first cut. Decide what sizes you need, what grades you will accept and what will become firewood or mulch. A rough plan keeps you from cutting boards you cannot use.

Many sawyers turn the log to cut around the best face, so the clearest boards come from the outside. Cutting methods change how boards behave as they dry, which a sawyer can explain in person.

Keep thickness consistent, and allow extra for drying and planing if you will finish the boards later. Measure twice and write down each size cut.

How do I handle and stack boards?

Fresh boards are heavy and wet. Stack them as they come off the mill, with spacers between layers so air can move freely, and on a flat, solid base off the ground.

Cover the stack from rain and direct sun, but keep the sides open for airflow. Bad stacking leads to warped, stained and moldy boards.

Label stacks with species and date. A year from now you will not remember which pile is which.

• Flat, firm base that keeps boards off the soil
• Evenly spaced spacers lined up vertically
• Weight on top to reduce warping
• Roof or cover with open sides

What are the safety and health concerns?

Heavy logs and blades are the main dangers. Lift with equipment or with helpers, and never reach near moving blades. Wear hearing and eye protection and a dust mask for fine sawdust. Keep your hands clear of the blade, use push tools instead of fingers, and make a habit of stopping the engine before you clear sawdust or adjust anything.

Some wood dust irritates the lungs or skin, and some species are worse than others. Ask a doctor or your county health office if you have breathing problems.

Keep people and pets away from the mill, and keep a first aid kit and phone nearby.

What can go wrong with quality?

Common problems include uneven thickness, wavy boards from a dull blade, and warping from poor drying. Beginners also tend to saw too fast, which makes rough surfaces. Sharp blades, steady feed rates and well-supported logs are the three habits that produce smooth, flat boards more than any other factors.

Mistakes are part of learning. Save the oddballs for projects where appearance does not matter, such as stalls, sheds and temporary structures.

Keep notes on what you cut and the results. Tracking blade changes and cutting speed helps you improve.

• Dull blade or feeding too fast
• Log not clamped or supported well
• Uneven stacking or poor drying
• Cutting without a plan for each board

Do I need permits or approvals?

Using lumber for your own buildings may still involve building rules. Counties and towns often have permit requirements and standards for structural lumber. Ask your county building or zoning office what is required.

If you plan to sell lumber, check local business rules and how lumber must be graded or labeled for sale. Rules vary by state and county.

For structural uses, ask an engineer or building official before relying on lumber you cut yourself. This is not professional advice.

What does it really cost?

Costs include the mill or the hire of a sawyer, blades, fuel, time, equipment and drying space. Compare the total against buying the lumber you need. Ask local woodworkers whether they would buy rough lumber from you, and what species and sizes they want. A ready buyer for even part of the output changes the math.

For many families the value is in using material that would otherwise be wasted, and in the satisfaction of building with their own trees. That is reasonable, as long as the numbers are honest.

Start small, learn the process on a few logs and decide later if you want to scale up.
