Milling your own lumber is one of the most satisfying skills a woodworker or homesteader can learn. Instead of paying premium prices at the lumberyard, you can take a log that would otherwise be firewood and turn it into slabs, boards, and beams for a fraction of the cost. This guide covers everything a beginner needs: whether it’s worth it, what equipment to choose, how to cut a log into boards, and how to dry that lumber so it doesn’t crack or warp.
Is Milling Your Own Lumber Worth It?
For most people, yes — but it depends on your goals. If you have access to logs (your own land, tree services, storm damage, or free listings), milling turns raw material into lumber worth many times the cost of cutting it. A single walnut or oak log can yield hundreds of dollars in boards or a one-of-a-kind live-edge slab you can’t buy off a shelf.
The trade-off is time and labor. Milling is physical work, and drying takes months. It makes the most sense if you have a supply of logs, want unique wood, and enjoy the process.
The Two Main Methods: Chainsaw Mill vs Bandsaw Mill
Nearly all home milling is done one of two ways, and choosing between them is the biggest decision you’ll make.
| Chainsaw mill | Bandsaw mill | |
|---|---|---|
| Startup cost | Low | High |
| Cutting speed | Slow | Fast |
| Kerf (wood wasted) | Thick (~3/8″) | Thin (~1/16″–1/8″) |
| Portability | Excellent | Limited |
| Best for | Hobby, slabs, occasional use | Volume, regular milling |
The chainsaw mill
A chainsaw mill (Alaskan mill) clamps onto your chainsaw’s bar and slides along a log at a set thickness. It’s cheap, portable, and perfect for wide slabs cut where the tree fell. The downsides are speed and waste: it’s slow, tiring, and its thick kerf turns a lot of wood into sawdust. It also demands a powerful saw.
The bandsaw mill
A bandsaw mill uses a thin band blade on a carriage that rolls down the log. It cuts several times faster, wastes far less wood, and produces flat, even boards with less effort. The catch is cost and portability — they start in the thousands, and the log has to come to the mill.
Which should a beginner buy? Most people start with a chainsaw mill to learn cheaply, then move to a bandsaw mill once they’re milling enough to justify it.
Choosing the Right Logs and Wood Species
Great lumber starts with a good log: straight, with a large clear section, and as few knots as possible. A slight taper is fine; a log that spirals or bends sharply gives cupped, twisted boards. Fresher logs cut cleaner and are less likely to hide rot or cracking.
- Oak — hard and strong; great for furniture, flooring, beams. Dries slowly.
- Walnut — premium furniture wood, high value even in small amounts.
- Maple — hard and pale; figured maple is especially valuable.
- Cherry — smooth and warm-toned, a fine-furniture favorite.
- Pine and softwoods — fast and easy to mill, great for practice.
Watch for metal: yard and fence-line trees often hide nails or wire that can destroy a chain instantly. Inspect the log first.
The Gear You Actually Need
A powerful chainsaw
Milling cuts along the grain, which is hard on a saw. For logs up to ~18″, use at least a 60cc saw; for wider logs, 70–90cc or more. Underpowered saws overheat and bog down.
A ripping chain
A ripping chain has a shallower angle designed for cutting along the grain — smoother and faster than a crosscut chain. This cheap upgrade makes a big difference.
The mill attachment, guide rail, and safety gear
Get an Alaskan-style mill sized for your bar, plus a straight guide rail (or rigid ladder) for the first cut. Wear chaps, a helmet with face shield, hearing protection, and gloves, and keep plenty of bar oil on hand.
Keeping Your Chainsaw Milling-Ready
Milling is the hardest work a saw ever does. Keep the chain sharp (touch it up every 1–2 hours and stop if you hit dirt or metal), keep the chain properly tensioned and well oiled, and clean out the air filter and bar groove after each session. Ten minutes of cleanup adds years to the saw.
How to Mill a Log, Step by Step
- Choose and prep the log. Pick a straight, sound log. Clean off dirt and grit, support it off the ground, and wedge it so it can’t roll.
- Set up the first cut. Fix a straight guide rail to the top of the log to create a flat reference face. Take your time getting it level.
- Make the first slabbing cut. Start at full throttle and ease the mill in. Let the saw pull itself through; forcing it only bogs the engine. Keep the oil flowing.
- Cut boards to thickness. Remove the rail; the flat face is now your reference. Set thickness (about 1″ for boards, 2–3″ for slabs) and repeat, flipping the fresh flat face onto the rails each pass.
- Cut slightly oversize. Wood shrinks and you’ll plane it later, so cut a little thick — e.g. 1-1/8″ for a finished 3/4″ board.
Pro tip: number your boards in cutting order so you can book-match the grain later for stunning tabletops.
Flattening and Finishing Your Boards
Milled boards rarely come off the log perfectly flat. Once dry, boards that fit a thickness planer are easy; wide slabs won’t fit, so most home millers build a router sled — a flat frame a router rides across to skim both faces flat at any width. After flattening, sand up through 80, 120, then 180 grit and finish with oil, wax, or polyurethane. Live-edge slabs get the bark removed and cracks stabilized with epoxy first.
Let it acclimate: let boards sit indoors for a week or two before final flattening, since wood keeps moving until it reaches the humidity of its final home.
Drying and Storing Your Lumber
Fresh-cut lumber is full of water and will crack and cup if dried wrong. Proper drying is what separates usable boards from firewood.
Sticker, stack, and seal
Stack boards flat with thin spacers (stickers) of equal thickness between every layer, lined up vertically, and put weight on top. Keep the stack out of direct sun and rain but with good airflow. Coat the cut ends with a wax sealer, paint, or glue right after milling to prevent end-checking.
How long it takes
The classic rule for air drying is roughly one year per inch of thickness. A 1″ board takes about a year; a 2″ slab, about two.
Air drying vs kiln drying
Air drying is free and simple but only reaches outdoor humidity (~12–18% moisture) — fine for outdoor and rough work. Kiln drying reaches 6–8% in weeks and kills insects, but needs a kiln or a service. Many millers air-dry most of the way, then finish indoors before building. For most projects, patient air drying is all you need.
What It Costs to Get Started
| Setup | Rough startup cost |
|---|---|
| Chainsaw mill attachment + ripping chain | $200–$400 |
| A capable used chainsaw (if needed) | $400–$900 |
| Entry-level manual bandsaw mill | $2,000–$4,000+ |
Prices are rough ranges — check current pricing in your area. A chainsaw-milling setup can pay for itself with a single decent log.
Turning Milled Lumber Into Money
Once you’re comfortable milling, the same skill can pay for your equipment. Wide, character-rich live-edge slabs for tables and countertops are the highest-value product a small mill makes. You can also cut custom orders for woodworkers who need specific species or dimensions, and sell dimensional lumber, mantels, bench blanks, and turning stock. Price standard lumber by the board foot and character pieces per slab; dried, flattened wood commands far more than green, rough-cut boards.
Common Beginner Mistakes
- Using a crosscut chain instead of a ripping chain.
- Under-powering the saw for the log width.
- Skipping stickers, so boards warp as they dry.
- Not sealing the ends, causing cracks.
- Rushing the drying and building with wet wood.
Staying Safe
Milling pushes both the saw and the operator hard. Always wear protective gear, keep both hands on the saw, and stand to the side of the bar — never in line with it. Take breaks before fatigue sets in, and don’t mill alone if you can avoid it.
Frequently Asked Questions
What size chainsaw do I need to mill lumber?
For logs up to about 18″, a 60cc saw is a reasonable minimum. For wider logs, choose 70–90cc or larger for enough torque.
Do you really need a special chain?
Yes — a ripping chain cuts along the grain far smoother and faster than a crosscut chain.
How long does milled lumber take to dry?
Air drying takes roughly one year per inch of thickness. A kiln does it in weeks.
How do you flatten a slab that’s too wide for a planer?
Build a router sled that skims the slab flat on both faces — it handles any width for a fraction of the cost of a wide planer.
How much can you make selling milled lumber?
It varies, but a single character slab can bring hundreds of dollars, and custom milling adds up quickly.
