Short answer: cut first, flatten second
A band saw and a jointer solve different problems when stock has curves, crooks, or uneven edges. Use the band saw to remove material along a curved or irregular line. Use the jointer afterward only if you need to create a flat face or a straight, square edge—and only when the piece has a stable, safe reference surface.
A jointer is not a substitute for a band saw. Its cutter head and tables are designed to flatten a face or straighten an edge, not to follow a curve. Trying to joint a narrow, wavy, or rocking piece can produce a poor cut or a dangerous kickback. For many one-off curved projects, a band saw and hand tools are enough; buying both machines makes sense only if you regularly need both operations.

What each machine does
A band saw feeds stock past a continuous blade running around two wheels. The blade can follow a curve, and the saw can resaw thicker stock with an appropriate blade, capacity, and setup. It leaves a cut surface that usually needs sanding, scraping, or planing.
A jointer uses a rotating cutter head between infeed and outfeed tables. For face jointing, it removes high spots to make one face flat. For edge jointing, it makes an edge straight and square to the jointed face. A typical jointer has limited width capacity, so check the machine’s cut width against your stock; a common benchtop size is 6 inches.
Band saw vs. jointer
| Task or condition | Band saw | Jointer |
|---|---|---|
| Cut a curve or irregular outline | Right tool; choose a blade that can turn the curve | Not suitable for following a curve |
| Remove a crook from an edge | Can rough-cut a straighter edge, leaving cleanup | Can straighten a stable edge with controlled passes |
| Flatten a broad face | Not its job | Yes, within the machine’s capacity |
| Stock that rocks or has no flat reference | Can cut to a layout line if it is supported securely | Risky; stabilize or establish a reference first |
| Finish quality | Rougher surface; often needs cleanup | Can leave a clean, flat surface when set up correctly |
Preparing irregular stock on a band saw
Mark the intended outline and identify which side is waste. Secure the work with both hands clear of the blade path, and support long or awkward stock so it cannot twist or tip as the cut progresses. If the piece has a bark edge, loose knots, or a steep curve, remove loose material first and plan the cut so the blade does not bind. Never force the work through a tight turn; the blade can deflect, wander, or stall.
Blade width matters. A narrower blade can turn tighter curves, while a wider blade is generally easier to keep on a straight resaw cut. The blade’s stated minimum curve radius is a useful starting point, not a guarantee: wood species, blade condition, tension, and feed rate affect tracking. For a finished outline, leave roughly 1/16 to 1/8 inch outside the line for sanding or spokeshaving. That margin is less useful if the blade wanders substantially, so make a test cut in scrap first.
A benchtop woodworking band saw can be adequate for small projects and curves in thinner stock. Check throat depth, resaw capacity, blade availability, and whether the machine can be tensioned properly for the blade sizes you plan to use. The least expensive saw may be fine for occasional contour cuts, but a small throat or weak resaw capacity can become limiting quickly.
When to joint—and when not to
After a rough band-saw cut, jointing is useful only if the remaining surface can sit steadily on the jointer table and the cut you need is straight or flat. For example, once you have sawn a rough edge on a board and established a stable face, light edge-jointing passes can create a straight edge for a table-saw rip. Keep cuts shallow: around 1/32 inch is a sensible starting depth for many hardwood tasks, adjusted to the machine, wood, and cut quality. Recheck the edge between passes rather than trying to remove all the waste at once.
Do not put a curved edge against a jointer fence expecting the machine to preserve the curve. The cutter removes high points, and the result is a changing, often unintended profile. Do not face-joint a board that rocks, bridges over a hollow, or has a loose knot. It may shift into the cutter head or be thrown back. Short, narrow, or tapered pieces also need special care; use appropriate push blocks and follow the machine manual’s minimum workpiece dimensions. If the stock cannot be held securely, use another method.
A jointer is a good purchase if you routinely need flat faces and square edges before planing or milling. A 6-inch woodworking jointer suits many small-shop boards, but its width is a real limit. Wider stock may need a larger machine, a router sled, hand planes, or another flattening method. A planer alone will make the opposite face parallel to the face presented to it; it will not reliably flatten a board that rocks on its bed.
Choose by the stock you actually prepare
If you mostly make signs, templates, furniture parts, or live-edge projects, prioritize a band saw with enough throat and capacity for your largest work. If you buy rough lumber and need dependable flat faces and straight edges, a jointer is more central to your workflow. If you do both, they complement each other: band-saw away excess or cut a profile, then joint only the reference surfaces that genuinely need to be flat or straight.
For occasional work, a cheaper route can be sensible. A band saw can rough out a curved part, with a rasp, spokeshave, hand plane, or sanding block bringing it to the line. For a small amount of board flattening, a hand plane or router sled may cost less than a jointer and take up less floor space. The trade-off is time and skill, not a promise of identical speed.
Before buying either machine, measure your typical stock, not just the largest piece you can imagine. Check cutting capacity, table support, dust collection, blade or cutter availability, and the room needed to feed long boards safely. The right choice is the machine that handles your recurring operation; irregular stock alone does not make a jointer necessary, and a band saw cannot replace a jointer when a genuinely flat reference face is required.
