Resawing thick walnut into bookmatched panels asks more of a band saw than ordinary curve cutting. The saw must hold a wide blade steady through a deep cut, keep the blade tracking under load, and leave stock that can be flattened without wasting much thickness. Capacity matters, but a tall frame alone does not guarantee a clean result: blade choice, setup, and feed rate matter just as much.

What to buy for resawing
For occasional panels from boards up to about 6 inches thick, a well-set-up 14-inch band saw with a riser block can be adequate. It is the budget route, but the narrower frame, smaller wheels, and limited motor power leave less room for error. Expect to resaw slowly and allow extra thickness for cleanup.
For regular work in 8- to 12-inch stock, look at a 17- or 18-inch saw with roughly 1½ to 2 horsepower, a tall fence, and a resaw capacity that exceeds your actual board thickness. A 14-inch machine may list enough capacity after a riser is fitted, but capacity is not the same as comfortable cutting performance. Large wheels and a rigid frame generally support a wide blade better.
If you routinely resaw wide, valuable slabs or work above 12 inches thick, a 19- or 20-inch machine with a stronger motor and a heavy frame is worth considering. These cost more, take up more floor space, and may need a 240-volt circuit. They are not automatically necessary for a few bookmatched panels a year.
Compare 17-inch band saws for resawing and check the manufacturer’s published resaw capacity, motor rating, and required voltage before choosing. Do not rely on a retailer’s headline capacity alone.
Compare saw sizes
| Band saw class | Practical use | Main trade-off |
|---|---|---|
| 14-inch, often with riser | Occasional resawing up to roughly 6 inches | Lower cost, but slower and less forgiving with wide blades |
| 17- or 18-inch | Regular work around 8 to 12 inches | Good balance of capacity and footprint; motor and frame quality vary |
| 19- or 20-inch | Frequent, deep resawing and larger stock | Higher purchase, space, and electrical demands |
These are broad buying ranges, not guarantees. A dull blade, poor tension, or a board with internal stress can make a large saw cut badly. Conversely, a careful operator can get useful panels from a smaller machine if the stock fits and the blade is suited to the task.
Blade and fence matter
For thick walnut, a sharp ¾- to 1-inch resaw blade is a sensible starting point if the saw accepts it and can tension it correctly. A blade with about 2 to 3 teeth per inch clears sawdust from a deep kerf better than a fine-tooth blade. Choose a blade intended for resawing, and check its recommended tension and minimum wheel size. A wide blade that the saw cannot tension properly can wander rather than cut straight.
A tall resaw fence supports the board through the cut. A drift-adjustable fence, or one that can be aligned to the blade’s actual tracking, is useful because blades do not always cut parallel to their backs. For bookmatching, a small deviation can leave one panel thicker at one edge and reduce the material available for flattening. A point fence can also work, but it takes more practice to keep the board steady.
Shop for a wide resaw blade only after checking your saw’s blade-length range and maximum blade width. Do not assume the widest blade listed as compatible is the best choice for every cut.
Prepare the walnut before cutting
Start with dry, straight stock. A bowed or twisted board can bind against the fence, pinch the blade, or come apart unpredictably as internal stress is released. Joint one face and one edge if possible, then mark the intended bookmatch sequence and keep the pieces in order. If the board is too rough to sit securely, establish a stable reference face before resawing.
Use a sharp blade, set tension according to the saw and blade maker, and verify that the blade tracks correctly on the wheels. Check that the fence is aligned to the blade’s cut, not merely to the table slot. Make a test cut in scrap of similar thickness. If the blade bows away from the fence, reduce feed pressure, check sharpness and tension, and confirm the fence setup before risking the walnut.
Feed steadily without forcing the stock. Excessive pressure can deflect the blade; too slow a feed can also rub and heat the blade. Listen for a change in motor sound and watch whether the cut begins to drift. Keep hands clear of the blade path, use push aids when needed, and never reach behind a moving blade to catch a falling offcut.
Plan for cleanup and bookmatching
Set the cut thickness to leave material for flattening both faces. A practical allowance is often around ⅛ inch total, but warped stock or a rough cut may need more. For example, splitting a 2-inch board into two panels near ⅞ inch each leaves about ¼ inch combined for kerf and cleanup; the exact yield depends on kerf width and how flat the original board is. Measure the actual board rather than relying on nominal lumber dimensions.
After the cut, keep the two faces in sequence and open them like a book to check the figure. If the panels are still under stress, let them rest before planing. A planer can remove saw marks, but it will not safely flatten a panel that rocks or has severe twist; flatten one face first with a sled, router setup, or other suitable method. A jointer is not the right tool for a wide, unstable panel.
When a cheaper saw is enough
A 14-inch saw is a reasonable choice when your walnut is modest in thickness, resawing is occasional, and you can accept a slower cut plus extra planing. Buy the best blade and setup you can manage before upgrading the machine. If you regularly cut thick, high-value boards, though, the time spent coaxing a small saw—and the risk of losing usable thickness to drift—can outweigh its lower purchase price.
For frequent deep cuts, prioritize a rigid frame, adequate motor, reliable blade tensioning, and a fence that stays square under pressure. Capacity should be comfortably greater than your thickest stock, not exactly equal to it. That margin makes setup easier and leaves room to work safely.
