A: Strictly speaking, quartersawn lumber isn’t a product of anything you can do to lumber you’ve already bought. It’s a way of sawing boards from a log that orients growth rings perpendicular to the face of the lumber. This is also called “vertical grain” lumber. You’ll find that different boards in a pile are closer than others to the quartersawn lumber ideal, and by careful selection you can choose these for use in crucial areas like bench tops.
What’s So Good About Quartersawn Lumber
So what’s the big deal with quartersawn wood? It expands and contracts less for a given change in moisture than wood with growth rings parallel to the face, and quartersawn wood is much less likely to develop a cup shape than flatsawn lumber. You’ll find that wider boards, such as 2x10s and 2x12s, almost always have quartersawn sections along their outer edges because they’re generally cut from the middle of the log. Narrower boards may or may not have this feature.
If you’re building a bench top you’ve got a couple of options. If it’s a rough bench made with 2x6s, then there’s no need to worry about growth rings and quartersawn wood. Any collection of 2x6s will work fine. If you’re making a more refined bench, you can cut narrower strips of wood from wider boards, rotate the strips as necessary to get the grain pattern correct, then glue them together on their edges. The image here shows a section of board with vertical grain orientation.
As it turns out, there’s a whole world of great, inexpensive wood that’s suitable for fine woodworking. It’s available for in the form of wide planks of framing lumber destined for floor joists and house frames. Sounds too good to be true, but it’s actually a great opportunity.
