Book-matching is when you use consecutive boards from the same log to create a repeating pattern in the grain (such as with the knots in the box top above). There are guitars I remember the wood and the sound (if I get to play it), even when it’s been years later after only seeing/playing it for a short time, just because it leaves an impression. SLIP MATCH is a method of matching veneers for the face of plywood where consecutive sheets of veneer are slipped out, side by side and joined together with a repetition of the same grain appearance. It enabled complete control in what was an extremely difficult wood to control. Book Matching – Laying up two or more veneers side by side with opposite faces showing.
The manner in which these are arranged or spliced is called matching and has a dramatic effect on the appearance. The quarter log is mounted on a modified lathe to produce a cut that crosses both the growth rings and the rays at a slight angle, resulting in a relatively straight grain effect that minimizes the bold ray flake appearance found in quarter sliced wood.
All sheet images on this site are as true to colour as possible, but being natural wood, grain and shade variations are inevitable. If the sides are book matched and both sides of the dulcimer are mirror images of each other, these internal pressures are close to being balanced. Since this cut follows the log’s annual growth rings, a bold variegated grain marking is produced. Generally produces a wide heart with reduced quarter grain on the sides of the crown.
Slip Match is achieved when the veneer slices are joined in the same sequence they were removed from the log and without flipping the pattern. Quad Matching – A combination of book matching and butt matching in which four or more veneers are laid up side by side and end to end. Where the height of a flitch does not permit its fabrication into the desired height of panel, it may be matched with vertical butts as well as with horizontal book leaf joins.
To the original questioner: I would guess that the architect doesn’t know the difference, he’s heard book match and that’s all he knows. Bookmatching is a safe way to get the width if the two pieces are from the same center cut and the closest you will get to grain match, moisture level, color, ect. The direction, size, arrangement and appearance of the fibers in wood or veneer.
In this case I needed only one apron to match three other that had consistent grain so I glued a thick piece to the apron and band-sawed off the bulk when dry. With this set of veneers I think I like the book match better (notwithstanding the possible differences in the look after finishing as you rightly pointed out). In a fine-grain, or near grainless lumber-Ash, Poplar, Alder (sometimes), you can get a really hip sort of Danish Modern” grain effect going. Veneer book matching can be used with rift, quarter, or plain sliced wood veneers.
Wood slabs that are fabricated by Boards and Beams and are sold to customers for their installation do not come with warranty for twisting and cupping. This end match has leaves that are book or slip matched in a continuous patter, either vertically or horizontally. Each panel face is assembled from as many veneer leaves as necessary so that the widths and number of matching veneer leaves are not requirements. At this point your iron should be turned up to it’s maximum setting, i.e. 200º c. if using burr wood veneer it is sometimes better to double up on the hot melt film.
The finish makes the surface smoother and transmits light deeper into the wood grain, which reduces surface scattering. I believe the barber pole visual effect of book matching is due to reversed grain direction rather than the method used to produce the veneer. This handy tool allows you to compare the cost and FSC certified availability of some of our most common veneer species.
The remedy of this problem is achieved by progressively book matching lengthwise as well as horizontally, thus achieving a uniform grain progression in both directions. Using an adjustable square to make a line down the center of your board and mark the cut for the book match. If you look really carefully at the grain, you will see that most of the time the halves are indeed book matched.
