Explain the meaning of book matched veneers and sketch a method of holding two veneers together prior to gluing.
Methods of Matching Veneers when adhering them to the substrate.
Book match
Any method of slicing veneers, except perhaps Rotary cut, can be book matched. Take a pair of veneers face to face and open them like a book then lay them onto the substrate.
Slip Match
Veneer slices are joined in sequence without flipping the pattern. If the grain is straight, the joints will not be obvious. Successive veneer leaves in a flitch are "slipped" one alongside the other and edge-glued in this manner. The result is a series of grain repeats, but no pairs. The danger with this method is that grain patterns are, rarely, perfectly straight. Where a particular grain pattern "runs off" the edge of the leaf, a series of leaves with this condition could visually make a panel "lean." In book matching, the pairs balance each other.
Reverse Slip Match
In reverse slip matching the veneer leaves are slipped out from under each other and every other veneer leaf is flipped end to end. This balances the character of the veneer in the panel face Normally used with crown cut veneers to balance the crowns so that they do not all appear at one end of the sheet.
Holding Veneers together while gluing
Lay the veneers face up and match them as described above. Use a low tack masking tape over the joints to hold them together before turning over to apply the glue. When the veneers are successfully glued to the substrate remove the masking tape as soon as possible to prevent the masking tape glue from effecting the face of the veneer.
