a) Define the term ’veneering’.
b) Describe the surface hand preparation generally given to the base or core prior to applying the veneer.
a) Define the term ’veneering’.
Veneers are 'peeled' or cut from a timber log or flitch. The way the veneer is cut will effect the grain displayed on the face.
The example below outlines one the methods of cutting veneers and then further below the method of matching these veneers when gluing then to the substrate.
Crown cut
The log is cut in half and the half log or flitch is then sliced straight across, parallel to a line through the centre of the log and tangential to the growth rings. This generally produces a veneer with a central area of strong figurative grain and a more linear effect al each edge.
Book match
Any of the veneers above, except perhaps Rotary cut, can be book matched. Take a pair of veneers face to face are opened like a book and laid onto the substrate.
b) Describe the surface hand preparation generally given to the base or core prior to applying the veneer.
The substrate for the veneer needs to be 'dry', 'flat', and 'smooth'. A surface key is required to allow the adhesive to hold, this key can be provided by hand sanding across the grain with medium to course sandpaper. Some timbers need to be 'sized' that is treated in some way to prevent the natural oils and resins from affecting the glue and weakening the bond.
