The cabinet design consists of four pieces of solid walnut, connected through rebait joins in the corners, the back of the cabinet will be made from a piece of 3mm hardwood ply covered in walnut veneer (on both sides) to reduce the overall cost of the item. This piece of ply will slot into the groove, routed into the back of the four pieces of walnut, the same way the base board of the drawers will.

The veneer is a very thin layer of walnut and paper backed, PVA glue is applied in a very very thin even layer to the paper side, and similarly the glue is applied to the 3mm ply, and the two layers are pressed together, glue sides together, and smoothed to  remove any air bubbles or pockets of glue trapped between the layers.

The first time I attempted this process, I applied one side of the veneer and stuck it in place with  masking tape to reduce movements/ sliding in the glue, sandwiched it between two thick heavy boards left on the floor and weighted down  with sand bags and cement blocks.  This , was affective to an extent , however this method allowed for some air bubbles to remain   under the veneer as the pressure wasn’t constant enough.

To apply the other side of the veneer, i cut up the boards into the sizes of the drawer base and applied the veneer with a 2.5cm tolerance around size of the board and glued them together, but clamped them using smaller boards  with strip of wood across them to disperse the weight, and g-clamps  and vices to produce a more concentrated force on the plywood veneer. This method produced better results for the drawer bases, but wasn’t as applicable for the larger back piece of the cabinet, due to the size ratio of the vice which was more suited to that of the single drawer bases.

Therefore for the back piece of veneered ply, a hybrid of these two methods was used, the ply was cut to size and i applied veneer to both sides in one go, stabilising it with masking tape to reduce the movement whilst the glue set.  The veneered piece was placed between two heavy boards on a table and weighted down with cement breeze blocks, and the two boards clamped together with g-clamps placed evenly around the boards, again to spread and distribute the weight evenly in attempt to reduce the appearance of air bubble and glue pockets, that would affect the thickness of the veneer surface.
