It usually varie s in thickness from one-hundredth inch to one-eighth inch, though it is commercially possible to cut it thinner, and thicker sizes are to be obtained. However, in general, veneer used in aircraft falls withi n the limits stated ; There are three common methods of manufacturing veneer, a s follows : (1) The rotary process, (2) the slicing process, (3) the sawin g process . By far the greater portion of all veneer manufactured is mad e by the rotary process . Veneer made by this process is all slash cut , and the length along the grain is limited by the length of the venee r lathe . Rotary veneer longer than 100 inches is more or less uncommon. Sliced veneer is usually manufactured only from the finer woods . On account of the fact that it is possible to rroduce quartered venee r on slicing machines, and the waste on account of saw kerf is absent , this method of manufacture is preferred where pattern is important an d the value of the wood is great . The length parallel to the grain o f sliced veneer is limited by the length of the knife . ;awed veneer can be uroduce', in almost am reasonable length and from any kind of stock . The material produced may he Other quart- ered or slash . In general, sawed veneer will not be soeci .f'iet for air- craft uses, to the excli'o ion of rota= stock, exceut where it i s necessary to have extra. long lengths or quartered. stock or for some other reason it is impossible to secure the stock by rota= chtting . It may happen, for instance, that the stock from which the veneer is t o be cut can not he handle r, to advantage in a rotary lathe on account o f its shape . A sp
