Veneers used to be cut by the hand-saw; at present, the circular saw is, I believe, universally employed in England for this purpose, with the advantage, not only of cheapness and expedition, but of a smaller waste of wood in sawdust, and for greater accuracy and precision in the thickness of the veneer — a quality essentially requisite to produce good work in the finished article.
In a large veneer-mill which I had an opportunity, through the kindness of one of our members, of visiting, there are five circular saws. Each consists of a strong, stiff, circular frame-work, of the shape of a plano-convex lens, or rather a low hollow cone, tapering gradually to the edge, from which projects a ring of soft steel a few inches broad, pierced with many holes. The saw is a plate, or rather a flat ring, of well-tempered steel, about twelve inches broad, pierced with as many holes as the former ring, and firmly secured to it by means of screws: a band over the axis of the saw communicates motion to it, by connecting it with the first mover, which is a steam engine.
