Bevelling Wood

It is chiefly in woodwork that beveling is found ; it means the production of surfaces which are neither at right angles nor parallel with each other. A box or tray with splayed or sloping sides and ends, ia a instance where joints are bevelled to obtain the required shape of the article. In other cases an exterior surface may be bevelled in relation to other surfaces. e.g. tho top edge of a plinth. In furniture, edges are frequently chamfered, which means planing off the angles so that a narrow flat at the angle of 45° is formed. Parts meeting with a joint at 45°, such as the corners of picture-frames, are said to be mitred. A sloping joint uniting pieces in tho same plane is a scarfed or spliced joint. All come under the heading of bevelling.

As a general rule lines are marked on the work to show the exact extent of the required bevel, and the cutting tools work to these lines. In other cases appliances are used for guiding the tools. In sawing small pieces at an angle of 45° a mitre box or a mitre block [nay be used to guide the saw. For planing the angles two types of shooting boards are used. These may be for 45' only, or adjustable to any angle. One kind is used for planing long edges (Fig. 1), the other for short ends (Fig. 2). In both the plane is used lying on its side. It is slid backwards and forwords with the right hand, while the work is held in position with the left.

A woodworker's bevel is used for marking lines (Fig. 3) and testing(Fig. 4). The bevel is adjustable to any angle. and is tightened by a screwdriver or by a wing-nut. Definite angles are obtained from a protractor, or by drawing a full-size view of that portion of the work on paper. (Fig. 5) shows a type of bevel used chiefly by metal-workers. Besides this there are bevels in combination with protractors.
