Wood Mouldings: Door, Window, Handrails etc.
Door and window mouldings
Architraves cover joints between walls and the frames of doors, windows and built-in cupboards. Sizes range from about 19 x 50 mm (3/4 x 2 in) up to 25 x 75 mm (1 x 3 in) nominal.
Door drips throw rainwater away from the gap beneath the door.doors have drips, which are usually fitted by the maker on request.
The actual section varies from merchant to merchant, but the purpose of the drip remains the same.
Note that the base is not at 90° to the upright. The same effect can be achieved using a board with the front and rear edges cut at an angle, supported on three equally-spaced 45° blocks.
Casement and sash frames are normally. Use hardwood for outdoor sills. Standard stock sizes are usually bottom rail: 38 x 75 mm (1-½ x 3 in), 44 x 100 mm (1-3/4 x 4 in), 50 x 100 mm (2 x 4 in) nominal; sash stile: 38 x 50 mm (1-½ x 2 in), 44 x 50 mm (1-3/4 x 2 in), 50 x 50 mm (2 x 2 in) nominal; sash bar: 25 x 38 mm (1 x 1-½ in), 25 x 44 mm (1 x 1-3/4 in), 25 x 50 mm (1 x 2 in) nominal.
The joints are mitred or scribed, with mortise and tenon joints between members. The tenons are sometimes wedged or dowel-pinned, and the top and bottom rails are tenoned into the stiles.
Most merchants stock softwood sections with the ovolo moulding.
Glazing bars, handrails, scotia, dowels
Glazing bars: these are for building or repairing greenhouses. Use red- or white-wood bars if they are to be painted. Use cedar if you intend to oil them. Standard sizes of glazing bars are 38 x 50 mm (1-½ x 2 in), 38 x 75 mm (1-½ x 3 in) and 50 x 75 mm (2 x 3 in) nominal.
Picture-rails, of softwood, are usually nailed to the wall with cut.
Handrails, of hardwood or softwood, are joined to banisters and posts with mortise and tenon joints.
Curved or long handrails are butt-jointed end-to-end with handrail. Scotia and quadrant mouldings, in softwood or hardwood, are used in corners to cover gaps between skirting and floorboards and as glazing beads. Sizes from 6.5 x 6.5 mm (4 x 4 in) upwards.
Dowelling, which is widely used for joint-making, is available in hardwood and softwood in diameters from 3-50 mm (1/8 – 2 in). In hardwood it is more readily available in diameters from 6.5-25 mm (¼ – 1 in). Although nominally round, dowels may be slightly elliptical and may not fit tightly into holes drilled for them. Rebated half-round moulding is usually rebated to receive the thickness of. It is often used as a cover strip for panel edges.
Half-round is commonly used to hide the joint of two butting panels. It is not a true half-round. Sizes are 12, 19 and 25 mm (1/2, 3/4 and 1 in) across the flat face.
