Wood Filler
Wood putty, also called plastic wood, is a substance used to fill imperfections, such as nail (engineering), nail holes, in wood prior to wood finishing, finishing. It is often composed of wood dust combined with a binder (material), binder that dries and a diluent (thinner), and, sometimes, pigment. Pore fillers used for large flat surfaces such as wood flooring, floors or table (furniture), table tops generally contain silica instead of or in addition to wood dust. Pores can also be filled using multiple coats of the final finish rather than a pore filler. The main problem in using putty is matching the colour of the putty to that of the wood. Putties are usually sander, sanded after they dry before applying the finish. Many different brands, types, and colours are commercially available. Binders include lacquer, water-base, and linseed oil. Some woodworking, woodworkers make their own putty using fine sandpaper, sanding dust (not sawdust, which is too coarse) with wood glue or a ...

Nail (engineering)
In woodworking and construction, a nail is a small object made of metal (or wood, called a tree nail or "trunnel") which is used as a fastener, as a peg to hang something, or sometimes as a decoration. Generally, nails have a sharp point on one end and a flattened head on the other, but headless nails are available. Nails are made in a great variety of forms for specialized purposes. The most common is a ''wire nail''. Other types of nails include ''pins'', ''Thumbtack, tacks'', ''wikt:brad, brads'', ''spikes'', and ''cleat (shoe), cleats.'' Nails are typically driven into the workpiece by a hammer or nail gun. A nail holds materials together by friction in the axial direction and Shear stress, shear strength laterally. The point of the nail is also sometimes bent over or ''clinched'' after driving to prevent pulling out. History The history of the nail is divided roughly into three distinct periods: * Hand-wrought (forged) nail (pre-history until 19th century) * Cut nail (ro ...
