Even oven-dried wood retains a small percentage of moisture, but for all except chemical purposes, may be considered absolutely dry. The general effect of the water content upon the wood substance is to render it softer and more pliable. A similar effect occurs in the softening action of water on rawhide, paper, or cloth. Within certain limits, the greater the water content, the greater its softening effect. Drying produces a decided increase in the strength of wood, particularly in small specimens. The greatest strength increase due to drying is in the ultimate crushing strength, and strength at elastic limit in endwise compression; these are followed by the modulus of rupture, and stress at elastic limit in cross-bending, while the modulus of elasticity is least affected.

Skirting boards How to remove paint from wood — 3 ways There are three ways of removing paint from wood: Sanding is best kept for small projects unless you want to hire an industrial sander to remove paint and varnish from your floor. A quick word about sandpaper and wire wool, both of which can cause damage to wood unless you take it easy… When you sand wood you take the surface off, and you need to do it as evenly as possible without rubbing it thin in places or creating gouges. Power tools help because their design forces you to apply even pressure. Bear in mind, also, that a hot air gun can only be used as a paint remover, not a varnish remover as varnishes tend to go very gooey, almost glue-like, when heated. Chemical stripping is the best method for stripping carved wood with hard-to-reach, intricate areas, but in reality you will probably use a combination of mechanical and chemical methods for your project, especially if you have layer-upon-layer of old paint to take off. Chemical paint removers deliver the best results, remove varnishes and paints faster than sanding, and tend to be the least harsh.

All about Pine Wood. A little history of Oak Oak or quercus as it is known in Latin is a hardwood with some known species. It has always been a popular wood in The UK, but in recent times it is even more widely used in construction and also as internal fixtures in clubs and gyms etc. For furniture construction oak has become ever more the wood of choice, a trend expanding year on year since the year when China, India and Indonesia substantially increased their export markets.
Etymology[ edit ] The noun mortise, "a hole or groove in which something is fitted to form a joint," comes from c. The first examples, tusked joints, were found in a well near Leipzig - the world's oldest intact wooden architecture. The oldest known use dates from the Early Neolithic Linear Pottery culture , where it was used in the constructing of the wooden lining of water wells. Many instances are found, for example, in ruins of houses in the Silk Road kingdom of Cadota , dating from the first to the fourth century BC.
