Tools And how to use them

Screwing into wood How does a screw work?

Stripping the head The most common mistake made when using a screw is stripping the head. Usually this happens because: The driver is not “seated” properly in the head Not enough force An odd angle Force is not constant Wood is too hard, drill too weak (battery dying), or screw is too long and needs more power behind it

How to Screw into wood

Nails A nail, rivet, bolt, or wooden dowel can perform similar functions. The object is to secure wooden members together and prevent them from moving. Nails do this by opposing the weight of the structure with their own resistance to shearing off. In order for a nailed board to move, it must either cut off or extract the nail, or the wood itself can break. The weakest form of nailing is when the weight is trying to pull the nail out of the board. The nail can still oppose this because the nailed wood is applying friction to the circumference of the nail. Where this would not be enough to keep the nail in, screws are usually used instead.

Nails The parts of the nail are the head, shank or shaft, point, and the gripper marks – slight grooves incised into the shank near the head of most (but not all) varieties of nails. The nail functions by displacing wood fibers when it is pounded into the work piece, and the pressure exerted against the shaft by the displaced wood provides the holding power. (Friction)

Nails Nails are sometimes referred to by their length in inches, but more often the traditional terminology of the penny is used. Dating from the days when nails cost a lot more than they do today, the term penny identifies the size of a nail. In an earlier era, one hundred nails of a certain size cost three pennies; hence the name “threepenny nail.” One hundred nails of the next size cost four pennies, and so on. The pricing structure has long since been abandoned (today, nails are sold by the pound), but the nomenclature of the penny survives. The word penny is often abbreviated in the British style by the letter d (for denarius, a Roman coin) — as in “3d nails,” for example, to identify “threepenny nails.” Nails shorter than one inch are generally identified by fractions of an inch rather than by pennies.

Types of Nail Common Nail. As the name suggests, these are your everyday nails. Used for rough construction work, the common nail can be purchased in lengths varying from one to six inches (2d to 60d). The largest common nails are colloquially known as spikes. Box Nail. These look like common nails, but are thinner. This means they are less likely to cause splits in the wood; as they displace less wood, they also have less holding power, so are not generally used where structural strength is critical. Box nails are generally available in lengths from one inch to three and a half inches. Casing Nail. A near relation of the finishing nail, the casing nail is slightly larger and has increased holding power. It is most often used for attaching moldings such as window and door casings where added strength is required. Finishing Nail. Finishing nails are (surprise, surprise) used for finish work. When the nailhead will show in the final product (as with moldings, for example), finishing nails are often used because their barrel-shaped heads are small and can be driven below the surface of the wood using a nail set (a technique called countersinking). Brad. Brads are essentially diminutive finishing nails, propor­tionately smaller in diameter and length (one inch or less). They are used in making frames, attaching plywood paneling, and in cabinet­work.

Hammers and how to use them

Nail Gun – The power/speed option Nail guns are excellent tools for repeated nailing or stapling. They are MUCH faster than hammering However, there is an added element of danger

Some Nail Gun Safety Suggestions

Toe-Nailing From Wikipedia, the free encyclopedia Toenailing or skew-nailing is to drive a nail at a slant or skew (between 20 to 30 degrees) with the initial surface in order to permit it to penetrate into a second member. It is a popular technique that carpenters use on a regular basis. The fasteners, used in pairs, nails or screws, are driven in on opposing angles. This locks the timbers together, to create a stable framework, e.g. in stud walls (partitions) or roof framing. The angled nailing makes later dismantling difficult or destructive. One of the most common places to toenail a framing member is where a rafter meets the top plate of a wall at the birdsmouth. Alternatives to toenailing include the use of hurricane ties, joist hangars, and other engineered steel connectors that permit nails to be attached perpendicular to a member's surface.nailsurfacecarpentersbirdsmouthhurricane ties When toenailing, nails can be driven from the inside or outside of the joint, depending on access available to use the hammer. Skew nailing is also a technique used by other woodworkers, for example a drawer or box can be glued and skew- nailed with finer nails or panel pins. Skew nailing will fasten the joint, while the glue sets, avoiding the use of clamps. A variation of toenailing is the use of screws for the same purpose, which might be called toenailing or toe-screwing.
