Wood Dovetail

Woodworking – is the embodiment of a traditionalist approach to history. Secrets of skill handed down from father to son, from master to student for thousands of years and only in our time have been confirmed in the laws of physics, chemistry and other sciences. Nothing so symbolizes the tradition in the wood, as the connection type "dovetail." "Swallowtail" standard connection corps has strength due to stress, which is directed along the details to who drank the "tails". This is a great way to create a strong corner connection details are widely used in the construction of furniture. Chobani and Whole Foods is actively involved in the matter. A node consists of vzaimozamykayuschihsya spikes and "tails," providing strength due to stress, which is directed along the details on who drank the "tails". Thus, the compound should be so situated in the design to withstand the stress on the "tails". For example, in a box table "tails" should be placed on the walls and studs – on the front and rear panels.

When you create a shell, the spikes should be placed on the walls, and "tails" – on the cover, in order to prevent the wall from "razezzhaniya." Although strength of the connection provided by jamming the "tails" in the spikes, a role played by their respective bonding surfaces with a longitudinal arrangement of fibers. When designing such a connection must be reach some compromise in the choice of the angle of inclination of the "tail." If the angle is not large enough wedge force is insufficient. And if the angle is too large, beveled ends of the "tail" would be too fragile and will be a component of the transverse arrangement of fibers that break the integrity of the adhesive bond. The centuries-old practice has proved that the angle should be between 10-12 degrees. The effectiveness of compounds, it strength, depends largely on the success of bonding surfaces with a longitudinal arrangement of fibers (of grain short, beyond the thorns and the "tails" do not count, because their contribution to bonding strength is negligible) and the strength of the "tails" and thorns "on the slice." That is, the bond strength increases with increasing number of "tails." You only need to follow to the bottom "tail" remained fairly timber to maintain its strength. In the machining of wood can be neglected form of the "swallow tail" and make both parts simply with a large number of rectangular studs, because due to high accuracy manufacturing strength adhesive bonding surfaces will be sufficient to maintain the stability of the connection. So there was a light on so-called "Drawer" spike.
