The router makes it possible to make chamfers, grooves, rabbets, tongues and to profile parts on edges or surface for decoration (molding). (Non-contractual photo, does not necessarily reflect the drawing)
It is therefore especially a machine for shaping assemblies and finishes. It also makes it possible to shape in end for the realization of tenons and assemblies with mid-wood by use of the tenoning carriage. This cart is generally offered as an accessory on all models. It actually works as a slide guide. The router shaft can accommodate a wide range of irons as well as grooving discs or even cylinders for sanding fretwork parts.
Characteristics of the router
The spindle rotates very quickly so that the wood is shaped properly and without luster (about 6000 rpm). The tree is characterized by its diameter (20 or 30 mm in general). Some irons can be mounted directly on the tree and secured by screws with lock nuts, caps and rings, without tool discs. The tree also receives strawberries, toolholders and even saws.
The molding work almost always require the use of a tool-holder, a sort of thicker disc of greater or lesser thickness, on which the irons are arranged in opposition, held in grooves by a flange, itself blocked by an impression screw with six hollow sections. There is a considerable range of irons, whose profiles can, in addition, be combined. In addition, it is always possible to make, or to make perform an iron to the particular profile. The height of the shaft is adjusted by handwheel which incorporates a locking handle.
The work table, 300 to 400 mm wide and 400 to 600 mm long, is generally made of cast aluminum and has a groove for fixing the angle guide. Each router model is characterized by the maximum diameter of the tools (150 mm, for example). This diameter defines, for example, the maximum length of the tenons or the maximum width of the rabbets. The diameter is given without wafer-light, that is to say a wafer which limits the opening in front of the shaft. Different wafers can be placed to reduce the diameter of the tools.
The top is equipped with protective guides. Two wood plates on either side of the shaft, in alignment with each other, make it possible to slide the pieces and protect the tools; they are adjustable laterally and in depth. A guard mounted on a stem and often with a transparent screen, is used for work on the tree.
Pressure springs with adjustable pressure keep the parts against the guides without putting your hands.
On the opposite side of the table, the shaft is protected by a transparent protective cover. Finally, a housing allows the directed ejection of chips. All these parts (housings, guides and protections) are removable and the tree can be completely cleared for certain works (sanding with the cylinder for example).
Work at the top is considered dangerous enough; the tools are mounted on a tree that protrudes on the table. The machine is therefore equipped with many organs and protection accessories that must necessarily be put in place. It is often necessary to machine the router small parts (for molding or grooving for example); the fingers are very exposed if the machine is not used correctly.
