A bench dog is a removable clamp used on a woodworking workbench to hold an item fast while being worked. It is characteristically used in concert with an adjustable dog on a bench vise , allowing an item compressed between the two to be held fast on each end, and if offset in both directions.
A form of bench dog, a traditional holdfast has either a curved or flat top. Its shank is slid loosely into a “dog” hole in the bench or anvil until the tip of its hook touches the work. It is set by hitting its top with a mallet or hammer, which causes the shaft to wedge tightly against the sides of the hole. A tap of its back side near ...
A mortise is a hole cut into a timber to receive a tenon. There are several kinds of mortise: [16] Open mortise: a mortise that has only three sides. (See bridle joint). Stub mortise: a shallow mortise, the depth of which depends on the size of the timber; also a mortise that does not go through the workpiece (as opposed to a "through mortise").
A chain mortiser used in timber framing. For cutting larger mortises such as those used in timber frame construction, chain mortisers are commonly used. A chain with cutters (similar to a chainsaw chain) rotating within a frame clamped to the work is successively plunged into the workpiece to mortise out the required volume.
Again, the term refers to the lock mechanism, so a lock can be both a mortise lock and a lever tumbler lock. In the modern lever tumbler lock, the key moves a series of levers that allow the bolt to move in the door. [5] Pin tumbler lock, commonly used for mortise locks in the US. The next major innovation to mortise lock mechanisms came in 1865.
If suitably square and flush, the stop that spans the full width of the bench hook (the hook) can also be used as a fence so the bench hook can be used as a short shooting board, for trueing the ends of pieces using a hand plane. [4] [2] A pair of bench hooks made to the same dimensions can be used in unison for supporting longer pieces of wood.
Pin-and-hook fastener. A mortise or slot is cut vertically in the bedpost. Pins are inserted horizontally in the bed post so that the pins perpendicularly intersect the mortise. For example, if one looked in the mortise, one might see part of one horizontal pin at the bottom of the mortise and a part of a second pin toward the top of the mortise.
The name bench lathe implies a version of this class small enough to be mounted on a workbench (but still full-featured, and larger than mini-lathes or micro-lathes). The construction of a center lathe is detailed above, but depending on the year of manufacture, size, price range or desired features, even these lathes can vary widely between ...
