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. The Makita 7104L is such a tool. These chains are made in ...
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").
Frames can be constructed by several methods: cope and stick, mortise and tenon, bridle joint, or a simple butt joint. Cope and stick is the most common method, as it is more efficient to manufacture. Mortise and tenon is the strongest, and is often used for large doors which will have greater stresses imposed.
The original tool supported cutter sizes from 4 mm to 10 mm with available tenon sizes from 4x20 mm up to 10x50 mm. This allowed joints in stock as thin as 10 millimetres (0.39 in). Later a bigger tool was introduced allowing tenon sizes up to 14x140 mm, opening many carpentry use cases for the tool family.
Tools include dividers, axes, chisel and mallet, beam cart, pit saw, trestles, and bisaigue. The men talking may be holding a story pole and rule (or walking cane). Shear legs are hoisting a timber. Below, the sticks on the log are winding sticks used to align the ends of a timber. Tools used in traditional timber framing date back thousands of ...
Some mortise gauges are designed with one retractable spur, so that they can be used as marking gauges as well; [6] however, because the mortise gauge is an expensive and high precision tool, many carpenters prefer to have a separate marking gauge for general use. [5]
