The hull planking is also poorly preserved, but there were, however, thirteen strakes that may serve for extrapolation to the design of the entire ship. The strakes were fastened together by pegged mortise and tenon joinery and assembled in the classic shell-first construction. The spacing between mortises and the width of the mortises is very tight and they also appear to be slightly wider than the tenons. It is believed that the space left within the mortises was intended to compensate for possible misalignment of opposite mortises.

The correct use of a twybil is highly specialized, that of rapidly clearing out mortises. Mortises are rectangular holes used to take a tenon for several forms of joint, most obviously the common mortise and tenon joint. Mortises are always cut so that their long axis is along the grain of the wood. Traditionally these were first cut by drilling with a brace and bit to mark out each end, then the twybil used to break out the wood between them.

The railing pillars have images of Yaksha and three mortises carved on them. These pillars may have belonged to the same monument as the lens-shaped mortises because both have the same size, the color of the stone, distances between the three mortises carved on the pillars and yaksha carvings.Sonya Rhie Quintanilla, 2007, History of Early Stone Sculpture at Mathura: Ca. 150 BCE - 100 CE, page 67. The yaksha on the Bhadas pillar stands on protome of a Cloven hoofed animal, with the raised right hand (now-broken) holding a flower and the left hand on the hip holding up the drapery.

In traditional timber frame joinery, mortises and tenons were typically wide and from the edge of the timber when working with softwoods, giving rise to the width of the blade. Likewise, mortises and tenons were traditionally wide when working in hardwoods, explaining the width of the tongue. This allowed for quick layouts of mortise and tenon joints when working both hard and softwoods.

Both tools are used for levering out chunks when first clearing out a mortise and so have similarly shaped bevels, often with a curved bevel surface for a better fulcrum action. Slicks are other specialised chisels also used to work on the sides of mortises, but are used for final clean-up to make an accurate and smooth-sided mortise, after the rough chopping has been carried out. In the heyday of the twybil, mortises in small work were often round-ended and so could be cut very quickly by brace and twybil alone, the tenon being rounded to fit.Edlin, Woodland crafts, The curious break and tools used to form mortises in gate hurdles, figures 99 & 100, facing p.

For cutting small mortises, a normal drill bit can be used. However, for larger mortises, a common type of bit in modern mortisers is a Harry Watt square drill bit, in which a bit with a Reuleaux triangle cross section is allowed to "wobble" while it rotates within a square with rounded corners. This type of bit removes all but the corners of the material to be removed, leaving very little to be cut by the chisel.

A more recent innovation is the horizontal mortiser, which incorporates a router mounted statically on its side with the workpiece clamped to a multi-axis sliding table. This type of mortiser can produce either traditional mortise and tenon pairs, however it excels at floating (or 'loose') tenons. A floating tenon is where both the pieces of wood that are to be joined have aligned mortises cut into them and a separate piece of wood is milled into a fitted tenon which is glued into the two mortises.

Timber-framed construction, carefully fitted with mortises and tenons and dowelled together, set on stone footings, were the rule, replaced by stone buildings for the important ceremonial rooms. Traces of window glass have been found, as well as ironwork window grilles.

The horizontal timbers are tenoned into mortises chiseled into the posts. At each mortise and tenon is a chiseled-in guide symbol, consisting of a Roman numeral or other directional mark. Each corner has two interior diagonal braces. The four corner posts are tenoned into interlocking sill logs.

Ha'amonga 'a Maui is constructed from three coral limestone slabs. It is 5.2m high, 1.4m wide, and 5.8m long. The weight of the visible part of each upright stone is approximately 30–40 tons. Deep mortises are cut into the top of each upright stone to fit the lintel.

Technology Student which are designed to scribe parallel lines marking both sides of a mortise at the same time.What is MORTISE GAUGE? definition of MORTISE GAUGE (Science Dictionary). The Science Dictionary One of the pins is adjustable, attached to a sliding fence, so that mortises of different widths can be marked.

A third method was to nail planks either side of the wall plates to form a channel to hold the slabs, instead of mortising. This was a much quicker method of construction, but it required the use of sawn and dressed timber, and nails.Cox, pp. 47-48 Slabs were sometimes chamfered at one or both ends to fit into the mortises.

This tool, first on sale in 2007, cuts mortises in the manner of a biscuit joiner. A drill-like rotating cutter cuts a round-ended mortise. Each plunge creates a mortise that is sized to accept a Domino loose tenon, creating joints in stock from wide. There are five cutter sizes (4 mm, 5 mm, 6 mm, 8 mm and 10 mm) for six different Domino tenon sizes.

Though relatively rare now, two types are found in a number of regions in North America, more common are the walls with planks or timbers which slide in a groove in the posts and less common is a type where horizontal logs are tenoned into individual mortises in the posts. This method is not the same as the plank- frame buildings in North America with vertical plank walls.

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. The Makita 7104L is such a tool. These chains are made in varying widths, with numbers of chains in parallel.

Although built on a log cabin-style sub-structure, tongkonan are set on large vertical wooden piles with mortises cut into their ends to grasp the horizontal tie beams. The tops of the piles are notched for the longitudinal and transverse beams that support the upper structure. The remainder of the sub-structure is assembled in-situ. The transverse beams are fitted into the notched piles, and then notched to fit the longitudinal beams.

The original woodwork continues to the cabinetry in bedrooms which is made of butternut wood, a variety of walnut wood, most likely constructed from native walnut trees that were harvested on the property. The cabinetry is ornate, particularly for the period, and features Moorish flourishes. Outside, much of the house appears to have been built from materials salvaged from earlier structures. This is indicated by the presence of unused mortises in many of the main structural members.

The mortise chisel, even in its heavyweight "pigsticker" form, is used differently from a twybill, although the two may be used together. The twybill cuts the sides of mortices, along the grain. Its action is a splitting and prying one, so only requires a handle for leverage and is never struck. Mortise chisels are used for heavy chopping across the grain, are nearly always struck, and are used to square up the ends of square-ended mortises.

For example, when shaping the edge of a fine table top, many users prefer a D handle, with variable speed, as it seems to permit better control and burning the wood can be minimized. Routers have many uses. With the help of the multitude of jigs and various bits, they are capable of producing dovetails, mortises, and tenons, moldings of infinite varieties, dados, rabbets/rebates, raised-panel doors and frames, cutting circles, and so much more.

A half-blind dovetail joint Craftsmen use a 'half-blind dovetail' when they do not want the end grain visible from the front of the joint. The tails fit into mortises in the ends of the board that is the front of the item, hiding their ends. Half-blind dovetails are commonly used to fasten drawer fronts to drawer sides. This is an alternative to the practice of attaching false fronts to drawers constructed using through dovetails.

Most of the wheel's parts are pressure-treated wood, replacing original materials in a 1990-91 restoration. The axle of the wheel is cast iron, with a cast iron hub providing attachment mortises for the wheel's arms. The arms are fastened to the hub with metal bolts, and are cross braced with iron tie rods. The wheel was traditionally thought to date to the construction of Eli Terry's clock factory, which was built on this site in 1824.

The Paddington Reservoir is located on the south western side of the Oxford, Ormond and Oatley streets intersection. It is a large semisubmerged rectangular structure of brick construction supported by timber columns and overlaid by a grassed park. The reservoir was constructed of brick with ironbark columns which were erected in mortises in stone foundations at the base of the reservoir. These columns supported cast iron beams which in- turn supported segmental arches which formed the roof of the structure.

There are many types of woodworking chisels used for specific purposes, such as: ; Firmer chisel : has a blade with a thick rectangular cross section, making them stronger for use on tougher and heavier work. ; Bevel edge chisel : can get into acute angles with its bevelled edges. ; Mortise chisel : thick, rigid blade with straight cutting edge and deep, slightly tapered sides to make mortises and similar joints. ; Paring chisel : has a long blade ideal for cleaning grooves and accessing tight spaces.

Sylvan Retreat, also known as the J. H. Pumphrey Home, is a historic raised former plantation house at 610 N. 3rd Street in Gibsland in Bienville Parish, Louisiana. It was built in 1848 by William George Walker in another location, and was moved into Giblsland in 1884. It was listed on the National Register of Historic Places in 1979. It was built as a five-bay Greek Revival raised plantation house, with wood frame built of virgin cypress joined by mortises and pinned with wooden pegs.

Square chisel mortising bits can also be fitted to normal drill presses using a mortising attachment. The Greenlee Company still manufactures mortisers, as do a large number of other power tool manufacturers. It is a common tool in the woodshop of professional woodworkers, but because of its specialized nature, many amateur woodworkers would not make enough use of it to justify the moderately high cost and space this tool takes up in the woodshop. Some smaller and less expensive models, suitable for cutting only narrow mortises are available.

Drawing of a Tabletop DIY - CNC router. Silver: Iron, Red: Stepper Motors, Light Brown: MDF, Dark Brown: Hard Wood A computer numerical control (CNC) router is a computer-controlled cutting machine which typically mounts a hand- held router as a spindle which is used for cutting various materials, such as wood, composites, aluminium, steel, plastics, glass, and foams. CNC routers can perform the tasks of many carpentry shop machines such as the panel saw, the spindle moulder, and the boring machine. They can also cut joinery such as mortises and tenons.

A joist hanger. Joists may join to their supporting beams in many ways: joists resting on top of the supporting beams are said to be "lodged"; dropped in using a butt cog joint (a type of lap joint), half-dovetail butt cog, or a half- dovetail lap joint. Joists may also be tenoned in during the raising with a soffit tenon or a tusk tenon (possibly with a housing). Joists can also be joined by being slipped into mortises after the beams are in place such as a chase mortise (pulley mortise), L-mortise, or "short joist".

The community of d’Éguzon-Chantôme and Crozant had the desire of local authorities to initiate artistic and cultural projects in a remote rural areas based on the environmental qualities of its sites. Udo proposed Radeau d' Automne as a monumental sculpture designed with natural materials. In the shape of a stylized maple half-leaf, 6.80 meters long and 3.90 meters high, the work is built in round trunks with light chestnut wood, assembled "with the old "tenons, mortises and ankles. This traditional, solid and aesthetic blend, as well as the use of a local essence and strong identity, reinforces the link to the territory.

Green woodworking tools From the left: stichaxt or stossaxt, a German or Austrian pattern of mortice axe, kreuzaxt, a double ended German mortice axe with two types of chisel ( a sort of medium-sized twybil, like a smaller version of the French bisaigue - usually fitted with a short wooden handle) and adze Hurdle-maker's small twybil A twybil is a hand tool used for green woodworking. It is used for chopping out mortises when timber framing, or making smaller pieces such as gates. It combines chopping and levering functions in a single tool. The appearance of a twybil is that of a T-shaped double-edged axe with unusually long blades and a very short handle.

Piece-sur-piece also known as Post-and- plank style or "corner post construction" (and many other names) in which wood is used both for the frame and horizontal infill; for this reason it may be incorrect to call it "half-timbering". It is sometimes a blend of framing and log building with two styles: the horizontal pieces fit into groves in the posts and can slide up and down or the horizontal pieces fit into individual mortises in the posts and are pegged and the gaps between the pieces chinked (filled in with stones or chips of wood covered with mud or moss briefly discussed in Log cabin.) This technique of a timber frame walls filled in with horizontal planks or logs proved better suited to the harsh climates of Québec and Acadia, which at the same time had abundant wood. It became very popular throughout New France, as far afield as southern Louisiana. The Hudson's Bay Company used this technique for many of its trading posts, and this style of framing becoming known as Hudson Bay style or Hudson Bay corners.
