wooden-jointer-plane-dimensions-not-working In a workshop, it is preferred to have the outlets approximately 4 feet off the ground. These are typically boards which are too unwieldy or long to manoeuvre on a table saw. I've never used Miller Dowels before and I have to say, I'm delightfully impressed. This allows for very high penetration without excessive heat input from decreased weld metal deposited leading to less distortion wooden jointer plane dimensions not working welding at higher travel speeds.

It was mentioned earlier to install GFCI receptacles which sense if there is a dangerous ground path created and trips a breaker within the receptacle. Windows can be enlarged and replaced to provide more light to the workshop, otherwise adequate artificial lighting will need to be installed in the workshop area.

Most building codes mandate that a basement have secondary stairs to the upper floor. A stairwell with minimum steepness, and which is turned or split in the middle with a landing, is much safer than a steep, narrow, straight stairwell. A door that allows access to the basement directly from outside is preferable but not necessary.

Central heating will provide more than enough heat for the basement workshop, and additional heating ducts can be installed if necessary. Double-tube fluorescent lamps provide the best, brightest lighting, and are the most economical to operate continuously. A wood floor could be laid over the concrete floor to provide more comfort. Shown is an illustration of a wider, split stairwell. Although this stairwell includes a turn, it is much safer than the straight, narrow type.

The landing serves to break a fall and to rest heavier pieces as they are being brought in or removed from the basement workshop. I added the series of four photos to demonstrate how an area of a basement can be converted into a workshop space for woodworking.

This is vintage digital photography of one of my early workshops over 20 years ago. The workshop was enclosed with walls and a door to contain any dust generated and isolate it from the rest of the basement. A window was added later to allow ambient light from the rest of the basement to enter the workshop area. The workbench is essentially a structurally rigid table to work on.

It must be extremely reliable, both strong and rigid. The top should be very flat, and deep enough from front to back to accommodate your work. The overall height of the workbench should be emphasized, as it should be convenient for you to work on comfortably.

Workbenches can be purchased, but if you design and build one, it is best to follow an existing plan as many sensible details have already been incorporated into the design. Common features of a workbench are a tool recess at the rear of the top running lengthwise along the tabletop. The tool recess is to ensure that tools do not protrude into the workpiece above the level of the table top.

Other common features of the typical woodworking workbench are drawers or shelves under the work area, and two vises. Vises are very important because holding the workpiece firmly is essential to a good job. Often there is a vise face vise at the front of the bench and another at the end of the bench tail vise or shoulder vise. These vises work in conjunction with bench dogs to hold long or wide material firmly to the work surface.

The bench dog, shown in the second photo, is basically a square or round, wood or metal peg which is inserted at predefined holes in the surface of the workbench. Despite all this, ripping sawing lumber along the grain and working large boards is usually awkward on the workbench.

A pair of sawhorses is invaluable in the shop, on which you can rest the workpiece with plenty of overhang. A sawhorse is also handy in cross-cutting sawing across the grain.

Storage is another essential requirement of the workshop. Storage is used for hand tools, portable power tools, finishing materials, and small hardware. The third photo illustrates a typical woodworking bench with a front vise and storage underneath in a workshop setting. The height of the workbench should be adjusted for your individual comfort, because it is most often used by yourself. Stand straight and rest the palms of your hands on a surface just high enough so that your elbows are slightly bent.

This is your proper upper work height, and the bench should measure this distance from the floor. Bench heights range from 30 to 36 inches high. Tools should be in close proximity to the bench, ideally the wall behind the bench. A workbench should be comfortable and highly functional. The workbench can be placed in the middle of the shop; you can then work on four sides of the bench.

This arrangement leaves plenty of space for manoeuvring large workpieces around the bench. The workbench can also be placed against a wall or on the two sides of a corner. This arrangement leaves less room to manoeuvre large workpieces, but it offers accessible wall space for storing tools.

You can also take advantage of natural light if the bench is placed under or near a window. One of the photos below is that of a small compact bench which is well suited to working with smaller workpieces. At the front and side of the workbench vises are located which in conjunction with bench dogs are used to hold your work firmly down.

The tool tray running lengthwise at the back of the workbench is visible. This bench does not include any shelving or drawers beneath the bench top, but it is straightforward to construct or available to purchase, and is the ideal first small workbench for hand tool based operations.

The fourth photo is of a typical cabinetmakers workbench. This bench is much larger and has a tool drawer incorporated into the bench top. The side vise is actually a shoulder vise and offers more flexibility than the standard side vise. The length of the workbench offers the woodworker more flexibility in using longer work pieces. The last photo shows a collection of bench jigs used to fasten work to the workbench surface. The bench jigs are designed to fit into pre-existing bench dog holes.

The wide area of the jig surfaces keeps work pieces from rotating and makes it easier to hand plane small and medium-sized boards. The photos show typical metal woodworking vises which are attached to the underside of the bench top. Replaceable wood blocks are commonly attached to both faces of the metal jaws to prevent marring of the work piece from the metal jaws. Slide-up bars, which are essentially dogs, are located in the outward jaw.

This vise dog is used to secure long pieces of lumber against other dogs inserted in the bench top. A bench dog is inserted at the appropriate place on the bench, and the dog in the vise is raised to clamp the stock flat on the bench top.

This clamping system lies flush with the bench top, and permits long planing strokes or sanding operations. The metal vises below can be purchased in different sizes, depending on the size of the average work piece you will be working with. Workbenches are traditionally made from hardwoods like beech or maple, and many excellent models can be purchased.

Workbenches are expensive to purchase, whereas an inexpensive home-made version can be created for your exact requirements. The frame for the workbench is typically bolted together, as carriage bolts can periodically be tightened up. The second photo is a large capacity quick-release vise located at front left of bench. This vise has added hardwood jaws to eliminate metal contact with the wood being clamped.

Third photo shows a pair of back to back workbenches constructed of pine with a hardwood plywood surface. These benches each have two drawers and a metal vise.

This type of workbench with integrated tool storage is ideal for a small shop. I built these two workbenches over 20 years ago and have moved them to each of my shops and they are in use to this day in my most recent workshop as can be seen in the third photo. Fourth photo shows a top view of the two matching workbenches placed back to back to increase the available surface area of the tabletops. A dovetail jig is in the lower right hand corner.

Task lighting is also set up for this bench. Fifth photo shows the front view of another heavy-duty shop-built workbench. A heavy duty vise is installed at the left of the bench. The bench is constructed of pine with a hardwood plywood laminated top. Sixth photo shows the top left view of the shop-built workbench. The removable, adjustable Veritas surface vise is an effective substitute for a tail vise. Seventh photo shows the top right view of main workbench.

The last photo in the series shows a sliding deadman installed on the main shop-built workbench. The sliding deadman allows you to effectively support a longer board which is clamped into the face vise.

The sliding deadman slides along, is removable, and can handle boards and wider panels with ease. This feature allows a person to effectively plane the edge of a long board without additional assistance. Safety rules for a workshop can be summed up in one sentence. Treat your tools with understanding and respect. Do not be afraid of tools. If tools are correctly used, they will greatly increase your workmanship qualities. Most high-speed operations such as cutting with a tablesaw and routing produce wood chips and are very noisy.

Safety glasses and hearing protectors protect against these hazards. Do not remove or bypass the safety devices added to machinery such as tablesaws and jointers. Blade guards and splitters are there for a reason. Keep a fire extinguisher in the workshop.

There are different classes of fire extinguisher A,B,C to choose for wood and paper fires to chemical fires.

The second photo shows safety goggles and the third photo shows a variety of common safety glasses. The next or fourth photo shows an overhead blade guard for the tablesaw. This safety feature serves to prevent the hands and fingers of the operator from entering the danger zone close to the saw blade. This blade guard is adjusted to be close to the piece being cut. The fifth photo shows a tablesaw splitter.

This safety device serves to keep any lumber exiting the blade from binding and causing kickback. It keeps the saw kerf open for the whole saw cut. The serrated pawls keep any lumber from kicking back. Safety glasses are perfectly acceptable for the workshop since they provide shatterproof protection for the eyes. Ideally, safety goggles should be worn as they provide shatterproof glass protection for the eyes.

Safety glasses and goggles should also be tight fitting and sealed against dust. Dust is second nature to a woodworking shop and it permeates almost every open surface, both vertical and horizontal. Wearing sealed safety goggles ensures that dust will not coat the inside of the goggles and hinder vision at a critical time.

Eye safety gear is fairly inexpensive, and this should be the first piece of safety gear purchased. The substances used in the average workshop carry relatively few risks to health, especially if you are in contact with them for only a short time. On the other hand, many people are affected by wood dust. Some people are affected by dust from certain woods; others are instead affected by dust from woods in the form of allergic reactions.

Allergic reactions can range from wheezing, shortage of breath to skin rashes. Allergies can also be developed by constant exposure to wood dust, especially if the dust is very fine. The finer the dust is; the greater the likelihood of it being inhaled and aggravating the throat and lungs. Wood dust particles can be very fine, this fine dust floats in the air for a long time before settling.

This dust is also called airborne dust. If you feel sick when working with a particular wood or woods, consider an alternative wood. You may be able to use an alternative method of working or matching the wood, for example planing instead of sanding. Shown next is a photo of dust masks, which are used to prevent the inhaling of fine wood dust. The top dust mask is a regular paper dust mask, whereas the bottom mask is of the cartridge type which allows filtered air to enter the mouth area.

The dust mask or respirator is an equally important component of safety in the workshop. The woodworker should form a habit of wearing a dust mask when performing operations which generate much dust. The simplest dust mask is a paper mask which covers the nose and mouth and which is also disposable. The paper dust mask is very economical and can be purchased in large quantities.

The dust mask is held on with an elastic band around the head. The next version of the dust mask also covers the nose and mouth, but has instead, a small air cartridge which can also be replaced. The benefit if this system is a better fitting dust mask and the provision for the woodworker to breathe easier, since air is expelled through a valve system. At the other extreme, and for woodworkers who need maximum dust protection, is the air helmet.

This is a helmet worn over the head, and is effectively a sealed chamber in which you breathe in. The actual air you breathe is transferred to and from an air pack which fastens to your waist or to your back. This is a self-contained breathing apparatus, with built-in dust and fume filtering. Another fairly new development in shop dust control is the ceiling mounted dust filtration unit.

An air cleaner unit is a self-contained stage dust filtration system powered by a small, quiet motor which is sealed from the environment. This design effectively removes most airborne dust in a reasonable time frame. The cost is somewhat expensive initially, but only the bag filter unit needs replacement after a long period.

The other filters can be effectively vacuumed or washed. Shown is a shop-made ceiling mounted three stage air cleaner unit. The shop-built air cleaner uses integrated squirrel-cage blowers and triple filter system. A fairly recent innovation in shop dust control is the downdraft table.

This table consists of a large blower assembly, typically a furnace fan and squirrel cage blower assembly enclosed within a sealed area. The blower serves to supply a vacuum to the surface or top of the table. This is accomplished through a series of holes equally spaced throughout the top. The shop-built downdraft table in the photo is made to serve as an outfeed table and also to serve as a whole shop air filter. The whole shop air filter function is accomplished through a timer on the side which keeps the blower running for a period of time after some dusty woodworking operations such as sanding.

This downdraft table is a good example of maximizing space within a shop environment. The downdraft table, outfeed table and whole shop air filter are combined into one unit.

Next photo shows a cartridge type dust mask. This dust mask utilizes a filter system, and is oriented to keep dust away from the opening.

A dust mask and goggles or safety glasses should be mandatory safety items in any woodworking shop. Also shown is a photo of a series of different types of hearing protectors.

The noise levels generated by some power tools can reach upwards of db. The use of hearing protectors are highly recommended in a noisy workshop. Depending on the type of woodworking you perform, either completely hand-tool based or with the use of powered tools, hearing protection might or might not be necessary. If you perform router or table saw work, the noise levels in decibels can be extremely high, slowly deteriorating and damaging your hearing.

Some hearing protectors are more comfortable than others, and should always be tested in conjunction with eye safety gear. A low cost alternative to earmuff style protection are common earplugs.

These plugs can achieve a high level of noise reduction, upwards of 25db. These plugs are disposable, but ideally earmuff style protection offers the greatest protection, as the ears are then completely enclosed against loud noise.

Safety glasses and ear protection should be worn as often as possible while working in a woodworking shop environment. Certain woodworking operations can be grouped to use one machine, and the required safety gear can then be worn at that time. Disposal of oily rags and rags soaked in finishing materials becomes important in a woodworking shop environment. The temperature of oily rags when bunched together gradually increases to the point of spontaneous self-combustion.

This is directly related to the chemical drying action of the oily finish itself. All oil based finish containers utilizing chemical driers such as boiled linseed oil have large warning markings on the can to point this out. As a precaution, all woodworking shop environments utilizing these types of finishes, or chemical finishes of any nature should have an oily waste rag container in the shop. The oily waste cans seal the rags from ambient oxygen and therefore keep the rags from self-igniting.

Many woodworking shops have burned down when this relatively simple step has been overlooked. The photo shows a typical oily waste can container. The oily waste can container is used to contain and dispose of oily rags used to apply finish to wood. It is critical to keep at least one fire extinguisher in the workshop. Most insurance companies mandate that woodworking shops have fire extinguishers readily accessible.

In my own 2-level woodworking shop, I have a fire extinguisher located at the entrance to each of the levels. The area directly around the fire extinguisher is kept tidy so the extinguisher can be quickly grabbed in the event of a fire.

A wall-mounted fire extinguisher can be seen in the last photo. Often, you will purchase lumber or sheet goods in large sizes. It is much more economical to purchase lumber without any processing.

Particles which precipitate in the vicinity of the mouth and eyes, and get into the organism, are defined as the inhalable fraction, that is total dust. Smaller fractions, penetrating into the non-cartilage respiratory tract, are defined as respirable dust. The parameter most commonly used to characterize exposures to wood dust in air is total wood dust concentration, in mass per unit volume. A study to estimate occupational exposure to inhalable wood dust by country, industry, the level of exposure and type of wood dust in 25 member states of the European Union EU found that in —, about 3.

The highest exposure levels were estimated to occur in the construction sector and furniture industry. Wood dust is known to be a human carcinogen, based on sufficient evidence of carcinogenicity from studies in humans. It has been demonstrated through human epidemiologic studies that exposure to wood dust increases the occurrence of cancer of the nose nasal cavities and paranasal sinuses.

An association of wood dust exposure and cancers of the nose has been observed in numerous case reports, cohort studies, and case control studies specifically addressing nasal cancer. Water-borne bacteria digest organic material in leachate, but use up much of the available oxygen.

This high "biological oxygen demand" can suffocate fish and other organisms. There is an equally detrimental effect on beneficial bacteria, so it is not at all advisable to use sawdust within home aquariums, as was once done by hobbyists seeking to save some expense on activated charcoal.

Sawdust is flammable and accumulations provide a ready source of fuel. Airborne sawdust can be ignited by sparks or even heat accumulation and result in explosions. At sawmills , unless reprocessed into particleboard, burned in a sawdust burner or used to make heat for other milling operations, sawdust may collect in piles and add harmful leachates into local water systems, creating an environmental hazard.

This has placed small sawyers and environmental agencies in a deadlock. Questions about the science behind the determination of sawdust being an environmental hazard remain for sawmill operators though this is mainly with finer particles , who compare wood residuals to dead trees in a forest. Technical advisors have reviewed some of the environmental studies, but say most lack standardized methodology or evidence of a direct impact on wildlife.

They don't take into account large drainage areas , so the amount of material that is getting into the water from the site in relation to the total drainage area is minuscule. Other scientists have a different view, saying the "dilution is the solution to pollution" argument is no longer accepted in environmental science. The decomposition of a tree in a forest is similar to the impact of sawdust, but the difference is of scale.

Sawmills may be storing thousands of cubic metres of wood residues in one place, so the issue becomes one of concentration. But of larger concern are substances such as lignins and fatty acids that protect trees from predators while they are alive, but can leach into water and poison wildlife.

Those types of things remain in the tree and, as the tree decays, they slowly are broken down. But when sawyers are processing a large volume of wood and large concentrations of these materials permeate into the runoff, the toxicity they cause is harmful to a broad range of organisms.

To lower the concentration of airborne dust concentrations during woodworking, dust extraction systems are used. These can be divided into two types. The first are local exhaust ventilation systems, the second are room ventilation systems.

Use of personal respirators , a form of personal protective equipment , can also isolate workers from dust. These rely on air pulled with a suction force through piping systems from the point of dust formation to a waste disposal unit.

LEV systems consist of four elements: dust hoods at the point of dust formation, ventilation ducts, an air cleaning device waste separator or dust collector and an air moving device a fan, otherwise known as an impeller. The impeller is usually built into, or placed close to, the waste disposal unit, or dust collector. Guidelines of performance for woodworking LEV systems exist, and these tie into occupational air quality regulations that exist in many countries.

This high velocity is accompanied by airflows often less than 0. Festool is one manufacturer of portable power tools using LVHV ventilation integrated into the tool design. If suitably designed, general ventilation can also be used as a control of airborne dust. General ventilation can often help reduce skin and clothing contamination, and dust deposition on surfaces. Within industry, many countries have air quality regulations. This is to help ensure that wood dust is extracted to a level that ensures specified maximum allowable residual airborne dust concentrations and worker exposure levels.

Early contact with Arab ships in the Indian Ocean during Austronesian voyages is also believed to have resulted in the development of the triangular Arabic lateen sail. Early Egyptians also knew how to assemble planks of wood with treenails to fasten them together, using pitch for caulking the seams. The " Khufu ship ", a Early Egyptians also knew how to fasten the planks of this ship together with mortise and tenon joints.

The oldest known tidal dock in the world was built around BC during the Harappan civilisation at Lothal near the present day Mangrol harbour on the Gujarat coast in India. Other ports were probably at Balakot and Dwarka. However, it is probable that many small-scale ports, and not massive ports, were used for the Harappan maritime trade.

The ships of Ancient Egypt's Eighteenth Dynasty were typically about 25 meters 80 ft in length, and had a single mast , sometimes consisting of two poles lashed together at the top making an "A" shape.

They mounted a single square sail on a yard , with an additional spar along the bottom of the sail. These ships could also be oar propelled. The ships of Phoenicia seem to have been of a similar design. The Chinese built large rectangular barges known as "castle ships", which were essentially floating fortresses complete with multiple decks with guarded ramparts. However, the Chinese vessels during this era were essentially fluvial riverine.

True ocean-going fleets did not appear until the 10th century Song dynasty. There is considerable knowledge regarding shipbuilding and seafaring in the ancient Mediterranean. The ancient Chinese also built ramming vessels as in the Greco-Roman tradition of the trireme , although oar-steered ships in China lost favor very early on since it was in the 1st century China that the stern -mounted rudder was first developed.

This was dually met with the introduction of the Han Dynasty junk ship design in the same century. It is thought that the Chinese had adopted the Malay junk sail by this period, [29] although a UNESCO study argues that the Chinese were using square sails during the Han dynasty and adopted the Malay junk sail later, in the 12th century. The Malay and Javanese people , started building large seafaring ships about 1st century AD.

Large ships are about 50—60 metres — ft long, had 5. This type of ship was favored by Chinese travelers, because they did not build seaworthy ships until around 8—9th century AD. Southern Chinese junks were based on keeled and multi-planked Austronesian jong known as po by the Chinese, from Javanese or Malay perahu - large ship. This is different from northern Chinese junks, which are developed from flat bottomed riverine boats. Archeological investigations done at Portus near Rome have revealed inscriptions indicating the existence of a 'guild of shipbuilders' during the time of Hadrian.

Until recently, Viking longships were seen as marking a very considerable advance on traditional clinker -built hulls of plank boards tied together with leather thongs. Haywood [39] has argued that earlier Frankish and Anglo-Saxon nautical practice was much more accomplished than had been thought, and has described the distribution of clinker vs.

The ship was 26 metres 85 ft long and, 4. Upward from the keel, the hull was made by overlapping nine strakes on either side with rivets fastening the oaken planks together. It could hold upwards of thirty men. Sometime around the 12th century, northern European ships began to be built with a straight sternpost , enabling the mounting of a rudder, which was much more durable than a steering oar held over the side.

Development in the Middle Ages favored "round ships", [41] with a broad beam and heavily curved at both ends. Another important ship type was the galley which was constructed with both sails and oars.

The first extant treatise on shipbuilding was written c. He wrote and illustrated a book that contains a treatise on ship building, a treatise on mathematics, much material on astrology, and other materials. His treatise on shipbuilding treats three kinds of galleys and two kinds of round ships.

Outside Medieval Europe, great advances were being made in shipbuilding. The mainstay of China's merchant and naval fleets was the junk , which had existed for centuries, but it was at this time that the large ships based on this design were built. During the Sung period — AD , the establishment of China's first official standing navy in AD and the enormous increase in maritime trade abroad from Heian Japan to Fatimid Egypt allowed the shipbuilding industry in provinces like Fujian to thrive as never before.

The largest seaports in the world were in China and included Guangzhou , Quanzhou , and Xiamen. In the Islamic world, shipbuilding thrived at Basra and Alexandria , the dhow , felucca , baghlah and the sambuk , became symbols of successful maritime trade around the Indian Ocean ; from the ports of East Africa to Southeast Asia and the ports of Sindh and Hind India during the Abbasid period. At this time islands spread over vast distances across the Pacific Ocean were being colonised by the Melanesians and Polynesians, who built giant canoes and progressed to great catamarans.

Shipbuilders in the Ming dynasty primarily worked for the government, under command of the Ministry of Public Works. During the early years of the Ming dynasty, the Ming government maintained an open policy towards sailing.

Between and , the government conducted seven diplomatic Ming treasure voyages to over thirty countries in Southeast Asia, India, the Middle East and Eastern Africa. Six voyages were conducted under the Yongle Emperor's reign, the last of which returned to China in After the Yongle Emperor's death in , his successor the Hongxi Emperor ordered the suspension of the voyages. The seventh and final voyage began in , sent by the Xuande Emperor.

Although the Hongxi and Xuande Emperors did not emphasize sailing as much as the Yongle Emperor, they were not against it. This led to a high degree of commercialization and an increase in trade.

Large numbers of ships were built to meet the demand. The Ming voyages were large in size, numbering as many as ships and 28, men. Shachuan , or 'sand-ships', are ships used primarily for inland transport.

It is said in vol. The shipyard was under the command of Ministry of Public Works. The shipbuilders had no control over their lives. The builders, commoner's doctors, cooks and errands had lowest social status. There were two major ways to enter the shipbuilder occupation: family tradition, or apprenticeship.

If a shipbuilder entered the occupation due to family tradition, the shipbuilder learned the techniques of shipbuilding from his family and is very likely to earn a higher status in the shipyard. Additionally, the shipbuilder had access to business networking that could help to find clients.

If a shipbuilder entered the occupation through an apprenticeship, the shipbuilder was likely a farmer before he was hired as a shipbuilder, or he was previously an experienced shipbuilder. Many shipbuilders working in the shipyard were forced into the occupation. The ships built for Zheng He's voyages needed to be waterproof, solid, safe, and have ample room to carry large amounts of trading goods.

Therefore, due to the highly commercialized society that was being encouraged by the expeditions, trades, and government policies, the shipbuilders needed to acquire the skills to build ships that fulfil these requirements. Shipbuilding was not the sole industry utilising Chinese lumber at that time; the new capital was being built in Beijing from approximately onwards, [44] which required huge amounts of high-quality wood.

These two ambitious projects commissioned by Emperor Yongle would have had enormous environmental and economic effects, even if the ships were half the dimensions given in the History of Ming. Considerable pressure would also have been placed on the infrastructure required to transport the trees from their point of origin to the shipyards.

Shipbuilders were usually divided into different groups and had separate jobs. Some were responsible for fixing old ships; some were responsible for making the keel and some were responsible for building the helm. After , the Ming government reversed its open maritime policies, enacting a series of isolationist policies in response to piracy.

The policies, called Haijin sea ban , lasted until the end of the Ming dynasty in During this period, Chinese navigation technology did not make any progress and even declined in some aspect. Documents from for example, refer to watercraft on the Sierra Leone river, carrying men.

Others refer to Guinea coast peoples using war canoes of varying sizes — some 70 feet in length, 7—8 feet broad, with sharp pointed ends, rowing benches on the side, and quarter decks or focastles build of reeds. The watercraft included miscellaneous facilities such as cooking hearths, and storage spaces for the crew's sleeping mats. From the 17th century, some kingdoms added brass or iron cannons to their vessels. The city-state of Lagos for instance, deployed war canoes armed with swivel cannons.

With the development of the carrack , the west moved into a new era of ship construction by building the first regular oceangoing vessels. In a relatively short time, these ships grew to an unprecedented size, complexity and cost. Shipyards became Wooden Jointer Plane For Sale Nyu large industrial complexes and the ships built were financed by consortia of investors.

These considerations led to the documentation of design and construction practices in what had previously been a secretive trade run by master shipwrights, and ultimately led to the field of naval architecture , where professional designers and draftsmen played an increasingly important role.

The ships of the Napoleonic Wars were still built more or less to the same basic plan as those of the Spanish Armada of two centuries earlier but there had been numerous subtle improvements in ship design and construction throughout this period.

For instance, the introduction of tumblehome ; adjustments to the shapes of sails and hulls; the introduction of the wheel; the introduction of hardened copper fastenings below the waterline; the introduction of copper sheathing as a deterrent to shipworm and fouling; etc. Though still largely based on pre-industrial era materials and designs, ships greatly improved during the early Industrial Revolution period to , as "the risk of being wrecked for Atlantic shipping fell by one third, and of foundering by two thirds, reflecting improvements in seaworthiness and navigation respectively.

One study finds that there were considerable improvements in ship speed from to "we find that average sailing speeds of British ships in moderate to strong winds rose by nearly a third.

Driving this steady progress seems to be continuous evolution of sails and rigging, and improved hulls that allowed a greater area of sail to be set safely in a given wind. By contrast, looking at every voyage between the Netherlands and East Indies undertaken by the Dutch East India Company from to , we find that journey time fell only by 10 per cent, with no improvement in the heavy mortality, averaging six per cent per voyage, of those aboard.

Initially copying wooden construction traditions with a frame over which the hull was fastened, Isambard Kingdom Brunel 's Great Britain of was the first radical new design, being built entirely of wrought iron. Despite her success, and the great savings in cost and space provided by the iron hull, compared to a copper sheathed counterpart, there remained problems with fouling due to the adherence of weeds and barnacles.

As a result, composite construction remained the dominant approach where fast ships were required, with wooden timbers laid over an iron frame Cutty Sark is a famous example. Later Great Britain ' s iron hull was sheathed in wood to enable it to carry a copper-based sheathing.

Brunel's Great Eastern represented the next great development in shipbuilding.
