Zeehan & North East Dundas Tramway Bogie 1896 The North East Dundas Tramway (NEDT) was a 2 ft (610 mm) narrow gauge tramway on West Coast Tasmania that ran between Zeehan and Deep Lead (now Williamsford). It was part of Tasmanian Government Railways. The line was opened in 1896 to carry ore from the Williamsford mines to Zeehan where it would be loaded onto another train for shipment to Burnie. The narrow-gauge (2 ft) was chosen because of the extremely difficult terrain that the railway crossed, requiring several big trestle bridges, including one at the foot of Montezuma Falls. After some rain the engine and carriages would get soaked by spray from the falls. There was a break-of-gauge with the mainline 1,067 mm (3 ft 6 in) system at Zeehan. The railway was closed in 1932. The rolling stock for the Tramway was built in the Launceston Railway workshops, and comprised twenty five eight-wheel low-side trucks, tare 3 tons 1 cwt. 1 qr., load 10 tons; six eight-wheel flat trucks, tare 2 tons 18 cwt. 1 qr., load 10 tons; two four-wheel bolster trucks, for carrying long timber, tare 1 ton 19 cwt., load 5 tons; and four passenger cars, each with six cross-seats with reversible backs, to carry eighteen passengers, also a locker for mails and parcels. All trucks and cars have cast-steel wheels 21 inches in diameter and are fitted with automatic vacuum brakes. The trucks have side levers and the cars have hand-screw brakes. The vacuum brake can be worked from the engine or from the passenger cars, which act as brake vans. When this brake was introduced, one effect was to accelerate the journey speed by about 10 minutes owing to more even running on down gradients.

Railway tracks are produced straight. They may appear to be easy to bend and may appear flexible, but are required to be bent for curves, at rail joins on curves and at point (turn-out) junctions. For a safe transition around curves and in the finer areas of the point, this was required to be done with a manual rail bender. Sometimes referred to as a Jim Crow, the rail bender attaches its two claws to the rail. In the middle of the two claws is a screw that is slowly tightened using a crow-bar to bend the rail. Tightening the screw too fast or too tightly may not give the structure of the rail time to redistribute and the rail may break if not done properly.Victorian Railways Permanent Way and Works track equipment Light Rail Bender narrow GaugeCast iron semi-circular tool, with hooked ends and central screw shaft.puffing billy, rail bender, jim crow

Marking Gauge. Manufactured by Marples of Sheffield, England. Also known as a scratch gauge, it is used in woodworking and metalworking to mark out lines for cutting or other operations. The purpose of the gauge is to scribe a line parallel to a reference edge or surface. The gauge consists of a beam, a headstock, and a scribing or marking implement, typically a pin, knife, pen or wheel. The headstock slides along the beam, and is locked in place by various means: a locking screw, cam lever, or a wedge.Maker's namemarking gauge, measuring tools, marples of sheffield

An hourglass or sandglass is an instrument for measuring a defined time and can be used perpetually by simply turning it over immediately the top bulb empties. The clear blown glass is shaped into two equal sized bulbs with a narrow passage in the centre and contains uniform sized sand or glass particles in the lower bulb. The width of the neck regulates the constant flow of the particles. The glass is held in a stand with top and bottom of equal shape and size. Hourglasses can measure an infinite variety of time by gauging the size of the particles, the shape and size of the bulbs and the size of the passage between the bulbs, thus measuring hours or minutes or even seconds. Generally an hourglass sits between discs of wood at the ends, which are joined by long wooden spindles between the ends and tightened by screw caps. The length of time can be adjusted by adding or removing sand particles. The use of the marine sandglass (or hourglass) has been recorded in the 14th century in European shipping. A one minute sandglass was used in conjunction with the ship’s log for ‘dead reckoning’, (see below) that is, for measuring the ship’s speed through the water. They were also used to regulate ringing the ship’s timetable; for example a 4 hour sandglass was used for the length of the sailors’ watch, and a half hour timer for taking of readings for the ship’s log; the ship’s bell would be rung every half hour. It was usually the role of the cabin boy to watch and turn the sandglasses over at the exact time of them emptying their upper chambers and to ring the ship’s bell. Hourglasses have been used historically for many hundreds of years. Some have been used for timing church sermons, in cooking, in industry and at sea. Even today they are used for measuring the cooking time of eggs and timing a player’s turn in games such as Boggle and Pictionary. The sandglasses at sea were gradually replaced in the late 1700’s to early 1800’s by the more accurate chronometers (marine clocks) when they became reliable instruments. DEAD RECKONING (or Deduced Reckoning) Dead reckoning is the term used to describe the method of calculating the ship’s position from its speed and direction, used in early maritime travel, mostly in European waters. Both the (1) speed and the (2) direction of travel were recorded on a Traverse Board at half-hourly intervals during a helmsman’s watch of 4 hours. The navigator would record the readings in his ship’s log, plot them on his navigational chart and give his updated course directions to the next helmsman on watch, along with the cleared Traverse Board. This was a very approximate, but none-the-less helpful, method of navigation. The wooden Traverse Board was a simple pegboard with a diagram of a compass with eight peg holes along the radius to each of the compass points, plus a grid with ascending half hours in the left column and increasing ship’s speed in knots in a row across the column headings, with a peg hole in each of the intersecting cells. A number of wooden pegs were attached to strings on the board. By placing one peg consecutively in the direction’s radius hole, starting from the centre, and the speed holes when the half hourly reading was taken, a picture of speed and direction for the whole 4 hour watch was created. (1) To measure the ship’s speed a one minute hourglass timer was usually used to measure the ship’s speed through the water and help to calculate its longitude. A rope, with knots at regular standard intervals and a weight such as a log at the end, would be thrown overboard at the stern of the ship. At the same time the hourglass would be turned over and a seaman would start counting the number of knots on the rope that passed freely through his hands as the ship travelled. When the timer ran out the counting would be stopped. A timer of one minute (one-sixtieth of an hour), knots spaced one-sixtieth of a nautical mile apart, and simple arithmetic easily gave the speed of the ship in nautical miles per hour ("knots"). This would be recorded every half hour. The speed could however be inaccurate to the travel being affected by ocean currents and wind. (2) To calculate the ship’s direction a compass sighting would be recorded each half hour.Marine hourglasses or sandglasses were used from around the 14th to 19th century during the time of sailing ships. This hourglass is representative of that era, which is during the time of the colonisation of Australia. Hourglass or sandglass; an instrument used to measure time.
