This hollow core bit has hard cutting inserts for drilling into rock. It was used to drill and recover 50mm diameter (most common size) rock cores. The rock cores were assessed by geologists and engineers to provide information for design of structures such as tunnels, dams and underground power stations (eg. McKay Creek Power Station, West Kiewa Power Station). This type of bit was also used where damage to the surrounding rock had to be minimised. The Diamond Drill Bit,used in the early 1900's, when it was primarily used as a method of sampling rock for ore deposits and oil exploration resulting in a "coring" of rock. The use of "coring" to obtained samples for the SEC Kiewa Hydro Electricity Scheme(1920's onward) was to analyse the core to obtain temperature and rainfall patterns shown by the levels of layered solidified soil(rock). This diamond drill would have been used in the early 1900's to provide a sub strata map of temperature and water patterns (over an long period of time). This was a pre requisite to any decisions about the viability of the region to provide the water needed for a successful hydro electricity scheme.This diamond drill for core sampling was at the forefront of the analysis whether to construct a hydro electrical facility in the Kiewa Valley and the adjoining alpine region. The rock core samples produced were assessed by geologists and structural engineers. It was only after extensive core drilling covering the region that solid scientific evidence could be provided to start the "SEC Vic Hydro Electricity Scheme" within its current boundaries.This "diamond" drill bit has eight "teeth" at its cutting edge. The drill creates an 55mm hole in extremely hard rock material to obtain 50mm core samples.. Three quarters down the shank it has thread screw channels to attach the bit to the drill pipe. The coring pipe attaches via screwing it onto this bit. Core samples are the main objective of this tool.alternate energy supplies, alpine feasibility studies temperature, rainfall, sec, kiewa hydro electric scheme, electricity

The semi-mythical stream, the Cooroopajerrup Creek. Before there were any channel banks and formed roads, this creek shared the Avoca flood waters with the Tyrrell Creek. In more recent times the Wycheproof channel prevented the major floods of 1956 and 1973 from following the old river course. Also there is said to have been some shifting of the sand-hills at Teddywaddy which have blocked much of the old Cooroopajerrup flow. Little is known of earlier records, but The Mount Wycheproof Ensign records flooding of the creek in 1909. 2011 saw the Cooroopajerrup flow again after 88 years. This 2011 photo was taken at about the same position as the 1923 photo. The modern steel roadway fence is submerged. see-Photograph-Record No 001997.Copy of a B&W photograph of the Cooroopajerrup-Creek in flood-1923.

The Great Bath is a massive pool, lined with 45 sheets of lead, and filled with hot spa water. It once stood in an enormous barrel-vaulted hall that rose to a height of 40 metres. For many Roman visitors this may have been the largest building they had ever entered in their life. The bath is 1.6 metres deep, which was ideal for bathing, and it has steps leading down on all sides. Niches around the baths would have held benches for bathers and possibly small tables for drinks or snacks. A large flat slab of stone is set across the point where hot water flows into the bath. It is known today as the diving stone. The Roman Baths complex is a site of historical interest in the English city of Bath. The house is a well-preserved Roman site for public bathing. The Roman Baths themselves are below the modern street level. There are four main features: the Sacred Spring, the Roman Temple, the Roman Bath House and the Museum, holding finds from Roman Bath. The buildings above street level date from the 19th century. Sepia postcard of a section of the Great Roman Bath at Bath, Somerset featuring the Diving Stone.printed verso: The Diving Stone in the great roman bath.

The Sanyo ‘Sensor Touch’ television was assembled in Wodonga. Sanyo was one of the international companies that set up business in Wodonga in the 1970s as part of the decentralisation of industry. It continued operation into the 1980s. The Sanyo Australia Pty. Ltd. factory in Wodonga opened in 1974 with 35 staff and production peaked in 1976-1977 when it employed 360 people. In the first ten years 350,000 televisions were assembled from Japanese parts, however by 1984 the number of staff had reduced to 112 and the factory closed in 1987. All Sanyo televisions were then imported from Japan.The Sanyo ‘Sensor Touch’ television has local, state and national significance as it is thought to have been assembled in Sanyo Australia's factory in Wodonga.

The house was built in 1910. The Clota and Sans families were part of a group of families of Spanish (Catalan) background who lived around Surrey Hills, many of whom are buried in Box Hill Cemetery. The house was built for Antonio and Josepha Clota and passed on to their daughter Josephine Sans and her family. Antonio's full name: Antonio Eusebio Miquel CLota (1869-1940; died Surrey Hills) had 3 brothers who came to Australia with him. Louis Clota (1864-1925); Marcus Clota (1866-1940) died Surrey Hills; Eusebio Clota (1869-1919). Their parents remained in Spain. Josephine Clota and Kim Sans had photos taken on the front entrance to the house when they were married on 9 May 1919. The wedding was reported in Punch.Black and white photo of the home of Mr and Mrs Antonio Clota; later the home of their daughter Josephine and son-in-law, Kim Sans and family.

Radio telephones were used to connect people living or working in isolation with other people.This radio phone was used by ambulance officers,working on the Kiewa Hydro Electric Scheme, to communicate with the doctor. The SECV had received an ambulance by April 1940. It had been modified for long and rough trips, departing from usual ambulance designs of the time. Ref. April 1940 SECV magazine. Mrs Beveridge (Skippy) lived and worked with her husband on the High Plains during winter. They had immediate contact with the outside world as they were connected by radio telephone with the Commission's (SECV) Bogong office. Hence, measurements taken of the snowfall and rainfall and observations from the experimental raceline are reported to head office of the Kiewa Hydro electric Scheme at Bogong. Ref. SEC magazine March - April 1948 page 25 and photo of the radio telephone in their home (different to this item) page 26. This radio phone is in a metal case with a separate steel lid attached with two large screws on either side. The front has a cream plastic face with open slits. It has a cover to protect the speaker behind it. There are 3 tuning knobs (volume, muting & channel) and a small red light. The phone cord is coiled and extends from the right hand side with a speaker attached. The speaker is for sending and receiving messages.'Radiophone / MTR 25 161 AG' 'STC' in a rectangle and 'Ser.
