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

Bob (Herman) Hymans (a former member of the Royal Netherlands Navy) was born in Bloemendaal, Holland on 30th September 1922. During World War II he fought against the Japanese in the Dutch East Indies (now Indonesia) and was imprisoned in Changi and on the Burma Railway. After gaining qualifications as a Ski Instructor, Bob arrived in Falls Creek in July 1950. Working as an Instructor and Supervisor at Bogong Lodge, Bob decided his future was in accommodation. He was successful in negotiating an indenture for land from the State Electricity Commission (SEC). It took Bob two years to build his Grand Coeur Chalet but, tragically, it was burned down in August 1961. Bob also built the first Chairlift in Australia. This was a single chairlift and the structure was built from wooden electricity poles. He was constantly full of new ideas and proposals for the village. Bob Hymans die on 7th July 2007. This Collection of documents and letters tells the story of Bob's endeavours to develop Falls Creek into the ski village it is today.This item is significant because it documents actions taken by the Falls Creek Tourist Area Management Committee in their role overseeing the Tourist Area.The Committee of Management forwarded a letter from the SEC outlining the requirements for driving in the Falls Creek area.

Permits could be obtained on demand at the Commission's Information Centre, from the Commission's Head Office in Melbourne.falls creek tourist area management committee, falls creek administration, state electricity commission

In 1940 Field Headquarters for the Kiewa Scheme were established at Bogong with office, workshop facilities and accommodation for workmen, staff and some families constructed. (There had been a 'tent camp' on this site in 1939 but was destroyed by bushfires) Construction of accommodation continued until 1947. A total of 40 houses plus a hostel for single staff, post office, police station, medical centre and primary school all with water and sewerage and electricity supply. The staff hostel was known as Kiewa House and is now occupied by the Education Department. Lake Guy was named after Mr. L.T. Guy who was the Resident Engineer in charge of construction work and associated activities on the Kiewa area. He held this position from 1939 to November 1946 when he was transferred to Head Office. The Bogong Township was developed firstly as an accommodation centre (base camp) for construction workers employed under the Kiewa Hydroelectric Scheme. Due to the influx of European workers into the Township the beautification of the immediate surrounds (gardens etc.) had a distinct European flavour. This environment has been very beneficial for tourism in later years. At the completion of the scheme, in the 1960's, the village was opened to public/tourism use. Strict environmental control has not allowed for any extensive redevelopment in tourist accommodation and basically restricted it to the accommodation initially built for the construction workers. Activities such a bike riding, snow skiing, restricted horse riding and bush walking on the Alpine plains and mountains are now a viable part of the Kiewa Valley Tourist Industry. The lake is one of the many water storage reservoirs used to supply the power stations their main power to run the huge turbines generating the final product, electricityBlack and white photo of Bogong Village.
