This is part of a crosscut saw raker/jointer/guage set used to bend the tip of each cutter tooth for cross cut logging saws. The logging saws used in the early 1900's for the clearing of forests required constant sharpening of their "cutting teeth". The logging of forested areas during these times was very much a "hands on" method of either one or two men by the use of saw or hand axe. This item was used by the surveyors commissioned by The S.E.C. Victoria Kiewa Hydro Electricity Scheme project mapping the relevant Alpine region. Chain saws, chain and ball(clearing) and bulldozing methods came in the mid 1900's.This particular saw sharpening method was used by surveyors laying down boundaries for the S.E.C. Victoria Hydro Electricity Scheme (1920's). This item was given to a local Kiewa Valley lad who accompanied the initial surveyors. The lad was responsible for the tendering and feeding of the surveyors "pack horses". Surveys work during this period and in these dense mountainous terrain of the Victorian Alps was both exhausting and hazardous. Overnight accommodation at various log cabins was not always possible and swag/tent alternative was the "fall back".This cast iron Spring Setting tool has a main body of angle iron contours with one end tappered into a flat circular extension with a slit (3/32" wide) running from the top to nearly the centre(15mm). This slit is to allow the bending of each "cutter tooth" of the cross cut saw. The "bottom of this slit has a semi circular ending. Protruding from one side of the bar body, and close to the "slit" is a tounge like extension (wedge) to fasten the spring set tool into a tree stump. See KVHS 0090 (A) for its Raker/Jointer saw sharpening guage set partner. Also see KVHS 0090 (C) for the associated wrench.

This butter mould/pat may have been manufactured post 1967(year post codes appeared in Australia) however the post code was only stamped on after it was machined. This type of butter mould was used by rural families to fashion home/farm made butter. This period was in most rural regions a time of self sufficiency where any domestic type implement which could be fashioned by the family would be crafted with skill. Shopping for goods required catalogues from stores located in major rural towns and cities and involved lengthy waiting times. Travelling to and from these specialised stores was not pleasant due to the relatively poor quality of the roads and the lengthy times taken. The small general stores in the Kiewa Valley could not cater for all the needs of the valley. The 1960's was a time when facilities especially goods and services started to improve drastically. The S.E.C. of Victoria with its Kiewa Hydro Electricity Scheme provided not only an improvement of facilities in the valley but also a increase in the population. This increase resulted in a greater demand for local produce. This item is one of many domestic food processing implements used by Kiewa Valley households in the mid 1900s, whether on the farm or in the small towns and hamlets. Self sufficiency was the key to survival during these early times. Where ever possible supplies from within the valley were preferred to that brought in by travelling salesmen or traders. This butter mould and butter pat was commonly used to fashion "home" made butter throughout the valley and in some cases supplied to "outside" regional towns. Although this method of production was phased out by better access to goods from nearby cities the revival of the good organic home grown produce in the 1980s saw a greater demand of this type of farm based produce.This well crafted circular wooden butter mould could also be used as a butter pat.The handle in the middle of the mould was not added after the crafting but has been fashioned from the initial block of wood when the bowl was crafted. The bowl structure has a rim around the edge.The top of the handle has an ink stamp "T. & W. Dav" on the top line and "Tawonga 3697" underneath.domestic food preparation, wooden butter pat, butter mould circular, dairy industry

The State Electricity Commission was established in 1920 with the development of the Yallourn Power Station and brown coal was used for 90% of Victoria’s electricity supplies. In the 1990s the Commission was abolished and electricity companies were privatized. In Warrnambool electricity was officially connected to the city in 1924. This plate is one taken from a Warrnambool power station. One power station in Warrnambool today being located in Botanic Road.This plate is of some interest as a reminder of the times when the State Electricity Commission controlled power supplies in Victoria.This is a small rectangular metal plate with four holes at each corner for attachment to a Warrnambool Power Station.

The fire hose reel was purchased by the Fire Ladies' Auxiliary for the Mt Beauty S.E.C. Fire Brigade in the late 1950's for over 1000 pounds. Initially they competed with Bogong fire brigade as both were 'Industry' Fire brigades - both owned by the State Electricity Commission. Competition was at 2 levels - north east Victoria and state competitions involving rural and urban brigades with a difference in the equipment. Mt Beauty was/is an urban brigade whereas Tawonga is a rural brigade. Competition involved members to improve their skill, keep fit and was a very social occasion. After the Shire took over Mt Beauty township in 1961, the Fire Brigade ran by itself but soon became affiliated with the C.F.A. because of insurance and legal liability e.g.. enabling them to stop traffic or wreck buildings if required. The CFA were not happy with the Mt Beauty truck so a new one was obtained while the old one went to Bogong. Competitions gradually ceased as it was a young man's sport and young members had prior commitments. The reel was donated to the KVHS in the mid 1980's as it failed to be sold as it competed with new, cheaper, aluminium reels. The practice strip was located beside the fire station in Lakeside Avenue. This fire hose reel was used by the Mt Beauty Fire Brigade for demonstrations at competitions during the 1950's and 1960's. The Mt Beauty Fire Brigade Team won the competition in 1966 at Wangaratta. The score was close against the home team and was decided on a play off. The team benefitted by the man who wound the hose on allowing it to end up at the easiest height to handle when full of water and very heavy.The Mt Beauty Fire Brigade was an 'industry' fire brigade belonging to the State Electricity Commission of Victoria from the 1940's. It became a member of the Country Fire Authority in the early 1960's. During the 1950's and early 1960's members would compete with other local fire brigades in competitions against other brigades in the north east of Victoria using skills such as unwinding the hose off the reel and turning on the water in record time. The Mt Beauty Fire Brigade continues today as an urban fire brigade affiliated with the CFA.Varnished wooden cart reinforced by painted red steel frame.

The Tawonga District Hospital opened in the early 1950's in the Kiewa Valley to treat local patients from Mt Beauty and the residents of the KIewa Valley. The State Electricity Commission of Victoria assisted with the building of the hospital as the population of Mt Beauty increased with the S.E.C. workers and their families during the construction of the Kiewa Hydro Electric Scheme. The Tawonga Hospital was later relocated to Mt Beauty. All the enamel equipment was eventually replaced with stainless steel.This grey enamel basin is large with a royal blue lip.

Differing gauges of transmission line was/is used in the Kiewa Hydro Electric Scheme. Some carried 330KV, 220KV, 66KV (Mount Beauty to Bright) and (Clover to Mount Beauty) and 22KV. All the cables have a core of steel for strength and an aluminium outer layer for transmission. Examples include 66KV copper cable, copper earth wire from the towers, copper cable found along the aqueducts for telemetering and copper earth wire. The 24 Volt Communication cables were/are used for linking different sites on remote SEC equipment.The State Electricity Commission of Victoria constructed the Kiewa Hydro Electric Scheme during the late 1930's to 1960's. A wooden board with samples of differing gauges of transmission cables used for the transmission of power and 24 volt communication cables used for communication linking different sites on remote S.E.C. equipment. The cables No.s 1 to 9 have a core of steel for strength and an aluminium outer layer for transmission. The copper cables No.s 10 - 14 are used for earthing and are in the ground as copper doesn't rust or corrode (steel does). Copper is three times heavier (dense) than aluminium. Each of the outside aluminium wires are wound in the opposite direction so that when the cable is stretched under load, they tighten.state electricity commission of victoria. kiewa hydro electric scheme. cable. communication. transmission. telemetering. power. electricity.
