Dad was a tree faller in the Italian alps before migrating to Australia in the early 1950's. He worked in a sawmill for a year before he and his workmate (Charlie) managed to get a contract falling 200ft al karri trees. The started out with Axes and cross cut saws. The had to cut steps an insert boards as steps to get up to a thinner part of the tree like this
Then they would cut the scarf with axes. some of trees were so massive that they had to crawl inside the scarf to complete the cut. Charlie was smaller than dad so he dis that. The the cross cut from behind and jump and run for your life when it fell. It use to take the One and a half days to cut down one tree and buck it into 20-30 ft long lengths
In the mid 50s the Teles Smith arrived and despite only using it 4 hours a day - the rest of the time was sharpening (it had very soft chains) and fiddling with the engine - they were able to cut down 4 trees a day. Because the TS was so heavy the powerhead end could not be lifted to start the scarf with the bar level, Instead the operator at the helper hand end used to lift the outboard end of the bar up high above his head and then pull the end down into the tree. As dad was tall than Charlie he got this job.
In 1959 dad got his first one man saw, a McCulloch with a 42" bar. These were very reliable saws with much better chains and he alone could cut down 8 trees a day. He had two of these saws and used to carry both through the bush along with fuel and oil, and a hessian bag containing steel wedges, chain sloops tools and two axes and a water bottle. This was when dad used to take me out with him but I was only about 6 years old and all I could carry was the fuel and oil. I also made the fire for "Billy Tea" and when I got older rode shotgun (on the top of the diesel fuel tank behind the driver) on the D9 dozer which used to drag the fallen and bucked logs into the truck loading area. My job was to jump off the back of the moving dozer and hook the chain or wire rope around the log. Then run after the dozer towing the log and jump onto the back of the moving tracks so they carried me back up to the level of the fuel tank where I'd jump over onto the fuel tank - OHS nightmares when I think about it.
At this cutting speed and with about 100 other fallers at work in the same are of forest it came down in swathes. After a year of this the local sawmills had enough logs on site for two years worth of milling and all timber falling contracts were cancelled. Dad moved to another town and managed to get back into falling for a few years before he was badly injured in a logging truck accident.
The Teles Smith was sold in 1967 and used as a boat motor. Dad kept the bar until some time in the 70s and got rid of it without telling me.
Years later I went to look for it and was very disappointed to see it had gone.
