Using the Logosol Timberjigg in Australia

  I was lucky enough to get a Logosol Timberjigg for my birthday two years ago. Last year I got two ripping chains and bars (50cm and 63cm). Here’s what I’ve learnt so far. Summary It’s fun and rewarding. For a few hours of work you can get a lot of valuable timber from what might otherwise have been burnt, chipped or left to rot. This is hot, heavy work. It’s also dangerous and dirty. You face ends up close to the chainsaw engine which is very noisy and you get to breath a fair amount of 2 stroke smoke and saw dust. A face mask is a good idea. Helmet, earmuffs, gloves, steel capped boots and chaps are essential. It’s ideal for small scale jobs e.g. salvage from awkward spots The Timberjigg is a, fast, flexible, low cost, low storage space, low learning curve way to make timber from wood. If you have more than a few trees to do per year and you can get access, hire a mobile milelr. It’s faster and there’s less waste. Gear You need a big chainsaw. I have a Stihl 460 Magum.

Queensland’s Fraser Island was inscribed on the World Heritage List in 1992 —  eight years before Sarawak ‘s Gunung Mulu National Park.  The fight to have Fraser Island World Heritage listed though started in 1974 and was a major public debate for almost two decades prior to its recognition.  It is therefore surprising that once it was listed the Queensland Government has allowed it to become so degraded that some people are now arguing that it needs to be placed on the World Heritage in Danger List. It isn’t that Fraser Island lacks the values that warranted its World Heritage listing in the first place.  It is just that the management values for Fraser Island are pre-occupied with recreation Management to the neglect of the protection of its World Heritage values. Photos tell the story On Fraser Island 4WD recreational vehicles rule all policy decisions even though environmental studies have conclusively shown the impact of the 4WDs in compacting sand in the substrate and thus accelerating water erosion.  The mobilization of sand as a result of this means that over a three year period more than a million tones of sand has been mobilized and sluiced down the slopes.  That means over a tonne of sand it relocated for every visitor to Fraser Island! Some roads are now scoured down to a depth of 4 metres and they continue...
