The Arborist’s Wood Chipper

Commercial arborists specialise in clearing trees and scrub very efficiently and safely, leaving the land behind ready for whatever new purpose it has. Amongst the many highly specialised and powerful machines that the arborist has in their toolbox, the industrial strength wood chipper has to be one of the most impressive.

This machine is powered by its own diesel engine, and is capable of completely demolishing a 10 or 15 metre log of around a foot in diameter in just a few seconds. These machines are totally portable, and the resulting wood chips are fired like bullets into the back of the covered truck. To the casual Observer the wood chipper appears as a scary Beast, and this is reinforced by the fact that the machine is only loaded by the digger, and the wood chiiper machine operator stands back at least 20 metres.

The diesel motor driving the machine runs at high speed, and it’s main task is to power up a massive flywheel that will deliver power to the chopping/grinding wheels. The machine will literally suck in the logs and squirt out the wood chips, and for reasonable diameter logs of just a few inches the machine will do this in one continuous motion. Larger logs up to a foot in diameter will cause the machine to stop and start frequently, but the reason for this is that the machine is waiting for the diesel motor to spin the flywheel back up again. It is the flywheel that provides the massive horsepower that means that the machine does not stall.

With a skilled digger grabber operator feeding the machine continually with massive branches and tree trunks, the truck can be filled with wood chips in a matter of minutes, and while it is away emptying the load the digger driver can reposition other logs and scrub so that it can feed this into the wood chipper once it returns. The best arborist Hamilton has ever seen would do well to use this impressive tool.

The wood chipper is incredibly impressive to the casual observer who may have used a garden shredder at some stage. The garden Shredder is very easy to stall with only a small handful of twigs and leaves, and next to a fully fledged wood chipper the garden shredder looks like a paper dart compared to a Boeing 747.

Feeding the wood chipper with the digger and grabber is a very safe way to operate, but it can come unstuck if the digger driver and the truck driver are not on their toes and carefully observing every load. It has been known for the digger to accidentally pick up a large object like a piece of railway line, and this can basically destroy the wood chipper if it is fed into it, causing thousands of dollars of damage in a fraction of a second.

House Building Apprenticeship in New Zealand


There is a massive shortage of new homes in New Zealand and a corresponding very high demand for builders. Builders need helpers both unskilled and skilled, and commonly builders will take on at least one apprentice.

An apprenticeship is a very good pathway to a lucrative and enjoyable career you’re a smart and hardworking young builder. The apprenticeship means that the young builder gets good on the job training and experience, plus he or she gets to go to classes to learn about good building practice and modern techniques and from there they can get fully qualified.

A good building apprentice may take 3 to 5 years to come out of your apprenticeship, but they were generally have been fully employed and paid during this period, and they will come out with a qualification that means they can go into business on their own if they want to. This is very different two young people who have chosen to go to university, because not only will they have not been paid while over at university, they will generally have accumulated a large debt which will take them sometimes decades to pay off.

A building apprentice can come out of his or her apprenticeship by their mid twenties, and at that stage not only be debt free but they can also have accumulated enough money to make a deposit on a new house or to buy a nice car etc. They are also allowed to build your own home in their spare time, and many building apprentices have this as their major financial goal. This is because they can build the house for vastly less cost then for the average homeowner as they will absorb all their own labour costs plus they will get the full trade discount on all of the materials. If they have chosen the house location and design well, then they will see a very significant capital gain over a short time frame, and builders commonly sell their first time at a very significant profit. If they are smart then they will pull this profit into the deposit for the next house, which will generally be much bigger and more expensive, and could be there long term family home or could be used to sell off for a much larger profit.

In fact legally registered builders are only allowed to build two homes for their own use in any 10-year period, but if they are smart they can accumulate a few hundred thousand dollars over this period, and a million or more dollars over their building career.

A building apprenticeship pathway to an outdoors and indoors lifestyle, is building a new house requires laying foundations, sitting up the frame, installing the roof and the cladding and all the window and door Joinery before installing the lining and finishing off the house. It is a very varied occupation that is highly skilled and requires a great deal of knowledge about good building practice, but it can also be very lucrative for the Builder that knows how to play the game.
