When you see the power with which a chainsaw can cut down a tree, it’s not hard to understand why chainsaw operators must respect their tool. A healthy respect for and knowledge of your chainsaw’s limits and hazards will help you effectively mitigate them and keep yourself and others safe. This online training course covers every aspect of chainsaw safety, from pre-operational inspections and setup, to hazards like rotational kick (kickback), and even post operation maintenance and inspection.

https://en.wikipedia.org/wiki/Inductive_discharge_ignition

Inductive discharge ignition systems were developed in the 19th century as a means to ignite the air-fuel mixture in the combustion chamber of internal combustion engines. The first versions were low tension coils, then low-tension and in turn high-tension magnetos, which were offered as a more effective alternative to the older-design hot-tube ignitors that had been utilized earlier on hot tube engines. With the advent of small stationary engines; and with the development of the automobile, engine-driven tractors, and engine-driven trucks; first the magneto and later the distributor-type systems were utilized as part of an efficient and reliable engine ignition system on commercially available motorized equipment. These systems were in widespread use on all cars and trucks through the 1960s. Manufacturers such as Ford, General Motors, Chrysler, Citroen, Mercedes, John Deere, International Harvester, and many others incorporated them into their products. The inductive discharge system is still extensively used today…

Faraday’s Law

The inductive-discharge ignition system operates according to the rules of electromagnetism described by Faraday’s Law of Induction which states that the induction of electromotive force (emf) in any closed circuit is equal to the time rate of change of the magnetic flux through the circuit…

Magnetos

A magneto is one of the electromechanical devices invented for the purpose of ignition with gasoline internal combustion engines. A magneto at its most basic is a simple magnet that moves next to a wire, or sometimes a wire moves next to a magnet. As they move in relation to each other, the changes in direction of magnetic force induce an electric current in the wire. Usually the wire (called a primary wire) is very long, and looped around an iron magnetic core that more or less channels the magnetic field through the loop of wire. As the current flows, the wire loops develop their own magnetic field, which takes a certain amount of energy to form. The magnetic field is a type of potential energy. There is usually some sort of device that opens and closes the circuit called a contact breaker, points or an ignitor…

Some magnetos have a second coil of wire located next to the first, called a secondary coil…

Due to their reliability, magnetos are used as ignition systems on aircraft…

Distributor Ignition Systems

As ignition technology developed, engineers realized that a functional ignition system could be designed that dispensed with the magnets altogether. By applying a current to a primary wire loop wrapped around an iron magnetic core, a magnetic field would be generated in the primary loop without the magnets. This magnetic field would induce a current in an adjacent longer secondary loop of wire. By opening the circuit in the primary loop, the collapsing magnetic field would cause a voltage to be induced in the secondary loop. This high voltage was carried or “distributed” by a distributor to each of the multiple spark plugs in a gasoline car or truck engine.

The most familiar version of this kind of system was invented by Charles F. Kettering in about 1909 and was known by some as the Delco ignition system. Later patent applications to the US Patent Office make reference to the “Kettering ignition system”. This type of ignition system was used on automobiles, trucks, lawn mowers, tractors, chainsaws, and other gasoline-powered machinery with great success for many decades until the development of capacitive-discharge ignition systems.

This short presentation is a brief instructional video on how to collect, filter and purify water by boiling.
Methods shown include the improvised sock filter, millbank bag filter and purifying by boiling.

The video is presented by Gordon Dedman, founder of Bushcraft Survival Australia (BSA). Gordon has travelled extensively and completed numerous Survival and Bushcraft Courses worldwide at schools run by Ray Mears, Dave Canterbury, Lofty Wiseman and Bob Cooper.

Gordon is a former member of the Australian Army 1st Commando Regiment and is presently attached to NORFORCE, an Australian Army Reserve Regional Force surveillance unit.

NORFORCE conducts patrols in the remote areas of Northern Australia, working closely with Aboriginal communities.
