Description
A spear thrower is a simple tool that allows the user to throw a spear further than by hand alone. It is a small length of wood with a hook in the end that fits into a notch in the back of the spear. The extra power and distance gained by the thrower is due to the extra leverage it gives.
I cut a small branch with a minor branch coming off the side. I shaped the minor branch into a spur to fit into the end of the spear. The thrower was about 65 cm long.
For the spear, I cut a thin sapling approximately 2 m long and about 1.5 cm thick. I carved a cup in the end of the spear for the spur to fit into. Then I bound the back of the spear with bark fiber to prevent the wood from splitting. The head of the spear was simply charred in the fire and scrapped against a rock to sharpen it (during practice the head regularly breaks so only a sharpened tip is used to save work).
To use the spear thrower, the spur of the thrower is inserted into the cup of the spear. The spear and thrower are held at about shoulder height. The thrower is quickly flicked forward and the spear propelled towards the target. As the spear leaves the thrower it bends slightly storing energy until it jumps of the spur. During flight, the flexible spear wobbles and oscillates paradoxically giving the spear some stability in flight.
The throws in the video show what can be done in one afternoon of practice (my arm got sore and I wanted to start on other projects). I hit the target a few times at a distance 15 m. It is more powerful than a spear thrown by hand alone but is difficult to learn. The spear I made could have been a fraction lighter and so would have greater speed. Another improvement would be to add flights to the spear so it would be more accurate and fly straighter (like an atlatl).
The extra energy gained from a Woomera"s (Australian spear thrower) use has been calculated as 4 times that of compound bow (Wikipedia). It"s easy to make (this took less than a day) but requires lots of training to become accurate.

I've repeatedly been obsessed on the atlatl mechanism.I'm no longer obvious if I truly comprise sufficient persistence to learn the tactics, alongside with having unpleasant rotator cuffs in both shoulder.
It's like an damaged-down Demolition Ranch

Dilapidated Skills: Spear Thrower28 811 607 просмотров 8 окт. 2016 г. A spear thrower is a easy instrument that enables the client to throw a spear extra than by hand by myself. It’s a dinky measurement of wood with a hook in the discontinue that suits accurate into a notch in the again of the spear. The additional energy and distance won by the thrower is as a result of the additional leverage it affords.I scale again a dinky department with a minor department coming off the side. I formed the minor department accurate into a spur to fit into the discontinue of the spear. The thrower turned into about 65 cm long.For the spear, I scale again a skinny sapling roughly 2 m long and about 1.5 cm thick. I carved a cup in the discontinue of the spear for the spur to fit into. Then I drag the again of the spear with bark fiber to prevent the wood from splitting. The top of the spear turned into simply charred in the fire and scrapped in opposition to a rock to sharpen it (in some unspecified time in the future of dispute the head generally breaks so handiest a sharpened tip is extinct to place work).To exhaust the spear thrower, the spur of the thrower is inserted into the cup of the spear. The spear and thrower are held at about shoulder height. The thrower is readily flicked forward and the spear propelled towards the target. Because the spear leaves the thrower it bends barely storing energy except it jumps of the spur. In some unspecified time in the future of flight, the versatile spear wobbles and oscillates paradoxically giving the spear some stability in flight.The throws in the video expose what may perhaps perhaps perhaps be carried out in a single afternoon of dispute (my arm bought sore and I needed to begin up on diversified tasks). I hit the target just a few times at a distance 15 m. It’s extra extremely effective than a spear thrown by hand by myself nonetheless is essential to learn. The spear I made may perhaps perhaps perhaps had been a part lighter and so would comprise elevated velocity. Another boost may perhaps perhaps perhaps presumably be to add flights to the spear so it would be extra steady and skim straighter (like an atlatl). The additional energy won from a Woomera's (Australian spear thrower) exhaust has been calculated as 4 times that of compound bow (Wikipedia). It's straightforward to plan (this took lower than a day) nonetheless requires a complete bunch practising to turned into steady.Wordpress: https://primitivetechnology.wordpress…Patreon internet page: https://www.patreon.com/consumer?u=294588…I truly have not any face e-book internet page, instagram, twitter and masses others.
