[edit] Power Transfer Types
There are two main ways of transferring power for a catapult.
[edit] Joint-to-joint
This method provides the most efficient transfer of energy when using powered wheels. By connecting an array of powered wheels on their outside joints to a single main wheel, it can be ensured that the catapult has sufficient torque to launch an object. The catapulting arm can be connected to the outside joints of the main wheel. Due to a physics glitch where the order of connection matters, it is important that you connect the level to the main wheel before you connect the other wheels. Additionally, try to reduce weight on the arm as much as possible by using water rods, which are lighter than their wooden counterparts by a factor of two.
[edit] Chain
A chain is optimal when you are relying on just gravity to propel an object. A chain can either be wrapped around a wheel or just pulled directly.
Chains can be also used with powered wheels when you wish to create a timer. A chain can also be wrapped around two different powered wheels to create an elastic effect, like pulling a sheet tight.
[edit] Catapult Constructions
There are many variations of catapult construction types, but here are the most popular.
[edit] Basic-a-pult
A basic-a-pult is a non-green catapult and is the most basic catapult. It uses a single powered wheel as the core mechanism.
An example of a basic-a-pult in action.
[edit] Power-Pult
A power-pult uses multiple wheels combinined to increase the power of the main throwing wheel. Experience with basic-a-pults is recommended before trying a power-pult.
[edit] Ballista
These work by attaching a chain between two wheels then pulling it straight, shooting objects into the air. There is also a type that uses a chain pulley as in the second example.

[edit] Stick-a-pult
A stick-a-pult is a catapult that does not use any wheels. It uses the same principles as the other pults, simply using weight to force an arm around a pivot which sends the projectile in the required direction. They tend to be much more powerful and piece-effective.
Here is an example of a Stick-a-Pult in action
[edit] Blue-a-pult
A Blue-a-pult is a catapult that only uses blue wheels (usually just one). It's powered by the weight of rods whic make the catapult turn typically 90 degrees. Yortzec's Blue-a-pult Guide can help to strengthen your blue-a-pults and it tells you how to make them more quickly. Blue-a-pults con be modified to push objects rather than throw them.
[edit] Lock-a-pult
Attaching a stick loosely to the center axle of a powered wheel, but holding the wheel steady in a frame from the outer points. The wheel does not spin but it will send the freely attached stick around.
Here is an example of a Lock-a-Pult in action
[edit] Fling-a-pult
Two powered wheels connected by a stick, with a second stick connected to the top of the right-most powered wheel (with clockwise wheels), or the left-most powered wheel (with counter-clockwise wheels). The movement of the powered wheels cause the second stick to swing around after colliding with the other stick, since that is the best way to attempt to continue spinning.
Here is an example of a Fling-a-Pult in action
[edit] Slow-a-pult
A slow-a-pult is like a catapult in the old days except it is very slow.

[edit] Pop-a-pult
A Pop-a-pult is a variation of a Stick-a-pult that uses the form and strength of a triangle to its advantage. It uses more weights than average, but can launch an object higher than other catapults. The catapult works by forcing the triangle to change shape by pushing the top brown side of the triangle below the joint, so the joint snaps up to stop the tension between the two joints on the wood rod, which launches the object upwards with great velocity. The amount of weight used just has to be enough to push the brown side down enough, but the larger the distance from the bottom joint and the stick, the greater the fire power.
[edit] Water Chain-Break Pult
A water chain-break pult is a completely water-based catapult which uses the elasticity of the joints of small rods to send the object across the map. They are inconsistent, and are rarely used. Here are some examples (note they may not work for you):
[edit] New concepts and designs
The Ultra-o-Pult was designed by Dave43. This green catapult offers insanely high speed of the projectile and huge range of throwing.
The Jump-Pult was designed by Enwironzvae. This green squib-like contraption is really cool to watch and difficult to make but it does not work in a lot of situations.
The Pressure-Pult was designed by Corpsegrinder1. The PressurePult is a modification of the green pult that increases the catapult's power.
The Hyper-a-pult was designed by Zelda103. It is the combination of a ultra-o-pult and a water chain break pult which offers x1.5 power of a Ultra-o-pult. This catapult also allows the launching of small objects.
