How to build a Ballista

By: Roberto Garabell

A ballista is an ancient kind of crossbow which was utilized in times of warfare by mostly the Greeks - Romans. The ballista works by firing heavy darts or stones to damage the enemy. Persons carry out projects on ancient societies which may require them to feature certain objects from the Greeks and Romans, in such cases the ballista may be needed for a staging. These tools can also be used in screenplays and videos which display ancient times and for some persons this feet may just be to unlock a creative enlightenment by attempting to make something that symbolize antiquity. You can make a ballista by paying for a ballista-making kit but it is much more fulfilling to construct it by yourself from scratch with all the supplies and tools. This will allow you to expand on your resourcefulness as well as reenact an instance of the early days of conflict.

Required Tools:
Hammer
Measuring tape

Required Materials:
Thin rope
Piece of strong nylon
Nails
2 washers
2 hoop hooks
Wooden block 12" high and 12" wide, 24" long; the base
Block of wood 3"x3"x12"
Block of wood 2" x 2" x 24"
2 blocks of wood 2" x 1/4" x 12"
2 - 2" cubes of wood
1 length of wood about the same size as a standard pencil
2 wooden cylinders approximately 2" diameter and 2" long
2 - 2" long poles made of metal
Instructions are as follows:
1. First you have to construct the base section of the ballista. Place it onto the work surface and line up the 3 inch block of wood to the 12 inch border of the base and fasten both pieces of wood together using the nail and hammer.
2. Now position the block so that it is resting with the 3 inch block on the base then use the nail to connect the 2"x24" section of wood to the top middle section of the base.
3. Utilize the hammer and nail to fasten the first 2"x12" portion of wood to the 24 inch piece so that the pieces create a T.
4. Place your 2 cubes of wood between the horizontal wood of the T-shaped design. These pieces should be connected around three inches from where both pieces cross.
5. Place the left over 2"x12" section of wood atop of these cubes. Drive a single nail into this wood, then into the blocks, then into the first 2"x12" piece.
6. Place both wooden cylinders on either side of the horizontal ends of the T shape.
7. Place a washer on both end of the horizontal bar of the T, around 3 inches apart from each side. Nail them in place.
8. Attach a hoop hook between your wooden cube and the wooden cylinder on the inside part of the horizontal bar of the T. then Insert the rope into each hook, and start to wind the rope. When you have entwined it halfway up the length of the rope, twist the pencil-like piece of wood into the rope, then tighten it firmly around the wood.
9. Place the rope into the wood and into the washer. Place your metal pole on top of the opening in the washer so that it lies in a horizontal plane. Knot the ropes and lock them to the poles and slash off the remaining ends of the rope. Connect each of the ends of the nylon or rubber to the pencil-like portion of wood.
Tips and Warnings
* If you are deciding to use the ballista only do it in a well cleared area, and by no means inside. Ensure that there are no persons or creatures near by.
* Experiment with different objects to see which goes the farthest or produces the hardest impact.
