Here we tested the ballista by attempting to launch a shovel handle. The result: We could probably throw the shovel handle farther, but at least the concept works!
Attempting to launch a much lighter projectile. Unfortunately, the launch mechanism failed.
We wind the ballista to full power. The projectile clears the yard.
Our first test firing of the ballista. Probably not a good idea to be testing this indoors!
While we didn't get the spectacular results we were hoping for, we were nonetheless satisfied with our first attempt at building a medieval war machine.
