Mini Mayhem!

Mini versions of our original models. Easy to assemble!

Designed and made in the USA for better quality, better performance!

The Greek Ballista and Roman Onager are the granddaddies of all modern field artillery. These models are both fully functional and really work!

The Ballista was an engine of war invented by the Greeks in 800 BCE, and later adopted by the early Romans into the Onager. These machines were constructed of different sizes for the various purposes of siege and field warfare. The largest ones could throw projectiles weighing up to fifty pounds as far as 400 yards!

Each model uses skeins of twisted rope for power. When not shooting bolts, this model is a great addition to your bookshelf or desktop (and it can help to keep those pesky barbarians out of your cubicle!)

Easily assembled in one evening (plus glue drying time). Everything you need is included except for glue and a few simple tools like scissors, sandpaper, a file (a utility knife would be helpful too) some small clamps or rubber bands, and about two to three hours of your time from start to finish.

Features include:
  • Precision cut by computer.
    All parts guaranteed to fit properly!
  • Authentic trigger mechanism
  • True skein torsion power- not a wimpy spring
  • Actual range from 10 to 30 feet!

    The instructions are highly detailed and complete with photos and diagrams. Some light sanding (or trimming with scissors) may be necessary to smooth any rough edges.

    We've put a lot of time and effort into making this kit as easy and complete as possible. It's a fun way to learn about history and engineering!

  • Tools required:
    Scissors, Glue, Ruler, and a utility knife. Sandpaper is optional.

    Assembly time:
    For a Master carpenter doing a sloppy job: about 30 minutes.
    A person with no kit building experience being extremely meticulous: about 2-3 hours.
    The model in these photos was built by Ron Toms in under one hour.

    So, why do my kids
    need this stuff?

    Seriously, get some toys, go outside and play. It's good for you. Spend some quality time with your kids, your buddies or just get away from the TV and computer long enough for a good dose of sunshine.

    Learn a new skill. Get some exercise. Make someone happy. Make yourself happy. Set-up some cans and knock them down, just to see if you can.

    Teach your kids something about safety, posture, focus and concentration. It's easy if they have something fun to do while they're learning it.

    The science of Physics was founded on the principles of ballistic motion. What better way to develop an interest in physics than to play with ballistic toys? And you know where that leads... First, physics, then math, engineering and economics. Next thing you know, he'll be studying medicine with plans to become a ridiculously high paid sports doctor with a keen knack for investing, all because someone bought him a projectile shooting toy gun as a kid. How's that for a reason?

    Here's an even better reason- kids like to play with their parents and they like to compete. Do some target practice with your kids in the backyard. It's far better than watching re-runs of some lame TV show or turning into a video game zombie! Parents and kids need to interact. It's our goal to provide the toys that make it easy. We're doing our part, now you need to do yours.

    So, one more time, get some toys and go outside and play!
