The Desktop Onager

Now made in a mini version!

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

The Mighty Roman ONAGER, Now available in a desktop model. This display-quality model really works and can shoot missiles up to twenty feet.

This awesome little machine is the perfect desktop item to enforce the peace in your cubicle or dorm room. It really works!

This all wood and twine machine has no metal parts! Find out how the ancients were able to use nothing but wood and ropes to build machines that could hurl heavy stones great distances. These machines were the predecessors of cannons and modern artillery!

Measuring nine inches long, six inches tall and using the mighty torsion skein for power, this beast hurls wooden balls (included) up to twenty feet across the room. Food fight? Load it up with olives, marshmallows, maraschino cherries... the choices are endless!

Simple and easy to build. This kit includes everything you need except for glue and a few simple tools like scissors, sandpaper, a file (a utility knife would be helpful too) and about two or three hours of your time from start to finish. It's a far better use of your time than watching TV, and you'll have a really cool desk ornament when you're done. And don't forget, it not only looks cool- but unlike those other little desktop catapults we've collected, this one really works! (It works well too.)

Features include:

    -- Precision cut from high quality hardwood
    -- Authentic leather padded strike bar
    -- True skein torsion power- not a wimpy spring
    -- Range from 10 to 20 feet or more!

What you get:
The kit includes seventeen wooden parts, precision cut from high-quality furniture grade white hardwood. One hardware bag containing twine, trigger, wooden pegs and ammo, and assembly instructions.
The natural white wood can be stained any color

The instructions are highly detailed and complete with full-color photos and historical notes. This kit can be assembled to a finished model in two to three hours, plus glue-drying time. Some light sanding may be required 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!

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!
