X-treme Onager

New low price!


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


Now made from top-quality solid oak non-toxic, formaldehyde-free plywood for a more
dimensionally stable, stronger, and less expensive model than if made from natural wood.

Modeled after the Roman Onager, this torsion-based machine can hurl golf balls and tennis balls over 50
feet!



This modern design for an Onager uses the exact same principles as the ancient Roman war machines. It
is capable of hurling small stones, golf balls, walnuts, eggs, tennis balls and even potatoes from 20 feet
to more than 50 feet! It all depends on how much power you build into it and the weight of your
projectiles. Precision crafted of high quality hard wood, the kit contains everything you need to build a
working model in one evening.*

The advantages of this new design are:
  • Double cross-grain frame for added strength.
  • Higher skein and arm rest allows for longer slings.
  • The arm can travel farther, well beyond the vertical limit of a traditional onager.
  • A soft arm arrestor eliminates hard impacts between the arm and the frame.


The ONAGER (also called a Mangonel) uses a bundle of twisted ropes (called a skein) for real torsion
power. This torsion engine is so powerful, a full-sized machine can hurl a bowling ball almost 1/4 of a
mile!

The finished model stands 17" long, 14" high and 12" wide. The kit is precision crafted from top-quality
engineered hardwood plywood and includes a working winch and real leather sling-pouch.

The detailed instructions are complete with diagrams, photos and tuning tips so you can get the most out
of this fun project. All parts are pre-cut, pre-drilled and can be assembled to a finished model in one
evening.

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!


* Golf ball and tennis ball missiles are not included.
* Can throw over 50 feet when properly constructed and tuned. Your performance may vary.

WARNING! This is a representative model of a real ancient military weapon. It contains a fast moving arm
that can cause injury if you make contact when firing. Use only under adult supervision.



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

Assembly time:
For a Master carpenter doing a sloppy job: about 2 hours.

Notes:
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!
