Which is a good pun if you know any Latin. For others this is Onager-in-a-Can.
A slot together table-top fully functional onager. We all know that cubicle wars are hilarious, but not all of us can afford those twin over chrome plated fox tailed ossiclating widget grublet flash missile launchers that are all the rage with the computing nerd warriors. So why not get anciebnt on their ass with this fully portable system! Yes you can take Onager-in-a-Can with you anywhere it its handy plastic box your tiny catapult will be safe from crushing and can be assembled in minutes.
That geek from accounting will never know what hit him! (A small plastic bead in fact)
Eassily mistaken for a lunch item the Onager-in-a-Can belnds in on your desk top…
When opened we see all the components and ammunition simply waiting to be assembled.
The parts are laid out and the rubber bands added to the torsion frame.
The throwing arm is inserted with the bands wound up.
The main frame s then slotted together…
and finally the crash bars are added.
Your Onager-in-a-Can is now ready to go.
Onager-in-a-Can is made from 3mm (1/8) blasa wood using less than half a sheet. You can build one using the plan that is available from the 22AD Artillery blog for a compelled $1 donation to the research fund. The plan is full size so you can glue it directly to the wood for cutting and comes with photo instructions. there is an additional experimentation and history sheet included with the PDF file so its ideal for teaching some history and physics to the kids.
Current range is about 10 foot and if you happen to have a model making bandsaw like me then you can make one out of some hard wood and get much more range if you so desire. Origionally I had planned to make something that glued together but it turned out that the model worlks well just being slotted together meaning you’ll be able to change rubber bands without breaking it apart.
