Build A Catapult... or a Ballista!

THERE WILL BE A BRAINSTORM MEETING THIS TUESDAY. EVERYONE WHO INTENDS ON DOING THIS EVENT**//__MUST__//** COME. -Matteo

Since Leah and Matteo didn't finish it, I figured I could. Now we'll know if this design will work next year.



It currently is not completed of fully functional. However, it'll fire a tennis ball about 5 meters. Demostration at Sunday meeting?

Monica intends to complete the ballista and test it, keeping in mind that she may be kicked off by Matteo and Leah.

Leah is not going to be around to test it over the summer, but Matteo and Monica and anyone else helping WILL keep this page/me updated or face the consequences. :D

Ballista construction has been completed. Any one feel like testing?

if you ask me, we should consider what we have now a prototype. i would like to build another, depending on resources, with what we know about this one. issues: cutting the notch in the pipe-i actually found a jigsaw in my basement that i didnt know we had. while probably one of the more dangerous things, it might work pretty well to make a nice, clean cut. angle-i used to have a formula that would determine the angle if we moved the bar through the holes diagonally(made during high dive, of course :P). ill try to find it adjustment-the best thing to be able to do would be to have the ability to adjust the angle, as well as the power. if anyone has suggestions, post them. stability-we need to add reinforcement to the particle board. other than that, i think were good! -Matteo
