Bump

Hey /sci/, do you happen to know any cheap chinese wholesale sites where they sell electronic components (capacitors, resistors, transistors...)?
Like dealextreme, but for electronic parts.

So it seems.
Onager/mangonel/scorpion is more or less the same thing, where one has a sling and the other doesn't. Pretty sure the scorpion is (one of) the name(s) of the sling version, since it has a pin on the arm which releases the sling, which makes the arm look kind of like the stinger of a scorpion.

The large crossbow you're referring too is the ballista, which is also powered by torsion by the way (see image, not ours this time, lol). We also build that one, but overdid it (like we usually do) and haven't figured out a way to actually 'load' it. I don't know the correct word for it, the act of bringing the arms backwards so it can actually be fired.
Anyway, the torsion on it, using just standard nylon rope, is so high we can't even get the arms halfway down.
