Could I build a giant crossbow? Answered

using a section of a leaf spring from a truck, put it on a substantial piece of lumber, pull it back with an electric winch and remotely fire broomstick sized bolts

You can but I would have to agree with the others. I know of this weird crossbow that's like a bazooka of the medieval times. It's carried by two people and fires fat bolts (they kinda' look like they contain explosives or something).

i think a better question is: why WOULDN'T you want to? =P<br /> <br /> there are a few blueprints on the web for a ballista. if you search hard enough you'll find a good one that has clear instructions.<br />

It is possible. The most difficult part would probably be a spring that is made correctly, and the trigger. Maybe you could instead of a crossbow, build a ballista or scorpion, like those in these links:

I'm going to go with 'only if you can find a trigger that will work'. A truck spring is going to deflect what, 3 inches under a ton (2000+ pounds) of weight? Can you make a trigger that can handle the weight and quickly and reliably release? Without it trying to rip your hand off when it 'pops' off the string?
