Siege crossbow

im currently building a siege bow out of knex and have the main parts ready but have still got to do a base to keep it from bending around. also, any ideas for triggers?

Search for crossbow or ballista on Wikipedia or Google. I'm sure there will be diagrams provided.

if you look on mine you will see that it has a barrel and a simple trigger that blocks the path of the ram a i added a hopper thats why its called the rapid fire cross bow. i hope this was helpful to you.
