Golf balls work well because they are lightweight, have little air resistance, and are designed to fly far. If anybody is having trouble with the projectile, try Golf Balls.

The release mechanism is just a single chain link tied to the end of the sling rope, which slides on a metal pin (about 1/4" thick) that I bent and attached to the end of the throwing arm. @Jonathan – if you’re talking about the axle that the throwing arm rotates around, then I screwed two 2″x4″ blocks on either side of the arm, and put two 3/8″ lag bolts into the blocks from either side.

Thanks. What did you use as the axle at the top of the throwing arm, and how does your release mechanism work?

Don't aim across Deer Creek or you might hit my brother. Loved the post re: MIT class of '83. Your hair was the same in high school IIRC. Ha. Don’t aim across Deer Creek or you might hit my brother.

Now that definitely would have impressed my wife. As an example of a big trebuchet, see http://www.youtube.com/watch?v=UEho24rgryE for car throwing. Now that definitely would have impressed my wife.
