Desktop Trebuchet (2000)

Years before I made my 12' tall trebuchet, I experimented with a desktop sized one made from popsicle sticks. I managed to find some plans on the internet, and simply built it with a few modifications. The trebuchet is made from popsicle sticks, and ended up 7 1/4" tall, 5 3/4" long, and 6 3/4" wide.

The throwing arm is 4 5/8" long and the counterweight arm is 1 1/4" long. I used three lead weights from a salvaged throw net for the counterweight. They are tied together and act as a hinged counterweight, which increases the efficiency of the trebuchet.

The pin for the sling is made from stainless steel tie wire and is easy to adjust to tune the machine. I designed a trigger that would hold the arm down to assist in loading. It works fairly well, although it can knock the sling off the pin if you're not careful.

Over all, it's not terribly efficient, but it is fun to throw cat treats around the room for my cat to chase. It throws them somewhere around 10-15 feet.
