Leonaro’s concept was novel in that it used a single mast to support the throwing arm, rather than a large framework.
The model kit we offer is a fully functional construction based on his sketches. The arm with the weighted bucket is raised by means of a ratcheting crank.
A fun building activity for everyone, and you can use it to defend your home from tiny invaders. Will fling a small clay ball up to 20 feet.
Suitable for boy and girl
Suitable for ages 14+
