Micro Treb is a very small trebuchet built to scale for 25mm fantasy miniatures. It can throw 1/4 inch finishing nails about 30 inches at a low arc. It could probably throw a heavier projectile a bit farther.

Micro treb stands 4 inches tall, with a 7 inch throwing arm. It is built from pine molding trimmings left over from a construction job.

Micro Treb's weight bucket is framed in wood with paper siding. It was then filled with tiny pebbles.

The fulcrum is a bent over paper clip.

A small bit of card-paper forms the base of the machine, providing the skit for the finishing nail to slide on. (The nail is poked through the card stock in this shot to hold position.)

Since Micro Treb was designed for 25mm scale, here it is set up in a scene where the enemy got a little too close.
