Here is a big trebuchet made by Chris. Now this is the perfect outdoorsman trebuchet! We can call it a survivalist treb!

Here is what Chris has to say about it: The new range with a golf ball is a staggering 425ft, the old range was 250-350ft, and that was with a rock, the trebuchet stands 14ft tall, and 6ft wide at the bottom.

He also did a lot of experimenting with the sling length and he came up with the perfect length. It is 2/3rds the length of the swing arm.

A big thanks go out to Chris for sharing this terrific trebuchet with us.

Here is an update on the performance of this Treb (from Chris)

Hi Will, I just got 500ft with a golf ball...! the counterweight was at 200lb and I got that weight by getting a 5 gallon bucket and filling it with snow and ice, my goal? 600ft.!

Here are the Counterweights:

The Miniature Trebuchet by Timberkits

The trebuchet was the ultimate artillery weapon of the medieval period and early renaissance. A large and unwieldy weapon, it was typically built on-site during battle, and tuned to lob great weights - such as the carcasses of rotting horses and pots of burning pitch, over the castle walls and onto its inhabitants. Precision carved by computer controlled machinery for guaranteed fit and accurate joinery. The detailed instructions include loads of photos of each step of the construction process, tuning tips and safety notes. Included in the kit are four wooden projectiles, all the necessary components for the sling, trigger, and counterweight bucket as well as all the parts for the kit. The only thing you'll need to supply are 88 pennies for counterweight and a few simple tools - Scissors, a ruler, a utility knife, wood glue and a few rubber bands to hold the pieces together while the glue dries.
