Building the new Machine





Long time, no news. Well, construction is well underway on our new trebuchet for the World Championships this fall. Our application has been accepted, so we will in fact have a spot this year and fully intend to be there competing. Details of exactly what we are doing are being withheld until October 31, when the competition begins. We are not intending to enter just to enter, we intend to be very competitive among all those not aiming for 2000 feet (currently Yankee Siege, Pumpkin Hammer, and Merlin, perhaps some unknown will show up as well to make it interesting).

Designing is still not fully complete, but the frame is fully designed and actually 90% of all the components are cut and sub-assemblies assembled. Seeing as how we have no trailer to mount to, the machine can come down to a pile of lumber that will have to be bolted together with quite a few bolts. Arm and counterweight and such is almost designed, some simulations are needed to ensure they won't break, then we will order and make that stuff. We hope to get the first throws off sometime in early-to-mid September.

Use "common sense" when operating trebuchets and catapults. Even little ones can be dangerous. Do not place anything you are not willing to lose in the plane of the arm rotation (this includes yourself, body parts, car windshields, cameras, etc). These catapults and trebuchets are capable of throwing just as far backwards as forwards, and the use of a backstop of some sort is recommended, though the use of one does not make the region behind it safe.

Also, just because the throw got away safely downrange does not mean the end of the danger. The arm is likely still swinging wildly along with the counterweight, and there is a sling whipping around. One thing many people fail to take into account is this sling; some people put a metal ring on the slip end of the sling and this ring can HURT when whipping around!

Have fun hurling, but please KEEP IT SAFE!!!
