Welcome! - Home of the 2012 World Champion Punkin Chunkers!
A Brief IntroductionWelcome to the new-and-improved website for Team Urban Siege. Team Urban Siege is a group of friends that have been building trebuchets since 2006 and competing in the World Championships of Punkin Chunkin since 2008. This website chronicles our team's work and also attempts to provide information on building trebuchets, the weapon of choice for mass destruction in the Medieval Era. Soon there will be design information for arms, axles, slings, frames, counterweights, and a whole lot more. Not only will there be discussion as to how they work, but suggestions as to how to keep your various trebuchet parts from breaking will be here as well. There will even be some free plans for smaller trebuchets to get you started in this fun hobby!
But most of all, this site is dedicated to exhibiting our work. Before 2011, Team Urban Siege was well-known in the hurling community for highly-efficient designs. Medieval Postal Service was a breakthrough machine despite not being designed to WIN. However, that has changed with 2011. Our new machine, NASAW, the North American Sliding Axle Whipper, is a first-of-its-kind, incredibly-efficient and super-long-distance-throwing trebuchet. In just it's first season, on only it's 13th shot EVER, NASAW nearly took out the 7-time World Champion Steve Siegers and his new mammoth machine Yankee Siege II with a shot of 2316.17 feet! In 2012, we managed to beat Yankee Siege II and the rest of the field and take FIRST PLACE at the World Championships of Punkin Chunkin!
2018 Event Schedule
November 2: Dayton Pumpkin Chuck
Team Urban Siege will be competing in the chunk in Dayton, Ohio! Held at the National Air Force Museum, the Dayton Pumpkin Chuck is held on a Friday every fall. We will have NASAW there to compete for the first time since 2016 (in Delaware), and the first time at this event!
November 4: Demo at Ellicottville Distillery
Team Urban Siege will be demoing NASAW at the Ellicottville Distillery! Spend Sunday afternoon with us just 2 days after our appearance at the Dayton, Ohio competition. Watch us launch, learn about our machine, and enjoy some cocktails! This will be at the distillery, located at 5462 Robbins Road, Ellicottville, New York 14731.
SponsorshipTeam Urban Siege would like to thank all of our sponsors, past and present. These include:
Great Lakes Pressed Steel, who made Medieval Postal Service possible by donating the steel and aluminum used, along with allowing us use of the machine shop there and the services of Glen, who did all of the welding for the machine. They were also invaluable in the construction of NASAW, our new competition trebuchet.
Creative Hands Custom Blinds and Window Treatments for wood shop usage, machine storage for most of our collapsible trebuchets, and help with constructing all of our pouches since Jeckyl and Hyde.
Wickham Farms, who was very helpful in finding us ideal test ammunition (pumpkins) at the last minute before the 2010 World Championships, and who has helped us out ever since by growing some particularly hurling-friendly breeds of pumpkins. We send them flying well over 2000 feet!
Thanks also to all others that have donated, time, materials, and even money to the team. A further thanks to those that helped out in other ways. Most of these are listed on the left.
All information found with this site or at other sites linked to from here is used at the sole risk of the user. Team Urban Siege and its members will be in no way responsible for any damage or injuries suffered from the use of this information.
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!!!
This year, after years of talking about it but never managing it due to scheduling issues, we made it to the Dayton Punkin Chunk to compete with NASAW! The event is held annually alongside the runway at the National Museum of the US Air Force.
Yes, Team Urban Siege will be competing in a chunk in 2018! We are working out the final details, but we are planning to attend the Dayton Pumpkin Chuck held on November 2, 2018 in Dayton, Ohio. Yes, this is a Friday event, but as the US Air Force is involved in putting on the event (it is held at the National Museum of the Air Force), this event is always held on a Friday for staffing reasons. We hope to see some of you there cheering for NASAW!
Those that follow us on Facebook likely already saw the news. Owing to a lawsuit recently filed due to the accident at last year's chunk, the landowner that the World Championships of Punkin Chunkin are held on has requested the event to not be held on his property this year. The Association published the following statement on the Punkin Chunkin website:
Yes, the 2017 World Championships of Punkin Chunkin is still happening, on November 3-5 at the same Bridgeville, DE field it has been held on since 2007! Many know that there was an accident with an air cannon near the end of the 2016 event, but despite that the event is moving forward with additional safety precautions. However, Science Channel has pulled their sponsorship, which has left the Association short on funds. The event will still happen in 2017, but its future is in jeopardy without additional sponsors. If you know of a company or individual willing to donate to keep the event going, direct them to the WCPCA Sponsorship Page. Any and all donations are welcome, so feel free to donate yourself at the same link so the Association can continue to give back to the community. The Association is a 501c3 charity, and as such all money raised in excess of the cost of putting the event on is given back to a variety of charitable causes.
It has been a busy fall for Team Urban Siege, but not so much on the hurling front. However, there is more than a little of that news to report. Read on for more:
