Welcome! - Home of the 2012 World Champion Punkin Chunkers!


A Brief Introduction

Welcome 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!

2017 Event Schedule
Sept. 23 :
As in years past, Team Urban Siege will be demoing a trebuchet at the Wickham Farms Fall Punkin Fest. Last year we brought a rebuilt version of Mini-NASAW, the machine that became the 2012 World Champion Trebuchet, and fired it roughly 70 times during the afternoon, with most of the shots triggered by kids visiting the farm during the day! We will be doing the same this year, shooting fairly steadily between approximately 11:30AM to 3:30PM. Ask us questions, check out the machines, and maybe even pull the trigger on one yourself!
November 3-5:
The WCPC, the big show, it's back again in 2017. Science Channel pulling its sponsorship after the 2016 accident have hurt the non-profit World Championship Punkin Chunkin Association, so even if you can't make it, consider making a donation to support the event, and let them know that NASAW is your favorite machine!

The WCPC has been cancelled for 2017. See this post for more information.



Sponsorship

Team 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.

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!!!

Latest News


No 2017 World Championship of Punkin Chunkin

Posted by Matt - Aug 27, 2017
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:

2017 World Championships of Punkin Chunkin

Posted by Matt - Aug 12, 2017
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.

Fall Updates

Posted by Matt - Nov 02, 2016
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:

World Championships Back on for 2016

Posted by Matt - Mar 19, 2016
Last week, it was announced that the World Championships of Punkin' Chunkin' (WCPC) will be returning in 2016 to the Wheatley Farm in Bridgeville, DE, site of the event from 2007-2013. The insurance issues that necessitated moving the event from the farm field have apparently been resolved such that we chunkers (and fans!) are welcome on the property again, as the landowner and his insurance company are now satisfied of adequate landowner protection. It should be pointed out that the Wheatleys themselves are Punkin Chunkers (United Flingdom III), and did not want to ask the event to leave, but situations were such with the on-going 2013 lawsuit from the 2012 incident that they needed to do what they did. We are thrilled that they will have us back, and are looking forward to chunking again in 2016! More information can be read in the official press release and in the Sussex County Post. Team Urban Siege looks forward to returning to Delaware to chunk punkins with all our friends from November 4-6!

2015 New Hampshire Extreme Chunkin

Posted by Matt - Nov 10, 2015
Since the 2015 World Championships of Punkin Chunkin ended up being cancelled for the second year in a row, we were once again left without a hurling event to go to. A number of phone calls and emails ensued, and we decided to go off to the chunk happening at the New Hampshire Motor Speedway, the Extreme Chunkin, which was only 2 weeks away (October 24 & 25) when the Delaware cancellation was made! We had not really tuned NASAW to shoot for distance in 2 years, but we really wanted to compete with some of our hurling friends again, so plans were set for us to go! Some last-minute tuning was done with about 3000 pounds of counterweight (roughly what our last shot at the 2013 WCPC was with), but unfortunately one of those shots resulted in bending a main section of the throwing arm. Luckily we still have the original throwing arm, which was the one we shot with in 2011 and 2012, so that was installed just a day before NASAW hit the road for the long drive from Western New York to Loudon, NH.
