Updates: It's here. Happy hurling at the VTPC.
Good news! We now have a real battle in the Battle of the Bands, "Stonecutters", a local rock band out of the Morrisville area has just joined the battle. So far, it is "Honeybee" (soft rock) against "Stonecutters" (rock) squaring off around 11:30am. We've love to have more bands enter. Only $5 gets you into the battle and all the Pumpkin Chuckin events! Walkons welcome!
The featured bands, "Wilbur's Dog" and the "Hubcats" will be playing in the afternoon.
Also we just got another entry in the heavyweight division bringing out total to three heavyweight trebuchets!
Exciting news! We have a local genius James Spanier who built a huge trebuchet for the "Throw for Show" category and also a local 2 family contingent building a slingshot for the same division. I can hardly wait to see them in action!
Timing: I've moved the schedule up a little (check schedule below) to accomodate people who might want to get home early on a Sunday night. Battle of the Bands starts at 11:30 and first round of competition starts at 12:30, with the last round and free-for-all around 3:00pm.
Vision: We want to hold a fun trebuchet (rhymes with yesterday) hurling contest to raise money for the Lamoille Family Center in Morrisville, VT. The competitive hurling is limited to 4 main divisions. Each division will compete on distance.Other trebuchets, or catapults, or air cannons are encouraged to come and "throw for show" along with the other contestants, but if they do not meet the division specs., they will not be part of the official competition.

Who can participate in the Pumpkin Chuckin' Contest?Open to anyone to compete. One person or a team of up to 8 people. We are hoping to get kids of all ages, cub scouts, boy scouts, brownies, girl scouts, universities, companies, etc.
In the bantamweight, lightweight and middleweight divisions, older people may suggest ideas but the trebuchet must be built by the team or individual.
Similar to the Soap Box Derby; moms and dads can help with suggestions, but not actually work on the trebuchet.
-----
Schedule of activities on Sunday, October 4th:(These are approximate times. This is contingent upon the number of entries in the trebuchet contest and Battle of the Bands. If there are a small number of competitors, times will be moved up)
9am to 12:30pm: Assembly, safety inspection, weighing, measuring, testing and tweaking of trebuchets
11:30am to 12:30pm: Battle of the Bands (only 2 bands so far, this time could change)
12:30pm: Round one: First shot of trebuchets
1:30pm: Round two: Second shot of trebuchets
2:00pm: Hubcats (bluegrass/folk)
2:30: Round three: Third shot of trebuchets
3pm to dusk: Awards followed by free-for-all hurling, cleanup and music by Wilbur's Dog (progressive rock)
-----
SAFETY: All trebuchets must have a safety device (like a C-clamp) to stop the throwing arm from firing prematurely during loading of the projectile. Another excellent safety device is a support which can be placed directly under the counterweight, preventing it from falling.
Once the counterweight is lifted, the trebuchet is dangerous (even the small ones). Be careful not to put hands, feet or any body part in the potential path of the throwing arm or counterweight. Put the safety on immediately after the counterweight is lifted (before loading the sling, etc)!
All trebuchets will be inspected before firing and must pass the inspection to fire.
-----
Rules:Total weight of trebuchet including counterweight (not including projectile) may not exceed limit. See table above for weight limits for 4 divisions.
Height of trebuchet including throwing arm fully extended (the un-cocked height, straight up in the air) may not exceed limit. The sling is not included in the height limit, so the sling may exceed the limit.
No digging into the ground is allowed (like a pit for the counterweight to fall further). You may use the ground to stake the trebuchet to prevent rocking.
----
BYOP: Bring your own pumpkin (or tomato, or whatever you want to hurl). We may have some rotten vegetables donated or for sale on site, but there is no guarantee. We suggest you have 3 prime pumpkins at exactly the right weight for the contest, and several other for practice and free-for-all at the end. Water balloons are an easy projectile. Be sure the projectile is AT LEAST the required weight.Projectile must weigh at least the limit or more. Bantamweight = 3/5 ounces, Lightweight = 3 ounces, Middleweight = 1 pound, Heavyweight = 5 pounds.
Judges will weigh trebuchet and projectile and measure height before firing. Total weight of the trebuchet (including counterweight) must be UNDER the limit. Weight of projectile must be OVER the limit. Height must be UNDER the limit. No part of the trebuchet may go over the limit during firing, except the sling.
Competition: The competition is similar to a shotput where all the contestants fire their weapon, one at a time, each is spotted for distance from the center of the front of the trebuchet. The bantamweight competitors will be scaled up by 5, lightweight competitors will be scaled up by 2.93 to reflect the distance they would throw if they were 10 feet tall. The middleweight competitors will be scaled up by 1.71. We plan to announce the name, weight, height of each trebuchet and team members before asking them, "Ladies and Gentlemen, please fire your weapon!"
Just to be clear, the distance is measured from the center of the front of the trebuchet.
There will be 3 rounds with a pause (roughly 30 minutes) between rounds for tweaking, etc. At the end of the third shot, we will announce the awards, then start the free-for-all hurling for fun.
Reason for limits: The weight and size of the trebuchet is limited (given the short time to the festival) to allow teams to more easily assemble and transport their trebuchets to the contest.
-----
Scaling: Trebuchets "scale" very well. All things being equal, a trebuchet that is twice as big will throw twice as far. However, it will weight 8 times more and throw a projectile that weighs eights times more. The reason is that something twice as big, is twice as wide and twice as deep so the volume and weight increase by a factor of eight.With this in mind, each division is 5 times heavier than the division below it. Doing the math, this scales to 1.71 taller (cube root of 5). So each division is 1.71 times taller than the division below it so they can be compared against each other to award an overall "Best Design" prize. The bantamweight division will be multiplied by 5.000. The lightweight division distance will be multiplied by 2.924 and the middleweight division will be multiplied by 1.71 to accurately compare against the heavyweight division. For example, if a lightweight trebuchet throws 50 feet and a heavyweight trebuchet throws 145 feet, the lightweight trebuchet is scaled up to 146 (50*2.924) feet which beats the heavyweight trebuchet. This scaling will be used to award the overall "Best Design" prize. Each division will also have a best distance prize.
This gives a young kid a real chance to walk off with the most prestigious prize, no fancy metal working or wood working shop required, just brains and persistence.
Loading must be done totally with human power, no electrical or other assistance.
All trebuchets must be only gravity powered. No springs or pneumatics or other power sources.
