How to build a trebuchet? - blueprints of trebuchet
I'm in a group of citizens, and we grow pumpkins as a fundraiser. We typically a few hundred more and want to build a trebuchet. Is it hard and how long it takes to build a trebuchet big enough to launch a pumpkin £ 5 1 / 4 miles? What a little wood, the economic exploitation? I have to buy access to free wood rail, but must be other materials. Where can I find plans or drawings?

Trebuchet.com If you sell the plans. They also have an excellent program, simulation software ($ 25) you made in their design work and all the details before cutting a single piece of wood.
With this program you can contact the checks and balances and pumpkin sling length in connection and the length of the limb and all that and make a detailed analysis of the amount you need to do to remove the pumpkin 1 / 4 mile.

It is impossible to do, but would not be cheap.
Existing Home squash Trebsen comparison requires a machine * at least 50 feet high at the end of long road with a bundle of at least 40 yards and a counterbalance at least a ton. Axis of its frame and should be able to this large load with a safety factor, which is seen sometimes as a counterbalance to the support of 10-times available.
I have no idea what "Wooden Railway, but you would look at things, like 2x12 in size 20 to 30 meters for use in the frame.
It is too ambitious for a first attempt. Even the removal of half the desired distance is more than a handful.
You need to run a pumpkin about 400 feet. This means that you will need a launch velocity of 63 m / s or 140 miles per hour (assuming no air resistance, that is) at this speed is important. It takes about 4540 J to be distributed to your pumpkin if it weighs 5 pounds. It is a little more than a round of Winchester, 308 Off to their trebuchet will be offset, the size of a small house. And from the wood of any kind, can not resist the force, you need steel beams and securing good at least.
