my goal for ours is 300 foot! weve hit about 200 now, its insane seeing a pop bottle flying 30 or 40 foot off the ground (or more) and several hundred feet distant

You may have to add to the hight of the machine to add to the distance.

Also dont know if any of you are big fans of Mail Call, or Moster Garage. But the big guy (a.k.a the admin for Trebuchet.com) appeared on both. He brought a quarter scale treb to the set of Mail Call, he then built a machine like Triton's for Moster Garage. Believe it or not you learn quite a lot from those two episodes.

MAIL CALL ROCKS!!! for some reason R Lee Ermey was at our memorial day parade (which i was playing in) and i got his autograph. Monster Garage is also awesome, the delivery truck episode is my favorite

Nice! Now launch an old computer monitor, and don't forget to take a video

Yeah, Black Six, Science O. rocks. Plus, I've got two more years after this one of Science O. goodness, which makes it even better. I'm mainly a builder, currently working on Tower, Storm the Castle, Robot Ramble, and Wright Stuff. Good stuff, I love Science Olympiad.

That's a very nice catapult there, Triton. As G-force said, you should hurl a computer monitor. It'd be like LOTR all over again with the huge boulders. How long have you been working on it?

Post by **Triton** » Wed Oct 12, 2005 5:57 pm

weve been working on it around 6 or 7 weeks total, 1 hour a day 5 days a week, i doubt it could throw a pc monitor tho

we used a comb of arc and mig welders. i plan on taking some videos so dont worry!
