@drewnickel I know this is too late to help with your project (I forgot I had this account) I would imagine the sling slows the projectile down as it adds air drag. The sling takes a lot of time to calibrate. You don't want the ropes too long, and not too short. The release pin also needs to be bent slightly to help adjust when the free end of the sling will slide off, releasing the projectile. Remember from physics class that the optimum angle for firing a projectile is 45 degrees!

@JamesThWilliams kay, but I don't know if my catapult's 10 pound weight will fire it further. will I have to reinforce it and add more weight probably?

Use a different projectile tennis balls are extremely light for their size and as such are slowed greatly by wind resistance. You want to use the densest projectile possible, a lead ball would be best. You can go to a fishing store a by round lead weight for down riggers. By the way 100 feet is pretty good for a six foot throwing arm.

hey, I'm having problems with mine, I built a 6ft trebuchet for my science project, and I'm having trouble getting it to fire a tennis ball any further than 100ft. I'm using a detatched sling so the sling goes with the ammo, cause most of my trebuchets seem to not like normal slings and often fire backwards, how can I optimize for a dettatched sling to go further than what it's getting

damn, i'm making one right now for my senior project and am having problems

The Hinged Counterweight video responses are this same trebuchet, with some minor adjustments, relocation, and much better quality video. I filmed the current video with a potato.

the construction of the wood and all took about a day, tweaking the sling and axle parts on other spare time. The swinging counterweight took about another day, so possibly built in a good free weekend.
