Trebuchet sling details including the snap link release...

I thought this was a good description. You see trebuchets on youtube, but no one ever shows how they put it together. Hopefully someone will watch these and give me some good pointers, because this is definitely a trial and error type deal!

I did try covering the rebar with duct tape to smooth it out a bit but the snap link kept falling off---and the way I have the rebar attached it's really easy to bend, shorten or lengthen--all very critical adjustments!

thanks. we finished our trebuchet and it is almost 15 feet tall with the arm pointing up and we launched it but it went back wards. What do u think it is I think it is either because the nail that has the loop attatched to it so when it releases was straight and wasnt bent or the pouch was to small how did u make your pouch

@oldironside23 I've discovered that instead of my basic sling like you see in the videos I had to turn it into a pouch. one side of the sling is open and the opposite side (the one with the sling leg that fies off the end of the throwing arm) is actually sewed up about 6" creating a little pocket whatever you're tossing kinda sits in. I reinforce that with a metal grommet and some rope to hold it together.

The sling in this video lasted 25 throws till it was destroyed!. I currently am using a dufflebag i cut up for the material--and that is getting chewed up pretty good too!

I am making a (HCW)sling trebuchet for a school event that will lauch a pumpkin of about 3-4 pounds. How lonng should i make the sling compared to the long arm and is there a way for me to make a trigger like yours that is not burried in the ground but attatched to one of the framework peiced of wood on the base of the trebuchet

@oldironside23

A good way to start with your sling length is to make it the same length of the longest part of the throwing arm. My long part of the throwing arm is 7 feet long, so i started off with sling legs 7 feet long. Right now, my sling legs are 4 1/2 feet long, and I consistently toss stuff 150 feet in a straight line (LIke a fastball in baseball).

Very interesting

Thank you. I have always wondered how the other end of the sling released. Now I know. :)
