Trebuchet

I got bored one day and decided to make a Trebuchet here are some images and a rather poor video.

The build went well, with the only issue being how to get the stone to relise at the right time, this was sorted with a little trail and error, but the the end worked fine repeatedly.

Sorry for no build images or notes, i either did not take any at the time or they are lost with my old phone.

Changes that have been made since the images were taken :

The large batteries i used for weights at the end of the arm were changed for a bungie cord, which improved power and range lots.

A better support bar for the arm pivot as began to bend.
