Jeckyl and Hyde Plans on the Horizon

There has been interest in the free trebuchet plans that have been promised, and no, they are not here yet. However, the plans for Jeckyl and Hyde, previously stated to be only partially released due to the number of problems we have had with the machine, are actually being redone so that they can be posted here in full. This is in light of what we have discovered as to why the trebuchet is not firing reliably as a King Arthur. Basically, it is due to how we have put the secondary cable guides onto the short arm. A simple fix, really, and the frame itself has been working tremendously well since the frame extensions were added this spring. So, keep tuned for the plans, they should be available soon. They will not be step-by-step ones, however, although they will be fairly straight-forward to follow.

The plans for both the Melon Felon and the Tennis Ball Trebuchet, however, are still not on the horizon for completion. The Tennis Ball Trebuchet is very similar to Ripcord's, and so will likely never be uploaded due to its similarity. And the Melon Felon was changed in a few dimensions as we were building, so redrawing of the plans after extensive measuring of the changed features is necessary, and Matt is currently out of town until Thanksgiving. Since he stores all of the trebuchets, nothing can be done until he returns in terms of measuring and drawing. This is also why there have been no launches lately, and will likely not be for the remainder of the year unless the weather is good over Thanksgiving break. Not likely in snowy Rochester.

Use "common sense" when operating trebuchets and catapults. Even little ones can be dangerous. Do not place anything you are not willing to lose in the plane of the arm rotation (this includes yourself, body parts, car windshields, cameras, etc). These catapults and trebuchets are capable of throwing just as far backwards as forwards, and the use of a backstop of some sort is recommended, though the use of one does not make the region behind it safe.

Also, just because the throw got away safely downrange does not mean the end of the danger. The arm is likely still swinging wildly along with the counterweight, and there is a sling whipping around. One thing many people fail to take into account is this sling; some people put a metal ring on the slip end of the sling and this ring can HURT when whipping around!

Have fun hurling, but please KEEP IT SAFE!!!
