Janus Construction is Complete

We have finished building Janus, the Floating Axle King Arthur/ Floating Everything Whipper (FAKA/FEW) Hybrid. The frame, which was finished several weeks ago, got stained similarly to Medieval Postal Service, and we got the steel and aluminum ordered. Last weekend (March 13-14) was spent in Buffalo machining and welding. Thanks again to Great Lakes Pressed Steel for helping us out with getting materials and for shop space to work. We were not able to make the arm at this time since the aluminum for that had not come in yet, but Jason took care of that later in the week and brought everything to Rochester Friday evening. Chris and Matt took the trebuchet out yesterday for initial testing and verification of a few systems, more on that will follow in a day or two.

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!!!
