Orc Trebuchet - Fetchez La Vache . . Today my son was asking me about siege weapons that he could build for his Lego LOTHR Orc army. He hadn't had much luck with catapults so I suggested a trebuchet. After a little explaining and a few YouTube searches for trebuchet videos, he had the general idea. Of course he seemed to be having so much fun trying to engineer his trebuchet that Daddy had to try it too. So here's what I came up with... it's not pretty, but it works surprisingly well. Here we see the orcs with their trebuchet. After all, you can't have an orc trebuchet without orcs. Here's a view from behind. When the arm is positioned down, and the counterweight raised, the stored kinetic energy in the machine is ready to launch whatever the orcs want to send hurling towards their enemies. Here's a view of the raised counterweight. I originally thought that I could use a battery pack from a Lego train engine to weigh down the front, but that actually proved to be too much for my trebuchet arm design to support. My second choice was to use the bases from collectible minifigs as "plate weights". There are 32 of them in there in two stacks of 16. Here's a shot of the payload being prepared for launch. "MOOOOOOOOOOO!!!" And there you have it... a functioning trebuchet. Again, not the prettiest build I've done, but in this case I'll take function over form.
