Orc Trebuchet - Fetchez La Vache
About this creation
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.

Thanks everyone for the compliments and kind words. William and I spent many hours this past weekend launching Lego livestock at each others armies. It was great fun for all. I'm glad that you all enjoyed the MOC as well.

Quoting Justin M This is just excellent! Kind of reminds me of Monty Python and the Holy Grail when the French men are hurling cows and all sorts of other animals at King Arthur:P Nicely done!
Very good Justin! "Fetchez La Vache" is actually fake french for "Fetch the Cow" and is what the Frenchmen in Monty Python and the Holy Grail say right before they launch the cow at our heroes. Kudos to you for picking up on the reference to the film.

Oh, yes, hurling cows at your enemies to reduce morale and spread disease! That is very fitting for orcs.

Looks great. Great that you can have it look the part and play the part. I made a Lego trebuchet once - it didn't look this good and I cheated and used lead for the counterweight.

That poor cow...Nice design, the counter weight was cool, and the whole build looks decent for a functioning trebuchet. Nice job.

Yes, hurling cows! Excellent work, it looks great. I'm sure your kids (and yourself) will get tons of enjoyment from chucking bovines at walls.
