Micro Treb is a very small trebuchet built to scale for 25mm fantasy miniatures. It can throw 1/4 inch finishing nails about 30 inches at a low arc. It could probably throw a heavier projectile a bit farther.
Baby treb is a short trebuchet useful for throwing golf-balls, and Duplo blocks. It is also my first trebuchet, built by my Dad when I was in high school.
Treb Jr. is an experimental 4' traction trebuchet. It was made from the remains of oak pallets used to carry plate steel to Digital Corporation. The arm is a young ash tree. The fulcrum came off a dead lawn mower shift lever. The pouch came from an old pair of jeans. Surprisingly, I did purchase some bolts and rope for this machine.
Juggernaut is our first large scale throwing machine. We used this design for our experiments for 1.5 years. That time culminated in attending the 1998 World Championship Punkin Chunk
In 1999, we rebuilt Juggernaut to be larger, stronger, and more dangerous than before. We abandoned our traction technique and moved on to using a counterweight in a more traditional form.
The Higgs Throwson trebuchet was built to compete at a competition held at the Higgens Armory in Worcester MA.
In 2000 we decided to take a two prong attack to our siege craft. We simultaneously started building both a gigantic Ballista, and a centripetal human powered machine.
Baby Ballista was constructed while we were trying to design Ballista Jr. We had realized part way through that we weren't quite sure what was up, so we built Baby Ballista in an attempt to figure our what was going on.
Ballista Jr is Team Tormentum's first ballista, and first torsion machine.
Mista Ballista is Team Tormentum's Torsion Division competition catapult.
Baby Hatra Ballista is a model of a ballista whose Archaeological evidence was found near Hatra Iraq.
After building and testing Baby Hatra Ballista, it was clear this design was worth pursuing. Eric decided we needed a mid-sized model which we could then enter into the World Championship Punkin Chunk in the 10 and under category.
Baby Onager was constructed in preparation for building a mid-sized onager. The basic torsion engine design was taken and improved from my Baby Ballista model. I'm going to recycle metal parts from Ballista Jr to build a mid-sized onager based on this design. If that works well, I may build a second for use in winter snow ball fights.
Onager Jr was our first torsion siege-engine of the medium scale that functioned well.
The UTM, or Universal Torsion Machine, is a small scale torsion engine designed to answer the oft asked question, "What is the best Torsion Engine configuration?"
This is a Cam Drive Trebuchet I'm calling an ASOK (Arm Slides Over Kam.) This small machine stands 2' tall and has 4 lbs of counterweight. At the moment it can hurl a small key-chain koosh ball about 20-35 feet.
The Cardan Gear Linear Motion Trebuchet is an adaptation of the motion found in a Cardan Gear adapted to a straight track-drop trebuchet. The straight track drop is an idea used in a FAT (Floating Arm Trebuchet), or in our Baby ASOK (Arm Slides Over Cam). The Cardan gear was invented to accept linear motion from a steam piston to create circular motion. For this trebuchet the geometry (without the gears) was used to fling.
The Scissor Jack Near-Linear Motion Trebuchet is an adaptation of the common Scissor Jack as found for lifting automobiles. The motion found in a Scissor can be adapted to a near-straight drop trebuchet. The straight drop is an idea used in a a FAT (Floating Arm Trebuchet), or in our Baby ASOK (Arm Slides Over Cam).
What do you build when your young kids see you playing with lots of catapults which are all to dangerous for them to play with? They know it's fun. They see you launching stuff. They clearly need a catapult of their own.
What do you do in Massachusetts Mid January when the kids are bouncing and, for whatever reason, it's almost 70 degrees outside? Build a catapult, of course. Well, it's not exactly a catapult, but it does throw stuff in an amusing way. This vacuum bazooka was inspired by the title of a book, Vacuum Bazooka, Rainbow Jelly, and 27 other experiments. I didn't actually read the chapter on vacuum bazooka. I just made stuff up.
Siege-Engine.com is a home for many esoteric and ancient catapult replicas. Looking for parts for our many machines has lead to the acquisition of many mechanical parts others may not be tempted to hold on to. Such was the case when my propane tank expired and could no longer be filled, and when a 1.5" AC actuated air valve came into my possession around the same time. What to do? Isn't it obvious?
