I am a big fan of trebuchets and I was wondering how many lego weights are available? I know of the heavy bricks found in a lot of boats. They are 6x2x2 I think and are the same ones used on the crawler crane 8288. I remember from my childhood a weight that looked like a keel of a boat that was to keep a boat upright while floating. Does anyone remember that one or was it another brand? Any others that you can think of? Has Technic used anythig besides the battery pack?

Thanks

Tom

Can't think of anything other than the black brick 6x2x2 that you mentioned. It was used in several Technic sets back in the day at least

By the way: what size trebuchet do you plan to make? I too am a big fan of the brilliant machine, and have been thinking of building one in Lego

On a side note: I also really really hope to make a real one some day! Like a properly big one! That can throw old washing machines and other heavy objects!!

I tried making one when I was alot younger using some actual weigth lifting weights. I think I used too much as a few beams broke and the weight just made a huge bang on the floor! The real things are amazing! I sence a friendly competition coming on

Yup, mine was black but 1118 is the part number for the red one.

As far as size goes, I already have a few full size ones. I have one for "Punkin Chunkin" that will throw an 8 lb. (3.6 kg?) pumpkin over 1600 feet (500 m). I wanted to build some replicas of the machines I throw against (it's all in fun) just to "own" a version of it.

I wanted to use Legos just for the challenge and it's easier to work on at night while the kids are upstairs asleep. The welder and grinders are too loud for night basement work!

That video you linked to of the trebuchet throwing a burning piano was designed by Ron Toms, a true innovator in the sport. His FAT and F2K machines are probably the first real innovations in trebuchet design in over 800-1000 years.

They made a magnet brick that could be used as a weight as its most probably heavy. I think its a 4x4 brick there are smaller ones too such as 2z2 or 2x4.

There is actually an other Technic weight. It's very small, but it had an + (cross axle) on it to attach it. I can't find it on Bricklink, I'll try to find it in my unsorted lot, because it has a part number on it

You can see it in 8094:

Yes! That one

So, it's part number 70163.

I remember a weight brick: 6x2, 2or3 Stuss high. It came with a police boat city set in the late eighties I guess. It was used for trimming.

BrickLink number is 73090b.

Use the NXT brick with batteries in it. I remember making a voice activated trechubucket using mind storms. If you want the instructions are on NXTprograms.com.
