I woke up saturday morning and asked my kids (son-12, daughter-9) what they wanted to do. As usual, neither of them had any idea on what they wanted to do. I began making suggestions, such as wash the trucks, run for mayor, kidnap a baby elephant, cut the grass…....some where in the mix i said, “build a catapult”. that is what they chose. Of course I have never built one of these, but i have watched pumpkin chunking’, so that makes me somewhat of an expert.

after a trip to Lowe’s and ~$45. we have a trebuchet that can throw a ball about 35 yards. we are still tuning it in and i think we can get 50+ out of it.

It is constructed using 6-2×4s (pink because, well, i have a 9yo daughter), 21” of 1.5” pipe and a cylinder head from a chevy 350.
it really was a fun weekend project.

Where dad?”

“Sweet.”

That is great.

I also built one a few years ago:

I still laugh when I look back at that thread. Unfortunately, it looks like the comment by a LJ who claimed to be a lawyer (cr1) was removed. He explained how I could end up in prison with my life ruined. So far, we still have the trebuchet and I am still enjoying my freedom!

Yeah man! I built one for my son’s 5th birthday for water balloons as well. The kids in the neighborhood still remember that one even 10 years later. Some had the most fun helping with the launch end of it and the others enjoyed the catching end better, but no one was left out. I used a 50 pound weight from a weight bench the previous homeowner had left in the shed and was able to keep the center uprights closer together that way. I hear that the “modern” and more efficient way is to make the weight drop straight down. Behold, the floating arm trebuchet….

we hadn’t even considered using water balloons until sunday evening. but, that is what will be using next time.
as for the floating arm? well, i want this to be a learning experience for the kids. so, i started with something basic and plan to improve with the next, and the next, and the next….....

Great quote and project with the kids.

It is a good day when two of the top four projects on the homepage are siege weapons! LOL

Does that mean that a battering ram can’t be far behind?
