Took about 90 minutes to cut and assemble this trebuchet for one of my grandsons’ history classes. Antiqued it with a propane torch. Not much to look at, but it threw a golf ball 97 feet! School principal made them stop “testing it” when they hit within inches of a school window. LOL. Made entirely of yellow pine, except for the metal pivot pin for the arm, the cloth sling, the trigger mechanism and a half inch plywood base. Also had about fifteen pounds of lead as ballast.

Even inexpensive projects can be fun. My grandson and his classmates loved it!

PS: date on pic is incorrect. Camera was not set. Made the trebuchet about 3 months ago.

A classic I wish I had as a kid….now your grandson can attach a few water balloons to it and have even more fun. Well done.

This is a nice project especially so since you were working with your grandson.

Nice post.

I assume that by this point the grandson has heard the tradition of returning the diplomats via trebuchet following unsuccessful negotiations, and has re-enacted the historical events?

97 feet! Wow! It always amazed me how simple things like that can make something go so far. Always makes me wonder how far they could chunk a good sized rock in the old days. Great job with the build. I am sure it will be cherished. All little boys like a lethal weapon.

Keep up the great work!

No, I don’t think my grandson has heard of the tradition of returning diplomats via trebuchet … otherwise he would probably want to send his younger brother! LOL.

Can we get a blog with the plans? I know a few grownup kids and real kids that could use one….

One of my sons made one last summer. It was about 4’ tall and would throw water balloons (safer than golf balls) about 120 feet. I was amazed at the accuracy. You could cluster shots in 6’ circle at 40 yards. As he was building this I was wondering how do you get it to turn loose of the rope at exactly the right time. Turns out that the trigger is a strategically placed bent nail. The guy that invented this ( back in the day) was pretty sharp.

BTW – Yours looks much better than my son’s. His was just unfinished 2×4’s , concrete blocks in a bucket for ballast and a dish towel for a sling.

Hey, the idea of blogging it and even including plans sounds intriguing but it will have to wait a few days. I’m in the middle of getting some medical tests done and it’s taking most of my time. Barely have time to answer emails and respond to comments, etc. Besides that, the ‘old lady’ has been on my case about remodeling her kitchen. My disability (bilateral peripheral neuropathy, among others) makes it impossible to do more than four or five hours of work a day and even typing is a real chore for me. Believe it or not, I could once type about 140 words per minute. It’s taken me close to ten to type this much now! But thanks for the support. I’ll do a blog as soon as I can.

Trebuchets are awesome. I actually can’t wait until I’ve got a chance to help my son build one for one of his classes :D
