I constructed this from plans found in Wood magazine May 2011. I made a few changes. Instead of just a drilled hole in the arm pivot I used bushings which gives the brass shaft a bearing surface which cuts down on friction and allows for further distance when launching the peanut. I also waxed the bed to reduce friction after finishing the assembly with Danish Oil. Instead of knots I used loops in the string that is seized with rod building thread which make for a cleaner look. I can launch a peanut in the shell approx 20 – 25 feet.
Thanks for viewing!

That’s pretty cool. I’ve thought of building a treb or a catapult, also a guillotine and an electric chair. I have lots of strange ideas. The important question is, can you throw a cat with it?

If I had a life size Trebuchet, I’d just get in trouble but don’t think for a minute that I didn’t think of doing just that. Some how the wife figured what I was thinking and I figured out what she was thinking and that my friends was the last thought I had of building one of those for the yard.

What a great little trebouchet. 6-7 meters is quite a distance for a peanut. I guess heavier things will even go further. Like your work.
