This is project I did with my daughter, will have to find the progress pics and add them later (now added). This is for a school project called “Trap the Teacher”. The third grade was studying simple machines and the student had to make a machine that used simple machines in series to capture the teacher, like build a better mouse trap. After talking with her, she chose to make a catapult. Since I have been wanting to make one of these for quite a while, I dug up the plans from an old American Woodworker issue and I went to work making a kit for her to assemble. She did get to make some crosscuts on the RAS, she used the palm sander, and the old mallet to knock everything together. I got sent out on a job in the middle of this project and we rushed to get it done in time. Everything is red oak, except for the trigger which is a left over piece of Cocobolo..and they said I would never find a use for it.

The tray down the center has not been made yet, as this was modified in to a trap. The sling became a rope trap, and the lure was her teachers favorite…chocolate.

I went to school and helped her with her presentation and such, as you could imagine it was a big hit with the kids, the teacher was of course a bit taken back at how quick it worked!

Very cool looking project. I’m sure the kids were fascinated! How far did it shoot the projectile??

Very Cool. I made a quick and dirty one of these a while ago and it was loads of fun. I’m keep telling myself I need to make another.

Awesome job, my daughter and I also made one this weekend, or at least started. She is part of of a group that competes in DI (destination imagination) Where with a skit and props they need to solve a problem. Theirs is to get a hacky sack over a barrier and they choose catapults to do this. We have 3 of the 4 prototypes completed, a lever with a conveyor belt feeding systems, a Mangonel, and a Trebuchet. We have one last one which is a slingshot, I wanted to do a balliista but she wanted it to look like a tree. She is the boss on this one. Anyway good shooting…

I can’t wait to make one of these. I have to finish some furniture I started for the wife first though or I’ll never hear the end of it. :)
