We are pleased to publish the first ever gift guide for the trebuchet and catapult maker! MAKE columnist William Gurstelle put together everything you need to get started making your own giant-flinger, or as they’re properly called… trebuchets and catapults! You might ask why we’re putting a guide like this on MAKE, catapult kits sums it up pretty well… “Because the world needs good engineers and scientists, and because the kids who will grow up to become engineers and scientists need a way to get hands-on experience with physics, math and engineering”.

Trebuchet connoisseurs and history buffs will find much to like in Sir Ralph Payne-Gallweys 1907 classic work, The Book of the Crossbow. Despite the name, there’s a ton of information devoted specifically to trebuchets. Reprinted in 1995 by Dover Press, it appears out of print, although used copies are findable on used book websites.

Metal, lots of it
If models aren’t big enough, then it’s time to build the real McCoy. But, novice catapult builders often find that full size machines made from dimensional lumber like 2 x 4′s quickly crack and break. So instead, consider using steel. And, nothing says merry Christmas like 16 linear feet of 1/8-inch A36 hot rolled steel angle iron lying under the Christmas tree.

Cable pullers
Price: $50
The counterweight on a big trebuchet could weigh tons. You’ll may need help to pull the weight down. One possibility is to use
a cable puller, a ratcheting lever that can move most anything. They run from $50 on up depending on the maximum load rating.

Elmer’s ProBond Interior/Exterior
Price: $7.00
After you’ve cut your trebuchet’s joints with the saw, you need to fasten them together. And they need to be strong and
often, rainproof. That means glue is involved. One of the best wood glues is Elmer’s ProBond Interior/Exterior. It’s not expensive and widely available.
