Shop update #313 (11-1-23)
I’m working on a small catapult to use at a future Boy Scout campout. It’s 30″ long, 17″ wide, and 16.5″ tall. It is powered by 2 bungee cords and shoots wiffle type balls about 20 feet.
I cut 2 – 2×4’s at 30″ long and then notched them out for half laps.
Can you see the mistake that I made? The half laps are slightly proud and both on the same side.
Everything is held together with screws so that I can take it apart for transport.
I installed a 1/2″ all thread bolt to use as a fulcrum.
I did my best to drill a hole down the middle of the wider edge of a 2×4.
I screwed in a PVC end cap to use as the ammo cup and gave it a test. I’ll have better pictures of it in action next week.
