« Part 1: The Frame Part 2 of The Trebuchet Project series Part 3: No More Baseball »

Well, I did find my steel rod today for the swing arm axles.

The two axles are held in place with washers and cotter pins. I’m glad I bought extra length of rod. The trick is to make sure you have the washers sandwiched on each side of the swing arm and on the insides of the frame and bucket with cotter pins as tight as possible. If it is not tight enough, there will be just enough wobble to allow the bucket to hit parts of the frame while it makes its swing. I realized this quickly through testing it. So, I had to redrill my holes through the rod for the cotter pins.
After seeing what had to be done. It didn’t take much to get everything lined up and working right. I still have to finish the trigger mechanism on the arm. I also have got to round up some one liter bottles for my counterweight.
More to come.
