One Rod, Three Holes...

What a lucky rod...

As you might be able to see, I kinda messed up with the first holes. I will tell you how to do it correctly the first time around.

Ok, now it's time to bust out that 5/8" wood boring bit. But, first, before you starting boring this wood (similar as how I am probably doing to you...), you need to take some measurements. Measure 4.5" from the top and make a line across the entire width of the vertical support. Now, along that line, place the tape measure and mark the center. In my case, it was at 1.25". Put a vertical pencil mark there. Do the same thing on both vertical beams. Now it's time to bore. Place the pointy tip of your bit on the intersection of the lines and, while holding the vertical support from behind, bore all the way through being careful not to burst through the other side.

The next step is, if you choose to, to screw the two remaining 55" beams together. This will be the arm. The reason I made it thicker is so that it wasn't wobbly. There is a downfall to this, however, it may cause degradation in performance because of the added weight. There are other designs that I will discuss later on.

Now you need to bore a hole through the throwing arm. Measure 11" from one end and make a line across the width of the arm. Now, like you did before, measure the width of the arm and mark the middle point. For me, again, it was 1.25". Make a vertical mark there to create a cross. Bore through it like you did with the vertical support beams.

Now, slide the wooden dowel through all of the holes. It may be difficult. This is a good thing. You may need to use a hammer to get it to go through.

Counterweight Container:

Ok, well, this is kinda up to you. I will be explaining how to build what I built for my trebuchet. There are a lot of great designs. I just kinda ghetto-rigged one using what I had. Of course, it's not nearly as ghetto as it could be. This project is relatively un-ghetto.

This box is good for holding many different kinds of weight. You can use wet sand when you are done. In order for all the wet sand to not leak out of the bottom, you can use some caulk or glue or anything that will fill up the cracks. Shoot, you can even put a ziploc baggy in there. Trust me, if I wasn't shooting for a psuedo-acurate medieval look, I would have done all sorts of crazy stuff. Duct tape would also be a great way to seal up the cracks and such.
