Making of the box

Firstly I measured for the wood to the correct size I needed for the time capsule. I cut the 25m x 50m Timber with a saw my dad had in the garage. The saw gave it a nice clean cut although i will still have to sand in down afterwards. 

Once I cut all the piece to size I inserted a random CD in the space so I knew for sure it was going to fit. 

This is the 12mm Plywood I used for the box. I choose to use this particular wood because it is very thick therefore will last longer when underground. I will need to measure up the size and cut again using the saw. 

I then nailed the four pieces of timber together with and nail gun. As this gun is very powerful I had someone holding the wood together so it would move. 

Below is the finished box. I nailed the Plywood onto one side and left the other side so it can be taken off. 

The lid has two strips of timber nailed on which fit perfectly and makes the CD in place. This makes the lid stay with the box although it can be taken off. If i was to bury this time capsule I would nailed the lid shut so nothing can get inside and destroy the CD.
