Now the box is almost finished. Most of the hard work has been done, what is mainly left now is to install all the control cables, the PCB for those control cables and also I need to change all the screws to stainless steel ones so they don't rust. I also need to order some enamelled wire so I can wind the transformer that should be placed on the piece of plexi glass you can see in the box.
I did silver plate all the copper strips inside the box to avoid corrosion.
I am very curious to see how well the box performs. I will probably have some insertion loss since the strips between all the relays aren't matched but hopefully it won't be too bad.
Here are some pictures
