Finally, some shots of the current progress.
This post has a few shots of the control panel innards. Also, I wired the admin panel as follows. I made 2-3 foot wires with female attachments to connect to the microswitch. On the other end of the wire is a quick connector and labeled tag (for example, P1 start with a female connector). The control panel has wires coming out of it that have the corresponding connector and label (for example, P1 start with a male connector). So, one the CP is installed it is easy to make the final connections to all buttons that are exterior to the control panel.
The other shot in this post is of the fan at the top of the cabinet. I did not plan properly so I could not use screws to attach the fan. The solution? Some cotter pins that I had in the basement. They are probably over 30 years old. I wouldn't doubt it if they were 50 years old. They were my dads. So, I got the cotter pins in the holes as needed and bent. It actually holds the fan in place surprisingly well. Just as tight as if I would have used screws.
