The biggest pain was the electrical sub panel as we initially installed it upside down and Kevin the electrician wired it into the main panel without noticing. He used 4 gauge wire and man, trying to bend the stuff in order to invert the box was pretty much hell. But I managed to get it in and wired up. I screwed the face plates on the sockets this evening and threw the switch to test it all and everything is working. 6 double 110V and 2 240V sockets all working to spec.
So now all I need are my tools and I will once again be in the guitar making business. I am really looking forward to this. I have to thank my mentors Greg and Dave without who I would have never been able accomplish anything.
