Great job so far Dustin. Running the 220 for the heavy machinery is always a little tricky because it you run it inside the wall it requires that you never move anything very far once hooked up and that you never replace it with something that requires more current draw and a larger size wire. For those reasons you may want to consider running those circuits on the face of the walls with either a wire mould or using armoured cable. If you run them down low they won't be that noticeable.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
