Thanks guys. Good advice from all.

At this point, I'm going for practicality that looks nice and clean.

The actual gun room will be separate front he work space and will be for display for me only. I love to just stare at them from time to time and don't like to paw through the safe or place them on the floor to enjoy them.

I like the dowel idea. Are there certain species of wood to avoid which may affect bluing?

The maintenance room will be around 6x10. I have a good sized house so I will not likely hang out in there unless I'm working on guns or reloading. Think "nice office" more than "comfortable den".

I'm far from retirement so my time is limited. 30 years from now, I will go for the man cave thing.

Any photos of display/storage options?
