Living in a flood prone section of Louisiana, I decided early on that whatever I acquired would have to be small enough and light enough to pick up and move in the event of a flood. The shop that I was to set it up in was nothing more than a 24x24 metal building with a cement floor that I had built a few years ago in order to have a place to do a bit of engine swapping. Seeing the error of my ways I made an effort to insulate it to make it usable in the La summer heat. Two inches of Styrofoam helped some by dropping the afternoon temp to 90 deg. You just can't work on other people's guns while sweat is running down your elbows.
Sweat does wonders to gun bluing.
Also, I was becoming more and more aware of the shortcomings of the Smithy. Lathe was ok if you don't mind not having a half nut or thread dial. Threading up to a shoulder as on a gun barrel was real exciting. Tools became sacrificial. The mill section of the Smithy was a real joke.
