Don't let the uninsulated and exposed 2X4 framework discourage you from taking a look further... This is where the magic happens!
My "Labratory" consists of a work shop attached to a two stall garage. Here I have electricity, domestic hot water and plenty of space to let my creativity run rampant. Over the years I've collected a wide variety of tools both old and new and with the addition of primitive lighting equipment, a massive dry erase board, personal protective equipment and the ability to research many schollarly sources; my labratory puts to shame many "Backyard Scientist" who would settle for making some small explosion and not bother to take the time to explain it.
Occasionally I might need to do something that would I prefer not end with someone's house burning to the ground. In these cases I'll pack up my lab equipment and take a feild trip to a more safety oriented venue.
