I decided to organize all my parts into bins that allow me to easily see in a glance what parts I have. At first I was going to build standard shelving, but then I came upon a solution that's inexpensive, easy, flexible and fast. And it looks pretty cool, too!
Step 1: The storage bins...
The key feature for the bins is the hook along the back, that is designed to fit into their shelving systems.
These bins also have a 3" by 1" slot in the front for a label.
Other brands & models may work well, but I can vouch for these.
Step 2: ...and the mounting rails
Step 3: Preparing the mounting rails
Step 4: Mounting the rails
This would probably be a fine time to point out the obvious: You should be mounting this on some sort of finished walls, rather than on a wall that's just exposed studs. If you have the latter, hang 4x8 sheet of plywood on the wall, and attach the rails to it.
I seperated the rails by 4 inches, and used a level to guarantee some semblence of levelness. Although I mounted them myself, it probably would have been a bit easier with an assistant.
Step 5: Hang the shelves on the rails, fill with parts, label and resort
For $150, this gives me a really nice organization scheme. Parts are visible, classified, and easily accessible. I will be investigating using some larger bins in other areas to handle oversized parts, but so far, it's been an unqualified success.
