I didn't make an instructable while I was building my table, but after using it for nearly a year, it's become indispensable whenever I need to find a screw or other small part that's been shuffled to one of the large catch-all containers scattered around my shop.
Step 1: How its Used:
After the part has been discovered, a 3" opening on one of the table's ends allows you to sweep the unused parts back into their container.
Another feature that comes in handy is the table's clear top. As I've done in the photo, the table can be set on top of a lightbox so all of the parts are lit from the bottom. Sometimes spotting the shape of a single part, among hundreds similar parts is easier when everything is silhouetted.
The clear top also makes it easy to spot errant components that miss the table and end up underneath.
