I found this article written by Doug Smith, and I thought it was worth sharing… The original article can be found here www.smithrus.com
I was doing some repair work on a laptop computer today and realized I had not yet shared one of my most significant homemade tools for this kind of work. It’s simply an ice cube tray with each cube numbered in permanent marker.
I put screws and other small parts in the tray as I disassemble each section of the computer. If I’m following a numbered repair guide I try to match the cube number to each step. Otherwise, I just fill the cubes in numerical order as it makes sense. Reassembly is a snap and there’s no losing or mixing up those tiny screws.
Oh, and while I’m snatching kitchen items to use as tools, cookie sheets make great parts trays for longer-term projects. The whole project can be shelved to get it out of the way and then easily resumed without parts getting misplaced.
