Sometimes work follows you home... today, my co-worker came in and asked if I could look at her microscope. After ten years of constant use, it was finally starting to show a bit of wear and tear. Well, I got it all apart and the rack was a bit messed up, and it was full of dirt and debris. So after a great deal of cleaning, it went back together... a bit to clean, as the friction mechanism now was to loose, so I had to build a small friction tab to keep things cinched up. It appears to be working, so we shall see once I get the rest of it back together. All this and it only took three hours LOL... Let us know your fun work experiences.
