The mailman delivered two little packages today. A 1-1/4" annular cutter, and a 6" 0.02mm/m level. I was expecting the cutter. The level was a bonus! It was a heavy little package for it's size. Understandable, since is mostly iron.
Here they are together...

I knew my desk was out of plumb, but wow. The directions with the level were utterly worthless. The stick figure diagram was confusing and horrible. I found a video on YouTube (in Chinese) that had English subtitles that gave me a clue what to do.
Adjusting level That's tomorrows project. Let's see if I can calibrate it.
