Calibrating Starrett level

Wow these levels are so sensitive, specially the new model.

I got the used one calibrated within about 15-20 mins. But it takes me forever to work on the new one. Still not perfect yet but I’m so tired already. Haha. Don’t get any younger anymore. *sigh.

New but bought from 3rd party

I’ve got them all calibrated already. It was fun at first but I’m more of a perfectionist so I just kept going. Takes forever. Lol
