Here comes my freshly restored spirit level.
This time, I also had to recalibrate it. To secure the glass vial with the bubble, I used a linseed oil putty that I made myself by mixing chalk with linseed oil varnish.
The previous reflective element (foil) had been badly worn by time, so I replaced that as well. Finally, I treated the body of the level with Avalon Arbeitsplattenöl, a moisture-resistant oil.
Enjoy the before and after pics!
