FunSteak said:Many good-quality levels are adjustable. To check one for accuracy is simple. Place it against the wall and get the bubbles perfect, then draw a line down one long edge. Then flip the level over 180 degrees and compare to the line. If it's just right, the line should align perfectly with the other side. If it doesn't, you know it's off and needs adjustment. There is often a small setscrew near the vials that can finely adjust the vial's position.
Cheaper levels don't have this adjustment, BTW. My old mahogany 2' and 4' mason levels do, and I've got them dialed in perfectly.
Interesting-- I did not know that! )
