Like I said, he wants it to work like a compas - levels are for measuring difference in height not direction.
Spudgun is pointing it in a different directions and expecting the bubble to tell him if it is lined up with his mark. Very basic mistake.
dont think he is ready to be a
tiler just yet. Needs some training quick.
Hey Spudgun, I am not knocking your efforts, just trying to be helpful - I have seen the 'spirit level' mistake made many times before.
