Possible - New idea for brick cutting table

[jonv]

patjer1 - it's because you cut them wider than those below so they vary in the positions where they line up on the bricks below. If kept perfectly on bond so that the sides of each brick are lined up with the centre of the brick below the desired angle on the sides is exactly the same all the way around. If you drift away from that then adjacent bricks sit differently as they straddle the flat faces of those below and thus the angles between their side faces will vary a little. It's probably better to cut a narrow brick from time to time to bring them back on bond. Hope that makes sense - if you take a couple bricks and adjust where they sit on the bricks below it should be clear where your varying angle is coming from...
