    I am currently redoing floorboards in my bedroom approx size 2.2 by 3.2m. Some of the joists have twisted so there is some work to be done on getting them level for the flooring. Any tips on how to find the high point and to check a level over the long run as the joists are running parallel to the short edge. If i had something approx 3 meters with a straight edge i would be able to tell which joists are higher or lower. Any tips?

    Get a load of little blocks all the same size with a line marked on (even lego bricks) set them out across the joists. get a laser level and scan across all the blocks - you will see instantly what is high/low.

    Laser level and an old fashioned "yard stick - metric version.

    Fix the laser level at 500mm high in the corner of the room and turn on. It should give full coverage.

    Place the 0 end of the yardstick on the end of a joist and read where the laser line crosses - subtract 500 from reading and write result on joist at that point. Move 400mm along joist, repeat measurement, and continue along every joist.

    Makes you wonder how people did things before laser levels were invented
