I just attached the blade with a magnet. Zero. Then place the spirit level on the table. It easily adjusts to the perfect 90 degrees and is sure to find plenty of use in shops and in my tool box. This little tool can get the job done! Measure the angle! I've used it to fine tune seams and table saw blades. This is a must-have item for modern carpenters!
