What is the standard counter top placement procedure?

Put the top in place and see how it fits to the wall..if it's bad use a set of scribes( A device that looks like the compass you used in grade school to make circles) to draw a line on the top that follows the wavy wall line. Sand or cut to the scribe line. Place the top on the cabinets and check the fit again... If it's good screw it down to the cabinets from the under-side. Be careful not to use screws that are too long!!!!!
