I normally do not install countertops, but have a new contract with a builder who requires us to install the laminate counters with our cabinets in the kitchen.
What is the best way to cut this stuff without chipping or damaging it? My countertop supplier will miter the corners and make slots for the dog-bones. But what is the best way to cut out for the sink with the backsplash in the way of the router? Do I tip it over and rout it with the counter upside down with a template? I know this may seem simple, but I don't want to screw this up and have to purchase material twice.

To scribe the backsplash, measure from the front of the cabinet to the front of the countertop, making sure that it is the same on both ends (the top is sitting in place). If one side reads 1 1/4, make sure the other side does too. Use a scribe tool along the wall to mark the piece. Putting tan masking tape on the splash will make it easy to see your line when scribing. For side splashes, attach one side at a time so you can scribe each one individually. This will allow you to cut them until each side is the same thickness. When scribing to walls, use a skill saw and cut at a bevel. Leave your line while you cut so you can sand to it with a belt sander.
For sink holes, turn the top upside down and use the skill saw. Cut on your lines, this time stopping short of the radius turns. At this point you can use a jig saw. Make sure that the fall off is supported so that it doesn't break off at the end. It takes a while to get used to installing countertops, but when you've done several kitchens, you get used to it.
