Here's a way to ensure a perfect seam between two pieces of plastic laminate. Clamp the router fence board on one side so the router bit rides down the middle of the seam. Even if your fence board isn't absolutely straight, the two edges of the plastic laminate will mate perfectly when you cement them to the counter. This is a big concern of mine, because I myself have had quite a few close calls and luckily walked away unharmed. Also wear your hearing protection while using the power tools.
Loss of hearing is a gradual thing and mostly irreversible.
I know you probably heard all this before, but it's just something I feel I should share with you because I know from experience from doing construction work and seeing first hand how many peoples lives are affected by not taking the safety stuff seriously. Fire Extinguishers are another safety device that should be in every shop no matter how small. There should be a fire extinguisher with in easy reach every 10'. I recommend you put one on two walls in the center of the shop, that way you are covered no matter where you are in your shop. One thing that some of you might not realize is that sawdust is a highly flammable material, and we all know that our shops will have a lot of sawdust.
