I know how to and all I have the screw gun and 16 1" screws, and a ruler. I have a few ?'s though. 1. Should I put them on the sides or infront/behind the corners? 2. When I play I get a ton on shaking in the whole house, it gets to the point where I hear the rumbling of the contents in/out of the room more that my actuall sound sometimes, will castors elimate some of this by chance? 3. Any thing I should know?
