Find a drill bit a little less than the diameter of the screws you are using (try to match the screw 'body' with the drill bit). We'll use this to make a 'pilot hole' into the wood - the screws go in easier and they won't split the wood. Have a friend hold the first piece of your rack onto the wall in the correct spot. At each stud, drill two pilot holes through the rack and into the wall. Remove the rack and drill the holes in the wall deeper in. Next hold your rack back onto the wall and screw in the wood screws all the way. You need to attach the wood to 2 different studs so it doesn't tip or rip out.
