Ok, some of you guys and girls are saying that you should drill up from the bottom to the PVC.
If anyone you know has the proper equipment do this.
1. take you PVC pipe and cut 1in or how ever big your board length is.
2.Make sure it can slide right in. Or fit right on top of the board when the board is on its side.
3.Caulk your PVC to the board.
4. Make a slot on a big board (that is lying on its side)
5. put the pvc pipe with the baord attached to it and slide it in.
6. Nail it, and your done.
