My townhouse has some outdoor stairs built out of 6" x 8" lumber (i.e., the first step is comprised of two pieces of lumber (with no "nosing")). A couple of the steps are rotten and I need to change the lumber. There is a metal railing along the stairs, which is held down with screws in the lumber. I will need to remove that railing when changing the lumber. When comes time to re-install the railing, will I be able to reuse the same holes for screwing the railing back in place? I don't want to leave some visible holes (in the steps that did not need to be replaced) if I need to use different holes?
edit: The reason for me saying the railing needs to be removed is that (I believe) there is a nail underneath the railing metal plate on the first stair. I cannot confirm without removing the darn railing. After I asked the question about reusing the same screw holes to one of my neighbors (who is no more handy than I am), he suggested that I cut the step off near the nail and slide out the lumber (instead of taking off the railing). I am not sure how I would cut off the lumber in the first place, let alone cutting it close enough to the nail under the metal railing. Based on the (somewhat comforting!) answers below, am I correct in saying that using the same holes, with possibly longer lag bolts, would maintain a safe railing and be much easier than trying to cut off the lumber near the spikes?
