I am drilling holes for handrail brackets of the old strong type, the one with a center bolt. The handrail will be a 43mm round rod in inclined, oiled pine. It will also be steamed and finely curved.
Since you can clearly see in line with the handrail when going down the stairs, I realize that the handrail brackets must be placed very precisely. There isn't even a tenth of a millimeter adjustment margin after they are attached.
Said and done; I use a long straightedge to get the straight part exactly right. In width, they are also placed at the center of the wall stud behind the surface (beadboard + chipboard) to get a good fixture.
Of course, two out of six holes end up misaligned. I know why and will not do it again. Unfortunately, I have very little adjustment margin since the bracket must be centered on the stud width-wise.
Is it possible to plug the old hole with the same material and wood glue and then drill a new one with a few millimeter offset? It should be possible, but has anyone tried it before? Any tools?
