Anyone know how to tighten a loose stair rail post? It's the end post of a railing that guards the stairway opening to our basement. It's quite wobbly now after years of two boys swinging around it to get down the stairs! There doesn't seem to be any bolts or screws going up into the bottom of it from below (looking up from the unfinished side of the basement). Could it have just been toe-nailed? I was thinking of using the pocket Kreg and drive some really long screws down into the flooring.
