I'm an absolute noob when it comes to woodworking, but now I'm in the middle of my first (some sort of) drawer/shelves building project. I've glued together all four sides (store bought edge glued pine boards) with butt joints using clamps, and to me it seems like the joints are tight and solid, but in retrospect I feel like I should've used wood plugs cause that'd make the fitting so much easier. I used Titebond III.
Anyway, now I'm wondering if I should reinforce the joints to secure them more even if the glue has dried? Will it even make a difference with nails or screws at this point? I'm going to put in drawer slides that will carry some weight, so I don't want the glued joints to be the weakest link in the build.
