It wasn't until I got this gate piece screwed, glued, and hung up that I noticed there's a slight warp to it. I think it's due to just one piece in particular, but at this point I think I'm cooked. (Would have to drill out pocket hole plugs, dissolve the glue, and unscrew to replace the board.)
Is there any way to fix this? Hand plane it perhaps? (Newbie woodworker.) It's not awful, maybe a 1/4" gap. Enough to bug me though.
