So i’m finally finished my table top glue up. It looks pretty good, but there is a spot on one seam about 12” long in the middle of the table where it looks like there is a small gap between the boards – see first pic, and for a comparison to a clean seam, see the second pic. when i say gap, i mean the boards a slightly separated, but there seems to be glue filling in the gap. I haven’t yet sanded it down but my guess it that it is this way throughout the thickness of the board.

Any thoughts on what to do about it, to minimize the effect after finishing? The boards are maple, and I intend to dye stain it relatively dark (trans-tint vintage maple), via spray, then top with Arm-R-Seal. I used TB2 for the glue, and am fearing that the thin line of glue would not take the dye / topcoats? was contemplating trying to scratch the glue down a little, then add a little epoxy which i believe would take the dye a whole lot better. Worth the effort? Or other ideas? The client is me and I’m in no rush, so will do what needs to be done if it will help.

I’d wipe it down with some naptha or mineral spirits and see if glue shows up before I did anything else.

Thanks Roger. You can see the glue while the boards are dry, and also with a water spritz. Its a dark line at the seam

I think I would try filling the void with glue and sanding,while glue is still wet. If you can get enough saw dust mixed with the glue it may blend. Short of that if your top is wide enough, rip out joint and try again.

It’s very hard to conceal something like that, consider ripping it apart right through the seam and regluing. This would probably cost you 1/4” or so in width after jointing, so it may not be possible.

I would either rip the seam and rejoins for a good fit. Or, lay an inlay strip of contrasting wood (make it a feature) or a subtle inlay that blends but stands out. I would not try to fill the gap to hide it with glue or any other filler.
