I finished a box made out of 1/4″ red oak last week. I had put one coat of finish on the out side of the box and then I ran out of time to work on it. During that time where I live has gone through a few weather changes and now the bottom of the box is pulling free from one corner. I used Tightbond II and had squeeze out all the way around. The box stayed clamped up for a couple of hours before I took them off.
I am fairly sure it is the weather change and the fact that I had not gotten any finish on the inside of the box that is making this happen.
I am open to suggestions on how to fix this little issue. Up to and including removing the bottom and replacing it. I am kind of leaving that to a last resort.
Thanks in advance
MichaelI don’t know–I have always just given Tightbond II a good 24 hours undisturbed to make sure it cures fully. On the other hand, I’ll use Gorilla Glue for wood and only give it 1-2 hours before feeling comfortable doing some light work on the piece.
Did you make sure the base was flush/flat all the way around before mounting it to to the base?
Other than the last resort, I’m not sure how effective other strategies would be–you could try to force some glue into the separation and re-clamp the whole thing but I would worry about the obvious risk of re-separation and also messing up the finish you have already applied. How difficult would it be to remove the top from the base, re-sand everything clean/smooth and try again? I imagine that would probably ensure the highest-quality final project but I guess it’s up to you to determine that.
14 November 2016 at 10:26 pm #142412I am with dbockel2 on the 24 hours for glued surfaces. You could use some epoxy made for wood also. It all depends on how much pressure you need to put on it to close the gap.
14 November 2016 at 10:28 pm #142413I did make sure it sat flush before I did the glue up. I am starting to think it is the piece of wood that is just going to be a problem. It was cupped when I got it and I worked it till it was flat. I think with the changes in humidity the wood is trying to cup again.
The fun will be getting it back apart with out messing up anything else.
14 November 2016 at 11:09 pm #142414I can close it using a clamp but not with hand pressure. So my concern would be it pulling apart even if I used epoxy. I tried superglue just on the off chance it would work. It didn’t..
I am not sure I could get epoxy into the gap so it is looking like I am going to try to pull it apart.
On the plus side the finish is very forgiving and once the box is put back together it should be perfect15 November 2016 at 3:51 pm #142418Took it apart planed the bottom flat again. Glued up and its in the clamps again. I am going to try to get some finish on it asap once it comes out of the clamps
Thanks
Michael16 November 2016 at 1:14 pm #142450One thing not discussed is that glue can go BAD. There is a shelf life. If it is more than a year old, toss it and get new stuff…
16 November 2016 at 1:31 pm #142451Thanks Brett
I had not thought of that and it was the last of a bottle.
I used a new bottle for the re-glue. I am going to take the clamps off in a bit and see how it is.
Thanks everyone for your suggestions
