Titebond 1, 2, or 3. Forget Gorilla Glue. I used Titebond 1 when I made my last box, worked fine. I think the different versions have different cure times.I have not tried it out, yet. The box is still in the making, waiting on carpet and a free day from work/school. I might have to add glue to the joints now because i skipped that step. Another thing do you guys think it would be okay for the screws to be take out at this point to add glue? What glue is best for this? gorilla glue?
