I am in the process of repairing the forend of an o/u shotgun that had split down the middle and then "repaired" by the owner. I had the gun originally to fix an intermittent firing issue but when test firing that repair, the forend came apart after the 8th shot. So I have carefully picked away all the old glue, drilled both sides for invisible cross pins (hardwood dowels) and am ready to glue and clamp. The wood is not oil soaked. In the past I have used the Brownells AccraGlas, 24 hour epoxy, super glue, Gorilla Glue and Titebond. All have seemed to work okay but this one worries me since it has already failed. When it failed, probably from a poor fit during the repair, the glue stuck to one side and took a thin veneer of wood from the other side. While I was careful picking the unknown glue from the wood, I also had to remove some wood as the glue had stuck securely. When the two pieces are clamped together, there is the slightest gap due to missing wood so whatever glue is used it will need to able to fill a slight gap and still function as glue. Had I continued the job without asking here, I would have gone with the long cure time epoxy with added dye. I do realize that there be many new kinds of adhesives that I am not aware of and wonder if there is something better? Thanks for any comments!
