Hello fellow LJs, I need some help dissolving some glue on a chair that I have to repair. The chair is a factory made item, probably made in the U.S.A., around thirty five years ago. The glue is a hardened red stuff and was used to glue the angle bracing to the front to side rails. The bracing and rails have been machined with interlocking grooves.

I’ve googled, and all I come up with is vinegar. I don’t want to have to refinish the chair because it is part of a dinnig room set. The rest of the cahirs were easy to knock apart, these people appeared to be stingy with their glue. This is the last chair and only two of the four braces remain. Thanks y’all for any ideas or input I can get here.

Might be plastic resin glue. I think maybe acetone or lacquer thinner
might dissolve it. I never tried though so who knows.

Hide glue usually is brown as it ages. It can be dissolved with
heat and steam. Try to get a soldering iron or hot knife in
there and see if the glue liquifies with direct heat.

I was using a flatbar and a 16oz. hammer to pop the other braces out, worked well. Thomas, I used a chisel to pry one out of this chair and that worked but only on one brace. Don’t want to skin up the finish. I used a wedge but it started feeling kinda weird, like it wanted to split in a way I don’t want. You know, I might go try a clamp to the opposite corner, constant pressure and some heat on the glue. thanks David.

They are wooblely lose. The customer that brought then to my told me her boys tend to sit in them on the back two legs a lot. No mortise and tenon, just dowels. Most of them are dry, I can pull them out with my fingers. Like I mentioned above the factory that made them was stingy with the glue, not much used anywhere. And it’s some kind of red stuff that dries hard and looks like wax. Most of the places where the pieces butt together had the stain seep in between the joints compomising the glue. They’re pretty but they are mass produced second rate chairs. Not a job that I really wanted but the lady that owns them is a friend of my mother’s for the last 60+ years and has known me for all of my time here on this planet. She’s an old family friend and a good customer I kinda had to fix them.
