Fixing a couch: Inlays for torn out threaded insertsWe bought this couch used two years ago. It's a high quality brand of couch. Some months after our move to Fredericton, I noticed there was a gap between the leg on the left side and the part that goes across the bottom front, and the joints on the left side were opening up too! Time to fix it.
Examining this, the threaded inserts that the threaded rod studs go into had partly turn out of the wood, breaking quite a bit of the wood out on either side. So I couldn't just fix it by gluing the threaded insert back in.
For the dowel joints, I had been thinking of pulling them together using pocket hole screws, but the dowel joints only required some tapping to open up completely! So I might as well re-glue the joints properly.
I also marked a circle centered around the hole for the insert for locating the new hole after the repair.
By the looks of this grey glue, a previous crude attempt had been made to glue the loose dowel joints back together, so the dowels had come loose before we bought the couch. Though I'm pretty sure the torn threaded insert came from the movers.
I got tired of scraping it with a chisel, and thought of using a sander, but the glue might gum up the sand paper. So cut it with the table saw, cutting probably about 0.1 mm of the wood off too.
To fix the insert holes, I needed to remove all the wood that had cracked from the torn out inserts. I used my slot mortiser to carve out a rectangular area around the cracked part.
I rounded the corners to match the hole on my edge belt sander
I found a bolt of the right size to fit in the insert, then used a socket to drive the bolt and insert in, then backed out the bolt.
But I couldn't get the joints to all close properly. I ended up prying it apart again before the glue set and drilling the dowel holes slightly deeper, then put it back together, but I couldn't get all the gaps to fully close at the same time. It just didn't fit perfectly
After I glued it, I had a look at the other side and saw some small gaps there as well. This whole side frame probably never went together quite right in the first place. Kind of disappointing for a fancy couch like this.
I also added some wood screws to the other side. Hopefully, that will allow the couch to better survive another move, though we aren't planning on moving any time soon!
