Just so you know, these chairs where given to us from a buddy that was leaving the country, they are crap, made in some factory somewhere, I'd be sitting on wooden boxes before I'd PAY for these things
The basic problem is that the glue is holding the chairs together, the angles on the mortise and tenons are all out by a fair bit. If you dry fit everything, it does not stay together.
I've fixed these chairs a few times now, the glue in them is dried out, rock hard, dunno what it is, looks almost like CA glue
Anyways, I came down for breakfast and saw this..........
My youngest daughter, Mizuki, of the micro crane fame, was sitting on it when it let go, she is all of 80 lbs soaking wet.
I cleaned all the glue I could off the tenons, and out of the mortises, then I did this to the legs..........
not pretty, but I figure when I bang it home, it might have a better chance of staying put. I used 5 minute epoxy, as the only other chair that is still hanging together I fixed with 5 minute epoxy.
There it is, all nice and snug
I dated it on the bottom, just to see how long it lasts
