Wooden chair repair

Considering the damage you could do to yourself if it "let go" when you sat down on it, I'd be inclined to toss it out and get a new one.

throw out the chair.. your back is worth more than a broken chair... dont believer me?? just sit in it and fall over backwards and see how long it takes for you back to heal....

According to Dan Hartung :

You can do virtually anything with the proper glue as long as the wood itself still reasonably solid, and you spend enough time piecing things back together. Modern glues (especially good carpenters glues or regular epoxies, not "5 minute" per-se) are stronger than the wood itself when used right.

Whether the result is "acceptable" is going to depend on a lot of things. Like, how much is the chair really worth to you? Will you manage to avoid abuse beyond its capability? How well built was it in the first place?

It's rarely something that anyone else can judge for you sight-unseen.

We've had some chairs we've bothered repairing only because the teddy bears who use them have promised to treat them _very_ gently. One bear refused, and he has to sit on the floor instead.

If it's otherwise reasonably sound and has some redeeming characteristics, we usually repair it. But, turning new legs, for example, may be a bit beyond what you're interested in doing.

A badly-split leg on a chair is probably beyond saving, unless you're going to restrict it to light duty, or spend the time to use dowels or make a new leg.
