Furniture and Furnishings - chair repair help

I have an 60's scandinavian chair that has two loose joints. I'd like to re-glue them together, but the problem is I can't pull the joints completely apart. They will separate only about 1/2" but I'm afraid if I apply anymore pressure I'll crack the joint. How can I take the chair apart with out damaging it? Is there a way to get glue into the joint without taking it completely apart? Any help would be greatly appreciated.

It is possible to inject some glue into the joint with a syringe and clamp it 'til it sets. How well this works will depend upon the tightness of the joint. If it is wallowed out, it won't work because glue is not suited for filling voids.

You can pick a syringe at local drug store. Try yellow glue, such as: Titebond or Elmer's.

Hope this helps.

Thanks Chris,
I finally managed to separate the pieces. I just purchased gorilla-glue (the guy at the hardware store recommended it) Is it alright to use?
Thanks, Clint

Be careful with the Gorilla Glue
It really expands when drying and can mess up your work if not careful
TiteBond or Elmers Wood is usually a better choice for wood chairs
But you don't have to go back to the store, you can use it
Just remember it really expands as it dries so don't goob it on
If some squeezes out and it's not too much, you're almost better off letting it dry and chiseling it off later
It really is a great glue
I use it often repairing furniture
Oh Yeah, have some thinner on hand as it does NOT clean up with soap and water
Denatured alcohol is what they suggest I believe
(that's prolly why I chisel it off later ha ha)
