Another type of glue gun is the glue injector, similar to a medical hypodermic syringe but made of plastic. The injector enables you to injcct glue deep into a loose joint in order to fix the joint without taking the furniture apart. In some cases, you can insert the long, thin tube of the injector directly into the loose joint. In others, you must drill a '/¡6-inch hole near the joint to gain access. The glue injector does a good job on temporary repairs, but once furniture joints have started to loosen it is inevitable that the piece will have to be taken apart and completely reglued.
