I am a big user of Super Glue in my shop, but it has pitfalls on stock work. I just did a forearm on a inexpensive Hunter Arms gun. Screw holding the iron had stripped, Drilled the punky wood out let in a dowel super gluing it.

Super glue found a crack that was invisible and ran outside on the finish drying in a few seconds. Stuff is so hard only a complete re-finish will cure the unsightly run.

Better to use something that has a longer working time. 2 part epoxy is best, runs out of the crack you have time to clean it up before it sets.
