Super glue and Krazy glue are all basicly the same cyanoacrylate adhesive. The pen turners are just using glue for a finish. Lets just hope they let the glue dry before they write something. :laughing: As far as putting ca glue on threaded wood to strengthing it you have to think about what wood is. If you looked at wood under a microscope it is like a cluster of drinking straws bonded together in a sheet. If the wood was fraid and you filled the straws with ca glue and let it harden it makes the fibers more rigid. The only problem I can think of is if the wood was sealed with ca glue you wouldn't be able to stain it.
