RE: Devcon Blue Threadlocker
You know, I've been thinking about this one. Threadlocker is meant to be used in very thin layers, like the near-microscopic gap between the threads of a bolt and a nut. We're talking about mere thousandths of an inch here. I don't think large gobs will ever cure, so you can't judge the state of the threadlocker where it counts by the stuff that squeezed out when you put the parts together. Even with CA, large gobs take weeks to cure on their own. Otherwise, the bottle would just turn into a useless solid mass within an hour of its initial manufacture.
The fit of the parts has to be close, with little or no perceptible "wiggle." You can't glue a 1/4" nut on a 1/8" shaft, for example.
