Epoxy vs CA/Ron N.

Too general, too binary, too dismissive. Needs qualifiers.

Like I said - too general. I don't trust CA at all for action part repairs 
or general woodworking joinery, and don't carry it for field service. Why? 
Because my experience also is that it won't hold up under tension as a 
means of keeping parts together. Soaking into wood (making fiber reinforced 
plastic), to provide support for bridge pins or even tuning pins is an 
entirely different world. The forces are different, the requirements are 
different, and the penalties for the CA "letting go" are vastly different. 
Just because someone uses a glue in a manner that is doomed to failure 
doesn't make the glue bad.

Right - or used in an improper manner, which doesn't make the glue bad, 
just the choice of usage. An orchid in a pansy patch is a weed. I hope this 
clears up my position concerning your post. <G>
