Stationary Truss Rod

[Phil Delpierre]

Generally when I build a 4 String, I  put a steel bar in the neck, back-fill with epoxy, and top with a fretboard.  What do folks think about using Liquid Nails instead of epoxy for this?  I'm curious if anyone has tried it and if it would be stable, or if it would impact sound in a negative way.

Could deaden the sound a wee bit, and no I have not tried it I use epoxy to for my square tress rods in my six stringer

Go with epoxy. I put fixed steel in some of my necks, and wouldn't use anything except a good long-cure (ie not rapid set) epoxy. All the "liquid nails" type adhesives I've come across have poor bonding strength compared with epoxy, set quite soft and are designed to bridge large gaps..so I suspect they may a lot of bulk filler in them. Not the stuff to use for the close tolerance, high strength application of a guitar neck.

i dont think liquid nails would be a problem for a few reasons 1 it cures out pretty hard so its not gonna absorb much energy 2 you have the fret board between it and the strings so it would have that insulation.

btw it would cost a bit more but they make carbon fiber rods for inserting in a guitar neck that would decress the wieght of the neck a lot over steel. but i really dont thing either is nessasary i have a four string strung with the top 4 strings out of a pack of 10's its a maple neck with a oak fret board and has almost no relief to it.
