Truss rod? Glue in?

[SnowManSnow]

Hey guys.
I've read different things in different places on this topic.
Should I epoxy the ends of my truss rods in the neck?
Thanks

I think it might depend on the rod you use...

I see.
I believe I have a double action hot rod from strew mac.

Yikes! Epoxying the ends would render it a no-action truss rod. My understanding of that style of rod is that you shouldn't glue it in at all. Just fit the channel snug so that it doesn't rattle, and be conservative with your glue for the fingerboard, being careful not to get the glue in the threads.

Yeah no need to glue those it. Just fit the ends in nice and tight.

Martin recommends continuous gluing of their plastic-wrapped, two-way adjustable truss rods.

I know that most other sources say gluing is not necessary, but, I think continuous gluing would provide a more uniform pressure on the fret board (when adjusting the rod to reduce neck action). Unglued, the rod would concentrate the pressure on the middle of the neck (5th-7th frets).

The plastic wrap allows the rods to "move" as much as needed during tension/compression lengthening/shortening.

Two-way rods vary in their design, construction, installation and use. Many of them, such as the HotRod from Stewart MacDonald, require at least one full length component to rotate freely during adjustment.

Depending on the adhesive, gluing the entire HotRod could absolutely mess it up and render it useless. Note that StewMac suggests bathtub sealant caulk only - to keep it from rattling. Caulk is not glue and won't seize the rod.

As with all guitar building and repair techniques, it pays to be careful where you get your instruction and advice.

No two rod system I am aware of requires being a affixed as long as it fits well enough to stay put, and more importantly yet, has little to no vertical clearance in its slot.

Thanks guys. I'm still learning and the "methods"vary so much out there

I make my own two way truss rods and never pot them in place

So long as the tension beam is covered in a plastic to prevent subsequent possible vibration, then all is good.

Single action truss rods with a welded anchor, I pot the anchor in the neck.

How do you make them? I'm thinking I need to make a custom one for a short scale tenor guitar I am building right now. The only instructions I have are from the Cumpiano book, I'm sure there is plenty via Internet search but I'm curious of your method.

Nice!

I don't have that tooling so I'll have to stick with round stock, but that looks great thanks for sharing.
