Speakin of do-it-yourself truss rods, i have question

[rdhbass]

I have been thinking of making my own truss rod on my next bass and heard somewhere of someone simply getting a threaded rod, anchoring it at the neck's end so it won't move (running it through 1/4" steel stock with hole drilled in it anchored somehow), and finding a matching nut for the adjusting end. Will this work, sounds simple enough. This version is not like the gibson version that is bent down at the middle of truss rod..or do i need to do this....

okay..bump... Has anyone made their own truss rod with a single threaded rod and anchor in the neck.. thank you.

Standard single truss rods use a curved channel. The curve is oriented so that when tension is put on the rod, this puts pressure on the center of the curve, bending the neck- basically the rod "tries to straighten out the channel."

It is also possible to have a straight rod in a straight channel, and have it serve to produce backbow, to counter the frontbow produced by the string pull. But you have to put the rod close to the back of the neck for its full length, in order to guarantee that is is on the opposite side of the neutral plane of bending from the strings. It is also possible that in this arrangement you will need more tension on the rod than if it were in a curved channel, and this greater tension increases the possibility that you will induce an s-curve in the neck.
