I seem that I just don't know enough about this. I wasn't thinking that the rod would need to be double action rods or how much hardware that would put inside the neck. After reading your post I see that this would be a major pain to set up without something like your caul.<br />
<br />
I have to admit that I'm intrigued by ideas like this but I can't see it having any real effect on me. I doubt I will ever have a CNC machine and I really doubt I could ever do this by hand.<br />

<br />
Another thing that crossed my mind while reading the article was to wonder how susceptible this would be to environmental changes. I was think about a book I read which mentioned the problems exhibited by great violins as they are taken from place to place for concerts.<br />

Thanks for adjusting my thinking on the double truss rod's, Rusty.<br />

Yes, it was something that crossed my mind - however, to get a positive relief and a negative (tending) relief by way of a dual truss rod setup (like the demon Rickenbacker which use it for graduating the positive relief on their necks - a current thread) you would probably need to install double acting rods if you were starting out with a flat neck - this accounts for the fact that the neck is not spaghetti and will need to be forced to assume the gradient required.

Yes, it was something that crossed my mind - however, to get a positive relief and a negative (tending) relief by way of a dual truss rod setup (like the demon Rickenbacker which use it for graduating the positive relief on their necks - a current thread) you would probably need to install double acting rods if you were starting out with a flat neck - this accounts for the fact that the neck is not spaghetti and will need to be forced to assume the gradient required. The weight and tone problems with having this much iron work in the neck becomes an issue.<br />
<br />
However; if one was to construct a neck with positive relief in the quiescent state and then use two (side by side) one way rods to graduate the degree of (relative) negative relief you could achieve the same thing providing the neck was flexible enough. We have used a pre-stressed aluminum caul and carbon fiber reinforcements to dial in set relief when doing some necks, so that is doable relatively easily. The rest is a crap shoot but it would probably work.<br />
<br />
Being an electric geetar sort of bloke, I probably haven't thought this through well, please feel free to tell me, and I'll probably blow the research and development money for this on beer anyway. Have a good weekend, Rusty. Russell,

I've never worked on one but I was thinking about the double truss rod necks that some 12 string guitars have and wondering if this system would do what he was writing about?<br />

Bob,<br />
I have no issue with you having another site, something I think I stated clearly enough. I don't have any issue with you being here or even a post introducing your site. I just pointed out that the combination of you creating a post here which redirects the reader to your site followed by your invitation to the first responder to take his comments there, "smacks a bit of spamming to me". I didn’t say it was spam, but I believe it is leans that direction.<br />

<br />
We have all, from time to time posted links to other sites some of those links were made by the owners of that site. In every case I can think of it was in answer to a question while it seems to me that the main point here is to generate interest in your new site. In my thinking this, pretty much amounts to an advertisement.<br />
<br />
Can you see how I might think this as a bit like spam?<br />
<br />
I didn't mind taking a look at your site. I found the article interesting and I look forward to more of the same. It is just that I would have looked at your site just as quickly if you had simply posted an announcement of its activation and wouldn't have though anything about it.<br />

Seems to me that even with his end result with string tension (1/64" differential)it would mean that if you gave the treble E 5 thou relief you end up with 20 thou on the low E<br />
Way too much relief for my taste, you end up with high strings mid board and then climbing up out of the hollow as you get higher<br />

Seems to me that it makes sense if the neck in question is subject to the forces presupposed (more force on the treble side of the board) and therein lies the issue for me: some necks twist this way undoubtably, but the majority do…

<br />
Similarly, in the electric guitar world there is a proliferation of hybrid string configurations (light tops heavy bottoms, 10 - 52, 11- 54, 10 -70, different core to wrap ratios etc) which do not conform to this preposition or tend to ameliorate the effect. This is coupled with the widespread use of stiff maple necks and carbon fibre reinforced necks which also resist or negate the asymetrical twist in question.<br />
<br />
This is not to be a naysayer, it simply says that this information, in it's unqualified form, is relatively useless and any attempt to implement it without determining the pathology of an individual stable neck is likely to cause a problem rather than fix it. But, obviously, for a neck that does have the problem of treble side twist this form of manual or machine manipulation would appear to be a useful tool in sorting the action.

I wondered about that too Greg. I also have some reservations about his thoughts on the amplitude of a strings motion. From what I understand the direction of string vibration is pretty dependent upon the initial stroke. It seems to me that the strings tend to move more side to side than up and down so I would think that most of the compensation for the greater motion of lower strings would need to be in spacing between string, not distance from the fingerboard. Am I thinking wrong about…

Interesting article, Bob, but I must say that you presenting it here then requesting that Greg make his comments on your site smacks a bit of Spamming to me. In my opinion it would be better to request permission from Frank before promoting your own site on his.<br />
<br />
I'm not opposed to having more sites for Luthiers, I just think that a general announcement may have been a better approach.<br />
