12 string compensated saddle

[Antonio Cotichini]

The question is simple: How would you, wise and expert Magicians, manage to make a (more or less) perfect compensated bone saddle for a 12 string dred? I went to this page http:// www lutherie.net/saddle_angle.html and scrolling down I find the profile that is theoretically perfect for a 6 string. But alternating a smaller diameter string with a fatter one, it would be a sort of very narrow saw theet. Should I reach a compromise or the hardest way is the one?

THE 6 S AND 12 S SADDLE SHOULD BE THE SAME AS FAR AS I AM CONCERNED

[Jeffrey L. Suits]

Need to use a wider saddle. The octave G string will have a break point ahead of the high E string(s), and the difference between the Low Es can be 3/16".

[Antonio Cotichini]

This is the way I did it on my 12. But what I was asking is: on the A, D and G strings should there be a different break point from the slim and the fat string of the same note?

[Russell Vance]

Seeing as the fat and skinny strings have different mechanical properties (I didn't say tensions because the engineering geeks will complain), I guess you would expect them to intonate differently at different (relative) places on the fret board and that a different compensation is required. Whether you have a strobe and the rest of your life to dedicate to these 12 string works of the Devil is something we will see when we next hear from you Antonio! Good luck mate.

i agree with rusty get to work and tell us what you think R , bone is $2 a blank plow away plow men and philosophers each must know there part to mold a new reality _ _ _ _ .

[Mike Kolb]

huh?

[Antonio Cotichini]

So, once I compensate for the low E (as I did), all the rest is as regular as for a 6 string guitar.
Thanks guys.
No strobe, Rusty, and not all that time remains!
Paul, for sure my English is not good enough, what you said is a bit cryptic, but I see it's the same for Mike.
It isn't a problem of money, it's just theory.

Back to the drawing board Antonio...looks like your g,d,a is out of sync.The uncompensatated sound of octave based compensated saddles is referred to as "choing" by Andy Irvine.The less choing, the closer you are to being in tune.Instead of striving for perfection go for correction.Actually looks like you did a good job! Post a sound bite for us.

[Antonio Cotichini]

I'd gladly do, Tim, if I'd be able. My head and hands are better suited for wood and bone than for recording and internet. The octave sounds in tune to my ear and Korg CA-40. Just some minor buzzing, due to the low action and a full step down-tuning, that I don't dislike too much on a 12 string.
If I'll learn how to do I'll send a sample of sound.
Re-thanks everybody.
