I tried my hand at CAD...Ok so I'll leave this up to the pro's like Watkins, but
for those of you who might be interested in this, here is my bridge design
with measurements.

Cool John, everyone's got to start somewhere.

How long did that take you and what program?

Well done, I'm sure it sounds better on a piece of wood though

I like it!!! It is very similar to mine.

Rod,

Used Turbo Cad for Mac. Took me about 1 hour.

Joe,

Yup..I basically copied Bourgeois bridge, and then made some changes to it.
I have been using this design for years now I just decided to try to CAD it
out...

Hey that's pretty good John if your just staring out with Cad software.

I too like the design, nice and simple with just a hint of flare (the wing ends)

John, why do you want to vary the afterlength like that? Do you think the
effect is negligable? I guess I would be afraid that the D and G would
sound...floppier for lack of a better word. The angle is less over the saddle
for the D and G and I think that effects downward pressure thus effecting
how "loose" the string feels.

So long as there is sufficient break angle I think the effect is negligible
(mine is quite tame when compared to..say Ryan for example), and if it
were ever a problem (I've built 140 guitars in my name and the problem
you mention has never reared it's head for me) you can always cut, or
angle the slot close to the saddle to effectively compensate for the
longer/shallower break angle, and this would make it very easy to make
all the break angles the same. You also have to take into account the
arching of the top of the saddle helps to offset this as well.

The main reason why I do it is because I think it looks elegant, and it also
makes it to where all the string holes are not in line therefore reducing
the chance of bridge plate cracking.John Mayes39094.9935069444

John...looks good.

Okay John, I guess it has a negligable effect as you say. I just looked at
Ryan's guitars and see what you mean. I don't get out much playing custom
guitars, I would like to play a Ryan and a Mayes for that matter. Maybe I
could make it to one of the big festivals some time.

John,
    That looks good. I've always liked your bridge shape alon with all of the
design aspects of your guitars. Turbo CAD is a powerful program. I have it
loaded into my G5, but haven't put it into my MacBook yet.

    I alo have a version of BobCAD that seems to work well for vitual
modeling.

    Keep up the great work and enjoy getting into that software.

Regards,
Kevin Gallagher/Omega Guitars
