Yes, you're quite correct there Adrian. Of course the dilemma is that there are so many different string types, gauges, and setups that it is impossible to display a universal final pitch chart...

Here you go - I played with a few numbers, and this seemed to fit reasonably well -
14.95 base scale using a 17.735 divisor will yield the equivalent of a 15" scale using 17.817. Add a nut...
I'd say that's a very good guess, or at least I say that because it's the best theory I've been able to come up with so far as well. ;) Whatever the the original motive for this formula, it does not...
Mandolagirl's approach in her post I would say is a very good and pragmatic one. Though I am more often heard criticizing them than recommending, I'm really not against compensated nuts. My cringing...
When playing on a modern 12TET spaced board, I find most intonation complaints tend to stem from two common sources. First is poor setup, particularly at the nut. Virtually no factory instrument will...
There's nothing about spacing on old Gibson mandolins worthy of being considered beneficial or as an improvement over standard spacing. I've studied their fret spacing a great deal, and have yet to...
Good to hear they're finally in, I just placed an order a week or two ago and they still weren't in yet - must have just hit the shelves.
I have a 1917-ish A-2 in the shop right now - I'll try to...
I try to spend at least a week or two every year up on Lake Superior picking agates (though I inevitably end up keeping a lot of chert and jasper as well). I'd love to use some agates for inlay, but...
I understand your point, but I would just say that the initial question to bring this all up was not "will this bridge sound good on my instrument", but more in line with "are the claims as to why...
It seems as though the claims of the Brekke bridge design could be tested in a simplified and comparative way pretty easily. Here's a little makeshift monochord I threw together for some of my own...
Okay, I get it now.
I was right, but I was only thinking about standing harmonic waves, driven sharply in the center of the string, in which case you do end up with a square wave exactly as I was...
Looks like I'll skip the second edition and wait for the 3rd - thanks for letting us know! (Edit: -oops, I guess it's not a new edition of Physics of Musical Instruments, but a new book entirely - I...
@draino,
The string at rest is the point of minimum longitudinal force, and deflection in either direction will only increase that force relative to neutral. As said about transverse forces in...
Net force, yes, only positive forces exist here. A pulse however, must be a change in force, in this case considering the force of the string at rest to be neutral. If a string exerted a force of of...
Agreed that we can leave it there for now, but there are still a number of points to the idea that the bridge sees only square pulses (when considering only transverse force) that just don't add up...
The idea is that if a string moves in a sinusoidal wave, that the energy imparted to the bridge comes in the form of square pulses. Force downward on the bridge would switch instantaneously from 1...
I know this thread has taken many tangents, but to go back to Fletcher/Rossing's square wave force brought up by Dave Cohen. I have looked at those particular charts and formulas many times over the...
Or pp 209-212 in the 1st edition (haven't got around to getting the 2nd edition yet).
Good luck getting universal agreement there. Continuity in terminology is going to be what's hard to find. ;)
There is rift and quartered as a mill operator may describe (which I believe to be...
So I guess it could be summed up as "vendor-specific terminology".
I think those folks you linked to are the only ones who have ever used that term. Sounds like a term of their own making, or perhaps one used in certain locales and circles that I am unaware of.
...
Spiral cut? Where did you hear of that?
Spiral cut refers either to a type of cutting bit or to honey glazed ham. I've never heard of anyone using that term for a type of wood cut though. The...
Perhaps Dave will come along to clarify in his own words, but I believe the key word in that statement is "modes", as in forms of wave propagation. Yes, energy is transfered from the strings through...
There is certainly some truth in that they will transmit and reflect vibrations differently (obviously) as energy is transfered from the string to the top. Yes, energy will of course be transferred...
Take it to an instrument repair shop, not a store. On rare occasions a store may actually have a good repair tech, but this is fairly rare.
I see no reason to assume it's unfixable - it may just...
