Re: Is this considered run out? (reply)
Re: the guitar in the video. The grain on the top of the guitar from this view is diving into the center of the instrument and the grain on the bottom is rising out. The darker appearance means you are looking in to the ends of the...

Bruce: To clarify. You are just doubling the runoout percentage when talking about the visual aspect and not the structural part, right? I have always thought of the issue of runout in wood as being similar to a scarf joint. In...

I get 4.8. 2 divided by 24 equals .0833333. The cos -1 of that is 85.2. Subtract from 90 degrees and the result is 4.8 degrees.

Re: Is this considered run out? (reply)
I have an 80 year old guitar (Washburn Solo) with runout approaching 30 degrees.   I know this because I had to do some work on it and a section of top snapped over the dovetail when I removed the neck.   It's still in one piece and...

Run out is visible when the fibers are as little as a single compass degree out of alignment with the top's surface, which equals two degrees as the other half will be a degree also but in the opposite direction, but it does not become a...

Re: Is this considered run out? (reply)
Thanks for the comments. I used to never care about run out until I read an article written by Frank Ford, then I started becoming more aware and worried the top may not be a sturdy as wood without run out, especially if I spend for a 40...

A lot of reverb from the wall I think. Almost sounds like phase problems also possibly the wall of guitars behind him? I have one with run out like that. It's my favorite player, otherwise I might have some trouble lifting my shorts.

Re: Is this considered run out? (reply)
Yes, that guitar displays visible runout; something that IMO some people have got their shorts way too knotted up about of late. BTW, I think that recording sounds awful. The guitar may or may not sound good. A recording tells more...

Re: Is this considered run out? (reply)
Looks like there may be a little bit of runout, but it's hard to tell with the video. Typically, one half of the top will look lighter than the other. I have two englemann topped guitar and I've read it's more prevalent in newer...

Yes, the two halves of the top lighten or darken depending on their angle to the light.

Is this considered run out? (topic)
I am trying to learn more about wood. Is this considered run out in this video? It looks like from one angle, but when the light changes it doesn't look like there is run out. Is run out consistent in all angles of light? By the way,...
