Re: Domestic hardwoods for wooden tailpieces?

I guess in part I was wondering what qualities a piece of wood would need to be up to the stress. I don't know if tensile strength is measurable (or meaningful) when talking about wood, or if there's a toughness indicator, or if weight or grain quality make any difference.

Sorry, for an archtop guitar, hung from a Sacconi-type loop.

Domestic hardwoods for wooden tailpieces?

Are woods like maple, walnut, or cherry structurally sound enough for use as wooden tailpieces? Has anyone used them or others in a build?

Re: White colored marking pencil, pen???

I've tried both white and silver colored pencils, but the lead is too soft, so it's hard to get a good, crisp line. Now I just lay down some tape and mark on the tape. 3M makes a low-tack white tape. The low-tack can be problematic sometimes, so I often just use drafting or masking tape.

Re: chip/dust collector for Safe-T-Planer

I'm glad you realized I was kidding.

But your point about the quality or suitability of one type of plastic vs another is well-taken.

Re: chip/dust collector for Safe-T-Planer

I'm not a big fan of Thai food. I'm thinking of substituting a potato salad container from the deli, and wonder if anyone has tried something similar?

soundhole placement

ok obviously there are any number of factors at work here, but are there any guidelines with respect to f-hole placement? What happens as you place the holes near or further away from the rims? Or nearer or further away from the braces? The only thing I've ever found was in the Benedetto book, where...

Re: New bridge made a huge difference

Paco: Sorry if I wasn't clear. I replaced the bridge FOOT with spruce. Other than that it's the same as the one pictured in the first post, including the bone saddle.

Re: Soundhole (f-hole) size

I just rechecked my figures and I was wrong. There appear to be barely 3 sq inches of opening per New Yorker f-hole, and roughly 14.5" of perimeter. So the hydraulic diameter PER f-hole would be (2.82 * 4)/14.5 = 0.78". The 1.55"" I stated before was the COMBINED value. How likely is THAT to be true...

Re: Soundhole (f-hole) size

I did a rough measurement of the New Yorker soundhole in the link that Dave included in his post above, and given the formula he gave for finding the hydraulic diameter of a complex shape, each the New Yorker f-hole would ROUGHLY have the hydraulic diameter of 1.55".

Re: New bridge made a huge difference

That IS a pretty lame descriptor I guess, but I don't know as any other term I might use would be any better. I sort of lack the proper vocabulary (and experience), and that doesn't help. By comparison, the sound was a bit more muted before---almost like the tone control on an electric had been dial...

Re: New bridge made a huge difference

I just swapped out the white oak base pictured above with spruce. Same shape and dimensions. 11g in weight, and it is again a noticeable improvement. Not sure what the negatives would be w/respect to using spruce, but for now I'm liking the difference.

Re: Soundhole (f-hole) size

ok I'm going to go ahead and admit this right up front---I understand very little of what either of you just said. Don't get me wrong---I appreciate your thoughtful and generous answers. I just don't understand them. But I'll keep trying. How are you measuring resonances and frequencies and such? Ma...

Re: Soundhole (f-hole) size

What got me wondering was---I covered over completely my f-holes with low-tack painter's tape. Just to see. It seemed that this had the effect of thinning out the sound, almost as if what I was hearing was more the sound of the strings. Not sure if this had the effect of damping, or trapping, or can...

Soundhole (f-hole) size

Bear with me here. These questions are not all strictly speaking related to each other. And I know this type of question comes up periodically... What would be the effect of sizing the combined area of two f-holes with that of a (more or less) standard 4" round soundhole (12.5 sq in of opening)? Tak...

Re: Tools for checking intonation?

Thanks Mario. I guess the pickup eliminates extraneous noise from the equation. That makes sense. And it's common for the readouts of cents on these things to be somewhat "fluid"---sort of flipping around an 8 or 10 cent range, then pausing for a microsecond (assuming the cat doesn't meow and throws...
