Re: Acoustical effect of back woods

I think I follow...

So it’s a bit like saying, in order to see if you can tell the difference between Granny Smiths and red delicious (blindfolded perhaps), then first let’s make sure you can tell the difference between apples and bananas?

Re: Acoustical effect of back woods

It’s an interesting topic, and I’m curious Peter; what would be the control that the study design omitted? A control group, in my high-school level understanding of science, is the experiment run the exact same way but without the variable that is being tested. Here the variable is back wood species...

Re: Falbo Intension Bridge

Maybe it amounts to the same thing... like if I take a wheel off my bi-cycle it's now a uni-cycle... if you phase align the two poles of a dipole then you have a monopole...?

Re: Falbo Intension Bridge

I have another probably quite dumb question. When I wire my lounge speakers wrong, they're 'out of phase', but this refers to the polarity of the wires. It does mean that as one speaker moves forward, the other moves back (assuming perfect amp output linearity etc). However, phase linearity of the s...

Re: Falbo Intension Bridge

I was always under the impression from my old beaters that the top's distortion over time was mainly a buckling in front of the bridge from the mostly linear tension of the strings. The smaller rotational force on the bridge ensured that the buckling was a dip rather than a bulge. If you cancel the ...

Re: How much time does it take you to build an Acoustic?

Judging by what everyone is saying, the answer that you give to this question seems to be related to the answer that you would give to a previous thread, "what is handmade?" The more your guitars are 'handmade', the more time they take, perhaps. So maybe when you are asked, "are your guitars handmad...

That's a great idea; the Mile End Guitar Shop in Montreal are doing a similar thing I think. It might be worth getting in touch to see how they work it. https://www.facebook.com/pages/Mile-End ... 4922310026

Re: Thinning boards

Two other advantages of hand planing: it is quiet, so you can listen to the radio while you work; and it creates no dust, just a pile of shavings.

Really nice, cool to see such a good combination of the 'purfling' rosette with the 'inlaid pretty veneer' rosette. (for want of a better term)

Re: grain thru binding

I've also been thinking about this lately - thinking only, so my comments are only theoretical! But if you thickness the sides to 2mm, then cut the bindings off with a blade whose kerf matches the width of the purfling, then continue to thickness the sides down to 1.5mm, then you will only need to m...

Stella Guitar

Not the old-time guitar brand, but a guitar I made for my daughter Stella! The rosette is based on 'starburst' clocks from the mid-century modern era. The top is kahikatea, sides and neck are recycled mahogany bedheads, bridge is totara, binding is kauri and the headstock veneer is Australian lancew...

Re: String breakage

Since it's the strings in the middle that are breaking, I wonder if the radius on the saddle is too small for his right hand style. Perhaps flattening the radius would help to spread the load, so to speak, over all six strings. ..or will that mean he starts breaking all six? :)

Steel Stain on Skin

I have a bit of a strange question – I think it belongs in H&S, if it belongs anywhere - when using cabinet scrapers for any length of time I get a black stain on my fingertips! Apart from looking a bit alarming it doesn’t seem to irritate my skin or anything, and although it does make me wary of to...
