Re: Fret Clamping Pliers

Interesting idea - thanks for passing it on. My guess is that is is designed for fretting or refretting on the neck because the lower jaw has that curved block to fit the neck shape. But my neck profile changes along the length of the neck so maybe the wood block on the bottom jaw would need to be c...

Re: Bellied up top

My first build (a cedar top OM) did the same thing, and for the same reason that you have diagnosed. I definitely over-did the scalloping on the diagonal tone bars, and probably on the X-braces in the area between the X and the bridge plate. Like yours, it sounded great (an under-braced top is reall...

It disappeared from the OLF too. Presumably Martin Taylor was asked to remove it, either by the film producers or by Gibson?

Re: Somogyi bridge

Yes, I had noticed that too. And just for the sake of any potential customers - I am happy to offer a custom made guitar, with pointy bits if desired, at about a 90% discount against Mr Somogyi’s prices. But I will admit that my guitars are probably only 10% as good. Good luck to him.

Beautiful work Rod. It reminds me of Scott Chinery’s Blue Guitars project, which I saw at the Smithsonian Institute a few years ago.

Re: Somogyi bridge

Hi Dave. I have noticed them too, and James Olson guitars have a similar bridge shape ( not quite as pointed). I had assumed it was just Ervin’s visual signature. He does pointy things on the headstock too. I can’t think of a physical reason why a wavy line on the back of the bridge wound give bette...

Re: Bolt-on neck and Upper Transverse Brace

The patent (US9520108) shows a number of variations on the invention. It looks like they went with the one labelled Figure 2, which has the full width transverse brace below the soundhole.
Yes, some field research at your local dealer is definitely in order.

Re: Bolt-on neck and Upper Transverse Brace

It has often been said that the upper bout area is structurally vulnerable in a steel string guitar. The string tension is trying to fold the instrument in half. The neck is thick, and has the truss rod rod to help resist the pressure. But the upper part of the box is weaker, and made more so by the...

Re: Heel grain orientation

Ross - I presume you are talking about a stacked heel? So, if you have a couple of offcuts from the neck blank and you are stacking them up to make a heel which will then be carved - you are asking which way to orientate them? Interesting question! (And apologies if I have completely misinterpreted)...

Re: Why a neck volute?

But getting back to Greg’s original question - why? It has sometimes been suggested that it strengthens the neck at a point of weakness.

Re: Why a neck volute?

Rod, you made me look it up and I discovered that I have been following an incorrect usage of the word volute. Martin refer to their diamond (or dart) shaped prominence on the back of the neck transition as a volute. 0E891BD9-EAB4-446C-9FE1-F2593C6AD083.jpeg I have always accepted that as the correc...

Re: Why a neck volute?

I believe that it originated with the use of a V-joint, aka Bridle Joint, or Bird's Beak joint. This is a complex form of angled mortise and tenon joint that originated with spanish guitar makers, but was also used by CF Martin in the 19th century. It looks like a huge PITA to execute, but very eleg...

You are probably already doing this - but here is what helps me. Take a guitar whose neck you like and make multiple measurements along the neck - so you can replicate these on the new one.

Rod, that looks sensational. Many individual classy touches, like the timber covered pickups and the timber knobs (did you turn those yourself?).

Re: Spotted Gum fingerboard

Regarding hardness, spotted gum has a Janka hardness score of 11kN, which is not as hard as ebony (14), but it is harder than rosewood (8) and maple (6.4), so it could probably do the job. Among Australian natives, gidgee is harder (16) and so is ironbark (14). Of all of them gidgee is my favourite ...

I think you are going to be OK with that. It might need some compensations built in later like a taller-than-usual bridge, or the fingerboard wedge that Steve suggested.

Re: Acoustic Bridge Types ...

The physical forces are different to some degree (at least in my imagination). In the string through method the strings are pulling up on the soundboard, while pushing down on the bridge (which could improve their coupling). In the tie-down method the strings are putting a rotational force on the br...
