Re: Measuring and marking frets

Not quite what you asked but when marking out clamp your ruler to the board so you only zero it once, and use a magnifying glass of some sort (I have an illuminated magnifier) to help read the ruler. And don't get too worked up about it. The small errors here are probably not going to matter too much.

Disharmony in SS Guitars

This may seem a slightly odd place to put this query but bear with me. I am quite at ease with musicians playing classical style music on steel string guitars but I came across a really disturbing video tonight. I have huge respect for Michael Chapdelaine as a player but I listened to him playing Co...

Re: 8 String bocote falcate braced nylon string crossover guitar

John that does look great. Your description of the ret top is also very timely. I have a falcate braced classical I completed a while ago that is seriously dull sounding. At some point I intend to re top with far less bracing - in fact the opposite of your job and I shall certainly try your technique.

Maple or Sycamore for purfling

I am using (a quite dark brown) walnut for the first time for the body of a classical and want to use a simple white purfling that segments the back into two halves and continues under the binding which will be the same walnut as the back/sides. I had hoped to use some holly that I have in the rafte...

Re: Question re strength of different mahoganys

There are certainly big differences in density between pieces of what is described as mahogany. If it follows the general rule that stiffness correlates with density then you may well have an issue with your repair. I have worked some reclaimed mahogany from old furniture and it bears little relatio...

Re: Multiscale bridges

Mark I agree that the Lowden looks huge. As a builder I would also be concerned about the large mass. I think the point about the cutaway is also important since we have already broken the symmetry and that can be used to suggest a bridge shape. Martin's point about the headstock is also right in th...

Multiscale bridges

I was watching a couple of players on multiscale guitars recently (one of whom was Tony Mcmanus - great player if you don't know him) and the builders had just tilted a standard bridge round. I thought this really didn't look very good. And of course once you've seen it you can't help looking at it....

Re: Louro Faia for binding .. a complete failure

And of course it isn't just the bindings it's the side as well. But we persist because we like the shape and because we love the cutaway, even - actually - especially on classicals. I haven't been quite as sharp on this one but I do like it.

Re: Lutz/Blackheart Sass Hybrid Nylon, venetian cutawy & arm bevel

Trent great detailing. I imagine that scooping of the heel is to further improve access to the upper frets...?

I'm looking with envy at that armrest. I left my last classical with too sharp a corner and end up with a great crease in my forearm!

Re: How big a drumsander?

I have the Jet as with Martin.I seem to have been luckier than him (and some other builders) because it has worked well with no real problems in several years. The width is a bit limited, it will only just cope with Trevor's steel string design. Haven't tried doing a pass with part of the timber sti...

Pore fill Bindings

Do people pore fill bindings?

The bindings are the usual around 6 mm deep by 2 mm width and...

Thanks for that Trevor. It is maybe time to step up from the simple version you described in the book.

I didn't explain too well... this is the neck without fingerboard. I have a minimum of around 6 mm to the truss rod groove so that should be OK.

I have inadvertently taken my neck down to 15.4 mm around the 1st fret. It will get a bit thinner at the zero fret position. This a Steel string done in Mahagany. Is this too thin?
