D guitar

The Model 2D is a long scale (28.5″ – 725 mm) guitar designed to be tuned one tone below standard.

Fitting a capo to the second fret gives standard pitch at standard tuning and standard tension. Played open without a capo it has a magnificent depth of tone; played with a capo higher up it blossoms as a different guitar, bright and ringing.

History

A few guitarists keep their guitars tuned permanently low, sometimes a semitone below concert pitch, sometimes a full tone.  But tuning low on a standard scale has limitations, so in 2004 I built a long scale guitar to tune a tone down from standard.  In standard tuning the 1st and 6th strings drop from E to D – hence the name ‘D’ guitar.   (It turned out to be another case of re-inventing the wheel; there were already D guitars in existence).

My first D guitar was built on a 12 fret version of  my Model 1 guitar, and the next few built on 12 fret versions of Martin Simpson and New World models.

When Maurice Condie came to see me about having me build him a D guitar, he suggested I base it on my Model 2.  This has a longer body and was designed as a 12 fret, so needed no adaptation – a really good idea I should have thought of earlier.

The 2D has now become my standard D guitar.  It is available with a German spruce, figured Sitka spruce and now also Douglas Fir soundboard and Maysian Blackwood, African Blackwood and Brazilian rosewood back and sides.

Not only does it play a tone lower, but whatever the tuning the D guitar has a wonderful deep resonant sound, a sound you just don’t get from a standard scale guitar.

Darrell Scott in 2019 playing his 2D. He tunes it a tone and a half below standard, making it a C# guitar.

Two new guitars

Figured Sitka soundboards

Two new guitarsFor many years I’ve not used Sitka spruce for soundboards, having had indifferent success with it when first building instruments. However, it turns out there is Sitka and there is Sitka. While visiting Pacific Rim Tonewoods in the Cascade Mountains near Seattle I saw sets of lovely looking Sitka spruce, both straight grained and figured. They looked so good I bought two of each, and I’ve recently built two guitars using the figured sets. These are a Martin Simpson D model (long scale tuned a tone low) and a New World model, both with African Blackwood back and sides, Wengé necks, ebony fingerboards and bridges, and figured Sitka soundboards. Both are a rich colour and extravagantly figured. And they sound wonderful; I’m so pleased to have another combination of woods I’m really happy to offer. I plan to keep the D model for a while, but sell the New World model (see my ‘available now’ page).

Long neck mandolin project part 8

Back from the spray-booth

Last week Patrick’s long neck mandolin came back from the spray booth. David has worked his magic on it and it looks beautiful, with the golden finish Patrick requested.

I’m leaving it to settle until next week before starting stringing it.

Available now page problems

One instrument gone and another available

At the moment I’m unable to update my ‘available now’ page. My computer guru (aka Jason Sobell) is away from his desk this week so it will be a while before this is sorted out.

In the meantime I can announce that Mike Moskal has sold his Model 2 so this is no longer available.

However, there’s now another instrument available. Stewart McIsaac bought a 10 string bouzouki from me in around 1993 (to add to his earlier 8 string). He now wants to sell the 10 string.
He says it is in good condition apart from a couple of very minor dings, and from the photos he sent, this looks to be the case.

Model 2 D guitar

Maurice’s good idea

Some time ago Maurice Condie asked me to make a D guitar and suggested I build it on my Model 2 body – a really good idea. A 14 fret to the body D guitar has to be based on a 12 fret model, and whereas the MS and NW D guitars I’ve built have been 14 fret bodies adapted to take the 12 fret bridge position, my Model 2 was designed as a 12 fret to the body guitar from the start and needed no modifications.

To my eyes, the proportions work out particularly well, the longer neck balancing the relatively long body. Built with African Black-wood back and sides, a German spruce soundboard and a Wengé neck, it should sound excellent. Both Maurice and I are looking forward to being able to play it.

There are double position dots at the second fret, and standard dot positions from there up. So the octave double dots are only at the octave when a capo is on the second fret, giving standard scale and tunings. I fitted them this way after discussion with Maurice, previous D guitars have had the orthodox dot positions.

Not great photos (especially the one below), but they show the shape and proportions of the guitar. It’s now ready for David and the spray-booth.

Long neck mandolin project part 7

Ready for the spray-booth

Very nearly three months after starting work on it, Patrick’s long neck mandolin is ready for Dave and the spray-booth. I will get it back after around a month, when I will make and fit the bridge and can then string the mandolin for the first time.

Shaping the neck

At this point it was time to shape the neck and add the last piece of binding and trim across the heel.
Here the mandolin is strapped to the neck shaping arm, held in place by a strap round the body and a clamp over the head.


Working to the guide lines drawn on the neck, I start by tapering the sides of the neck with a draw-knife. This Cuban mahogany is a pleasure to work, with the wood peeling away from the knife smoothly. Other woods can have interlinked grain so that whichever way you work, the knife digs in and the wood wants to splinter. Wengé in particular is not nice to work with knives and chisels so has to be rasped and sanded.
The neck has now been rasped into five flats, ready to be smoothed into the final shape.
It’s hard to see in this photograph, but it has also been tapered so as to be a little shallower at the head end.


Here the neck has been rounded with a fine rasp and sanded through the grades. I’ve also fitted the binding and trim over the heel.

Next the fingerboard will be leveled and cambered, dots inlaid as required, and then the fingerboard can be fretted.

Completing the body

With the back and sides fully prepared, I now had to fit the soundboard. This was rough carved, then final thicknessed, sanded and braced so as to be ready to be glued onto the sides. But before gluing, it sat on the warm shelf for at least a week so as to settle into its final shape.

As before, I wanted any movement to take place before fitting so as to avoid internal tension as far as possible.

Before fitting the top, I first checked the fit of the top with the sides (which already had the top lining glued in place). Anywhere the fit wasn’t perfect was trimmed until it was.

This tends to involve going round and round, improving one area while making others just a little worse. But eventually the fit is perfect.

Then I spread the glue around the lining and top of the sides and clamp the soundboard in place.

To take the bindings and purflings, I routed L shaped ledges around the top and bottom of the body using a laminate trimmer and different bearings to give the different width cuts needed. I didn’t photograph this procedure, but here is a picture of a guitar ready for routing.

It is clamped in a flat bottomed cradle to keep it level, and moved around the stationary cutter. The cutter can move up and down to accommodate variations in height, but the width of the cut is fixed and determined by whichever bearing is attached to the cutter.

This has to be repeated with a different size bearing for each different width ledge, i.e. once for the binding ledge and again for the purfling ledge.

I next bent the Cuban mahogany binding, the red/green/gold back purfling and the Birdsfoot soundboard trim to shape on the hot pipe bender, and trimmed the ends to mitre in with the purfling down the centre of the back and where the sides meet.

I ran glue around the routed ledges, fitted the purfling and bindings in place, and then taped them tightly. After all these years taping binding still seems a primitive system, but it works well and my attempts to devise an effective alternative have not worked out.

Part of the problem is the stiffness of wooden binding, as it requires a stronger pull to make sure it is properly in place than does more flexible plastic binding.[/one_half_last]
[one_half]When the glue had thoroughly dried I (carefully) removed the tape before scraping down any proud binding and purfling. I then sealed this and sanded it clean.

Now the body is ready to receive the rosette, and then the neck and fingerboard.

Visit from Eamon Doorley and Julie Fowlis

Today Eamon Doorley and his wife Julie Fowlis visited. Eamon is both accompanist to Julie and long time Danu band member. He was looking at guitar-bouzoukis and tried both flat-top and arch-top versions. Eventually both he and Julie settled on the flat-top model. Here they are in my workshop, Eamon playing it through the Highlander pickup I’d just fitted, and Julie singing.

And here are Eamon, guitar-bouzouki and guitar-bouzouki builder

Long neck mandolin project part 3

Assembling the back and sides

With the finished back settling on the shelf, I was able to get on with bending the sides. When bending guitar sides, I use a Fox bending jig to start with and then move on to hand bending, but for the simpler mandolin sides I bend entirely by hand, on an electrically heated bending iron.

Sides are always bent exactly to shape, rather than bent approximately and forced to the shape of the mould when gluing to back and soundboard. This is to avoid internal stress, as mentioned in part 2

Here the sides are glued and clamped to the tail-block. I’ve left a space between the sides where the tail purfling will fit.


I don’t seem to have taken a photo of the heel-block clamped and glued to the sides, but here are the sides glued to both blocks with the bottom lining glued in place. The lining provides gluing area for gluing the back on; it has cut-outs ready to receive the ends of the back braces.

The sides have been scribed and cut down to receive the back so no pressure is required to pull the back onto the sides. Again, this is to avoid internal stress.

The serial number can be seen stamped into the heel-block.

Again, no photo of the back being glued to the sides, but here’s the finished result. I’ve also added the top lining, which gives the gluing area for gluing on the soundboard, and side re-inforcements.

I don’t see these as providing much in the way of strength, but they should limit the extent of cracks in the unfortunate event of an accident.

The back and sides are now ready to receive the sound board.
