A Guitar Back is Born.

A half hour here, an hour there, and before you know it, a guitar back has materialised. I've been making a concerted effort to make progress on this guitar after work throughout the week, when I would typically be less than productive where guitar building is concerned.

The back halves were joined with Titebond as usual, but I thought I'd attempt to use hot hide glue wherever else I can on this instrument. Apart from its great strength and resistance to creep, I enjoy the fact that it's so easy to clean up once the parts are joined and clamped. After allowing a short time for the squeeze-out to gel, most of it can be easily removed with a chisel-shaped scrap of spruce. A sponge dipped in the hot water from my glue pot, wrung almost dry, removes the remainder of the glue pretty effectively.

Attaching braces to the soundboard would seem to be a realistic goal for the week ahead. We'll see whether Murphy's Law allows me to achieve it!

New Design, New Guitar

While the task of spraying my Walnut/Redwood OM remains on the "to do" list, I've managed to sneak in a little progress on a new guitar, this time combining a Port Orford Cedar soundboard with the sister set of Claro Walnut back and sides.

I fell in love with the venerable Martin OM when I first saw one many years ago, and as much as I still admire its timeless design and elegant curves, I feel ready to leave it behind me and develop a more contemporary body profile I can call my own.

I build guitars with the fingerstyle guitarist in mind and, taking note of player preferences commonly espoused by players in that style, I've nipped in the waist slightly, reduced the width of the upper bout and rounded the shoulders, the end result of which - I hope - is a comfortable and aesthetically pleasing body shape. The price I pay is the additional work involved in constructing molds and bending forms to accommodate this new design, so it's sobering to reflect on the fact that until the first body is assembled, I won't know for sure that the dimensions will appear balanced and attractive. Building molds isn't exactly my idea of fun, so I certainly hope I don't have to repeat the exercise!

Back From Africa

After a memorable trip to Botswana in Africa, I'm gradually getting back into something resembling a routine. With the trip behind me, I'm keener than ever to catch up on my hobbies, including not only the guitars I have ready to spray, but also a new guitar featuring a modified body shape and some fresh ideas where the more decorative elements are concerned.

I'll have more updates soon.

A Broken Promise, and Some New Rosettes

After promising myself I wouldn't begin my next guitar until the two I'm currently waiting to spray were complete, I've relented a little and have spent some time fabricating and inlaying some new rosettes over the past week. With wet weather still the norm, and a trip to Africa looming large, it was becoming increasingly unlikely that I'd get to apply finish to those guitars any time soon, hence the broken promise - an opportunity to spend time in the workshop!

European Spruce, with Zebrano, Ebony and coloured veneer rosette

Port Orford Cedar, with Zebrano rostete

Sitka Spruce, with Zebrano and Ebony rosette

Engelmann Spruce, with East Indian Rosewood rosette

I wouldn't tempt fate by proclaiming that I've in any way mastered this aspect of guitar construction, but I'm pleased to be able to produce rosettes like these to an acceptable standard fairly consistently these days.

From Ugly Duckling to Beautiful Swan

There's still a long way to go with this guitar, but the full effect of the black and red theme is beginning to emerge now that the top bindings are in place. As gradual as the process is, I'm pleased to be leaving the "ugly duckling" stage behind at last.

More soon!

The Black and Red Guitar

I've been working on this East Indian Rosewood/Sitka Spruce OM at more or less the same pace as I have the Claro Walnut/Redwood guitar featured in recent posts, but progress has fallen behind a little in recent weeks as I've focussed my attention on preparing the Walnut/Redwood guitar for finishing.

While I wait patiently for a trio of fine days suitable for spraying, it's a good opportunity to catch up a little where this black and red OM is concerned. The purfling has been in place for a week or two, and with the end wedge now installed, I've begun the process of gluing the ebony bindings in place. It's not a task I particularly look forward to, which hints at the fact that I'm yet to feel I've attained any level of mastery over this particular aspect of guitar construction.

It will certainly be intriguing to assess the two guitars' responsiveness and tonal characteristics individually, but I'll be especially interested to make comparisons between them. Shaping of the soundboard braces on both guitars was completed at around the same time, the end result being what I perceived to be similarly responsive tops once I'd concluded the cycle of brace shaving, tapping and flexing. If popular wisdom proves to be well founded, the wood species used in these guitars will have a significant influence on the sound I'm ultimately able to coax out of them, and they'll show themselves to be very different from one another, tonally speaking. On the other hand, my assessment could lend weight to the theory that the sound of an instrument reflects the builder's individual style and methods as much as it does the materials used in its construction, in which case their tonal differences might be more difficult to detect. Whatever the result, and for the first time ever, I can confidently predict that I'll be able to share sound files and/or videos with you here on this blog. Eventually, that is!

Spray Day Delay

With epoxy pore filling of the back, sides, neck and rosette of this guitar completed, it’s a case now of waiting for a string of fine days and a concurrent break in my regular daily work commitments. Without an enclosed spray booth, I need three consecutive days of good weather to complete my spraying schedule, with a day off work an unfortunate additional requirement.

In readiness for spraying, I've calculated the bridge position and masked the top in the area of the bridge and fretboard extension with a thin, low-tack adhesive film known as frisket film. The edges of the frisket film in the area of the bridge are around 3/16" inside the bridge outline. I've found that by leaving such a margin, it's much easier to level sand and buff the finish in the vicinity of the bridge perimeter. The frisket film is removed only after the body is buffed and I'm preparing to glue the bridge.

After two brushed coats of Ilva TF23 sealer, I'll spray a maximum of five coats of Grafted Coatings’ KTM-SV per day, for a final result of 15 coats of KTM-SV on back, sides and neck, with 10 coats on the soundboard. After level sanding and buffing, I’ll end up with a thin, flexible finish that has minimal impact on the responsiveness of the soundboard while still providing an adequate level of protection.

More soon - good weather permitting!

Cheers
