Development Verona guitar

My latest development guitar is now built and ready to be lacquered.

It’s my fourth Verona guitar.  It has African Blackwood three piece back and sides, but unlike the previous three, it has a German spruce rather than figured Sitka spruce soundboard.

A more significant change is modified soundboard bracing, and because I design bracing and bridge to work together, a modified bridge.  In this case the bridge is wider.  While shown in the photo in its final position, the bridge is just resting on the soundboard and will be glued in place after lacquering.

I’ve also made a cosmetic change. The binding isn’t black but is now Santos rosewood, still with red/gold/green purfling. Santos rosewood is a rich red brown, contrasting nicely with the darker African Blackwood. Lacquer will bring out its full beauty.

Both soundboard trim and rosette are my MK black and white birdsfoot.

It will be over a month, maybe longer, before I get it back from the spray-booth and can fit the bridge and string it.  A good job I have become more patient over the years.

 

Back view, showing three piece African Blackwood back. I love the look, and there is no difference in sound as compared with a standard two piece back.

Indeed, I have built guitars with five and six piece backs, Martin Simpson’s Brazilian rosewood MS 2 model was one of these.  I was able to use lovely colourful old Brazilian scantlings, 3″ x 2″, and the guitar sounded wonderful.

There is of course a history of multi piece backs. In past centuries, when transport and shipping was not as easy as today, makers used varied woods and sizes as a matter of course.

More recently,  the Martin Guitar company introduced the three piece back D35 in 1965, so as to be able to use the narrower pieces of Brazilian rosewood they had available. It became a popular model and has stayed in their catalogue to this day.

I’ve heard it said that the three piece back gives a different sound to that of the two piece back D28, but I hardly believe this. If there is a different sound, there will be some other change to account for it.

Verona guitar page

I have now put up a page about my latest Verona model guitar      https://www.sobellguitars.com/verona-guitar

This was devised with Massimo Raccosta who lives in Verona; hence the name. At first the idea seemed unlikely, but it grew on me and the Verona turned out to be a fascinating guitar.  To the point where others can sound louder and more dramatic, but this is the one I pick up first every day.

Panic buying

.

 

Today I went on line to find filter refills for my trusty 3M face mask. I’ve been meaning to do this for a while, but not got around to it.  Today all suppliers were out of stock.

Is this panic buying?  Or have woodworkers and others everywhere suddenly realised their filters need changing?

I find this a really good mask. I get a good fit to the face, and as well as filtering out dust, I can use superglue and acrylic lacquer and not get a hint of fumes through it.

On the subject of panic buying, a large 4X4 was recently seen completely filled with toilet rolls.  Madness.  And selfishly anti-social.

These difficult times

And not just difficult, dangerous for many. Many will be in despair as to how they will manage financially, old and medically vulnerable people are aware that catching this virus could be serious and possibly fatal, and the problems society faces will drastically affect everyone.  It’s a time for pulling together, and doing everything we can to help those around us, in particular those less fortunate than ourselves.

Liz and I are self-isolating, our kind younger neighbour will collect shopping for us.

Because I work alone, I am privileged in that I can continue working. Building guitars has been described, not without some justification, as my occupational therapy.  But I’m not accepting visitors until further notice, for obvious reasons.  However, shipping and courier companies tell me they are continuing to make deliveries, so I will be able to ship instruments out as usual.

In my workshop

Today I fitted back braces to the Verona model I’m building. Left is the back with reinforcement struts cut away to receive braces, right the braces are glued and clamped in the go-bar jig.  The back is placed in a mould which has the same radius as the curve I’ve shaped the braces to.

Incidentally, behind and to the right of the go-bar jig I store some of the different purflings and bindings I use.

Reinforcing back joints

 

 

Today I fitted cross-grain spruce reinforcements over the two back joins of a three piece back.  These are light weight and sanded to a smooth curve before fitting.

Here they are glued and clamped in the go-bar jig.  The spruce comes from soundboard off-cuts and is never long enough to cover the whole join. So each join is reinforce by two strips, one from the heel to the 4th brace, and the other a much shorter strip from the 4th brace to the tail. The join will be cut away to receive the brace, so even were that area visible through the sound hole, there would be no join to see.

Backs and tops sanded

The soundboards, backs and sides are now sanded to their respective thicknesses.

They will be stored on the high shelf in my permanently heated workshop until needed.

Joining backs and soundboards

.

 

This is the very start of building an instrument. The backs come to me usually in two or three pieces, (though I have made up to six piece backs). Two piece backs are straightforward, but for the three piece backs I have to decide on the best proportion of centre to outside strips and this can depend on what I have to work with.

Here I’m joining five African Blackwood backs, only one of which was wide enough for a two piece, the rest all being three piece. It can take a while to decide which is the best arrangement to make the best possible use of the wood in hand, and no two backs end up identical.

But it’s lovely wood to hold and to work with, and makes wonderful sounding guitars. Having two or three piece backs makes no difference to the sound, this is entirely dependent on the quality of the wood.

I’m also joining five figured Sitka soundboards, all of which are two piece; it’s unusual  for soundboards to be more than two piece.


Three piece backs with joint faces dressed, glued and clamped. The decorative strips are red, gold and green with rosewood centre.

.

 

Here I’m dressing the joint edges of a soundboard with a router on a specially built jig. Both halves are in the jig, so both are dressed at the same time, ensuring a close joint.

 

 

The clamps used below are aluminium. Not designed for heavy use, they are capable of more than enough pressure for this job and their light weight is easy on the joined boards when moving them around.

All five soundboards glued and clamped. The glue dries in an hour or so, but I leave them overnight to be sure.

Ready for lacquer

Sorry,no photos of binding or neck fitting and shaping, but  binding photos can be seen on my earlier News Page 10, items dated 29 and 30 July 2010. Neck fitting and shaping photos can be seen on News Page 12, items dated 24 and 25 April and 2 May 2009.

Here the fingerboard is glued and clamped to the unshaped neck. Lots of clamps, not for lots of pressure but to clamp even pressure everywhere.

Now a jump to the instrument ready for lacquer.  You can just see the tape over the soundboard area that will be covered by the bridge; after lacquering, this is removed so the bridge can be glued onto bare wood. You can also just see some of the side dots on the fingerboard, showing this instrument to be left handed.

Now it goes to Dave Wilson.  He will have it for around a month, spraying and rubbing down several coats.  It will come back gleaming.

Still learning

Despite my age, it appears I’m still innovating.  After 20 years fitting necks using my current technique, today I made a mistake I’ve never made before. Fortunately not too serious.

20 Feb2020

Back and sides complete

With the back trimmed, it’s time to fit the side reinforcements.  Here they are glued and clamped.

Finally the back and sides are complete, lightly lacquered, ready for final trimming of the lining and final adjustment to receive the soundboard.

And here is the soundboard glued and clamped.

While the glue is drying is a good opportunity to work on the neck.  Here the head has been cut to shape, had its veneer added and the tuner holes drilled.  The rough heel block is glued and clamped.
