| Our
first annual Master Class was held at John Timblins home in
Arlington. We were honored to have Ervin
Somogyi as our guest. Ervin has been making acoustic guitars for
over thirty years and is widely acknowledged as a modern master builder.
The topic of the class was a step-by-step look at how to evaluate
and select tone wood for use as guitar tops. |

The
course started at 9:30 Saturday morning and went well past the dinner
hour. On Sunday we once again started early and concluded in mid afternoon.
We had 19 members attend. At the end of each day's sessions the members
were able to sort through a selection of Sitka Spruce tops that Chris
Jenkins had LMI send us. LMI sent us nothing but primo sets, no doubt
because they knew that Ervin was our presenter and didnt want
him seeing any junk tops. Over seventy tops were purchased by our
members at the very reasonable price of $19 each.
Ervin started the day by discussing the nature of wood. His syllabus
broke down the tone wood selection process into a series of simple
question and answer steps. Each exercise involved examining sets of
wood that he had brought for the process. In fairness to Ervin I cannot
reproduce his questions here, but just as an example here is one of
the early questions.
Examine
plates #5,6 visually.
You may pick them up, but don't flex them, tap them, etc.
What three qualities or properties can you identify by just holding
the wood and looking at it?
Are there more than three? More than ten? More than twenty?
List as many as you can.
I personally came up with five characteristics.
This is Ervins answer to the question: |
| What
kind of wood?, |
quarter
sawn?, |
length
and width?, |
grain
fine or coarse?, |
| thickness?, |
knots?, |
dark
grain lines?, |
run
out?, |
| even
grain distribution?, |
oxidation
patterns?, |
wood
coloration?, |
medullary
rays?, |
| grain
density or tightness?. |
|
|
|
| Absence
or presence of: |
light
reflectance or chatoyance?, |
cracks
or fractures? |
| Texture: |
fibrousness
or smoothness?, |
even
thickness? |
| Stability:Absent
or present, |
weight?,
cupping?, |
warping
or bowing?, |
grain
straightness?, |
| wood
density/hardness?, |
generaly
pleasing?, |
highly figured?, |
rectangular?, |
| good
book match?, |
grain
clarity?, |
contrast. |
|
| Wow!
Thats over twenty characteristics that Ervin looks for
in a top. |
|
After
going though a series of exercises that involved touching, flexing,
and tapping we went outside where there was better light to answer
specific questions about several sets of wood. This is an example
of the probing nature of these questions:
Examine plates #425, 421, 422 carefully, as though you needed to select
one to build a guitar for a jazz player.
Which one might you choose? Why?
Which one would you reject? Why? |
 |
| When
asked to handle the teaching top sets, Ervin asked us to be gentle
and not break the top. I am sorry to report that LINT
now holds the record for the number of broken tops in a single day.

 |
| By
the end of the first day many off us had gained new skills that made
tonewood selection less of a mystery. Many stayed late into the evening
to test their new knowledge on the Sitka tops from LMI. |
| Day
two was devoted to Q&A on the prior day's material. Ervin
presented a demonstration that showed that, contrary to popular
wisdom, that only the lightest [least dense] blocks of spruce
yield braces that are stiffer when quartersawn. If the wood
is normal to heavy in density, this factor disappears and it
makes no difference which way the grain runs. |
 |
| There
was a lively discussion concerning braces and top tuning. Member
Mike Roach brought a top tuning jig that had been built in a
Somogyi course. Shown here on the right. |
 |
|
| We
concluded the event with some LINT business. Don Chesser was elected
president for 2002 by acclamation. Ervin was presented with an Ebony
Monte Blanc style pen that was made by member Sandy Cheatum. |
 |
| Members
John Fitzgerald and Steve Mayo each showed recently completed guitars.
Steves instrument is a walnut/cedar dreadnaught with Martin
style scalloped bracing. Soundhole and fingerboard inlays are abalone.
It is his first guitar "from scratch", actually the third
one I've built. The finish is satin Tru-Oil. Its it the first
guitar he made a commission on! |

John
Fitzgerald's instrument is a classical acoustic/electric with
cutaway and 14 frets to the body. The top is sitka spruce; back
and sides are Indian rosewood; the binding, headpiece veneer,
and rosette inlay are padouk. It was built for Dale
Clark , lead guitar player for Max
Stalling.
All in all the "Masters Class" was a terrific learning
experience. We plan to make this into an annual event. Click
