[LUTE] Re: Bare spot on soundboard.

2014-08-03 Thread Louis Aull
   Tony,


   It really depends on the angle your arm enters the soundboard and the
   length of your pinky relative to the index finger. If your arm enters
   the lute top well behind the bridge, the pinky naturally falls on the
   sound board. So it makes a good anchor point for finding the strings as
   well as keeping the lute in position.


   As the baroque necks got longer and peg boxes got heavier, the weight
   of the neck could be eased by raising the neck toward your head.
   Unfortunately that changes the angle your forearm comfortably makes
   with the bridge. Watch some of the hot shots and you will see what
   compromise they have reached between the two. Also watch the pinky lift
   on the big chords that involve both the very top and bottom strings.


   As my lutes got bigger I found my pinky raising more and more often,
   and eventually I stopped putting it down. One learns how to place the
   thumb for each chord without putting down a pinky by the relative
   position to the other fingers. My arm now enters the lute soundboard
   from a position directly above the bridge and I pluck the strings just
   below the rosette. The lute rests between my legs with a 45 degree neck
   angle to my body. I have to warm up a bit for my right hand to
   correctly find the basses, but after that I just recognize the chord
   and the thumb finds the note. A big benefit of this position is I sit
   upright in the chair and both arms find a comfortable position,
   allowing me to play longer, without shoulder or wrist discomfort. With
   the pinky up you can tolerate a taller bridge and closer spaced
   strings.


   My swan neck I play now has an beautiful englemann spruce top with no
   finish, touching it for any reason leaves a mark.

[LUTE-BUILDER] order of operations

2013-03-19 Thread Louis Aull
   Bill,


   There are several ways to do this. The way you mentioned works fine and
   gives a good clamp surface under the bridge. I have found that I like
   to glue the bridge on after the top is partially glued on. To get the
   first string to align with the edge of the fingerboard to the
   tolerances I like (the bridge is already drilled), I glue the
   soundboard to the front block and part of the way around the sides. I
   can then bend the soundboard up like the sole of an old shoe to get the
   clamps under the bridge area. This allows me a final inspection of the
   fingerboard action, the string alignment, and the fit of the important
   load bearing braces around the back half of the soundboard with the
   position of the soundboard set in its final position. Enough of the top
   is glued to basically fix the angle of the neck.

2012-08-17 Thread Louis Aull
   I wonder if they sell the mechanism so you could use something other
   than ebony. Most of my lutes use boxwood. The pegs also taper in size
   down to very small ones on the upper peg box of my swan neck.


   On a related topic, I use a tee handle peg wrench which allows very
   delicate tuning, even on the upper box on a swan neck at arm's length.


   If you fear a peg slipping, something is not right with your
   peg/pegbox. Keep the lute in the case and add a humidity gauge. When
   the case drops below 40% RH put water in the humidifier. This keeps the
   pegs round and the soundboard happy.

[LUTE] Re: Eleonore von Schlieben-Sanditten

2012-07-20 Thread Louis Aull
   Jarislow,


   Certain things do stand out as accurate:


   1)  Lay a ruler down the edge of the fingerboard on both sides,
   these coincide with edges of the bridge. The neck was originally a
   baroque lute with a bent neck. The artist does not bother to correct
   the un-esthetic crossing of the neck angle with the extended bass
   strings. This concept is reinforced by the strap connecting to the body
   of the lute. This could not have been a theorbo or arch lute, the strap
   would then likely be attached to the back of the lower pegbox. The
   weight of the upper pegbox would have been too great to use a shoulder
   strap.

   2)  She could not have played the instrument at that angle because
   she would have to support the weight of the neck with her left hand,
   despite the articulate looking pose.

   3)  Strings placed on the unused nut slots would not lie on the
   fretboard unless moved over toward the center of the bridge on the
   other end. The bridge was intentionally re-drilled for this
   configuration. I would conjecture that this was done because the real
   user found the top string too close to the side of the fretboard, or
   wanted more string spacing on the bridge.

   4)  The entire string set is centered on the rosette. Someone
   altered the bridge holes to get the string set centered, and most
   likely to get more strings on the bridge. We can't see if the bridge
   extends beyond the bass strings, I think it might.

   5)  The artist has unusual dirt drawn on the top. There is the
   expected dirt where the higher frets are played, where they rest their
   head on the upper side of the belly, dirt around the bottom from
   handling it, and a faint line from the occasional pinky touch. The knee
   stain around the bottom looks like sweat that was cleaned off. The
   person who actually played this used the strap over the shoulder and
   rested the lute on the (at times sweaty) knee.

   In my opinion, this was a modified 10 or 11 course lute converted to a
   swan neck

2012-06-03 Thread Louis Aull
   Paul,


   The originals used what they had, linen or paper. The material has to
   absorb the glue and should shrink while drying. That leaves synthetics
   out. The silk I use is for larger model airplanes and I get it from
   [1]http://www.darehobby.com/, the #4 is heavy enough. This silk is
   thinner than paper, but stronger than kevlar. I cut it into 1/2" to
   3/4" strips and use a small cup to soak the silk in glue. Allow the
   silk to expand for a few minutes in the glue before applying it to the
   ribs. Smooth it out with an artist brush. Do the odd joints and let
   dry, then do the even joints. When dry, you will barely be able to see
   the fabric. Trim off the frayed threads. To make a believer out of
   yourself, make a trial joint and use paper, linen, and silk. You will
   split the wood before the silk ever splits.

Bill,



A lute rib tapers at each end, which means the outer fibers that would have
made it down to the fastening point on each end are cut. As a result, there
is no circular binding force to hold them down like the center fibers of the
rib have. As the wood naturally tries to straighten out of its bend, the
scallop occurs since there is nothing to stop the outer fibers from
straightening. To enhance this naturally, don't bend the rib completely to
the form, and use some force to pull the rib onto the form to complete the
curve. The edges will curl up away from the form more. To defeat this, over
bend and heat twice so the rib is over curved, and the scallop will lay flat
when forced onto the form. Cut the rib roughly to shape before bending .
Another trick is to fasten the rib at each end on the form and use a heat
gun on the outer edges of the rib. The heat will cause the bent curve on the
outer portions to relax and the rib will curl up more. All these methods
produce a mild scallop. It helps to bend all the ribs before installing them
so they are consistent and will meet up on the form. For a brutal scallop,
you would need a shaped forming iron to force the complex curve (yuk). The
thinner the rib, the more the scallop. However, get too thin and you risk
plastic deformation of the shell at the neck block, and the neck will come
forward, ruining the action.



I use aircraft silk on the back of rib joints and have never had one crack.
I can actually heat the inside of the shell before putting on the soundboard
to relax out any stress in the shell. This also enhances the scallop.



I have seen lutes (60's and 70's) where the maker made the ribs thick and
scraped the scallop out.

[LUTE-BUILDER] Re: Englemann Spruce

2012-05-16 Thread Louis Aull
   James,


   The high grade Englemann I have used produces a very warm full sound.
   It is also by far the best looking wood. It has to be about 20% thicker
   than Alpine for the same strength. I have not worked with Alpine
   because the few pieces I have purchased (top grade) were of poor
   quality by comparison. I like to use Sitka spruce on ren lutes for it's
   brightness.


   Now some words of caution: the soft part of the wood is very soft and
   will pull out with tape. Chip carving on Englemann is extremely
   difficult due to that softness. It would rather tear than cut. Other
   rosette carving produces a lot of fuzz and is difficult.  I don't
   bother with the chip carving and focus on perfecting the rosette. The
   only tape I have found that will not pull the soft wood out is drafting
   tape, used and removed with great caution. I usually leave a few tenths
   of mm around the edges for the final sanding to get the divots in the
   soft wood flat again. It soaks up dirt, stain, and varnish like a
   sponge so plan on being more cleanly. That same sponge effect makes it
   glue better. Anyone who plays one of my Englemann lutes wears a pinky
   protector or does not touch the top. (Including Hoppy Smith)


   Is it worth it? To me, no doubt. After my first Englemann top, I
   wouldn't play the others. I have since replaced all the other tops.

The violin has an overhanging lip around the top and back. This make removal
of either much easier and allows the repairman to move or replace the end
block to effect the neck angle. When the sides are moved, the violin does
not run out of material to cover that. On a lute or guitar, nothing can be
moved without a new top to fit the resulting new shape. You can adjust the
angle of the neck by pulling out the sides or pushing them in. This would
shorten or lengthen the center braces and width of a new top (as well as
it's length).



Historically, the lute soundboard construction does the worst thing you can
do with wood, glue pieces cross grain. So when a lute moved from damp Venice
to dry heated Helsinki, the rapid uneven expansion/contraction of the cross
grain braces opened up cracks in the soundboards or broke the braces loose.
When a crack was repaired, the exposed top of the lute was frequently sanded
to produce a better looking repair, but thinning the area of the repair. In
time, the quantity and size of these cracks affects the sound and a new top
was needed. Look at some of the museum tops in Lundberg's book and see all
the repairs inside. Non-working lutes were not moved around by working
musicians and probably survived better.



I have seen lutes with thin tops that produced a very bright  sound when
new, but in a few years, sank in front of the bridge loosing tone. Fixing
this requires thicker braces and a thicker top.



Finally, when lutes were built in Europe, virgin stands of high quality
spruce were available. Now they are all farmed out. But there is lots of
very superior wood available in Canada and the Northwest. The last tops I
bought were $ 120 each and were flawless. Very tight grain, even grain
pattern all the way across and a lovely slight hazel pattern in cross light.




My experience with 2 ren lutes and 3 bar lutes, has been two tops each on
the ren lutes (sinking tops, cracks) and one baroque lute that is on it's
third top in 25 years. That one was kind of a laboratory, it went from thin
Sitka, to thicker Sitka, to thicker Englemann, I'm still not happy with it.
The new Bruner swan neck is 3 now and is just right. The others will die the
lonely death of neglect as decorations.

   You have insulted lutes, guitars, builders, glue, wood and varnish.

   In your discussion of lute problems you have demonstrated why each

   added longer, wider necks and more strings. Your original was reworked

[LUTE-BUILDER] Re: Lute Neck has risen

2012-03-23 Thread Louis Aull
Anthony,

That is a lot of movement. If the neck itself has not warped, then the ribs
below the attachment to the neck block have. The dome shape of the ribs will
not distort unless the ribs are very thin (1.2 mm for instance). Look
carefully at the shape of the ribs just behind the neck block. If that area
has sunken in any, that is your problem. If a straight edge reveals that the
neck has warped, that is your problem. Also, if the soundboard is thin, it
can distort in front and behind the bridge. The cheap fix is to shave off
the fingerboard and put a tapered fingerboard on in its place, the problem
will continue until the shell begins to crack or the neck becomes unplayable
again. The correct fix would involve opening it up and rebuilding it. 

Good luck.

[LUTE] Broken swan neck

2011-04-27 Thread Louis Aull
   David,



   The swan neck with two peg boxes suffers from a design flaw that was
   corrected in the tripple peg box models. In a tripple box, a large main
   spar of wood runs in almost a straight line up the left side of the
   first box right through the second box. That provides the strength in
   the joint to the second box. The double peg box often is cut from a
   single piece of wood, and the left side of the lower box does not
   continue into the second box. It is cut with the end grain exposed so
   the fibers of the wood do not keep their strenght past that point. The
   offset between the upper and lower box creates a torque to the left
   (twist in the axis of the neck) on the upper box in addition to the
   forward (to the bridge) pull of the strings. It is that torque that
   pulls the top box off, more than the pull of the strings. It "peals"
   the repair open.



   There a many examples of these boxes on the internet, some of the best
   are on the Barber and Harris web site. If you look at the double
   box swan neck models there, you will see that they have widened the
   joint area to the top box to get the spar on the right side of the
   upper box to be one piece to the left side of the lower box. Some
   unwanted weight is added with the extra large joint area but there will
   be no twist problem warping or breaking the top box joint. There are
   other lutes on the web with small joint areas already twisting and
   bending to the left, leaving a gap between the 8th and 9th courses.



   Solutions:



   1) If the repairman is sharp, explain the nature of the forces involved
   and slice a larger piece of wood between the two boxes that adds more
   strength and mass to the right side of the joint as well as the left
   side where the break is obvious.



   2) Graft a larger piece of wood between the two boxes. If you have seen
   how a violin or cello neck is grafted to a peg box, you will see what
   kind of joint is required. This requires a skilled repairman, and some
   esthetic redesign.



   3) Go to the local woodcarvers and have them make a new complete
   box with the improved wood mass between the two boxes. The old peg box
   can be sawed off close to the joint and then the remnants carved off to
   the original neck wood. A luthier could then match the new box to the
   old lute and refit the pegs. If you do this you should consider
   converting to a tripple peg box.



   4) And now for the best one: glue the box back on and use much lighter
   strings (yuck).

[LUTE] Re: Stability of lute in playing fast.

2011-04-01 Thread Louis Aull
   Hi Joe,



   The continued discussion of finger position brought to mind some of the
   mechanical aspects of the lute as well as well. Robert Lundberg in his
   wonderful book on lute construction insists that the bowls of
   historical lutes were shaped down on the sides from in front of the
   bridge to the rose to allow more clearance for the strings. I know that
   this lowering of the sides could also have been due to repair or
   correction of the neck angle. Raising the neck angle without removing
   the neck causes the sides of the bowl to bow out and lower slightly.
   But in looking at pictures of players hand's and instruments of of all
   kinds, guitars, lutes, banjos, a perfectly made instrument may wind up
   in the hands of anyone. A bridge low enough to allow the pinky to rest
   on the soundboard will find itself torn to shreads by the pick of a
   strum player (see Willie Nelson). Perhaps Robert was actually seeing
   the truth here. Look at the finger rest that Chet Atkins used to get
   the rest point up to his very short pinky, yet keep the clearance for
   pick work.



   As the necks got longer and peg boxes got heavier, the neck angle
   naturally rises to reduce this weight. At 45 degrees, the weight is
   half that of 90 degrees. As the neck comes up, the right wrist rotates
   to a position more in parallel with the strings and the pinky has a
   natural tendancy to come off the sound board. This allows the builder
   to raise the bridge to get more sound and protect the soundboard from
   pick damage. Lutes in the 18th century tend to have higher bridges.
   Once the bridge is raised, it's over for the pinky without a finger
   rest or placing the pinky on the bridge. The smudge would have been
   left on some strings. (could the smudgeless soundboards have had a Chet
   Atkins finger rest?)



   At the end of a three hour set, hows your wrist?

[LUTE] Re: Google Art project - more evidence of fluted ribs

2011-02-10 Thread Louis Aull
   The fluting is a natual effect of the wood having no support through
   it's curvature for the outer (wider) posrtion of the rib. The inner
   portion of the rib is continous for the entire length of the rib. As
   the rib tapers inward at the ends, the support is lost for the outer
   curvature and it tries to bend back to it's original shape. The thinner
   the wood, the more pronounced the fluting. At 1.7 mm thick in maple,
   there is not much fluting. At 1.2 mm thick, the fluting becomes
   pronounced.

   Herbert,



   You are better off soldering one of those very bright LED's (or
   several) to a stiff set of wires. Both the wires and LED fit through
   the rosette and can be positioned right next to the braces near the
   soundboard. I make a template out of sheet aluminum with a hole smaller
   than the selected rosette hole, so the rosette is not touched during
   this procedure. The template is taped to the top. In a dark room, this
   method can spot loose braces and can measure both the thickness and
   height of a brace, by it's shadow. With the LED, you don't run the risk
   of burning the top, or electrocution.



   They are getting those little USB cameras smaller and smaller. Soon

[LUTE] Re: pegs

2010-03-29 Thread Louis Aull
   Herb,



   The string players in the band are constantly moving the pegs while
   frequently tuning. Some of them go down several notes and then come
   back to the note. All that motion keeps the peg dope distributed around
   the peg, and allows for constant readjustment of the peg tension. If
   you have not noticed, each of them also attempts to keep the instrument
   humidified with a humidity source in the case. It is humidity that
   causes the pegs to vary in shape with regard to the pegbox. When the
   pegs get out of shape, they do not present enough surface area to the
   sides of the peg box hole, and require a lot of pressure to secure.
   This is a good way to crack a peg box. When the humidity in the case
   begins to drop below 45%, start feeding your humidifier with daily
   water. This means you need a humidity/temperature gage and a humidifier
   in the case. There are some great little hygrometers for cigar boxes
   that will work fine. A guitar humdifier will work as well. Keep the
   lute in the case when not in use. After the pegs smooth out, take an
   afternoon and put fresh peg dope on all of them. All that pressure will
   force all the old dope off the friction area of the pegs. I have
   forgotten about the anoyance of unspun pegs since maintaining the
   humidity. I have 3 lutes up to pitch right now, all at 47% humidity.
   That's 67 pegs, and no slipage.

Holding an instrument and breathing on it humidifies them a little, placing
that instrument in a relatively airtight case helps hold moisture. I keep a
few older lutes hanging on the wall de-strung for decoration, but my playing
lutes I keep in the case with a humidity gauge and a humidifier when needed.
When the relative humidity in the case falls near or below 45%, I start
putting water in the humidifier, sometimes once a day. I keep the lid closed
after the lute is removed to hold the moisture in. Everything in the case
must remain humidified, especially the lining.

Alan,
 
I nearly stopped playing because of a congenital hearing loss. Amplification
saved the day.
 
Ask any performing acoustic guitar player and they will swear by internal
pickups over external mikes. Easy if you have a hole large enough in your
soundboard. I find two mikes are needed because on a good lute, the sound
source wanders around the top as you change registers. On my baroque lute, a
mike about a foot from the soundboard and even with the lower back corner
picks up most of what I want. This is below the lute in my lap, a foot in
front of it, even with the back edge of the soundboard and aimed just behind
the treble side of the bridge. A second mike anywhere near the rose picks up
the rest. Without two mikes, the trebles start fading in one postion, and
the basses fail to be heard in another.
 
I feed this through a bandpass filter (equalizer) to correct my loss, to a
set of studio grade headphones. Your setup will depend on your instrument
and ear.
 
You hear good even in a crowd, and you can sit upright. For performances, I
hide the earphones using little bose earpods. You can quickly pop these out

[LUTE] Re: s there a non-spruce topwood in your past/present/future lute?

2006-10-14 Thread Louis Aull
I have built lutes with both the cedar and sitka spruce tops. The cedar was
tried in an attempt to get the thing to stay in tune better, with less
expansion due to humidity. This was done on a light instrument with a thin
top. It produced a soft, damped tone and did stay in tune well. Within 5
years, all the spring was gone and the top was tonally dead as well as
warped. This is why aircraft spars are spruce and not cedar. The sitka
spruce tops produced a very strong bright tone, make excellent rosettes, and
crack easier. These seem to me to be better suited for bright ren. lutes.
The last top I put on this summer was softer engelmann spruce, this produced
a rich full tone for the bar. lute. I like the brilliant white apperance, I
don't like the fuzzing while cutting the rosette. This one had a definite
"break in" of about 4 weeks, during which it sounded tight. Now I like it
just fine. 
 
I'm not rich enough in time to keep a set of lutes with different tops for
side-by-side comparison. I make my lutes for myself, and this represents
only my opinion. The swan neck Brunner I've started will have the engelmann
top.

I made a few lute tops with cedar to try to stabilize the tuning, since

That 45 to 40% works for me. The manufacturer of the humidifier pod I

2005-12-23 Thread Louis Aull
Gernot,
 
You understand perfectly, Vance did not understand the orientation given
in the book. He thought parallel ment with the grain in the belly, not
with the surface of the belly. The braces and their grain lines run
across the width of the soundboard, slab cut or not.
 
The slab cut allows long runs of the thin braces to be of consistent
strength and mass throughout the entire brace length. If the grain was
up and down in the brace, it would be stronger, if you got more than one
or two of the grain lines to run the entire length. While thinning them,
if you cut into one of the grain lines, the strength would be reduced
considerably in that area. Because they are so thin, slab cutting
insures that many grain lines are included, and so consistent strength
though not as strong. The brace is made a little wider to compensate for
the lower strength. When a brace can be thick enough, the grain is
always turned vertical as in aircraft spars and violin/cello bass bars.
 
Merry Christmas.

Vance,
 
Lundberg says: "Bars are split from ... with the grain running parallel
to the belly" Photo 36 page 103.
 
He is saying that the grain lines i.e. yearly growth rings in the braces
should run parallel with the belly surface, not the belly grain lines.
This is called slab cutting. The grain lines in the belly will be at a
right angle to these  braces. It is the top that will have the problem.
The wood will swell more in the wide direction than in the long
direction. The braces will swell at basically the long rate since they
are oriented with the grain "longwise" along the width of the belly.
 
If braces were cut with the grain running in the same direction as the
belly they would look like they had vertical zebra stripes all along
their length and the braces would not have any of the required lateral
strength. They would only add mass to the area attached. The bridge
itself is cross glued, and most cracks originate near the bridge. Refer
to Photo 1 Page 34 and Photo 2 on page 36, these clearly show the
orientation of the grain, so does figure 8. ( note cracks and repairs )

2005-12-23 Thread Louis Aull
Vance et. al.
 
The wear factor causing thinning of the instrument has two parts, lutes
and instruments continually played since. Having personally repaired a
Nicolo Amati violin, which was built then and played ever since, the
sides, back and pegbox did not appear to have any of this thinning. But
the top was only about 1/2 original wood. The hyde glue dries out and
the instrument gets re-glued every 75 years or so, the bass bar looses
its elasticity and must be replaced. Concert A rises and the neck gets
longer. All these operations tear away some of the top material, and so
after a while the top is "plated" so that a lot of the wood is put back
in around the edges.
 
The lute has the top braced so that the reinforcing wood runs at a right
angle to the grain of the belly. A recipe for disaster. Any wood worker
will tell you that wood expands farther in one direction than in the
other and cross glueing is to be avoided at any cost. The tradition of
an unfinished belly is said to allow for the frequent repairs. Have a
lute made in cold dry Helsinki and then send it to warm humid Venice and
oops, many cracks. The easiest way to do major repairs inside is by
parting the belly at the bottom, below the bridge. All this work causes
the resulting repairs to be easily visible on the top surface of the
belly. The repairman would naturally sand or scrape the top flush again
so as to get paid for a good repair, thus thinning the belly. My 13c
lute needs a new top after 15 years now. I have repaired a few cracks,
and after the last repair, decided not to remove any material and let
the repair remain visible, or the top would get too thin. As soon as the
strings give out, I'll put the new top on. ( the new top is in fact a
little thicker, with a little stronger bracing )
 
An instrument is a high performance structure. Like a boat or and
airplane. There is just enough material there to do the job. If the
airplane were heavy enough to insure no damage in a crash, it wouldn't
fly. If a boat were heavy enough to never need repair, it would require
too much energy to propell and wouldn't be used. Thinner lute tops are
intially brighter but require frequent repair and replacement when they
warp and turn dull. Thicker tops stay in tune better and don't break as
easily. If you are not a builder or know one, the answer is in the
middle. If the Amati was not in use, it would become a wall decocration,
with the repair cost being to high for restoration. One has to consider
that unplayed instruments that remain today may just be heavy enough or
ornate enough to survive. Working instruments, airplanes, and boats just
get beat to hell.

[LUTE] Re: Flightcases

2005-11-12 Thread Louis Aull
Ben,
 
I had just discussed this with Lynda Sayce after reading her laments on
the same subject. I had built a "one case fits all lutes" fiberglass one
that carries any instrument I own. It has made many flights and I have
watched the baggage handlers drop it out of a commuter jet onto the
tarmak with only minor scratches to the case. It looks more like an off
shape box than a lute case.
 
Roadie cases are plywood with a metal edge protection meant to be
stacked in trucks. Airline boxes need rounded edges and more impact
strength. Here is some of what I wrote to Lynda:
 
By the way, good rules concerning airline transport for large delicate
checked items:
 
1) Too awkward to throw. ( must pick it up with 2 hands )
2) Absolutely no protrusions. ( handles, latches, wheels )
3) Rounded corners.
4) Crush proof. ( must support a person or two or a transport carrier
truck )
5) Interior support must protect to 30g's ( 10 foot drop )
6) Waterproof. (sometimes big luggage sits on flat cars in the rain )
 
Many companies make heavy polypropolene containers that meet these kinds
of specs. The handles, latches, and hinges are recessed, and all corners
are well rounded. We transport items like telescopes, spectrographs, and
delicate scales in these. These cases are heavy.
 
For my own lutes, I made a "one case fits all lutes" from fiberglass. I
can check any lute in it ( no theorbos yet). I used fiberglass to
lighten it. Normal fiberglass cello cases are made from blown or
"chopped" glass that is used to make boats and car bodies, quick and
cheap. Woven fiberglass is more expensive and is used to make gliders,
formula 1 cars and kayaks. A kayak uses a solid layup for high impact
resistance, a glider uses a foam sandwich construction for the highest
strength with the least weight. The foam sandwich was what I used, to
minimize the weight. This case is a little bigger than a normal lute
case, but weighs about the same. You can jump on this one, or run over
it with your car. It floats.
 
You might contact a local glider repairman or kayak builder and interest
him in a project like this. There is no mold involved. We stacked blocks
of styrafoam, shaped the stack to look like the case we wanted using
coarse sandpaper, then did the layup on the outside of the block. After
it hardened, we cut out most of the foam and glassed the inside. Viola,
foam sandwich case. If you can interest anyone, I'd be glad to send
pictures.
 
By the way, good fiberglass work is not for cadets.
