Reedmaking
101
by SFC Chris Eberle
This is part one in
a series of articles on basic reed making techniques for bassoon.
These procedures are, with a few variations, the same as taught to me by
Louis Skinner in 1985. Mr. Skinner called this particular reed model
"Windsor Mill". It is a good basic reed for any skill
level of player from beginner to professional. I have used this reed
since college with no major changes. The dimensions and shape have
remained exactly the same. I play on a Fox Model I (long bore) with
a VCD #1 Heckel bocal. I have also used this equipment since
college.
Here are the tools
you will need:
Items you can obtain at
a hardware or art supply store:
Ruler calibrated in
millimeters
Exacto knife (#11 blade)
Needle nose pliers
Nipper pliers
Sapphire dust file (Revlon
works well)
Pipe cleaners or small
spiral brush
Cotton string
600 and 400 grit wet/dry
sandpaper
Duco cement
Vaseline
Sharp scissors
Items to get from a
double reed supply house:
Reed Knife
Ebony plaque (metal plaques
beat the heck out of your nice sharp knife)
Reamer
Forming mandrel
Holding mandrel
Nylon reed thread
Brass reed wire

Reed nomenclature
The primary goal in
reedmaking is consistency. It is important to
do each procedure identically on every stick of cane. If every reed
is the same in dimension and specification, you will only need slight
variations in finishing techniques to produce a good reed. The
majority of the control in the finished product occurs in the preparation
of the cane sticks before forming the blank. Here are the steps to
prepare a stick of gouged, profiled and shaped cane for soaking.
Remember that precision is very important. Even a ½mm variance can
make a difference later.
- Beginning with cane that is gouged only:
soak for about 24 hours. OR you can profile and shape dry cane
if you have a straight shaper (I use a Fox #2).
- If you use a straight shaper, you can
shape at this point. If you use a folder, you will have to
profile (and soak) first of course. For better accuracy, change
your Exacto knife blade after shaping 2 or 3 sticks of cane. A
sharp blade ensures a clean cut every time.
- Profile the stick(s). Don’t set
the profiler too thin. While it’s nice to try and save time
later by starting with a thin stick of cane, this can make it more
difficult to form the blank accurately and consistently.
Remember that a reed doesn’t need to be a certain thickness to play
well. Rather, it needs to be well balanced and constructed.
- Tie or rubber band the cane to a dowel
and allow to dry for at least 24 hours. The dowel keeps the
sticks from warping and ensures any variations in tube diameter are
eliminated. (obviously you can skip this step if you are working
with dry cane)
- Measure off the locations for the
collar, and the 2nd and 3rd wires. The 3rd
wire should be 7mm from the butt. The 2nd wire should
be 18mm from the butt. The collar should be 30mm from the
butt. Mark in the center of the bark with a sharp tool such as
the exacto knife or a scribe compass.
- On the inside of the stick, mark
off the locations of the collar and the 2nd wire. The
area in between the marks is where you will be working in the next
step.
- Measure the center and sides of the area
with a dial indicator or caliper (calibrated to .01mm).
- Sand or scrape until the cane measures
1.1mm thick on the sides and 1.05mm thick in the center. The
thinner center helps with response and intonation in the high
register. When you are done scraping, sand lightly with 600 grit
to smooth out the entire inside of the stick.
- Bevel the sides of the stick in the tube
area. The idea here is to provide a large sealing surface when
the tube is formed. Bevel with 400 grit sandpaper from the butt
to just past the collar marking. Be sure the bevel transitions
smoothly to the blades. Do not overdo this! If you
bevel too much you may have a gap where the tube ends and blade
begins.
- Using the dowel and the exacto knife,
cut a groove from left to right across the collar marking.
Don’t be afraid to make this a deep cut. Rock the knife from
left to right. Be sure you’ve started with a sharp blade.
- Remove the excess bark from above the
collar marking. Do this with the exacto by cutting parallel to
the blade into the beginning of the bark, stopping at the
groove. Tilt the knife upward to break off the excess bark.
- Use the nail file to smooth the area
you’ve just cut off. You want a smooth line from collar to
center stick. File carefully on the sides so you don’t create
a knick. Look at the stick in the light to be sure there isn’t
too much cane still at the back of the blades. The collar should
now be sharply defined.
- Still on the dowel, use 400 grit
sandpaper to sand the entire blade surface a little. The goal
here is to remove a bit more material and save finishing work
later. Don’t overdo this! If the cane is too
thin, especially at the sides, the tip opening will not form
properly. Finish the blades with a few strokes of 600 grit to
make them smooth.
- Cut 3 score lines from just below the
collar to the butt on each side of the bark with the exacto
knife. Start them 3mm from the edge. Be sure to cut all
the way through at the very end (butt).
- Measure from collar to collar and find
the exact center. Make a mark here. Score gently
with the reed knife by rocking from left to right. Bend the
stick carefully until it starts to fold on the score line, then
stop. Do not fold the cane all the way over!
- You are now ready to soak.
You should soak the cane
for at least 12 hours in water. At first, the stick will
float. Make sure it is completely wet. After a few hours, it
should sink. Here are the steps to form a blank:
- Remove the stick from the water and fold
it in half. Line up the butt ends on your tabletop. If the
collars don’t line up perfectly, that’s OK.
- Wrap cotton string around the tube from
collar to butt. Wrap fairly tightly. Put the cane/string
back in the water.
- Grease your forming mandrel with a
little Vaseline. Cut 3 lengths of wire (about 3½ inches).
- Now for the moment of truth; insert the
mandrel in the butt end of the reed. Slowly work the
mandrel in with small twisting motions in both directions. Hold
the reed by the tube sides but don’t squeeze. Let the
mandrel’s shape do the work. Squeezing may cause the tube to
split. If a split does occur, it’s OK as long as it doesn’t
go too far into the blades. Usually, these splits are only
surface cracks and will be scraped away in the finishing
process. Also, as you insert, be sure the reed remains straight
from bottom to top. Excess twisting of the mandrel will cause
the whole reed to be twisted. The seam between the two halves
should be perfectly straight and the blades should meet at the edges,
not overlap.
- When the mandrel has reached the
predetermined point, unwrap the string to just past the 3rd
wire mark.
- Put on the wire with 4 hand
twists. Using the needle nose pliers, pull the wire and twist
counterclockwise. Don’t overtighten! You don’t
want the wire to cut into the bark. As you make more reeds, you
will develop a feel for this. Wire tension does make a
difference in how the reed vibrates so it is important to be consistent.
- Unwrap more string and put on the 2nd
wire with the knot opposite the 3rd wire.
- Remove the string completely. Cut
4 lateral grooves on the top, bottom, left and right between the wires
with the file.
- Mark the blades 38mm from the 2nd
wire. This will be the point to cut off the tip.
- Place the 1st wire 29mm down
from the tip marking. Make this wire a bit less tight than the
other two.
- You’re done for now. Let the
reed dry out for at least 8 hours or until the wires are good and
loose.
The final steps will
prepare the reed for finishing and playing.
- Tighten the wires from the bottom
up. One twist for the 3rd and 2nd, 1½ for
the 1st.
- Cut the excess wire off. Leave
about 4 twists on the 1st wire and 2 on the 2nd
and 3rd.
- Fold the 1st wire down and
the 3rd wire up. Leave the 2nd wire alone
for now.
- Begin wrapping the colored thread by
trapping it under the 3rd wire knot. Wrap 3 turns
below the wire then 3 turns above. Then, begin the turban by
going top to bottom at a 45º angle. When the 3rd
wire is covered, finish wrapping by going straight across until you
reach the 2nd wire. Tie off the thread and fold the 2nd
wire down to hold it in place.
- Finish off the turban by coating it with
Duco cement. This will need about 3 hours to dry hard.
- When the Duco is completely hard,
remove the reed from the mandrel.
- Cut off the tip at the mark with a pair
of sharp scissors. Be careful to cut straight across so
the tip isn’t crooked. Snip off the corners just a bit to
protect them from harm.
- Ream the tube up to the 2nd
wire. You might want to mark the reamer with tape (18mm) so you
don’t go too far.
At this point, I usually
soak the reed and crow it to see how it turned out. I don’t
recommend playing or working on it at this point. The next day, ream
the reed again, as the tube will have shrunk a bit. It’s best now
to put the reed away for a few weeks if possible. I’ve found that
working on a newly made reed is more difficult than working on one that
has had some time to settle. New reeds will change more as you work
them. The most frustrating thing is to work a reed until it plays
well then have it turn to *&%$#@! the next day. The operative
word here is patience. After a few weeks, work on the reed little by
little. I usually scrape a bit, play a bit then put it away. I
might spend 2 weeks tweaking a reed (a few minutes every other day) before
it’s ready for prime time. The slower you work, the longer the
reed will last and the more consistent it will be.
