About Our
Instruments
The highest quality materials and attention to detail go into the making of our instruments. Every instrument is made to order and extreme care is taken to get every detail just right.
Reeds
The reeds in a concertina
are often thought of as the soul of the instrument. Although
many factors contribute to the particular tone and playability of an
instrument, the reeds certainly play an enormous role in both regards.
From a manufacturing standpoint, because of the incredibly tight tolerances and
the various angles that need to be machined into the reed shoes, they also
present the biggest challenge to the concertina maker. In our instruments,
we only use what are known as "Traditional Concertina Reeds" which we
manufacture ourselves. As in the vintage instruments, our reed
shoes are made from brass and the tongues are made from blue tempered spring
steel. The tongues are carefully profiled using sophisticated grinding
machines followed up by intensive hand filing. Our reeds are closely
modeled on the reeds from a 1914 Wheatstone
Linota.

Action
The action consists of
the buttons, lever assembly, springs and the pads. 
Buttons: The buttons are a
combination of two parts: a plastic stem and a metal cap (brass, nickel
silver or stainless steel). Using a plastic stem greatly reduces the
weight of the instrument and is consistent with the practice of the earlier
makers who often used either wood or plastic stems under metal
caps.
Lever assembly: The lever arms are cut from
stainless steel sheets and are attached to the lever post with an
adjustable screw. The two most respected of the vintage concertina makers
(Wheatstone and Jeffries) used crushed rivets to attach the lever arms to the
posts. This system provides a more stable and therefore quieter and
faster mechanism than some of the alternatives but it still has a problem
in that over time as the parts wear a noticeable clicking sound develops
(similar to a typewriter). It is sometimes possible to recrush the rivet a
little to eliminate the clicking but it is very difficult to not go too far
thereby causing the lever to permanently seize. After making several
dozen instruments using riveted actions, we developed our own adjustable action
which allows the owner to tighten the action the required amount in
order to eliminate the clicking. It has the advantage in that if it
is overtightened, the procedure can easily be reversed giving the owner
endless attempts to get it right without causing any permanent
damage.
Pads and Springs: We manufacture
our pads using a sandwich of cardboard, felt and leather and we make our
springs out of stainless steel
wire.
Bellows
The bellows is made
up of over 300 pieces of leather, linen, and cardstock. The leather that
covers the outside of the bellows is a high quality bookbinder's goatskin with
an embossed 'cross hatch' texture similar to that found on vintage Wheatstone
and Lachenal bellows. The bellows are available in solid black or with
decorative papers.
The Finish Coats
The
finishing step is the most time intensive part of the operation
and considerable effort has been put into researching and perfecting
this stage of the process. We have experimented with just about
every kind of finish available (nitrocellulose lacquers, french polishing,
various types of varnish) and have settled on what we feel are the two best
products for our instruments. For solid black instruments, we use a
high quality waterbased lacquer which is similar in appearance
and working properties to nitrocellulose lacquer but which is
much more environmentally friendly and is safer to use. For all other
instruments, we use a proprietary hand rubbed finish which has all the visual
qualities of french polish but is considerably more durable. We
put at least 20 hours into the finishing of each of our instruments and on many
occasions twice this amount of time has been put in to get the finish to where
we are satisfied.
Cases
Basic cases are made in shop. Cases requiring more customization are made by
Greg Jowaisas. Here is the
case he built for instrument #6:
