No.7    Manufacturing process  of  diatonic  accordian(全音阶手风琴)

Well,A diatonic accordion is much smaller than a piano accordion.And it's   structually different.    It has ten buttons,each of which produces two notes.One when you push the   bellows in,the other when you pull the bellows out.   The diatonioaccordion,also called the squeeze box  is astaple of Cajun(French descent) music.  

The accordion maker crest the right hand key board from the Maple which is a  hardwood.   Workshop worker saws ten slots,then drills ten holes.The keyboard has no keys has only ten buttons.They produce the triplet notes.

After that, the worker must turns the keybord over  and hollows out the wood   with a router.   This creates space for components to move.Each slot in the keyboard will  housearocker,a piece that links each button to its corresponding airvalve.

then  technician of the Accordion bellows builds the wind chest.the box that  houses the steelreeds.that  produce the accordiance sound.

Moving the bellows in and out,forces air through holes in the wind chest,The   buttons you pushed determine,which reeds get this air, producing notes.   The  longer and thicker the reed,the slower it vibrate,and the lower the pitch of   the note.

a similar way , the shorter and thinner the reed,the faster the vibrate  and  the higher the note.   There are eight reeds per  button,pushing the bellows in activates four,pulling    the bellows out the other four.   Using  a  hot iron,theaccordion maker seals thereed frames with beeswax.  This   prevents air from escaping. 

Now back  to the keyboard.The accordian maker installs ten valves  made of  maple wood.Each one hasa plastic rocker on the end. A spring  ensures the  rocker has just the right  push-buttons to open  and close the vaulve properly   when the musician  presses  the button.

Afterstaining and varnishing the wood, he glues a button  into  each hole onto  the rocker inside.  Pressing abutton triggers the rocker underneat,to lift the  valve  and uncover   the   air   hole,  letting  air hit the designated reeds.   The accordian maker now screws the fuilly  assembled keyboard to  the wind  chest. 

Now the technician constructs the left hand keyboard.  the technician  sets  the reeds into the left wind chest,using a hot  iron  and  bee's waxs(蜂蜡)  just like before  The  valves(风门板) in this keyboard are made  of pine ,a more  flexible wood, making them easier to install in this enclosed space.

On  the  outside,  a  decorative  wood  inlay,a  strip  of ebony  and  some  rose wood detailing. The left hand keyboard has two buttons  corresponding to  three reeds each.It produces two base notes and two cords.

After  staining and varnishing the keyboard, the technician  hooks a spring  between each vaulve and the button that operates it.  the technician  adjusts  the spring tention and checks the air tightness of accordion.

Then he stamps the company name inside.Now the technician  screws the finished  keyboard to the finished windchest.Meanwhile, another technician , prepares  the bellows  which forces air through the reeds. 

our factory buys prefolded cardboard, then cuts and assembles it.These  diamond-shaped pieces of leather, seal the openings, preventing air from  escaping. 

Now the technician  glues fabric strips inside the folds of the  cardboard .This is purely for decoration. These stainless steel covers  reinforce the carboard that they won't perforate from repeated  movement.

Now the technician  glues fabric strips unto the edges of  the folders.This  both decorates and strenghthens the cardboard.  Now for the final assembly. The accordian maker nails the bellows to the left  hand keyboard.Why nails rather than screws? that's largely because tradition.

The  left hand keyboard has a hand strap.The right hand keyboard, a thumb  strap.  After nailing the right hand keyboard to the rest.

this  880 dollar  diatonicaccordian(全音阶手风琴) is ready for a piece of  music.
