Do not allow extra space. The system pulls the accordion pneumatic

apart and adding extra whatever is not correct. They move the knife

valve exactly and no more. If you add an extra 1/8-inch for folds

then the total movement changes 1/2-inch.



The accordion pneumatics were covered with pouch leather for the

quickest fastest possible response. They were not covered in cloth

because it slows the response time.



The pouch leather was treated with an egg white solution to extend

their lifespan as well as make them airtight. This enables a Duo-Art

to accent notes. Otherwise this expression is lost when using other

materials.
