The bottom of the reservoir has had all of the old leather removed. The new twill hinges have been applied. The organ was once able to be hand pumped but the feeders were discarded some years back.
Both folds of the double-rise reservoir are being assembled. The folds are created by thin pieces of wood called "ribs" held together by twill cloth and sealed with leather strips.
The reservoir top with the twill hinges applied. The long ribs are clamped in place while the glue is drying to keep the pieces aligned.
A small wedge bellows called a "winker" is being releathered. It is mounted on the airline to provide wind stablilty.
Shop woodworker Dave Leavenworth created this sketch of the components to assist in re-assembly of the reservoir.
