4. Expression Box and regulators

It came to us "restored" once before, however, the inside pouches and valves had not been done and the regulator cloth was too heavy.  When we wet the cloth and blew into the unit it blew bubbles at the blue arrow

Overall, it looked good, however nothing was found to be reliable for any length of time, so a complete restoration was in order.

When pulling off the new cloth from the first restoration, it was found to be crispy with rubber falling out of the cloth in powder form.

After sanding off the old cloth

After removing the regulator pneumatics

The leather on the spill linkages had never been replaced.  Here they are pulled off and the linkages has been cleaned 

The new leather is applied to the linkage bumpers

Accordian linkages had never been cleaned, bushed, or refelted

Here are all the pieces laid out for restoration.  Note red felt bushings have been removed for replacement after cleaning of wood.

Each linkage is bushed with new graphited felt.
