The drums on this organ were in good condition, so I concentrated on their actions, of the normal Gavioli type. All leather parts were renewed, and all metal parts were cleaned of rust and protected by Hammerite.
This is the bass drum leather as removed from the action. A very common
mistake with these motors is the overlapping of the ribbing. At the
overlap point there are two thicknesses of ribbing and four thicknesses of
leather, resulting in a powerful squashing effect destined for a premature
failure of the motor.
Above and below: working on the drum actions.
The snare drum action before and after. Notice the wood beading round the
motors has been eliminated. With proper leathering - with quirks - it is
unnecessary.
