- The first revision within 12 months after the overhaul is free of charge.
- The warranty of the work performed is 6 months.
- The warranty does not cover external damage to the instrument- (fall, elements, etc.).
- The instrument can only be picked up in person after a play test.
Disassembly and cleaning
Complete disassembly of the instrument, removal of old pads and stop materials.
Dry cleaning of the silver surface
The body and mechanics are rinsed in a chemical bath to remove silver oxides.
The body of the instrument and the mechanics are manually polished with a special anti-oxidant cloth.
Tone hole alignment
This is done if the tone holes are damaged or less air tightness is suspected. The straightening is performed with the utmost care to have as little impact on intonation as possible.
One by one, the pointed screws are removed and cleaned together with the columns of settled lubricants and put back in their original place. It is also necessary to precisely lower and remove the axial and radial clearance of the flaps between the posts. This may require replacing or tailoring the bolt, drilling the thread in the posts, or replacing the insert.
Adjustment of flaps
The bowls are levelled and centred to the appropriate tonal holes, which is essential for the functional sealing of the pad for a long time.
Stretching and checking the springs
The springs are optimally stretched for smooth operation of the mechanism. Damaged, oxidized and otherwise deformed springs are replaced.
Replacement of all cushions
Replacement of all cushions according to the customer's choice. The pads are placed in bowls and flattened, then placed in the appropriate position with paper rings to absolutely cover the tone hole. They are tested with paper and pressure test (Magnehelic gage). As suitable pillows I recommend Pissoni DFL 140J or DFL 40HT pillows .
Replacement of all felt, corks, etc.…
I replace all stop and sealing materials on the whole instrument. I then use a combination of different materials for the quiet operation of the mechanics.
Each instrument undergoes the first test with us to be prepared as best as possible for the customer. When taking over the instrument, we try to fine-tune the intonation, sound and mechanical details so that the player is as satisfied as possible.
