- 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.
Tone hole alignment
This is done if the tone holes are damaged or less tightness is suspected. The straightening is performed with the utmost care to have as little impact on intonation as possible. More extensive damage to the tone holes is solved by milling or replacing them with a new turned hole and subsequent painting.
Checking the posts
The posts are checked for tightness. Each post must fit perfectly and not move.
Each spindle is cleaned together with the mechanical part in an ultrasonic bath, leveled and polished to a smooth finish. It is replaced if necessary.
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 aligned in a level, then placed in a position to absolutely cover the tone hole. I apply the light test and pressure test (Magnehelic gage). With regular cleaning of the instrument the pads can reliably seal for 5 or more years.
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 quiet and functional 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.
