Will this fit my non-Buffet clarinet?
While we only guarantee our kits will fit Buffet clarinets without modification, they can be easily adapted to other brands of clarinet by a qualified technician. If you are interested in doing so, please have your technician reference the notes below to see if the key can be installed with no modifications.
You will need to take the following measurements to see if the key and arm can bolt onto a non-Buffet clarinet with no modification. If the clarinet you would like to adapt the key to is out of spec, follow the instructions below:
Left-hand F#/C# hinge tube outside diameter: .115" - .133"
Hinge tube too large - Sand or turn the hinge tube exterior on a lathe (do not ream the hole in the e-flat key)
Hinge tube too small - Usually not an issue, but consider machining an adapter sleeve
Distance between the LH F#/C# hinge rod centerline and the E-flat pad cup centerline: 2.05" - 2.09"
Distance too long - Remove the nylon pin. Using a piece of drill rod, ABS, or nylon, make a longer pin that extends farther from the key. If using drill rod, wrap in heat-shrink tubing to silence
Distance too short - Remove the nylon pin. Key can be ground shorter and pin re-installed.
Length of the LH F#/C# hinge tube (between the key face and the post): .242" - .270"
Hinge tube too short? The rectangular boss can be filed down until the key fits
Hinge tube too long? While this will work, the key will be noisy. Consider machining a small washer to be used between the E-flat key and the existing F#/C# key.
