trefle Generalities

We are making all these accessories in boxwood, ebony, rosewood or pernambuco, from traditional pattern, from antique pattern or made to measure.
The fine tuners, that are optional on the tailpieces, are made of ultra light composite component, to avoid the muting effect that heavier components may cause.

trefle Ivory

The use of ivory nails or rings is traditional on English boxwood patterns. Since elephant ivory is becoming rare, a worldwide moratorium has banned its use. We therefore offer a vegetal product called Tagua nut or Vegetal Ivory, a perfectly legal product. On the tailpieces, it is replaced with bovine bone.

trefle Staining of boxwood accessories

Staining is traditional. Its "caramel" colour is obtained by oxidation of nitric acid. The colour can be as dark as required. For special requirements in colour, an extra making time might be necessary. Note that a set of pegs needs to have its cones trimmed in order to dye them to the right colour; this is strictly the job of a luthier.

trefle Tailpiece mounting

Although this may appear simple to some musicians, we do not encourage them to undertake this operation on their own. Indeed, the sensitive adjusting of the tail gut string in its length is of capital importance for a good tonal quality and again, this must strictly be done by a violinmaker.

Neophytes, watch for two more problems:
- to not be able to put the bridge back exactly where it belongs.
- Should the sound-post be a little too stretched in the instrument, it may fall when the four strings are removed.
