Not so smooth operator....
JDstrings 11.06.2013
These are very simple and light weight aluminium adjusters. The shaft is a single piece which is threaded along part of its length. The unthreaded part is fitted into either the body or foot of the bridge and the threaded part fits into the other in a slightly oversize hole to allow movement. The adjuster wheel then moves up and down the thread to provide height adjustment. This is a better design than some other aluminium adjusters I have encountered where the post and wheel are all one piece and the threaded part has to be fitted into a threaded hole (which requires a matching die and more time and effort to fit!)
I have fitted a number of these adjusters on basses with out a problem, however recently I have had problems with a couple of sets where, although fine when fitted, after a few days they have jammed up. On removal I have found the threads to be blocked with metal dust. On both sets I ended up cleaning the threads with a tap and die to regain smooth running. This slightly loosened the wheel on the shaft but seems to have cured the issue and doesn't appear to have had a detrimental effect.
I don't know if I just had a couple of sets that were not cut quite right (although they appeared fine when first fitted) or whether there is something more fundamentally wrong.... If it wasn't for these problems I would give them a 5 star rating, but as it is they get 3.

Cumplen su función.

Recomiendo su instalación por un luthier especializado, pues una desviación de un sólo grado a la hora de realizar los orificios determinará que el puente vaya arqueándose progresivamente hasta quedar inservible. Presenta una construcción robusta, pero hubiera sido deseable que el dentado de la rosca hubiese ofrecido un mejor agarre.

Ajusteurs de hauteur pour chevalet de contrebasse

Il manque une notice d'installation.
Le principe n'est pas clair, la molette ronde agit comme un écrou, on ne sait pas si le trou dans le chevalet doit être fileté ou pas et/ou si la partie non filetée doit être bloquée.

Tut, was es soll

Sicherlich eine günstige Alternative zum Austausch des kompletten Stegs - habt mich noch mal 30 Euro beim Gitarrenbauer meines Vertrauens gekostet, die Schrauben einbauen zu lassen. Einzig - die Schrauben sind etwas schwergängig, aber so oft ändert man die Höhe ja auch nicht.
