My thickness sander

The thickness sander is one of the most usefull machine to the luthier. It is a drum sander, relatively powerfull, that allows to sand some thin pieces on the thickness, but on a large width.

The thickness sander allows to set thickness (about 2mm or so) to  some instrument tops, fingferboards, bindings, backs and ribs.

We can find some comercial versions of this machine, but it is relatively simple to build one, that will be much more versatile than the commercial versions.

My thickness sander, in action : 

As soon as I do not need it anymore, it becomes a table :

In addition, in the prolongation of the roll shaft, it is possible to install an extension shaft, supporting a buffing wheel.

See the diaporama for more details on this thickness sander.

The originality of this machine stands in its table lift system, that can be seen in this video :

Comments are welcome.

Superbe réalisation ! Très très joli travail ! Bravo.

Le dimensionnement des engrenages et leur usinage ? La table s'incline c'est bien ça (il n'y a "que" deux pattes) et donc il y a des charnières au bout ?

Merci !

Les engrenages sont réalisés en contreplaqué, selon la méthode de Mathias Wandel, voir son site : http://woodgears.ca/gear/howto.html

Ils sont tracés en particulier  à l'aide de son excellent outil : http://woodgears.ca/gear_cutting/template.html

Oui, c'est bien ça, le réglage de l'épaisseur de calibrage se fait en montant/descendant la table qui d'un côté pivote sur une charnière piano, et de l'autre monte et descend grâce à ce système d'assenceur à vérins.
Ceci permet un réglage très fin de l'épaisseur.

Cordialement,

Christophe
