Restauration d'un tour LION

Premiere vidéo : un truc à ne pas faire : enfoncer une goupille avec le bout des mors d'un mandrin porte-forêt.

J'ai eu la même idée il y a quelques années. Et j'ai bousillé un mandrin...

J'aurais bien pu flinguer une roue ou une noix en bronze du fourreau...

Et juste avant dans la vidéo à 29' : tirer des copeaux longs avec une paire de pinces. Le jour où on se fait un gros copeau de doigt on comprend que c'est une idée stupide. Le doigt peut être sectionné.
