Remove the original know from the grinder to do this, the forces needer are quite important, I used a hammer an a piece of wood to protect the original dial knob.</p> The cover (Couvercle.stl) is placed later on top of the knob after you setup you grinder to the "0" position. <p><strong>Step 2</strong></p> <p>The worm gear (vis sans fin.stl) is secured inside the housing to the dial knob (Bouton.stl) with a headless M3x12 mm screw.You will habe to thread the M3 across both parts prior to lock the screw.</p> <p><strong>Step 3</strong></p> <p>2 M4 threads are required on the side of the grinder to attach the housing (Carter.stl). A drill guide (Posage.stl) will help to position the initial 2.5mm holes. The drill guide is placed on the upper corner flushed with the front face of the grinder. I did place 2 M4 helicoil thread inserts right away to make sure I have a good fixation of the housing. 2 M4x10 mm screws are needed. You may also have to file away some of the side guides from grinder cover not to interfere with the M4 screws.</p> </div></p></p></p> Category: Kitchen & Dining
