Spindle Encoder Mount and Coupling

prusaprinters

<p>A bracket and coupling to mount an Omron rotary encoder on the spindle of my SIEG SC4 lathe, for use with the Clough42 ELS system.</p> <p>The coupler is 16mm to 6mm, with a 4mm keyway for the larger shaft, and a hole for a 3mm set screw to secure the smaller shaft.</p> <p>Bracket uses a 1/2" stud that replaces the lower right cap head screw (see pics). This is a fabricated part and you'll need to make one. Length is to suit.</p> <p>I'm putting these on thingiverse in the hope it may help other SC4 owners, but usual caveats apply - these fit my lathe, with the dimensions of my spindle shaft and the distance of the spindle &amp; stud location centres. It's also specific to the Omron encoder that I'm using (E6B2-CWZ6C 1024P/R)</p> <p>I've uploaded the STEP files, in case anyone wants to tinker</p> <h3>Print instructions</h3><h3>Category: Machine Tools Summary</h3> <p>A bracket and coupling to mount an Omron rotary encoder on the spindle of my SIEG SC4 lathe, for use with the Clough42 ELS system.</p> <p>The coupler is 16mm to 6mm, with a 4mm keyway for the larger shaft, and a hole for a 3mm set screw to secure the smaller shaft.</p> <p>Bracket uses a 1/2" stud that replaces the lower right cap head screw (see pics).
