DisclaimerThis is NOT how to make a proper machine tool spindle but is based on surplus parts I had at the time.DC motor drive through chain and sprockets, simple ballrace bearings and thrust ball race at front preloaded simply by adjustment shoulder screw on the rear of the spindle.Spindle shaft is Chinese ER16 collet holderOverall the spindle works very well for 'in chuck' milling of flats, keyways etc particularly when used with an indexing feature.https://www.youtube.com/shorts/-G57_n9BjAU
