Making A collet Chuck For The Lathe

Video Description

G'day everyone, In this video I will be making a new ER 32 collet chuck for the lathe. I previously bought a MT3 ER32 collet chuck for the mill, which I occasionally used in the lathe as a collet chuck. Whilst it did work, I was never happy with the rigidity of the style of chuck, and the limited length of stock that I could use with it was an issue. In this video I will machine a new collet chuck from a solid piece of 80mm steel. This one will mount to the spindle nose directly, which should be much more rigid. I will also be testing out my new tool post mounted grinder to grind the 8 degree collet taper. I hope you enjoy the video. #machining #diy #minilathe Timestamps 0:00 - Introduction 1:40 - Mounting and Facing The stock 2:44 - Machining The Recess For The Spindle Nose 3:55 - Drilling and Tapping The Mounting Stud Holes 6:26 - Machining The Collet Chuck Body 8:14 - Drilling Holes For The Tommy Bars 8:57 - Cutting M40 x 1.5 Thread For The Collet Nut 9:50 - Boring Through The Collet Chuck 11:10 - Cutting The 8 Degree Taper 13:10 - Grinding On The Lathe 14:10 Sanding The Collet Chuck 14:54 - Final Grind And Test
