Making A collet Chuck For The Lathe

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.
