The ER32 collet chuck has always been on my want list for a long time. My search online came to a nought as none of those I found matches the Proxxon spindle flange. The spindle flange on the Proxxon has PCD of 83mm for the M6 mounting cap screws and requires recess of 70mm in diameter to mount accurately on its boss. I've 2 options available to me:
- Purchase one online and machine a suitable backplate to fit;
- Make one.
After reading several build logs and gotten lots of encouragement from the good folks of Metalworking Fun & Madmodder, I decided on option 2 - to make a Wongster's Production ER32 Collet Chuck.
I took a short video showing how "well" I centred the stock. The wobble was pretty obvious.
That's all I have for now. hope to get more done in my next session.
