ER40 Collet Chuck (1-/12" - 8)

[Surveywaters]

I made this ER40 collet chuck out of 4140ph. The cap/nut was interesting, the withdraw feature looked more complicated than it actually is. There is a non concentric groove that forms a recess offset to the extraction lip. The body and cap/nut are both machined for a hook spanner. The green is an hdpe ring simply for cosmetic purposes.

I may be a newbie, but I know what a collet chuck looks like, and most I've seen aren't anywhere nearly as nice looking as that!

Those are kind words. I 'AM' a newbie, so the compliments are very encouraging.

I get 0.0005" on precision shafting.
