ER 32 Collet Chuck for SB 9"

[Shawn]

Starting to take shape. I realized tonight that I'm going to be about .3" undersized on the length of the bore for the collet, I'm hoping that won't effect its gripping strength by too much? I thought I had measured everything out quite carefully?





I couldn't measure any discernible runout on the chuck body tonight, the needle had just a slight vibration to it which I'm chalking up to surface finish.

Edit: hey guys how bad do you think having the bottom .3" of the collet hanging out past the tapered bore will be? I was thinking last night that I could always change this to an ER25 collet chuck as I have one of those in the shop as well. That would shorten the collet by a little more than 6mm and would fit the length of the bore perfectly? Thanks in advance for your advice.
