So has anyone managed to diy a collet seat regrind? Or know someone in the EU who can do it for me?
So after measuring my new spindle (old one had more problems) I find that the runout is still in the 15μm range (0.0006") and I find that not awesome.
I’ve looked for someone who sells the “Straight Shank Chuck Holder” that is used in the spindle, with a specified runout but it all seems to be chinese “our-calipers-only-have-one-decimal” ebay quality.
And I don’t think its the 608 bearings since they are Japanese quality
