So I finally got a zeromaster, looks like the cats meow. The heimer has a 10mm shaft so I figured I'd get a quality r8 collet (hardinge) which I paid about $50 for.
The instructions with the heimer tell you to check the runout of the ballend which I did. Long story short it looks like my hardinge collet has almost .003 runout. I find this really shocking but I checked the spindle surfaces and at most they are .0001 out. Just thought I'd post here to see if anyone can think of something I am missing. I checked my cheap chinese r8 collets and they have virtually no runout.
Thanks in advance
