Hi everyone,
Now that my K&T 2HL is cleaned up, I've been accumulating tooling to use with it. I started measuring the runout of my toolholders, and was disappointed to see about 0.004" at 3" from the spindle face. Worse yet, that 4 thou is consistent across all of my holders, suggesting the problem is in the spindle rather than the tooling.
I blued one of the holders, inserted it and gave it a little wiggle. The blue was intact except for 2 small spots 180 degrees apart at the small end of the taper. I put a finger up into the taper and sure enough, there feels like are small burrs right where the contact points were. Looking with a light, there's a couple of small scratches visible at those spots, and a dark ring all the way around the taper at that level.
What's the best way to debur the proud spots? I have a couple of round India stones, one medium and one fine. Would those be appropriate? Or a small needle file? I'm looking for guidance so i can avoid buggering anything...
Thanks in advance
Lee
