My Smart Brown 1024 has a 5C spindle and drawbar. Measuring the runout with new Lyndex collets which should be decent and a gage pin of .25" I get .001-.002 runout depending on whether i measure within 1/2" or 1". That seems like too much but I have no reference for what it should be. While it is nice to have the 5C spindle, the area near the headstock has the least wear so although when using a chuck I can maintain less than .001 variation over a respectable distance ( .0005 over 6" ) and less if using a live center, there is .001 variation when using the collet of .001+ over the 2" nearest the spindle.
The 1024 has a D1-4 camlock which has three screws between the cams but they don't seem to affect the runout so I don't see anyway to adjust the accuracy. Any suggestions or advice is welcomed. Thanks, Dave
