Lathe chuck advice

[rleete]

New 4" 3-jaw is actually more accurate than the 5C collet chuck. Measured about 6" from the face of the collet, the 5C chuck is within .002 runout. Closer to .0015". Not great, but acceptable. I can get the end to run true, but then it is out at the collet just a smidge (technical term). Might be the cheap Shars collets, but whatever. Nothing I do requires any super precision.

I was pleasantly surprised to find the 3-jaw is within .001"!
