Re: [SouthBendLathe] Set Up my 16" - Test Cut

Thank you Rogan!  That was very helpful in making me understand that I had a brain cramp.  I should of know better.  My tailstock center alignment was way off and really skewed my numbers.

I redid it with a 12" long 2 1/2" diameter aluminum bar without a center.  I did it just at the ends (9 inch measurement difference) and got it to measurement error.  I then skimmed the whole 9 inches and did a final cut taking 0.002" off the diameter.  Measured every inch over the 9 inches and every measurement was within measurement error (50 millionths of an inch or half a tenth).  I am shocked that its is that good.
