Of the few long'ish pieces I have tried to machine on my lathe, they have always had some taper to them. I have set the tick marks on my tailstock to "zero" but that has not removed it.
I have never been able to get rid of the taper in my 9x20 lathe. I certainly don't know how it is supposed to be done, but here is a method I tried today and I hope it will work.
I installed a MT2 holder with a brand new dead center into the chuck, and then I used my dial indicator to get it as round as possible. I got it to .001" TIR. I then placed an identical brand new dead center in my tailstock.
Using a high power magnifying glass and a piece of white plastic as a background I brought the two dead center points together at near touching but not quite. Then looking straight down as best I could I moved the tailstock over so that the points were perfectly aligned. As you can see by the tick marks, they are not on Zero anymore.
I hope this will make an improvement. I do not have one of those perfect and true machined bars to place in the chuck and then measure across.
So, do you guys think this was a good way to adjust it?
