I know that using the tailstock offset from center will cause a bar turned on the lathe to have some diametric taper equal to: (offsetx2)/(distance between centers) when it is turned. I also know that this is best done between centers. What I want to know is how much taper can be done like this? What's the sane man's limit to the amount of taper that should be done before looking into using a taper attachment?
Also, I wonder how steep one could get away with making a taper using a 4-jaw chuck, around 1/2" diameter bar, maybe 6" long or so. It will bend with each rotation, so I'm guessing anything more than .010 or .020 over the 6" would be starting to impact straightness and stress the bar?
