Morning Jim
I do a lot of tapers by offsetting the tailstock. But since you are not using the tailstock and the taper gets smaller closer to the stock. My vote is that your headstock is slightly out of alignment with the bed.
Dennis, What do you think???

Hi all,
I'm wondering if someone could give me some advice on getting my
lathe to cut straight. The lathe is a Dalton B6. When I cut a test
bar,(without a center in the tailstock) I get about .005 taper in 6
inches. The smaller diameter is at the headstock end. I would think
that if it was a matter of normal bed wear, the smaller diameter
would be at the tailstock end. I have checked for bed wear by
mounting a travel indicator on the carriage and indicating off the
tailstock flat way. It doesn't indicate any wear that way.
I'm thinking that the spindle bearings aren't aligned with the bed.
As I recall there is about .004 shim under the large spindle bearing
halves to take up for wear in the bearing.
Any suggestions?
thanks, Jim Bonner
