We usually just use a standard variable # on our lathes. We put it at the beginning of the program and on each set up they just put in the number. So for this I would put this at the top of the program:

#500=20.0 (Tail stock position)

In the program then it would be

G152 W#500

Then it is always easy to find the location of the variable to change it. But also we actually assign tool numbers to all of our centers and put that on our tool sheet so that the same center is always used.

Thanks jreynolds5, this will be a big help. Adding Tool numbers to centers is a great idea and we do utilize setup pictures.

Thank so much for your help..
