Whilst I don't know what your finished part looks like, I would try and write my own wizard.
If you use Vis Basic, you can quickly write a program to thin down your stock to a working diameter, put on rounded ends etc etc,
My manual page, on Mach 3 Turn, has now several other DRO,s available into which I can enter parameters such as starting diameter, finish diameter, length, etc etc. I have written several macros which take information from this page, and then turn the stock down to these parameters.
Roughing down to a diameter is easy, since you can use such commands as "While Dia > Finish Dia" etc "Take another 20thou off".
If you send me some idea of what you are doing, I'll try and put a little macro together for you.
