Well you don't really make 8 different wizards. You setup the wizard and just change 1 value for each loop. When you exit the wizard will compile all the loops into 1 file.
An option would be to program a parametric macro that would allow you to program the variables before it ran. You could set thread pitch,cutter diameter, finish diameter, cut depth per pass and depth and mach would run the loop untill the final diameter was met and end the sub.
Just a thought, (;-) TP
