I have a 1/2" rod and I want to to make a 2" long taper from 10mm down to 1mm .SHould I Machine the 1/2" rod down to the .393" ? . What angle would I need to use for that? I keep putting 10 as an angle for 10 degrees? Though I am only getting about a 1" taper and It asks for where to start and End Z and I put Start at 0 and end at 2" For the X start I put .393" or 10mm and end at .05 or 1mm.. It is not coming out correctly.. Can anyone help me with the correct angle and X and Z values? . I end up only getting a 1" long Taper ?
