Taper per inch

I have a part that has a call out for taper on diameter per inch of length, lets say .0005 tol. So from what I gather this is the major subtract the minor divided by the length and this distance can't deviate more then the .0005 tolerance it's given. how would you guys go about dimensioning this. I don't believe I can get the dia. of the large end, I can get the small end though. I can try and provide picture, btw I worked out he math for what the angle needs to be but its extremely tight and would say unattainable. less then a minute of tolerance.
