If I were to do it the way you showed it in the video, I'm sure I'd be off more than 2-thou.
At any rate, I think it's a good idea even with accuracy results being as they are. I'm sure tweaks could be made to compensate for this. There are many things that can affect accuracy. You could manually index your part perfectly and any number of things can happen during the normal process of machining that can give us the same 2-thou or more accuracy loss. It's just that some of us rarely ever re-check the finished part after its done to see if we were holding the same accuracy that we had indexed to. Unless there's a visibly obvious loss of accuracy, I just assume that it's all good.
Keep up the good work; and if you decide you'll ever sell these on your own for not to much money, let me know.
