KY ,you are right.Their are still questions that have to be answered.I have one that comes to mind.When you have your pattern stock finished and are ready for the duplicator.What tolerances should you ask for.The pattern will be an exact fit.Should the outside be only .05 " over and all in-letting be exact or should you get it a little under.I have never done this before and are trying to learn,and before i go.Thanks for any help anyone will give one will give.
