there is no guarantee if bad spots are found after duplicating..
Not quite understanding what you mean here. Do you mean if somebody duplicates your blank and finds a bad spot in it they expect to get paid for their time running the duplicator???? I would.
Time is money and $100 to duplicate a stock is bottom dollar. I wouldn't expect a $100 semi inlet to be easy to inlet. Spend more and expect the smith to spend more time running the machine and the stock should be easier to finish inletting.
