Good one redlite
I know it's frustrating Ross, but you are a craftsman and can fix your mistakes and will always learn from them I'm sure.
I have seen those kinds of jigs for sale all through my career and always resisted buying any of them. I make my own from scraps of hardwood and sometimes drill them out ahead of time on the drill press. I must have drilled tens of thousands of hardware holes in the past 40 years and made my share of mistakes, they can happen even with a jig if not paying attention. I have had to order replacement doors because of mis-measuring door and drawer front sizes plenty of times but never from mis-drilling hardware luckily as many times the hole can be tweaked and covered by the handle etc.
better luck next time
