This past week, I have had a couple people complain that the circuit board blanks they received were "bad" or "defective".
When I started turning plastics, I also "blew up" a lot of blanks. I did NOT blame the blank, I realized I needed to hone MY SKILLS. Here are a couple of hints:
1) if you "blow up" a blank and then another and they are different colors, or different shapes, they are NOT from the same "run". The chances you could locate TWO blanks that were truly defective from two different "runs" would approach infinitesimally small. (In other words, it "ain't gonna happen")
2) if you "blow up" a blank and then go to turn another that is exactly the same, LOOK AT the second one. Is it cracked??? In order for it to be "defective", there should be some sort of visible defect. What is it???
3) if you destroy a blank while attempting to face it with your pen mill, DON'T use that pen mill on another blank---if it tore apart ONE blank, it will tear apart another!!!
To me, these points are obvious. Apparently, others see it differently. We try to be eminently fair, so we are replacing these blanks at no charge. But I hope this thread can educate everyone a little.
WHEN A PLASTIC BLANK "BLOWS UP", IT IS NEARLY ALWAYS THE FAULT OF THE TURNER---NOT THE BLANK. Inspect the blanks before you start. If they LOOK good, it is VERY UNLIKELY they have a hidden defect.
To "learn to turn", you WILL have some failures. That is the cost of becoming adept at this hobby.
Hope this helps,
Ed
