Good afternoon Mr Kurt
First: an apology to you, and all other readers – I made a factual error in the original blog, now corrected. It was not the fault of chamfers, but just expecting too much of extrusions.
And indeed, a precision resistor or a crystal are such lovely ways to get a lot of accuracy.
I seem to be floundering in a mechanical world equivalent to filing into the side of carbon composition resistors to trim thinks 🙁
(no wonder mechanical engineers take so long to train… 🙂
