Depends entirely on what tolerance you are marking/cutting/bending to. I
want my students to be able to cut/bend to ten thousandths accurately and
the only way to do that is to scribe.

If you can bend aluminum to a 1/10,000" tolerance you are the MAN. You
must have some really talented students.


That's not the English of it. Ten thousandths is far different from one ten
thousandth. Ten of the little thousandths rather than one of the tenth part
of a thousandth. 0.010 as opposed to 0.0001. Two orders of magnitude
difference. Get it?

yeah, I got it the first time. Just having a
little fun with you. Was it good for you too?

That's why some people call it ten mils, or .010",
or... sometimes ten one thousands of an inch, etc.
