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?


A very fine tipped scribe
probably leaves a line in the Dyekem that is .002" wide. You would have
to measure it under a microscope to be sure.

An optical comparator would tell me quite easily.



or maybe you meant .010?? ;-)


That's what I said and what I meant. {;^0
