Having worked in manufacturing of the F111 FB when they did that I can imagine that to convert over would have cost BILLIONS.

Now would be a good time to do it since we don't manufacture anything in the USA any more, and when the Chinese collect our debt to them from us they will make it happen anyway. 73, Tom Amateur Radio Operator N5GE ARRL Lifetime Member QCWA Lifetime Member "Only a white man would believe he could cut the top off of a blanket, sew it to the bottom and have a longer blanket." -- Old Indian comment about Daylight Saving Time On Mon, 2 Jan 2012 20:17:39 -0800, "Ron D'Eau Claire" <r...@cobi.biz> wrote: >Part of the problem is that in the USA many suppliers consider 3.5 mm and >1/8" the same.
