Bumfuzzles me why you'd want to cut it up into a bunch of hard-to-handle strands. Just wind it around a dowel as someone else suggested. |

You should shell out the $20 or whatever then (or $100 and get a Mitutoyo or other brand name with a bit better "feel"). I use mine all the time- for rough (0.001") width, diameter, inside diameter (rougher) and depth measurements. A micrometer is useful for precision measurements, but less necessary for an EE.

Unfortunately, $20 is quite a lot of money at the moment :/ I don't have any real need for it - I've got a 0-25mm micrometer, and the plastic caliper fills in for the rest. I don't have any tools that can maintain that sort of tollerance anyway, so my need is less. |

I don't really have that much that I need to hold accurate tollerances for anyway. The file is a much underestimated metalworking tool. |

I haven't used Ampex tape since 1969, in Korea. We switched our three 12-track recorders to 3M tape because Ampex sandpapered the heads. This old war horse finally went CD-R and CD-RW about a year ago. CD-RW is wonderful for PC HD backup. Can't bear to let go of my Teac 4010-SL r/r deck though. I bought it in Thailand in '71, used it until '81 or so, and then packed it in its original box. It's been used twice since then. Every once in a while I pull it out to show to some kid as an antique. :-) |
What wire gauge, if one at all, do metricated industrial countries
use? France, Germany, Russia, China, for example. |
I read in sci.electronics.design that Reg Edwards
wrote (in ) about 'wire size question', on Sun, 10 Apr 2005: What wire gauge, if one at all, do metricated industrial countries use? France, Germany, Russia, China, for example. There is an IEC standard, IEC 60317-0-1, which specifies a range of metric diameters for enamelled copper winding wires. -- Regards, John Woodgate, OOO - Own Opinions Only.

I assumed anyone serious would be using a Mitotuyo ? digital LCD vernier caliper anyway. We certainly have one. I'm trying to figure out why they would be called vernier when they have a LCD display. To distingush it from a micrometer caliper at one end of the tool spectrum, and a monkey wrench at the other. ;-) Cheers! Rich |
