I thought I calculate it rather than measure them. I am willing to take McMaster-Carr at their word when the say a wire is say .0055 inches in diameter. If that screen has 42 wires per inch I would assume that the solid area in one running inch of screen would be 42*.0055 or .231 inches. And that the 42 holes, and I am assuming it would be 42 not 41, would take up the remaining .769 inches or would be about 18 thousandths of an inch across. I don't know if it would be better to use width or area as a measure of hole size, any ideas? Anybody see anything wrong with this approach? Once I get all the wire sizes, it would be simple to put the formula into RagTime and calculate them all. Jim Gundlach On Monday, December 16, 2002, at 07:22 AM, rev mark gilstrap wrote: < |
