Gunner "Lenin called them "useful idiots," those people living in liberal democracies who by giving moral and material support to a totalitarian ideology in effect were braiding the rope that would hang them. Why people who enjoyed freedom and prosperity worked passionately to destroy both is a fascinating question, one still with us today. Now the useful idiots can be found in the chorus of appeasement, reflexive anti-Americanism, and sentimental idealism trying to inhibit the necessary responses to another freedom-hating ideology, radical Islam" Bruce C. Thornton, a professor of Classics at American University of Cal State Fresno |

My Compact-5/CNC lathe (Emco Maier) operates from a line cord at 117 VAC (with jumpers inside for lots of other options since it was made in Austria with exporting to many countries in mind. Granted -- this is a small one -- 5" swing.

Let the Record show that "David R.Birch" on or
about Sun, 05 Jul 2009 16:43:06 -0500 did write/type or cause to appear in rec.crafts.metalworking the following: StickThatInYourPipeAndSmokeIt wrote: On Sun, 05 Jul 2009 12:28:50 GMT, (Nico Coesel) wrote: A CNC machine is something different than a light bulb.

I know of zero CNC machines that operate from a line cord. Which demonstrates how little you know. I've worked with several CNC machines intended for secondary operations that could be moved around the shop as needed. All ran off a line cord. I was going to ask "When the cost of getting a permanently wired lathe inspected is $1500, verses inspecting the same lathe with a pigtail and a plug in for $500, which rout do you reckon the shop will take?" Heck, I know of houses being wired up with a big plug where the house power would connect. Made the entire house "an appliance". EE - weird bunch. pyotr - pyotr filipivich We will drink no whiskey before its nine. It's eight fifty eight. Close enough! |
