Its a far cry from the time in So Cal, in 1959, when the startup I was bench teching for, bought a huge Clausing, wasted weeks while the factory guys scrapped ways until it could bore a straight hole through a 26" long piece of 8" diameter bronze rod so the machinist they hired could make us 2 camera cases, using quartz windows the navy gave us, straight enough and accurately enough to fit a 2.5" diameter tv camera that was destined to withstand the nearly 20,000 psi at the bottom of the Marianes Trench. They were on the Trieste when it went down there the only time the navy really used it for a deep dive. And those cameras had faint traces of my fingerprints on the pcb's in them.
But that was long ago and far away from today. 57 years later our technology, much improved in other fields, hasn't improved that much in the deep sea arena. And anyone who says water is not compressable, should explain the pictures of the Trieste's battery banks those cameras took a couple pix of while down there, a cup + of acid had been put in weather ballons and snapped onto the necks of common Sears Diehard batteries, and a wire cage to contain the balloons from being carried away by the water currents. At a bit over 37,000 feet down, those ballons were stuffed inside the necks of the batteries. And were all still there, expanding back outside the batteries when they picked it back out of the water. Those cameras had only one problem, the rubber diaphram separating the sea water from the oil we filled the pan and tilt units with, was pushed down into the gears, grinding a hole in it, but the P&T itself continued to function. > On Nov 20, 2017 09:51, "andy pugh" <[email protected]> wrote: > > On 20 November 2017 at 01:34, John Dammeyer <[email protected]> > > > > wrote: > > > So in other words, what you want already exists in several > > > different > > > > ways. > > > > > What doesn't exist is this solution at a zero dollar cost. > > > > To an extent, it does. > > > > NGCGUI > > http://linuxcnc.org/docs/2.7/html/gui/ngcgui.html > > > > NativeCAM > > https://www.youtube.com/watch?v=fXCdTw6Q-QE > > > > Even, to an extent, my own lathe Macros. > > https://forum.linuxcnc.org/41-guis/26550-lathe-macros > > > > > > -- > > atp > > "A motorcycle is a bicycle with a pandemonium attachment and is > > designed for the especial use of mechanical geniuses, daredevils and > > lunatics." > > — George Fitch, Atlanta Constitution Newspaper, 1916 > > > > ------------------------------------------------------------ > > ------------------ > > Check out the vibrant tech community on one of the world's most > > engaging tech sites, Slashdot.org! http://sdm.link/slashdot > > _______________________________________________ > > Emc-users mailing list > > [email protected] > > https://lists.sourceforge.net/lists/listinfo/emc-users > > ---------------------------------------------------------------------- >-------- Check out the vibrant tech community on one of the world's > most engaging tech sites, Slashdot.org! http://sdm.link/slashdot > _______________________________________________ > Emc-users mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/emc-users Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
