It took around 30 minutes with the brass spinning at about 150 revs, to make each of the slots I cut in a piece of 1/2" A2 rod, about .8" deep, rotating the workpiece to the next nut flat for an angle reference.
This was nearly the last operation after using G76 with a length of cut taper, to make 50 tpi tapered threads on the shaft, and in a nut. The shaft was bored to accept the end of a small ball screw, as is, threads and all, it was inserted into the end of the A2, and the nut drawn up quite tight so the A2 is compressed onto the screw with a death grip. Its driving the x axis screw in the sheldon 11x36 conversion I am doing. All sealed up with green threadlocker, if it ever fails, I can make another, maybe even with a bigger screw if I can find one whose nut would have a threaded mount on one end. No room for the usual nuts flange in the x axis. The first time I was removing two broken 6x32 taps, and while it worked, I had no way to flush the hole, so each hole had to be blown clean with carb cleaner about 20 times because that K2 was so contaminated it was still a short when the electrode had been withdrawn 100 thou. Can you spell PITA? But I did get the job done and the part salvaged, its the post extension on my toy mill. Thats my story and I'm sticking to it. ;-) > ---------------------------------------------------------------------- >-------- Developer Access Program for Intel Xeon Phi Processors > Access to Intel Xeon Phi processor-based developer platforms. > With one year of Intel Parallel Studio XE. > Training and support from Colfax. > Order your platform today.http://sdm.link/intel > _______________________________________________ > Emc-users mailing list > Emc-users@lists.sourceforge.net > 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.
