Andy;
This should be obvious to you. For most of the square sockets take out the parts and set them up with a stubby carbide boring bar and load your square boring program and bore them all to a common size. One too big - braze with Si-bronze to build up prior to boring - no shims to come flying out at high speed. The square size on my D1-5 spindle is (IIRC) 10mm and I fear I will break it off sometimes when removing a chuck after extended heavy use. I plan to make a 1/2" socket drive to 10mm square from some 7/8 W1 drill rod so I can use my long breaker bar. (for removing only) As I get older I value having enhanced leverage in a controlled manor such that when a stubborn item does break loose I won't over travel or let a tool go flying. Murphy's law for Auto mechanics - A dropped socket will roll under a vehicle to its exact center unless it fell within the engine compartment, then it will bounce into some nook which can not be observed from any angle. ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
