That's what the Denford ORAC was based on. Somewhere there's a forum thread with a full teardown of an ORAC. You *can* mill out the existing channel in the saddle for a ball screw, but it has to be a quite small one. That's why I decided to CNC my $50 JET 9x20 rather than try to get an ORAC - especially because I don't care for the way Denford did the cross slide. They cut about the back 1/3 off it and its stroke is limited, no way to mount rear tooling and a gang tooling plate would also be limited. I'm going to mount mine in tension to make it a bit stiffer. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
