Hiwin did all of the machining for us. I cut the mounting flange off of one of the old plastic leadscrew nuts and used that to make a mounting adapter plate for the nut on the ball screw. The only other modification I had to make was to cut a slot in the crossbeam of the gantry under the table for clearance to the grease zerk on the ballnut, so that it could spin without hitting it. I'll try to attach the PDF drawings from the ball screw quote.
