You will probably have to retrofit it or have someone make one for you. If yours is a hydraulic grinder the nut is part of a piston that retracts when you move the saddle in rapid.
You can buy Acme Screws and Bras nuts from Green Bay Manufacturing and make something. On the screws I cut off the handle / bearing business end of the original screw and bore a hole in the new screw and press in the old end and pin it . The brass nut is a 1/2 nut that you will have to buy a round brass nut and bore out the threaded portion of the original nut and silver solder in the new nut that you cut in 1/2.

Do-All closed about 5 or 10 years ago. You might get lucky and find an old nut and screw on eBay. There is another possibility - go to SurplusRecords.com and under wanted type need nut and screw for your grinder. Be sure to put in the serial number of the machine. Take some pictures and measure the old ones so you can answer the questions people will ask.

Are you sure that's the right one? Is your machine fully manual or does it have hydraulics? Rich is right on, the nuts are different. The hydraulic machines use oil pressure to split the nut apart to disengage the cross feed handle/screw while the machine is running. If the machine is manual it's a lot simpler job to make the nut. You may not find any NOS stuff just lying around for sale.

Yes it's a manual machine
