Rather than depend on epoxy to retain the inserts, I machine flanges on both ends of the insert that are large enough to allow use of rol pins parallel with the axis of the inserts to retain them, I also make a plug gage the same dimensions as the lead screw to fit the new threads and also to set up the old half nuts on center to bore them out. Brass is a poor material for half nuts, better would be bronze or best, cast iron, which I have used on several half nuts that I have rebuilt.
