you need to post a pic of the handwheel end of the tailstock, it looks like my Covmac, if it is, remove the fixings from round the collar and the handwheel and drive screw will come out of the tailstock. It may require a long tube to fit over the screw to tap the collar out, but if you are carefull it should be a simple job. Actually looks like the brass or bronze nut in the quill has failed, tap it out and make a new one on the Hendy! If it isthe quill you are asking about, and need to strip, if the nut is in a blind or flush bore, and cannot be driven out from the other end, if the nut is already damaged, it can be machined out, or bored and tapped for a coarse thread, and have a plug screwed into it, and then driven out from the other end of the quill.
