I have a horizontal mill set up for turning and boring so I believe I can replace the threaded section of my screw and straighten it in the process. While the screw shaft measures ~.435, the sleeve bore measures ~.479 on the near end and ~.439 on the other.Īt this point I am trying to decide whether to buy a complete telescoping lead screw right now and be done with it or to repair what I have and come back later for the large dial conversion. The bore in the taper attachment sleeve seems to have been wallowed out by the bent screw. Some of the teeth on both that gear and on the telescoping section of the lead screw are a bit mashed as well. The autofeed gear which drives the screw has a wobble to it, I don't believe it is a bent shaft but the gear itself which is bent. The bushing which screws into the saddle has been broken and brazed. Upon taking it apart I have found that the screw is bent in the narrow section between the threads and the taper section. My intent was to just clean it up and put it back together to get it useful and then replace the screw down the line when I intend to do a large dial conversion. Before taking it apart I knew it had issues as the backlash was 48-58 thousandths and the handle had a tight spot in the rotation. The ways are in great shape and so far the rest of the lathe looks OK except for the crossfeed which has seen some damage and a somewhat bodged repair. I believe it is a 1952 and it has a taper attachment.
