Nope - the lead screw does not turn - nothing does when you engage the drive. I'm referring to the basic feed operation of moving the tool for turning, not cutting threads, which is what the split nuts do. I now have the information I need from the renovating book to tear into it and figure out what's wrong. I suspect some worn shafts have allowed two set of gears to engage at the same time which is not supposed to happen, but inspection will reveal all!
There are three inverted V ways and one flat way. This is a SBL 10k model.
