matto Posted February 6, 2013 Share Posted February 6, 2013 have everything free and moving. now need to figure out how the treadle will work. basically the length of the support arms that attach the foot pedal to the shaft. Quote Link to comment Share on other sites More sharing options...
ciladog Posted February 6, 2013 Share Posted February 6, 2013 It was a screw cutting lathe but you seem to be missing a whole lot of parts on the headstock end. Quote Link to comment Share on other sites More sharing options...

matto Posted February 6, 2013 Author Share Posted February 6, 2013 ciladog what parts?? know of any pics?? Quote Link to comment Share on other sites More sharing options...
ciladog Posted February 6, 2013 Share Posted February 6, 2013 Matto, That long screw that runs parallel to and below the lathe bed is a lead screw that engages with the carraige to cut threads. The headstock has two gears on it, the large one (called a bull gear) could be part of a back gear drive along with the smaller one. There would have been a small gear at the end of the spindle along with a bunch of change gears would move the carraige at different thread per inch. So I think you are missing the change gears and the bracket/linkage that attaches them to the headstock to drive the lead screw. You are also missing the back gear drive assembly.

Watch this video. It is about an early screw cutting teadle lathe. It is no where near as old as yours but will explain the parts that are missing. http://video.pbs.org/video/2296983856/ Quote Link to comment Share on other sites More sharing options...
